Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Generally, an outside heat exchanger in a heat pump car air conditioner is generally placed upright and fixedly in front of a vehicle, as is a household appliance. Meanwhile, as the pipeline of the parallel flow heat exchanger adopts the flat pipes, the corrugated cooling fins are arranged between the flat pipes, and condensed water is easy to accumulate in the gaps between the flat pipes and the cooling fins after being condensed on the corrugated cooling fins of the heat exchanger, so that the condensed water is not easy to be discharged; the arrangement mode of the heat exchanger and the structural form of the parallel flow heat exchanger are combined to cause poor drainage performance of the parallel flow heat exchanger, and the parallel flow heat exchanger is limited by the poor drainage performance, and is mainly only used for the heat exchanger outside a single cooling unit and is not suitable for a heat pump air conditioner.
As shown in fig. 1 and 2, an outside heat exchanger of an automobile air conditioner (for example, the outside heat exchanger 1 shown in fig. 1 and 2) is located at the front end of an automobile, so that a higher air flow speed is formed on the surface of the outside heat exchanger when the automobile is running. When the heat pump automobile air conditioner enters a defrosting mode, a large amount of heat for defrosting can be taken away by air flowing at a high speed on the surface of the outer side heat exchanger, so that heat waste of a heat pump air conditioner system is caused, defrosting effect of the heat pump automobile air conditioner can be seriously influenced, even the phenomenon that defrosting cannot be performed is caused, and comfort of passengers in the automobile is influenced.
According to an embodiment of the present invention, there is provided a heat exchange control device, and a schematic structural diagram of an embodiment of the heat exchange control device of the present invention is shown in fig. 3. The heat exchange control device may include: and a rotating device.
The rotating device may be used for rotating the outer heat exchanger 1 of the air conditioner to be controlled to an inclined position according to a set first certain rotation direction, so that the condensed water and/or defrost water condensed on the surface of the outer heat exchanger 1 is discharged by utilizing the gravity of the condensed water and/or defrost water condensed on the surface of the outer heat exchanger 1 and the external flowing air of the outer heat exchanger 1.
For example: as shown in fig. 5, after the heat pump vehicle air conditioner enters the defrosting mode, the program control driving motor 2 drives the outside heat exchanger 1 to rotate to a horizontal position.
Therefore, the outer side heat exchanger is rotated to an inclined or transverse position through the rotating device, so that condensed water and defrosting water condensed on the surface of the outer side parallel flow heat exchanger can be timely and automatically discharged by means of gravity and the air flow influence of the surface of the heat exchanger, wind resistance of the outer side heat exchanger is reduced, and heat exchange performance is improved.
Optionally, the air conditioner to be controlled may include: heat pump car air conditioner.
Optionally, when the air conditioner to be controlled may include a heat pump car air conditioner, the outside heat exchanger 1 is disposed on a front windward side of the heat pump car air conditioner.
For example: the outside heat exchanger 1 is placed on the front windward side of the automobile air conditioner.
Therefore, the outside heat exchanger is arranged on the windward side of the front side of the automobile air conditioner, so that heat exchange is convenient and efficient.
Optionally, when the air conditioner to be controlled may include a heat pump car air conditioner, the first rotation direction may include: and a direction in which the upper part of the outside heat exchanger 1 is rotated toward the rear of the automobile and the lower part of the outside heat exchanger 1 is rotated toward the front of the automobile.
For example: when the outer heat exchanger is inclined, the upper part of the outer heat exchanger is inwards (namely, the tail direction), and the lower part of the heat exchanger is outwards (namely, the head direction) to rotate and incline.
Alternatively, when the air conditioner to be controlled may include a heat pump car air conditioner, the flowing air outside the outdoor heat exchanger may include: the heat pump automobile air conditioner belongs to the front side flow air of the automobile.
Therefore, the upper part of the outer heat exchanger is inclined towards the tail direction, and the lower part of the outer heat exchanger is inclined towards the head direction, so that drainage is facilitated, the drainage efficiency is high, and the heat exchange performance is good.
Alternatively, the outside heat exchanger 1 may include: parallel flow heat exchangers.
Therefore, the parallel flow heat exchanger has small occupied space and high heat exchange efficiency.
In an alternative example, the rotating device may be further configured to rotate the outer heat exchanger 1 to the upright position in a second rotation direction opposite to the first rotation direction, so as to increase the flow rate of the external flowing air of the outer heat exchanger 1, so that the outer heat exchanger 1 exchanges heat normally.
For example: after the defrosting of the heat pump automobile air conditioner is completed, the driving motor rotates the outside parallel flow heat exchanger to the vertical position, and then the heat pump automobile air conditioner is switched to normal heating mode operation, so that the defrosting water can be discharged cleanly by effectively utilizing the air flow at the front side of the automobile.
For example: as shown in fig. 6, after the heat pump vehicle air conditioner enters the cooling mode, the program control driving motor 2 drives the outside heat exchanger 1 to rotate to the upright position.
Therefore, the air flow rate on the surface of the outer heat exchanger can be improved by rotating the outer heat exchanger to the vertical position, so that normal heat exchange is performed, and the heat exchange efficiency is high.
Wherein the included angle between the upright position and the inclined position is greater than or equal to 15 °, and less than or equal to 90 °.
For example: the angle between the vertical position and the inclined position of the outer heat exchanger 1 is alpha, wherein alpha is more than or equal to 15 degrees and less than or equal to 90 degrees.
From this, through reasonable inclination, can promote drainage convenience and high efficiency.
Alternatively, the rotating means may rotate the outside heat exchanger 1 of the air conditioner to be controlled to an inclined position and rotate the outside heat exchanger 1 to an upright position, and may include:
(11) And after the air conditioner to be controlled enters a heating mode or a defrosting mode, the outside heat exchanger 1 is rotated to the inclined position. The method comprises the steps of,
for example: when the heat pump automobile air conditioner is in heat conditioning operation, the heat pump automobile air conditioner outside parallel flow heat exchanger is controlled to rotate to an inclined position, so that water condensed on the surface of the outside parallel flow heat exchanger can be effectively discharged, the wind resistance of the heat exchanger is reduced, and the heat exchange performance is improved.
For example: after the heat pump automobile air conditioner needs to enter a defrosting mode, the heat pump automobile air conditioner is controlled to rotate to an inclined position or a transverse flat position, so that defrosting water after frost on the surface of the heat pump automobile air conditioner is melted can be timely and automatically discharged under the action of gravity, frost can not be re-condensed, and normal heating operation of the heat pump air conditioner is ensured.
For example: after the heat pump automobile air conditioner enters defrosting, as the heat pump automobile air conditioner outside parallel flow heat exchanger rotates to an inclined position or a transverse flat position, the area of the heat exchanger in the airflow direction of the front side of the automobile is reduced, the airflow flowing through the surface of the heat exchanger is correspondingly reduced, the quantity of heat used for defrosting on the surface of the heat exchanger can be taken away by flowing air, the defrosting speed is effectively increased, and the defrosting effect is improved.
For example: when the heating mode or the defrosting mode of the heat pump automobile air conditioner is operated, the outside heat exchanger is rotated to an inclined position or a horizontal flat position, so that condensed water and defrosting water on the surface of the outside heat exchanger can be accelerated to be discharged, and the performance and reliability of the heat pump automobile air conditioner are effectively improved.
For example: the outside heat exchanger 1 can also be in an inclined position after entering the defrost mode, the outside heat exchanger 1 having an angle α between the vertical position and the inclined position, wherein α is 15 ° or more and 90 ° or less.
(12) And after the air conditioner to be controlled is in the heating mode and condensed water condensed on the surface of the outer side heat exchanger 1 is discharged, or after the defrosting water formed after the air conditioner to be controlled is in the defrosting mode and the frost layer on the surface of the outer side heat exchanger 1 is melted is discharged, or after the air conditioner to be controlled finishes defrosting in the defrosting mode, the outer side heat exchanger 1 is rotated to the vertical position.
For example: and after the condensed water is discharged, the outside parallel flow heat exchanger is rotated to an upright position, so that the normal heat exchange of the heat exchanger is not affected.
For example: after defrosting operation is finished, the driving motor rotates the outside parallel flow heat exchanger to an upright position, and then the heat pump automobile air conditioner is switched to normal heating mode operation, so that defrosting water can be discharged cleanly by effectively utilizing air flow at the front side of the automobile.
Therefore, the resistance of the surface of the outer heat exchanger in the corresponding mode can be reduced, the heat exchange performance and the running performance can be improved by rotating the outer heat exchanger to the inclined position or the vertical position according to the mode of the air conditioner, and the energy conservation and the reliability of the running of the air conditioner can be improved.
Alternatively, the rotating device rotates the outside heat exchanger 1 of the air conditioner to be controlled to an inclined position and rotates the outside heat exchanger 1 to an upright position, and may further include:
(21) And after the air conditioner to be controlled enters a heating mode, the outside heat exchanger 1 is rotated to the inclined position and kept for a first set period of time. The method comprises the steps of,
(22) And after the first set time period is reached, the outer side heat exchanger 1 is rotated to the vertical position and kept for a second set time period. The method comprises the steps of,
(23) And after the second set time period is reached, the outer side heat exchanger 1 is rotated to the inclined position and the first set time period is maintained.
For example: when the heat pump air conditioner is in heating operation, the program control driving motor rotates the outer side parallel flow heat exchanger to an inclined position according to a certain period, condensed water on the surface of the outer side heat exchanger is condensed to a certain degree, and then the condensed water can be timely and automatically discharged, so that the wind resistance of the heat exchanger can be reduced, and the heat exchange performance is improved.
For example: the program-controlled driving motor 2 may rotate the outside heat exchanger 1 from the upright position to the inclined position for a holding time T1 at a predetermined period, reversely rotate the outside heat exchanger 1 to the upright position after the holding time T1, and reversely rotate the outside heat exchanger 1 to the inclined position after the holding time T2, and reciprocally rotate the outside heat exchanger. The outside heat exchanger 1 is kept at an inclined position for a time T1, so that condensed water condensed on the outside heat exchanger 1 can be discharged; after the outer heat exchanger 1 resumes the rotation to the upright position, the air flow rate on the surface of the outer heat exchanger 1 can be improved, and the heat exchange performance of the outer heat exchanger 1 is ensured.
Therefore, the outside heat exchanger can be periodically drained by periodically rotating to an inclined position or an upright position, and the operation reliability and the heat exchange effect of the air conditioner can be improved.
In an alternative example, the number of rotation means is two. The two rotating devices are arranged on two sides of the outer heat exchanger 1 along the refrigerant flow direction of the outer heat exchanger 1 in opposite directions.
Therefore, the two rotating devices are arranged at the two ends of the outer heat exchanger along the refrigerant flow direction, so that the rotation is convenient, and the drainage is convenient.
Optionally, the rotating device may include: and a support shaft 4.
The support shaft 4 is fixedly disposed at one side of the outer heat exchanger 1 along the refrigerant flow direction of the outer heat exchanger 1.
For example: the two ends of the outside heat exchanger 1 are respectively provided with a supporting shaft 4, and the supporting shafts 4 are transversely arranged and integrally connected and fixed with the outside heat exchanger.
Therefore, the support shaft is fixedly arranged at the end part of the outer heat exchanger, so that the outer heat exchanger can rotate along with the support shaft more reliably and stably.
More optionally, when the number of the rotating means is two, the axes of the two support shafts 4 in the two rotating means are on the same axis.
Wherein, the same axis where the axes of the two support shafts 4 are located may include: the outer heat exchanger 1 is arranged along the center line of the refrigerant flow direction.
For example: the axes of the two support shafts 4 are on the same axis.
Therefore, the shaft centers of the two support shafts are coaxially arranged, so that the rotation convenience and reliability can be improved, and the power can be saved.
Optionally, the rotating device may further include: and a bearing 3.
In an alternative specific example, the bearing 3 is fixedly arranged at other parts of the air conditioner to be controlled and is matched with the supporting shaft 4, so that the bearing can be used for supporting and fixing the outside heat exchanger 1.
More optionally, when the air conditioner to be controlled may include a heat pump car air conditioner, the bearing 3 is fixedly disposed on a frame of a car to which the heat pump car air conditioner belongs.
More optionally, when the number of the rotating devices is two, two bearings 3 in the two rotating devices are disposed opposite to each other along the refrigerant flow direction of the outer heat exchanger 1.
For example: a pair of bearings 3 arranged opposite to each other are arranged on the frames at the two ends of the outer heat exchanger 1, and the bearings 3 are fixed on the automobile frame. The bearing 3 is matched with the supporting shafts 4 arranged on two sides of the outer heat exchanger 1 to support and fix the outer heat exchanger 1.
For example: the driving motor 2 is connected with the supporting shaft 4 on one side of the outer side heat exchanger 1, and the driving motor 2 operates to drive the outer side heat exchanger 1 to rotate around the supporting shaft 4, so that the outer side heat exchanger 1 can be in an inclined position or a horizontal flat position.
Therefore, the bearing is arranged in cooperation with the support shaft, so that the outside heat exchanger can rotate along with the support shaft more reliably and safely.
In an alternative embodiment, the method may further include: a driving device.
In an alternative example, the driving means may be used to drive the rotating means.
From this, drive rotary device through drive arrangement for it is more convenient, more controllable to rotate, simple structure, and uses manpower sparingly.
In an alternative example, when the number of the rotating means is two, the driving means is provided at a side of one of the rotating means remote from the outside heat exchanger 1.
Therefore, by arranging the driving motor for only one rotating device, on one hand, the reliability and the synchronism of the driving of the rotating device are ensured, and the control is convenient; on the other hand, one driving motor can be saved, and the energy-saving effect is good.
Optionally, the driving device may include: the motor 2 is driven.
Wherein, when the rotating device can comprise a support shaft 4, the driving motor 2 is matched with the support shaft 4.
For example: after the heat pump air conditioner enters a defrosting mode, the program control driving motor rotates the outer side parallel flow heat exchanger to an inclined or transverse flat position, defrosting water formed after the surface frost layer of the outer side heat exchanger is melted can be automatically and timely discharged, frost can not be formed by re-condensation, and normal heating operation of the heat pump air conditioner is ensured.
For example: when the heat pump automobile air conditioner enters a heating mode, the program control driving motor 2 drives the outer side heat exchanger 1 to rotate to an inclined position.
Therefore, the rotating device is driven by the driving motor, the driving mode is simple and convenient, and the reliability is high.
In an alternative embodiment, the method may further include: a flexible communication device.
In an alternative example, the flexible communication device may be used to communicate the heat exchange pipeline of the outside heat exchanger 1 with other parts of the air conditioner to be controlled.
When the air conditioner to be controlled can comprise a heat pump automobile air conditioner, the flexible communication device can be used for communicating the heat exchange pipeline of the outside heat exchanger 1 with other parts of the heat pump automobile air conditioner.
Therefore, the outside heat exchanger can rotate more conveniently and flexibly through the flexible communication device, other parts cannot be influenced, and the reliability is high.
In an alternative example, the number of flexible communication means is two. And the two flexible communication devices are respectively communicated with an inlet pipe joint and an outlet pipe joint of the heat exchange pipeline of the outer heat exchanger 1.
The inlet pipe joint and the outlet pipe joint are arranged on one side of the outer heat exchanger 1 along the refrigerant flow direction of the outer heat exchanger 1 at the same time, or are arranged on two sides of the outer heat exchanger 1 along the refrigerant flow direction of the outer heat exchanger 1.
For example: two outside heat exchanger pipe joints 1a are arranged on the outside heat exchanger 1, and the two pipe joints are respectively positioned at the upper part and the lower part of the same side of the outside heat exchanger 1.
For example: when the refrigerating mode or the defrosting mode is operated, the upper pipe joint is an inlet of the outer side heat exchanger 1, and the lower pipe joint is an outlet of the outer side heat exchanger 1; when the heating mode is operated, the upper pipe joint is the outlet of the outside heat exchanger 1, and the lower pipe joint is the inlet of the outside heat exchanger 1.
From this, through setting up two flexible intercommunication devices, with outside heat exchanger's import and export intercommunication respectively for outside heat exchanger's rotation is more nimble, more convenient, and can not influence outside heat exchanger and heat pump vehicle air conditioner's other parts, and the reliability is high.
Optionally, the flexible communication device may include: and a rubber hose 5.
For example: the outside parallel flow heat exchanger is arranged to be capable of rotating around the supporting shaft, the motor drives the parallel flow heat exchanger, the inlet pipe and the outlet pipe joint are connected with the rubber hose, and the outside parallel flow heat exchanger is freely rotated to an inclined or transverse position, so that condensed water and defrosting water condensed on the surface of the outside parallel flow heat exchanger can be timely and automatically discharged by means of gravity and the air flow influence of the surface of the heat exchanger.
For example: to facilitate the rotation of the heat exchanger, a hose (e.g., rubber hose 5) connection is employed. Fig. 3 is a schematic structural diagram of an external heat exchanger device for a heat pump automobile air conditioner, wherein the external heat exchanger device is composed of an external heat exchanger 1, a driving motor 2, a bearing 3, a supporting shaft 4 and a rubber hose 5.
For example: the two outer side heat exchanger pipe joints 1a are connected with a rubber hose 5, and the outer side heat exchanger 1 is connected with other system parts of the heat pump automobile air conditioner through the rubber hose 5 to form a refrigerant circulation system.
Therefore, the heat exchange pipeline of the outside heat exchanger is communicated with other parts of the heat pump automobile air conditioner by adopting the rubber hose, so that the heat pump automobile air conditioner is convenient to rotate, safe and reliable.
More optionally, the length of the rubber hose 5 leaves a set margin on the basis of the set length with the outside heat exchanger 1 in the upright position.
For example: the length of the rubber hose 5 is provided with a certain allowance, the rubber hose 5 can be freely bent and stretched, and when the driving motor 2 drives the outer side heat exchanger 1 to rotate, the rubber hose 5 cannot influence the rotation of the outer side heat exchanger 1.
Therefore, the length of the rubber hose is left with allowance, so that the outside heat exchanger can rotate more freely and flexibly, the outside heat exchanger and other parts of the heat pump automobile air conditioner are not influenced, and the rotation reliability of the outside heat exchanger is ensured.
More optionally, the rubber hose 5 may include: the outer adhesive layer, the yarn layer, the inner adhesive layer and the lining layer are sequentially arranged from outside to inside.
In a more alternative specific example, the material of the outer glue layer may include: ethylene propylene diene monomer.
In a more alternative specific example, the material of the yarn layer may include: at least one of polyester and P polyethylene terephthalate.
In a more alternative specific example, the material of the inner glue layer may include: ethylene propylene diene monomer.
In a more alternative specific example, the material of the liner may include: a polyamide.
For example: the rubber hose that adopts can include: the outer adhesive layer, the yarn layer, the inner adhesive layer and the lining layer are sequentially arranged from outside to inside. The outer adhesive layer can be made of black, weather-proof, ozone-proof, oil-proof, high-temperature and low-temperature-resistant materials, such as EPDM (ethylene propylene diene monomer). The yarn layer can be made of terylene, PET (polyethylene terephthalate) and other materials. The inner adhesive layer can be made of black, permeation-resistant, high and low temperature-resistant, cold-resistant materials, such as EPDM (ethylene propylene diene monomer). The lining layer can be made of white heat-resistant, oil-resistant, permeation-resistant material, such as PA (polyamide).
Therefore, the rubber hose formed by laminating the outer adhesive layer, the yarn layer, the inner adhesive layer and the lining layer by layer is good in flexibility, firm and safe.
In an alternative embodiment, the outside heat exchanger 1 may include: more than two outer side sub-heat exchangers.
More than two outer sub-heat exchangers are arranged in parallel, and the functions of the outer heat exchanger 1 can be independently realized.
In an alternative example, at least one of the outer sub-heat exchangers of the two or more outer sub-heat exchangers is arranged in cooperation with the rotating device and can be used for performing the rotation under the drive of the rotating device.
In an alternative example, at least one other of the two or more outer sub-heat exchangers is fixedly arranged and can be used for performing the normal heat exchange.
Therefore, the outside heat exchanger is divided into a plurality of parts to be arranged, so that the rotating space can be saved, and the rotating flexibility and convenience are improved.
Optionally, the outer sub-heat exchanger of more than two parts may include: an outer upper heat exchanger 12 and an outer lower heat exchanger 11.
In an alternative specific example, the outer upper heat exchanger 12 and the outer lower heat exchanger 11 are respectively matched with the rotating devices, and can independently rotate under the driving of the respective rotating devices.
For example: referring to the example shown in fig. 7, the outer parallel flow heat exchangers can be further arranged into an upper part and a lower part which are separated, and the two parts of heat exchangers rotate around the respective supporting shafts.
For example: if the heat exchanger is divided into two parts, after the heat exchanger rotates into a horizontal direction, the space occupied by the heat exchanger in the horizontal direction is half of the height dimension of the whole heat exchanger.
Wherein, when the heat exchange control device may further include a driving device and the driving device may include a driving motor 2, the driving motor 2 may include: an upper drive motor 22 and a lower drive motor 21. The upper driving motor 22 is arranged in cooperation with the rotating device arranged in cooperation with the outer upper heat exchanger 12. The lower driving motor 21 is arranged in cooperation with the rotating device arranged in cooperation with the outer lower heat exchanger 11.
For example: as shown in fig. 7, the difference between the present alternative embodiment and the preferred embodiment is that: the outer heat exchanger 1 is divided into an outer upper heat exchanger 12 and an outer lower heat exchanger 11, and the two heat exchangers are respectively provided with an upper driving motor 22 and a lower driving motor 21, and are also respectively provided with parts such as a supporting shaft, a bearing and the like. The two parts of heat exchangers can rotate around the supporting shafts respectively and independently. The heat exchanger is divided into an upper part and a lower part, so that the size of the heat exchanger in the vertical direction is reduced, and the occupied transverse space is small and the structure is more compact when the heat exchanger rotates to a horizontal transverse position.
Therefore, the outside heat exchangers are arranged separately and rotate independently, so that the occupied space in the rotating process can be saved, and the rotating flexibility can be improved.
Or, the outer upper heat exchanger 12 is fixedly arranged, and the outer lower heat exchanger 11 is matched with the rotating device and can rotate under the driving of the rotating device.
Wherein, when the heat exchange control device may further include a driving device and the driving device may include a driving motor 2, the driving motor 2 may include: the lower part drives the motor 21. The lower driving motor 21 is arranged in cooperation with the rotating device arranged in cooperation with the outer lower heat exchanger 11.
For example: referring to the example shown in fig. 8, the outside parallel flow heat exchanger is provided as separate upper and lower parts, wherein the upper part heat exchanger is maintained in a fixed upright state, the lower part heat exchanger is provided to be rotatable about its support shaft, the space required for rotation is reduced, the structure is more compact, and the support shaft, bearings, driving motor, etc. of the upper part heat exchanger are eliminated, and the structure is simpler and the cost is lower.
For example: as shown in fig. 8, the present alternative embodiment differs from the first alternative embodiment in that: the outer upper heat exchanger 12 is in a fixed non-rotating state, the outer lower heat exchanger 11 is provided with parts such as a lower driving motor 21, a supporting shaft, a bearing and the like, and the outer lower heat exchanger 11 can rotate around the supporting shaft. When the outer heat exchanger 1 heats, the outer heat exchanger serves as an evaporator to absorb heat by evaporation, at the moment, the upper pipe joint is an outlet of the outer heat exchanger 1, and the lower pipe joint is an inlet of the outer heat exchanger 1. Because the refrigerant flows from bottom to top, the lower half of the outer heat exchanger is easier to form condensed water and frost, and therefore after the outer heat exchanger is divided into two parts, the condensed water and frost are formed from the outer lower heat exchanger 11 at first and mainly gathered in the outer lower heat exchanger 11. The condensed water and the defrost water on the outer lower heat exchanger can be discharged only by controlling the outer lower heat exchanger 11 to rotate to an inclined position or a horizontal flat position in the heating mode or the defrosting mode, and the same functions as described in the optimal embodiment are realized. Moreover, the transverse space occupied by the scheme is small, the structure is more compact, the supporting shaft, the bearing, the driving motor and the like of the upper part heat exchanger are eliminated, the structure is simpler, and the cost is lower.
Therefore, the lower part heat exchanger is rotated, the upper part heat exchanger is fixed, the rotating space can be saved, the rotating cost can be saved, and the use convenience and the humanization are good.
Through a large number of experiments, the technical scheme of the embodiment is adopted, when the heat pump automobile air conditioner is in heating operation, the heat pump automobile air conditioner outside parallel flow heat exchanger is controlled to rotate to an inclined position, so that water condensed on the surface of the outside parallel flow heat exchanger can be effectively discharged, the wind resistance of the heat exchanger is reduced, and the heat exchange performance is improved.
According to an embodiment of the present invention, there is also provided an air conditioner corresponding to the heat exchange control device. The air conditioner may include: the heat exchange control device is described above.
In an alternative embodiment, the external parallel flow heat exchanger can be set to rotate around the supporting shaft, the motor drives the inlet pipe and the outlet pipe joint of the parallel flow heat exchanger to be connected with the rubber hose, and the external parallel flow heat exchanger can be freely rotated to an inclined or transverse position, so that condensed water and defrosting water condensed on the surface of the external parallel flow heat exchanger can be timely and automatically discharged under the influence of gravity and air flow on the surface of the heat exchanger.
The connection between the inlet and the outlet of the heat exchanger (i.e. the outer heat exchanger 1, such as a parallel flow heat exchanger) is generally fixedly connected by an aluminum tube, because the outer heat exchanger is usually in a fixed state, and a rubber hose is not needed. Here, in order to facilitate the rotation of the heat exchanger, a hose (e.g., rubber hose 5) connection is employed.
For example: the rubber hose that adopts can include: the outer adhesive layer, the yarn layer, the inner adhesive layer and the lining layer are sequentially arranged from outside to inside. The outer adhesive layer can be made of black, weather-proof, ozone-proof, oil-proof, high-temperature and low-temperature-resistant materials, such as EPDM (ethylene propylene diene monomer). The yarn layer can be made of terylene, PET (polyethylene terephthalate) and other materials. The inner adhesive layer can be made of black, permeation-resistant, high and low temperature-resistant, cold-resistant materials, such as EPDM (ethylene propylene diene monomer). The lining layer can be made of white heat-resistant, oil-resistant, permeation-resistant material, such as PA (polyamide).
In an alternative example, when the heat pump automobile air conditioner is in heat-conditioning operation, water condensed on the surface of the outer parallel flow heat exchanger can be accumulated on the fins and the flat tubes, so that the wind resistance of the heat exchanger is increased, and the heat transfer performance is reduced. In order to solve the problem, when the heat pump automobile air conditioner is in heat conditioning operation, the heat pump automobile air conditioner outside parallel flow heat exchanger is controlled to rotate to an inclined position, so that water condensed on the surface of the outside parallel flow heat exchanger can be effectively discharged, the wind resistance of the heat exchanger is reduced, and the heat exchange performance is improved.
Specifically, when the heat pump air conditioner is in heating operation, the program control driving motor rotates the outer side parallel flow heat exchanger to an inclined position according to a certain period, condensed water on the surface of the outer side heat exchanger is condensed to a certain degree and then can be discharged timely and automatically, so that the wind resistance of the heat exchanger can be reduced, and the heat exchange performance is improved; and after the condensed water is discharged, the outside parallel flow heat exchanger is rotated to an upright position, so that the normal heat exchange of the heat exchanger is not affected.
Wherein, the water discharged by oneself can not influence other parts of the automobile when the vehicle runs at high speed. In general, an outside heat exchanger of an automobile air conditioner may have rainwater entering in a rainy day, and parts behind and below the heat exchanger (for example, the outside heat exchanger 1) are waterproof when the automobile air conditioner is designed.
Optionally, after the heat pump automobile air conditioner enters a defrosting mode, defrosting water formed after frost on the surface of the outside parallel flow heat exchanger is melted cannot be discharged in time, and after the operation in the hot mode is resumed, the defrosting water can be frozen and condensed into ice, so that the frosting condition of the outside heat exchanger is aggravated, and the normal heating operation of the heat pump air conditioner is affected. In order to solve the problem, after the heat pump automobile air conditioner needs to enter a defrosting mode, the heat pump automobile air conditioner outside parallel flow heat exchanger is controlled to rotate to an inclined position or a horizontal flat position, so that defrosting water after frost on the surface of the outside parallel flow heat exchanger is melted can be timely discharged by itself under the action of gravity, frost can not be re-condensed, and normal heating operation of the heat pump air conditioner is ensured. The problem that the parallel flow heat exchanger cannot be used as an outside heat exchanger for a heat pump automobile air conditioner is solved.
Further, after the heat pump automobile air conditioner enters a defrosting mode (namely a defrosting mode), the air flow at the front side of the automobile takes away a large amount of heat for defrosting on the surface of the heat exchanger at the outer side, so that the defrosting speed is slow, the defrosting effect is poor, and even the phenomenon that defrosting is impossible occurs. In order to solve the problem, after the heat pump automobile air conditioner enters defrosting, as the heat pump automobile air conditioner outside parallel flow heat exchanger rotates to an inclined position or a horizontal flat position, the area of the heat exchanger in the airflow direction of the front side of the automobile is reduced, the air flow flowing through the surface of the heat exchanger is correspondingly reduced, the heat quantity of the surface of the heat exchanger for defrosting can be taken away by flowing air, the defrosting speed is effectively increased, and the defrosting effect is improved.
Specifically, after the heat pump air conditioner enters a defrosting mode, a program control driving motor rotates an outer side parallel flow heat exchanger to an inclined or transverse flat position, defrosting water formed after the surface frost layer of the outer side heat exchanger is melted can be automatically and timely discharged, frost can not be re-condensed, and normal heating operation of the heat pump air conditioner is ensured; after defrosting operation is finished, the driving motor rotates the outside parallel flow heat exchanger to an upright position, and then the heat pump automobile air conditioner is switched to normal heating mode operation, so that defrosting water can be discharged cleanly by effectively utilizing air flow at the front side of the automobile.
The inclination angle of the outer parallel flow heat exchanger may be an angle range of greater than 0 degrees and less than or equal to 90 degrees.
In an alternative example, referring to the example shown in fig. 7, the outer parallel flow heat exchangers may be further configured as separate upper and lower parts, and the two parts of heat exchangers rotate around respective support shafts, so that when the driving motor drives the heat exchangers to rotate to a horizontal position due to the smaller size of each heat exchanger, the required space is reduced, and the structure is more compact.
The upper and lower heat exchangers can be separated or not. The space can be saved mainly by the separate arrangement.
For example: as can be seen from comparison between fig. 5 and fig. 7, if the heat exchanger is not divided into two parts, the space occupied by the heat exchanger in the horizontal direction is the height dimension of the whole heat exchanger after rotating into the horizontal direction, and if the heat exchanger is divided into two parts, the space occupied by the heat exchanger in the horizontal direction is half of the height dimension of the whole heat exchanger after rotating into the horizontal direction.
In an alternative example, see the example shown in fig. 8, the outside parallel flow heat exchanger is arranged as upper and lower separate parts, wherein the upper part heat exchanger is kept in a fixed and upright state, the lower part heat exchanger is arranged to rotate around its supporting shaft, the space required for rotation is reduced, the structure is more compact, and the supporting shaft, the bearing, the driving motor and the like of the upper part heat exchanger are eliminated, so that the structure is simpler and the cost is lower.
In an alternative embodiment, in the scheme of the invention, the rotatable outer side heat exchanger device for the heat pump automobile air conditioner mainly rotates the outer side heat exchanger to an inclined position or a horizontal flat position when the heat pump automobile air conditioner is operated in a heating mode or a defrosting mode, so that condensed water and defrosting water on the surface of the outer side heat exchanger can be discharged quickly, and the performance and reliability of the heat pump automobile air conditioner are improved effectively.
Alternatively, as shown in fig. 3, a schematic structural diagram of an external heat exchanger device for a heat pump automobile air conditioner is shown, and the external heat exchanger device is composed of an external heat exchanger 1, a driving motor 2, a bearing 3, a supporting shaft 4 and a rubber hose 5.
The outside heat exchanger 1 is arranged on the windward side of the front side of the automobile air conditioner, two outside heat exchanger pipe joints 1a are arranged on the outside heat exchanger 1, and the two pipe joints are respectively positioned at the upper part and the lower part of the same side of the outside heat exchanger 1; the two outer side heat exchanger pipe joints 1a are connected with a rubber hose 5, and the outer side heat exchanger 1 is connected with other system parts of the heat pump automobile air conditioner through the rubber hose 5 to form a refrigerant circulation system. When the refrigerating mode or the defrosting mode is operated, the upper pipe joint is an inlet of the outer side heat exchanger 1, and the lower pipe joint is an outlet of the outer side heat exchanger 1; when the heating mode is operated, the upper pipe joint is the outlet of the outside heat exchanger 1, and the lower pipe joint is the inlet of the outside heat exchanger 1.
In an alternative specific example, two ends of the outer heat exchanger 1 are respectively provided with a supporting shaft 4, the supporting shafts 4 are transversely arranged and integrally connected and fixed with the outer heat exchanger, and the axes of the two supporting shafts 4 are on the same axis.
In an alternative specific example, a pair of bearings 3 are provided on the frame at both end portions of the outside heat exchanger 1, the bearings 3 being fixed to the vehicle frame. The bearing 3 is matched with the supporting shafts 4 arranged on two sides of the outer heat exchanger 1 to support and fix the outer heat exchanger 1.
In an alternative specific example, the driving motor 2 is connected with the supporting shaft 4 on one side of the outer side heat exchanger 1, and the outer side heat exchanger 1 can be placed in an inclined position or a transverse flat position by operating the driving motor 2 to drive the outer side heat exchanger 1 to rotate around the supporting shaft 4.
In an alternative specific example, a certain margin is provided for the length of the rubber hose 5, the rubber hose 5 can be freely bent and stretched, and the rubber hose 5 does not influence the rotation of the external heat exchanger 1 when the driving motor 2 drives the external heat exchanger 1 to rotate.
In an alternative example, the operation process and control method of the outer heat exchanger device (i.e., the heat exchange control device) are as follows:
Alternatively, as shown in fig. 4, after the heat pump vehicle air conditioner enters the heating mode, the program control driving motor 2 drives the outside heat exchanger 1 to rotate to the inclined position, and the included angle between the vertical position and the inclined position of the outside heat exchanger 1 is alpha, wherein alpha is more than or equal to 15 degrees and less than or equal to 90 degrees. For example: when α is small, it may be less than or equal to 23 °; when α is large, it may be larger than 23 °.
Specifically, when the outer heat exchanger is inclined, the upper part of the outer heat exchanger is inward (i.e. in the tail direction), and the lower part of the heat exchanger is inclined in a rotating manner outwards (i.e. in the head direction).
The program-controlled driving motor 2 may rotate the outer heat exchanger 1 from the upright position to the inclined position for a holding time T1 at a predetermined period, reversely rotate the outer heat exchanger 1 to the upright position after the holding time T1, and rotate the outer heat exchanger 1 to the inclined position after the holding time T2, and reciprocally rotate the outer heat exchanger. The outside heat exchanger 1 is kept at an inclined position for a time T1, so that condensed water condensed on the outside heat exchanger 1 can be discharged; after the outer heat exchanger 1 resumes the rotation to the upright position, the air flow rate on the surface of the outer heat exchanger 1 can be improved, and the heat exchange performance of the outer heat exchanger 1 is ensured.
Alternatively, as shown in fig. 5, after the heat pump vehicle air conditioner enters the defrosting mode, the program control driving motor 2 drives the outside heat exchanger 1 to rotate to the horizontal position. After the defrosting of the heat pump automobile air conditioner is completed, the driving motor rotates the outside parallel flow heat exchanger to the vertical position, and then the heat pump automobile air conditioner is switched to normal heating mode operation, so that the defrosting water can be discharged cleanly by effectively utilizing the air flow at the front side of the automobile.
Wherein the outside heat exchanger 1 can also be in an inclined position after entering the defrosting mode, and the included angle between the vertical position and the inclined position of the outside heat exchanger 1 is alpha, wherein alpha is more than or equal to 15 degrees and less than or equal to 90 degrees.
Alternatively, as shown in fig. 6, after the heat pump vehicle air conditioner enters the cooling mode, the program control driving motor 2 drives the outside heat exchanger 1 to rotate to the upright position.
In an alternative example, as shown in fig. 7, the difference between the present alternative embodiment and the best mode is that: the outer heat exchanger 1 is divided into an outer upper heat exchanger 12 and an outer lower heat exchanger 11, and the two heat exchangers are respectively provided with an upper driving motor 22 and a lower driving motor 21, and are also respectively provided with parts such as a supporting shaft, a bearing and the like. The two parts of heat exchangers can rotate around the supporting shafts respectively and independently.
The heat exchanger is divided into an upper part and a lower part, so that the size of the heat exchanger in the vertical direction is reduced, and the occupied transverse space is small and the structure is more compact when the heat exchanger rotates to a horizontal transverse position.
In an alternative example, as shown in fig. 8, the difference between the present alternative embodiment and the first alternative embodiment is that: the outer upper heat exchanger 12 is in a fixed non-rotating state, the outer lower heat exchanger 11 is provided with parts such as a lower driving motor 21, a supporting shaft, a bearing and the like, and the outer lower heat exchanger 11 can rotate around the supporting shaft.
When the outer heat exchanger 1 heats, the outer heat exchanger serves as an evaporator to absorb heat by evaporation, at the moment, the upper pipe joint is an outlet of the outer heat exchanger 1, and the lower pipe joint is an inlet of the outer heat exchanger 1. Because the refrigerant flows from bottom to top, the lower half of the outer heat exchanger is easier to form condensed water and frost, and therefore after the outer heat exchanger is divided into two parts, the condensed water and frost are formed from the outer lower heat exchanger 11 at first and mainly gathered in the outer lower heat exchanger 11. The condensed water and the defrost water on the outer lower heat exchanger can be discharged only by controlling the outer lower heat exchanger 11 to rotate to an inclined position or a horizontal flat position in the heating mode or the defrosting mode, and the same functions as described in the optimal embodiment are realized.
Moreover, the transverse space occupied by the scheme is small, the structure is more compact, the supporting shaft, the bearing, the driving motor and the like of the upper part heat exchanger are eliminated, the structure is simpler, and the cost is lower.
Since the processing and the functions implemented by the air conditioner of the present embodiment basically correspond to the embodiments, principles and examples of the heat exchange control device shown in fig. 3 to 8, the description of the present embodiment is not exhaustive, and reference may be made to the related descriptions in the foregoing embodiments, which are not repeated herein.
Through a large number of experiments, the technical scheme of the invention is adopted, after the heat pump automobile air conditioner needs to enter a defrosting mode, the parallel flow heat exchanger at the outer side of the heat pump automobile air conditioner is controlled to rotate to an inclined position or a transverse flat position, so that defrosting water after frost on the surface of the parallel flow heat exchanger at the outer side is melted can be timely and automatically discharged under the action of gravity, frost can not be re-condensed, normal heating operation of the heat pump air conditioner is ensured, and the problem that the parallel flow heat exchanger cannot be used as the heat pump automobile air conditioner is solved.
According to an embodiment of the present invention, there is also provided a heat exchange control method of an air conditioner corresponding to the air conditioner. The heat exchange control method of the air conditioner may include: according to a set first certain rotation direction, the outer side heat exchanger 1 of the air conditioner to be controlled is rotated to an inclined position, so that the condensed water and/or defrosting water condensed on the surface of the outer side heat exchanger 1 are discharged by utilizing the gravity of the condensed water and/or defrosting water condensed on the surface of the outer side heat exchanger 1 and the external flowing air of the outer side heat exchanger 1.
For example: as shown in fig. 5, after the heat pump vehicle air conditioner enters the defrosting mode, the program control driving motor 2 drives the outside heat exchanger 1 to rotate to a horizontal position.
Therefore, the outer side heat exchanger is rotated to an inclined or transverse position through the rotating device, so that condensed water and defrosting water condensed on the surface of the outer side parallel flow heat exchanger can be timely and automatically discharged by means of gravity and the air flow influence of the surface of the heat exchanger, wind resistance of the outer side heat exchanger is reduced, and heat exchange performance is improved.
In an alternative embodiment, the method may further include: and rotating the outer heat exchanger 1 to an upright position according to a second rotation direction opposite to the first rotation direction so as to increase the flow rate of the external flowing air of the outer heat exchanger 1 and enable the outer heat exchanger 1 to exchange heat normally.
For example: after the defrosting of the heat pump automobile air conditioner is completed, the driving motor rotates the outside parallel flow heat exchanger to the vertical position, and then the heat pump automobile air conditioner is switched to normal heating mode operation, so that the defrosting water can be discharged cleanly by effectively utilizing the air flow at the front side of the automobile.
For example: as shown in fig. 6, after the heat pump vehicle air conditioner enters the cooling mode, the program control driving motor 2 drives the outside heat exchanger 1 to rotate to the upright position.
Therefore, the air flow rate on the surface of the outer heat exchanger can be improved by rotating the outer heat exchanger to the vertical position, so that normal heat exchange is performed, and the heat exchange efficiency is high.
In an alternative example, rotating the outside heat exchanger 1 of the air conditioner to be controlled to an inclined position and rotating the outside heat exchanger 1 to an upright position may include:
step S110, after the air conditioner to be controlled enters a heating mode or a defrosting mode, rotating the outside heat exchanger 1 to the inclined position. The method comprises the steps of,
for example: when the heat pump automobile air conditioner is in heat conditioning operation, the heat pump automobile air conditioner outside parallel flow heat exchanger is controlled to rotate to an inclined position, so that water condensed on the surface of the outside parallel flow heat exchanger can be effectively discharged, the wind resistance of the heat exchanger is reduced, and the heat exchange performance is improved.
For example: after the heat pump automobile air conditioner needs to enter a defrosting mode, the heat pump automobile air conditioner is controlled to rotate to an inclined position or a transverse flat position, so that defrosting water after frost on the surface of the heat pump automobile air conditioner is melted can be timely and automatically discharged under the action of gravity, frost can not be re-condensed, and normal heating operation of the heat pump air conditioner is ensured.
For example: after the heat pump automobile air conditioner enters defrosting, as the heat pump automobile air conditioner outside parallel flow heat exchanger rotates to an inclined position or a transverse flat position, the area of the heat exchanger in the airflow direction of the front side of the automobile is reduced, the airflow flowing through the surface of the heat exchanger is correspondingly reduced, the quantity of heat used for defrosting on the surface of the heat exchanger can be taken away by flowing air, the defrosting speed is effectively increased, and the defrosting effect is improved.
For example: when the heating mode or the defrosting mode of the heat pump automobile air conditioner is operated, the outside heat exchanger is rotated to an inclined position or a horizontal flat position, so that condensed water and defrosting water on the surface of the outside heat exchanger can be accelerated to be discharged, and the performance and reliability of the heat pump automobile air conditioner are effectively improved.
For example: the outside heat exchanger 1 can also be in an inclined position after entering the defrost mode, the outside heat exchanger 1 having an angle α between the vertical position and the inclined position, wherein α is 15 ° or more and 90 ° or less.
Step S120, after the air conditioner to be controlled is in the heating mode and condensed water condensed on the surface of the outside heat exchanger 1 is drained, or after the air conditioner to be controlled is in the defrosting mode and the defrosting water formed after the frost layer on the surface of the outside heat exchanger 1 is melted is drained, or after the air conditioner to be controlled finishes defrosting in the defrosting mode, rotating the outside heat exchanger 1 to the upright position.
For example: and after the condensed water is discharged, the outside parallel flow heat exchanger is rotated to an upright position, so that the normal heat exchange of the heat exchanger is not affected.
For example: after defrosting operation is finished, the driving motor rotates the outside parallel flow heat exchanger to an upright position, and then the heat pump automobile air conditioner is switched to normal heating mode operation, so that defrosting water can be discharged cleanly by effectively utilizing air flow at the front side of the automobile.
Therefore, the resistance of the surface of the outer heat exchanger in the corresponding mode can be reduced, the heat exchange performance and the running performance can be improved by rotating the outer heat exchanger to the inclined position or the vertical position according to the mode of the air conditioner, and the energy conservation and the reliability of the running of the air conditioner can be improved.
Alternatively, the rotating device rotates the outside heat exchanger 1 of the air conditioner to be controlled to an inclined position and rotates the outside heat exchanger 1 to an upright position, and may further include:
step S210, after the air conditioner to be controlled enters the heating mode, rotating the outside heat exchanger 1 to the inclined position and maintaining the first set period of time. The method comprises the steps of,
step S220, after the first set period of time is reached, rotating the outside heat exchanger 1 to the upright position and maintaining the second set period of time. The method comprises the steps of,
step S230, after the second set period of time arrives, rotating the outside heat exchanger 1 to the inclined position and maintaining the first set period of time.
For example: when the heat pump air conditioner is in heating operation, the program control driving motor rotates the outer side parallel flow heat exchanger to an inclined position according to a certain period, condensed water on the surface of the outer side heat exchanger is condensed to a certain degree, and then the condensed water can be timely and automatically discharged, so that the wind resistance of the heat exchanger can be reduced, and the heat exchange performance is improved.
For example: the program-controlled driving motor 2 may rotate the outside heat exchanger 1 from the upright position to the inclined position for a holding time T1 at a predetermined period, reversely rotate the outside heat exchanger 1 to the upright position after the holding time T1, and reversely rotate the outside heat exchanger 1 to the inclined position after the holding time T2, and reciprocally rotate the outside heat exchanger. The outside heat exchanger 1 is kept at an inclined position for a time T1, so that condensed water condensed on the outside heat exchanger 1 can be discharged; after the outer heat exchanger 1 resumes the rotation to the upright position, the air flow rate on the surface of the outer heat exchanger 1 can be improved, and the heat exchange performance of the outer heat exchanger 1 is ensured.
Therefore, the outside heat exchanger can be periodically drained by periodically rotating to an inclined position or an upright position, and the operation reliability and the heat exchange effect of the air conditioner can be improved.
In an alternative embodiment, the method may further include: when the outer heat exchanger 1 may include two or more outer sub heat exchangers, at least one of the two or more outer sub heat exchangers is rotated.
For example: referring to the example shown in fig. 7, the outer parallel flow heat exchangers can be further arranged into an upper part and a lower part which are separated, and the two parts of heat exchangers rotate around the respective supporting shafts.
For example: if the heat exchanger is divided into two parts, after the heat exchanger rotates into a horizontal direction, the space occupied by the heat exchanger in the horizontal direction is half of the height dimension of the whole heat exchanger.
For example: as shown in fig. 7, the difference between the present alternative embodiment and the preferred embodiment is that: the outer heat exchanger 1 is divided into an outer upper heat exchanger 12 and an outer lower heat exchanger 11, and the two heat exchangers are respectively provided with an upper driving motor 22 and a lower driving motor 21, and are also respectively provided with parts such as a supporting shaft, a bearing and the like. The two parts of heat exchangers can rotate around the supporting shafts respectively and independently. The heat exchanger is divided into an upper part and a lower part, so that the size of the heat exchanger in the vertical direction is reduced, and the occupied transverse space is small and the structure is more compact when the heat exchanger rotates to a horizontal transverse position.
Therefore, the outside heat exchangers are arranged separately and rotate independently, so that the occupied space in the rotating process can be saved, and the rotating flexibility can be improved.
In an alternative embodiment, the method may further include: when the outside heat exchanger 1 may include two or more outside sub heat exchangers, and/or at least another one of the two or more outside sub heat exchangers is caused to perform the normal heat exchange.
For example: referring to the example shown in fig. 8, the outside parallel flow heat exchanger is provided as separate upper and lower parts, wherein the upper part heat exchanger is maintained in a fixed upright state, the lower part heat exchanger is provided to be rotatable about its support shaft, the space required for rotation is reduced, the structure is more compact, and the support shaft, bearings, driving motor, etc. of the upper part heat exchanger are eliminated, and the structure is simpler and the cost is lower.
For example: as shown in fig. 8, the present alternative embodiment differs from the first alternative embodiment in that: the outer upper heat exchanger 12 is in a fixed non-rotating state, the outer lower heat exchanger 11 is provided with parts such as a lower driving motor 21, a supporting shaft, a bearing and the like, and the outer lower heat exchanger 11 can rotate around the supporting shaft. When the outer heat exchanger 1 heats, the outer heat exchanger serves as an evaporator to absorb heat by evaporation, at the moment, the upper pipe joint is an outlet of the outer heat exchanger 1, and the lower pipe joint is an inlet of the outer heat exchanger 1. Because the refrigerant flows from bottom to top, the lower half of the outer heat exchanger is easier to form condensed water and frost, and therefore after the outer heat exchanger is divided into two parts, the condensed water and frost are formed from the outer lower heat exchanger 11 at first and mainly gathered in the outer lower heat exchanger 11. The condensed water and the defrost water on the outer lower heat exchanger can be discharged only by controlling the outer lower heat exchanger 11 to rotate to an inclined position or a horizontal flat position in the heating mode or the defrosting mode, and the same functions as described in the optimal embodiment are realized. Moreover, the transverse space occupied by the scheme is small, the structure is more compact, the supporting shaft, the bearing, the driving motor and the like of the upper part heat exchanger are eliminated, the structure is simpler, and the cost is lower.
Therefore, the lower part heat exchanger is rotated, the upper part heat exchanger is fixed, the rotating space can be saved, the rotating cost can be saved, and the use convenience and the humanization are good.
