Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The main solution of the invention is: the method comprises the steps that temperature values detected by all temperature detection devices in a current operation mode are obtained, and the temperature detection devices are arranged at refrigerant inlets and refrigerant outlets of at least two heat exchangers of an indoor unit of the air conditioner; comparing the temperature values detected by the temperature detection devices to obtain a first comparison result; and acquiring the installation position information of each temperature detection device according to the first comparison result and the current operation mode.
Since the control logic of the air conditioner is associated with the installation positions of the temperature detection devices arranged at the inlet and the outlet of the indoor heat exchanger, when the temperature detection devices are plugged in error, the control of the air conditioner is failed, and even the air conditioner is damaged. Therefore, in order to avoid errors in the installation positions of the temperature detection devices, the installation positions of the temperature detection devices are usually manually detected and marked at a production end, but the manual detection and marking method is prone to errors in the detection of the installation positions due to manual errors, and is not beneficial to improving the accuracy of the detection of the installation positions of the temperature detection devices. The present invention thus provides the solution described above, aiming at improving the accuracy of the detection of the mounting position of the temperature detection device.

The network interface 1004 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface). The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the air conditioner configuration shown in fig. 1 is not intended to be limiting of the air conditioner and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
In the air conditioner shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call the installation location acquisition program of the temperature detection device stored in the memory 1005 and execute the following steps associated with the respective embodiments of the installation location acquisition method of the temperature detection device.
Based on the hardware architecture of the air conditioner, embodiments of the method for acquiring the installation position of the temperature detection device according to the present invention are provided, and optionally, a system structure of the air conditioner according to the embodiments is as shown in fig. 2.
The air conditioner includes an outdoor unit 10 and at least one indoor unit 20. The outdoor unit 10 comprises a compressor 11, a four-way valve 12 and an outdoor heat exchanger 13, and each indoor unit 20 comprises a first heat exchanger 21, a second heat exchanger 22, a first throttling device 23 and a second throttling device 24; four interfaces of the four-way valve 12 are respectively connected with an exhaust port of the compressor 11, the outdoor heat exchanger 13, the second heat exchanger 22 and a return air port of the compressor 11, a first interface of the first heat exchanger 21 is connected with the exhaust port of the compressor 11, a second interface of the first heat exchanger 21 passes through the first throttling device 23 and then is connected between the second heat exchanger 22 and the outdoor heat exchanger 13, a first interface of the second heat exchanger 22 is connected with the four-way valve 12, and a second interface of the second heat exchanger 22 passes through the second throttling device 24 and then is connected with the outdoor heat exchanger 13. The outdoor unit further includes a gas-liquid separator, and the discharge port of the compressor 11 is connected to the gas-liquid separator.
Based on the above structure, when the air conditioner of this embodiment operates the refrigeration mode, the refrigeration principle of air conditioner is: after being discharged from the exhaust port of the compressor 11, the high-temperature and high-pressure refrigerant flows to the outdoor heat exchanger 13 through the four-way valve 12, after condensing and heat exchanging in the outdoor heat exchanger 13, the refrigerant flows into the second heat exchanger 22 through the second throttling device 24, and after evaporating and heat exchanging in the second heat exchanger 22, the refrigerant flows back to the compressor 11 through the four-way valve 12. It can be understood that, in the air conditioner of this embodiment, when the air conditioner operates in the cooling mode, the first throttling device 23 on the first heat exchanger 21 is in the closed state, and the heat exchange refrigerant is not present in the first heat exchanger 21.
Based on the above structure, when the air conditioner of this embodiment operates in the dehumidification reheating mode, the dehumidification heating principle of the air conditioner is as follows: after the high-temperature and high-pressure refrigerant is discharged from the exhaust port of the compressor 11, part of the refrigerant flows to the outdoor heat exchanger 13 through the four-way valve 12, after heat exchange of a refrigerant in the outdoor heat exchanger 13, the refrigerant flows into the second heat exchanger 22 through the second throttling device 24, after evaporation and heat exchange of the second heat exchanger 22, the refrigerant flows back to the compressor 11 through the four-way valve 12, a refrigeration and dehumidification loop is formed, and indoor air is dehumidified. Part of the refrigerant discharged from the compressor 11 directly flows to the first heat exchanger 21 from a pipeline connecting the compressor 11 and the first heat exchanger 21, and after condensing and heat exchanging in the first heat exchanger 21, the high-temperature and high-pressure refrigerant flows to the second heat exchanger 22 through the first throttling device 23, joins with the refrigerant flowing in the outdoor heat exchanger 13, evaporates and exchanges heat in the second heat exchanger 22, and then flows back to the compressor 11 through the four-way valve 12, so as to form a heating circulation loop. Optionally, the circulation circuit of the first heat exchanger 21 and the circulation circuit of the second indoor unit 20 operate simultaneously, so as to form the dehumidification and reheating mode.
It is understood that the dehumidification and reheat mode means that the air after the cooling and dehumidification is heated by the first heat exchanger 21 and then discharged to the indoor. As described above, the first heat exchanger 21 and the second heat exchanger 22 are disposed in each indoor unit 20, and the first heat exchanger 21 is located between the second heat exchanger 22 and the air outlet of the air conditioner, so that after the second heat exchanger 22 absorbs moisture in the air, and before the air is blown to the air outlet, the first heat exchanger 21 heats the air, and the air temperature is increased, so that the temperature of the air at the air outlet is higher.
The air conditioner provided in this embodiment includes a first heat exchanger 21 and a second heat exchanger 22, and correspondingly, temperature detection devices need to be respectively disposed at outlets and inlets of the first heat exchanger 21 and the second heat exchanger 22 to detect temperatures at refrigerant inlets and at refrigerant outlets of the first heat exchanger 21 and the second heat exchanger 22. At this time, since the control logic of the air conditioner is related to the temperatures at the refrigerant inlets and the temperatures at the refrigerant outlets of the first heat exchanger 21 and the second heat exchanger 22, if one of the temperature detection devices is installed at a wrong position, the control of the air conditioner may be disabled, and even the air conditioner may be damaged. In order to avoid errors in the installation position of the temperature detection device, the production end usually performs manual distinguishing and marking, and the marking errors are easily caused by manual errors. Thus, the accuracy of the mounting position detection of the temperature detection device is yet to be further improved.
Based on the structural features of the air conditioner, a first embodiment of the method for acquiring the installation position of the temperature detection device of the present invention is provided. Referring to fig. 3, in this embodiment, the method for acquiring the installation position of the temperature detection device includes the following steps:
step S10: the method comprises the steps that temperature values detected by all temperature detection devices in a current operation mode are obtained, and the temperature detection devices are arranged at refrigerant inlets and refrigerant outlets of at least two heat exchangers of an indoor unit of the air conditioner;
step S20: comparing the temperature values detected by the temperature detection devices to obtain a first comparison result;
step S30: and acquiring the installation position information of each temperature detection device according to the first comparison result and the current operation mode.
It should be noted that temperature detection devices are installed at the refrigerant inlet and the refrigerant outlet of the heat exchanger of the outdoor unit 20, and are used for detecting the temperature value at the inlet and the temperature value at the outlet of each heat exchanger of the outdoor unit 20 of the air conditioner, so as to reasonably control each heat exchanger. The number of indoor heat exchangers differs for different types of outdoor units 20. The air conditioner in the present embodiment is particularly an air conditioner having two indoor heat exchangers. For example, an air conditioner capable of operating in a dehumidification and reheat mode generally requires at least two indoor heat exchangers, at least one of which is used for cooling and dehumidifying and at least one of which is used for heating air after cooling and dehumidifying and discharging the heated air to the indoor space, so as to reduce the risk of condensation and prevent cold wind from blowing people. Alternatively, the operation mode of the air conditioner may include: a cooling mode, a heating mode, a dehumidification and reheating mode, and the like. The above operation modes may be separately operated for the conventional air conditioner, and different operation modes may be simultaneously operated for the different indoor units for the multi-split air conditioner.
In different operation modes, the temperature values at the refrigerant inlets and the temperature values at the refrigerant outlets of different heat exchangers are different, and the temperature values at the refrigerant inlets and the temperature values at the refrigerant outlets of the same heat exchanger can also exhibit different variation characteristics under different operation parameters (in this embodiment, especially, the opening degrees of the first throttling device 23 and the second throttling device 24). For example, in the cooling mode, the temperature value at the refrigerant inlet of the heat exchanger is lower than the temperature value at the refrigerant outlet; under the mode of heating, the temperature value of the refrigerant entrance of heat exchanger is higher than the temperature value of refrigerant exit, so, no matter air conditioner operation refrigeration mode or the mode of heating, can distinguish which temperature-detecting device is located the refrigerant entrance of heat exchanger, which temperature-detecting device is located the refrigerant exit of heat exchanger. And, the heat transfer area of different heat exchangers is different, and throttling arrangement such as accessible electronic expansion valve adjusts the refrigerant volume that gets into the heat exchanger to make different heat exchangers correspond and present different degrees of superheat, in order to distinguish which temperature-detecting device is located the heat exchanger that heat transfer area is big, which temperature-detecting device is located the heat exchanger that heat transfer area is less. Therefore, the installation positions of the temperature detection devices can be distinguished according to the temperature values detected by the temperature detection devices in different operation modes, and manual distinguishing and marking are not needed.
Specifically, based on the temperature variation characteristics of the refrigerant inlet and outlet of each heat exchanger in different operation modes, after the air conditioner acquires the temperature values detected by each temperature detection device, in order to distinguish the installation positions of each temperature detection device, the acquired temperature values may be compared to obtain a first comparison result, so as to determine the actual installation position of each temperature detection device according to the first comparison result in combination with the current operation mode of the air conditioner. For example, in the cooling mode, the lowest two temperature values may be found to determine the temperature detection device located at the refrigerant inlet of each heat exchanger, and the highest two temperature values may be found to determine the temperature detection device located at the refrigerant outlet of each heat exchanger; then, the superheat degree of different heat exchangers is changed by adjusting the throttling device at the refrigerant inlet of at least one heat exchanger, so that the temperature detection devices corresponding to the different heat exchangers can be determined from the temperature detection devices at the refrigerant inlet, and the temperature detection devices corresponding to the different heat exchangers can be determined from the temperature detection devices at the refrigerant outlet. Similarly, in the heating mode, the lowest two temperature values can be found first to determine the temperature detection device located at the refrigerant outlet of each heat exchanger, and the highest two temperature values can be found to determine the temperature detection device located at the refrigerant inlet of each heat exchanger; then the opening degree of a throttling device at a refrigerant inlet of at least one heat exchanger is adjusted, so that different heat exchangers generate different degrees of superheat, and the installation positions of the temperature detection devices can be distinguished according to different degrees of superheat. Therefore, no matter the production end is debugged, the client end is started for the first time to check, or the client end is rechecked after maintenance, no human intervention is needed.
After the installation positions of the temperature detection devices are obtained, the installation positions of the temperature detection devices and the identification information of the temperature detection devices can be associated, and the associated installation positions and identification information are stored for subsequent rechecking.
In this embodiment, the installation positions of the temperature detection devices can be determined according to the comparison result of the temperature values detected by the temperature detection devices and the current operation mode, manual marking and distinguishing are not needed, and the situation that the control logic of the air conditioner is invalid or even the air conditioner is damaged due to plugging error of the temperature detection devices caused by manual error can be avoided. Therefore, the accuracy of the detection of the installation position of the temperature detection device is improved, and the damage to the air conditioner is reduced.
Based on the above embodiment, a second embodiment of the installation position acquisition method of the temperature detection device of the present invention is proposed. Referring to fig. 4, in the present embodiment, step S30 includes:
step S31: determining a first temperature detection device positioned at the refrigerant inlets of the first heat exchanger and the second heat exchanger in the current mode and a second temperature detection device positioned at the refrigerant outlets of the first heat exchanger and the second heat exchanger in the current mode according to the first comparison result;
step S32: adjusting the opening degree of at least one of the first throttling device and the second throttling device to enable the opening degree adjusting modes of the first throttling device and the second throttling device to be different;
step S33: after a preset time interval, comparing the temperatures detected by the two first temperature detection devices to obtain a second comparison result, and determining a first temperature detection device corresponding to a refrigerant inlet of the first heat exchanger and a first temperature detection device corresponding to a refrigerant inlet of the second heat exchanger according to the second comparison result;
step S34: and comparing the temperatures detected by the two second temperature detection devices to obtain a second comparison result, and determining a second temperature detection device corresponding to the refrigerant outlet of the first heat exchanger and a second temperature detection device corresponding to the refrigerant outlet of the second heat exchanger according to the second comparison result.
It should be noted that, the air conditioner in the embodiment is especially an air conditioner having at least two heat exchangers, for example, an air conditioner having a dehumidification and reheat function, the air conditioner is at least provided with a first heat exchanger 21 and a second heat exchanger 22, and the outlets and inlets of the first heat exchanger 21 and the second heat exchanger 22 are respectively provided with a temperature detection device, so that four temperature values can be obtained through corresponding detection. Since the performance of the air conditioner is usually debugged in the cooling mode and the heating mode when the production end debugges the air conditioner, the cooling mode and the heating mode are mainly explained in the present embodiment. In the debugging phase, the air conditioner may determine, according to the outdoor environment temperature, which operation mode the outdoor unit 20 operates in, and then feed back the mode identification information corresponding to the operation mode to the outdoor unit 20, so that the outdoor unit 20 may operate according to the operation mode according to the mode identification information. Optionally, when the outdoor environment temperature is greater than or equal to 20 ℃, setting the target temperature of the internal machine to be 16 ℃ for running a refrigeration mode; and when the outdoor environment temperature is less than 20 ℃, setting the target temperature of the internal machine to be 30 ℃ for heating operation.
In order to effectively distinguish the installation positions of the temperature detection devices, a first temperature detection device located at the refrigerant inlet of the first heat exchanger 21 and the second heat exchanger 22 and a second temperature detection device located at the refrigerant outlet of the first heat exchanger 21 and the second heat exchanger 22 in the current operation mode may be determined according to the first comparison result.
Optionally, the first temperature detection device and the second temperature detection device corresponding to different operation modes have different determination manners. When the current operation mode is the cooling mode, the first throttling device 23 may be operated at an opening a, and the second throttling device 24 may be operated at an opening b, to obtain a first comparison result. At this time, the temperature detection devices corresponding to the two minimum temperature values can be determined as the first temperature detection devices located at the refrigerant inlets of the first heat exchanger 21 and the second heat exchanger 22 according to the first comparison result; and the temperature detection devices corresponding to the two maximum temperature values are determined as the second temperature detection devices located at the refrigerant outlets of the first heat exchanger 21 and the second heat exchanger 22. Wherein, the value range of a can be 70 steps to 150 steps, and the preferred value range in this embodiment is 90 steps; the value range of b can be 20 steps to 90 steps, and preferably 40 steps in the embodiment. When the current operation mode is the heating mode, the first throttle 23 may be operated at an opening c, and the second throttle 24 may be operated at an opening d, to obtain a first comparison result. At this time, the temperature detection devices corresponding to the two maximum temperature values can be determined as the first temperature detection devices located at the refrigerant inlets of the first heat exchanger 21 and the second heat exchanger 22 according to the first comparison result; then, the temperature detection device corresponding to the two smallest temperature values can be determined as the second temperature detection device located at the refrigerant outlets of the first heat exchanger 21 and the second heat exchanger 22 based on the first comparison result. Both the opening c and the opening d are preferably 480 steps.
Then, the opening degree of at least one of the first throttling device 23 and the second throttling device 24 may be adjusted so that the opening degree adjustment manners of the first throttling device 23 and the second throttling device 24 are different, so that the first heat exchanger 21 and the second heat exchanger 22 have different degrees of superheat, and the temperature detection device located at the refrigerant inlet of the first heat exchanger 21 and the temperature detection device located at the refrigerant inlet of the second heat exchanger 22 may be determined from the determined first temperature detection device; and a temperature detection device located at the refrigerant outlet of the first heat exchanger 21 and a temperature detection device located at the refrigerant outlet of the second heat exchanger 22 are determined from the determined second temperature detection devices. Therefore, the installation positions of the four temperature detection devices can be distinguished.
Alternatively, in order to make the first heat exchanger 21 and the second heat exchanger 22 have different degrees of superheat so as to effectively distinguish the temperature detection devices corresponding to the different heat exchangers, the opening degree of the first throttling device 23 and/or the second throttling device 24 may be adjusted by: when the current operation mode is the cooling mode, the opening degree of the first throttle device 23 is increased, and the opening degree of the second throttle device 24 is decreased. Therefore, since the heat exchange area of the first heat exchanger 21 is larger than that of the second heat exchanger 22, after the opening degree of the first throttling device 23 is increased, the flow rate of the refrigerant flowing through the first heat exchanger 21 is also larger, and the temperature of the refrigerant can be rapidly heated to a higher temperature, so that the temperature of the flow rate of the refrigerant flowing from the rear part is not so high, so that the superheat degree of the first heat exchanger 21 is reduced, that is, the superheat degree of the first heat exchanger 21 is smaller than that of the second heat exchanger 22. When the current operation mode is the heating mode, the opening degree of the first throttle device 23 is decreased. In this way, since the heat exchange area of the first heat exchanger 21 is larger than that of the second heat exchanger 22, after the opening degree of the first throttling device 23 is reduced, the temperature of the refrigerant can be reduced after the refrigerant flows through the first heat exchanger 21.
After the opening degree of the first throttling device 23 and/or the second throttling device 24 is adjusted and a time interval is preset, the temperature values detected by the two first temperature detection devices are compared to obtain a second comparison result. On the one hand, the first temperature detection device at the refrigerant inlet of the first heat exchanger 21 and the first temperature detection device at the refrigerant inlet of the second heat exchanger 22 may be determined according to the second comparison result. On the other hand, the second temperature detection device at the refrigerant outlet of the first heat exchanger 21 and the second temperature detection device at the refrigerant outlet of the second heat exchanger 22 may be determined based on the second comparison result. Therefore, the installation positions of the temperature detection devices can be accurately distinguished according to the second comparison result.
Specifically, when the current operation mode is the cooling mode, the superheat degree of the first heat exchanger 21 is less than the superheat degree of the second heat exchanger 22, so that the temperature at the refrigerant inlet of the second heat exchanger 22 is the highest, and the temperature at the refrigerant outlet of the first heat exchanger 21 is the lowest. Thus, it can be determined according to the second comparison result that the first temperature detection device with the lower temperature of the two first temperature detection devices is located at the refrigerant inlet of the first heat exchanger 21, and the first temperature detection device with the higher temperature is located at the refrigerant inlet of the second heat exchanger 22; in addition, it can be determined according to the second comparison result that the second temperature detection device with the lower temperature of the two second temperature detection devices is located at the refrigerant outlet of the first heat exchanger 21, and the first temperature detection device with the higher temperature is located at the refrigerant outlet of the second heat exchanger 22. When the current operation mode is the heating mode, the refrigerant temperature is decreased to be lower due to the decrease of the opening degree of the first throttling device 23, so that the temperature at the refrigerant inlet of the second heat exchanger 22 is the highest, and the temperature at the refrigerant outlet of the first heat exchanger 21 is the lowest. Thus, it can be determined according to the second comparison result that the first temperature detection device with the lower temperature of the two first temperature detection devices is located at the refrigerant inlet of the first heat exchanger 21, and the first temperature detection device with the higher temperature is located at the refrigerant inlet of the second heat exchanger 22; in addition, it can be determined according to the second comparison result that the second temperature detection device with the lower temperature of the two second temperature detection devices is located at the refrigerant outlet of the first heat exchanger 21, and the first temperature detection device with the higher temperature is located at the refrigerant outlet of the second heat exchanger 22.
In this embodiment, after determining the first temperature detection device located at the refrigerant inlet of the first heat exchanger 21 and the second heat exchanger 22 and the second temperature detection device located at the refrigerant outlet of the first heat exchanger 21 and the second heat exchanger 22 in the current operation mode according to the first comparison result, by adjusting the opening degree of at least one of the first throttling device 23 and the second throttling device 24, the temperature detection device located at the refrigerant inlet of the first heat exchanger 21, the temperature detection device located at the refrigerant inlet of the second heat exchanger 22, the temperature detection device located at the refrigerant outlet of the first heat exchanger 21 and the temperature detection device located at the refrigerant outlet of the second heat exchanger 22 can be effectively distinguished according to the second comparison result, and human distinguishing and marking are not required, so that the accuracy of detecting the installation position of the temperature detection device can be improved.
Based on the above embodiments, a third embodiment of the installation position acquisition method of the temperature detection device of the present invention is proposed. Referring to fig. 5, in this embodiment, the method for acquiring the installation position of the temperature detection device further includes:
step S01: when the indoor unit is started or started after power failure, judging whether debugging is needed or not;
step S02: when the rechecking identification information is not detected, operating a dehumidification reheating mode, and acquiring temperature values detected by the temperature detection devices;
step S03: acquiring target position information of each temperature detection device according to the temperature value;
step S04: and when the target position information is consistent with the stored installation position information, adding rechecking identification information, wherein the installation position information is stored after the installation position information of each temperature detection device is obtained according to the first comparison result and the current operation mode.
When the indoor unit is started, debugging may be required to reacquire the installation position information of each temperature detection device, and the installation positions of the temperature detection devices may also need to be rechecked, so as to avoid that the installation positions of the temperature detection devices are mistaken, which causes damage to the air conditioner or control failure of the air conditioner and affects user experience. Therefore, when the indoor unit is started or started after power failure, whether debugging is needed or not can be judged firstly. If the debugging is needed, go to step S10; if the debugging is not needed, the installation positions of the temperature detection devices are rechecked to determine the accuracy of the installation positions of the temperature detection devices when the rechecking condition is met. Optionally, the manner of determining whether debugging is needed may be: detecting whether a debugging instruction sent by a user in a voice or key pressing mode is received or not, and considering that debugging is needed when the debugging instruction is detected; or, detecting whether the air conditioner is started for the first time, and if the air conditioner is started for the first time, determining that debugging is needed; alternatively, it is detected whether or not there is previously stored mounting position information of each temperature detection device, and if not, it is determined that debugging is necessary. Alternatively, the rechecking condition may be: the pre-stored installation position information is detected, but the rechecking identification information and/or the refrigerant abnormal information and the like are not detected, so that the accuracy of debugging and rechecking can be influenced when the refrigerant is insufficient.
When the rechecking identification information is not detected, the dehumidification reheating mode can be operated to recheck the installation positions of the temperature detection devices. Specifically, temperature values detected by the respective temperature detection devices in the dehumidification reheating mode may be acquired, and the acquired respective temperature values may be compared to acquire target position information of the respective temperature detection devices. Since the installation position information of each temperature detection device exists after the installation position of each temperature detection device is acquired according to the first comparison result and the current operation mode, the target position information can be compared with the installation position information stored in advance. If the comparison result is consistent with the comparison result, the rechecking is considered to be successful, namely the installation position of each temperature detection device is correct. At this time, in order to avoid the electric energy consumption and the influence on the user experience caused by entering the rechecking logic when the computer is normally started next time, after the rechecking is successful, rechecking identification information can be generated and stored. Therefore, when the computer is started next time, if the rechecking identification information is detected, the rechecking cannot be repeated.
Optionally, after the temperature values detected by the temperature detection devices in the dehumidification reheating mode are obtained, the obtained temperature values may be compared to obtain a fourth comparison result. Since a part of the refrigerant compressed by the compressor at high temperature and high pressure passes through the outdoor heat exchanger and then enters the first heat exchanger 21, and a part of the refrigerant does not pass through the outdoor heat exchanger and enters the second heat exchanger 22, the temperature of the refrigerant inlet and outlet of the second heat exchanger 22 is higher than that of the refrigerant inlet and outlet of the second heat exchanger 22. Thus, two temperature detection devices located at the refrigerant inlet and the refrigerant outlet of the first heat exchanger 21 and two temperature detection devices located at the refrigerant inlet and the refrigerant outlet of the second heat exchanger 22 can be distinguished according to the fourth comparison result. Specifically, it can be determined according to the fourth comparison result that the temperature detection devices corresponding to the two maximum temperature values are located at the refrigerant inlet and the refrigerant outlet of the second heat exchanger 22, and the temperature detection devices corresponding to the two minimum temperature values are located at the refrigerant inlet and the refrigerant outlet of the first heat exchanger 21.
In order to further distinguish the temperature detection device positioned at the refrigerant inlet of the first heat exchanger 21 and the temperature detection device positioned at the refrigerant outlet of the first heat exchanger 21 from the two temperature detection devices positioned at the refrigerant inlet and the refrigerant outlet of the first heat exchanger 21, and distinguish the temperature detection device positioned at the refrigerant inlet of the second heat exchanger 22 and the temperature detection device positioned at the refrigerant outlet of the second heat exchanger 22 from the two temperature detection devices positioned at the refrigerant inlet and the refrigerant outlet of the second heat exchanger 22, the temperature difference between the refrigerant inlet and the refrigerant outlet can be presented by increasing the opening degree of the first throttling device 23 and/or reducing the opening degree of the second throttling device 24, so as to distinguish the temperature detection devices of the refrigerant inlet and the refrigerant outlet. At this time, after a preset time interval, the temperature values detected by the temperature detection devices may be compared to obtain a fifth comparison result, so as to distinguish the installation positions of the temperature detection devices according to the fifth comparison result. Specifically, after the opening degree of the first throttling device 23 is increased, the temperature at the refrigerant inlet of each heat exchanger is higher than the temperature at the refrigerant outlet, so that the temperature detection device corresponding to the larger temperature value of the two maximum temperature values can be determined to be located at the refrigerant inlet of the second heat exchanger 22 according to the fifth comparison result, and the temperature detection device corresponding to the smaller temperature value is located at the refrigerant outlet of the second heat exchanger 22; moreover, it can be determined according to the fifth comparison result that the temperature detection device corresponding to the larger temperature value of the two minimum temperature values is located at the refrigerant inlet of the first heat exchanger 21, and the temperature detection device corresponding to the smaller temperature value is located at the refrigerant outlet of the first heat exchanger 21. Thus, the target position information of each temperature detection device can be obtained.
If the rechecking fails, the mounting position of each temperature detection device is incorrect. At this time, the system can be automatically turned off, so that the user can replace the installation positions of the temperature detection devices, and then when the outdoor unit 20 is turned on again, the installation positions of the temperature detection devices are rechecked again according to the current operation mode, so as to ensure that the temperature detection devices are installed correctly and then used. Optionally, before the automatic shutdown, prompt information of the installation positions of the temperature detection devices may be output to avoid repeated replacement of the installation positions of the temperature detection devices.
This embodiment is through when satisfying the recheck condition, and the mounted position of operation dehumidification reheat mode to each temperature-detecting device rechecks, and when can avoiding each temperature-detecting device's mounted position incorrect, the operation air conditioner leads to the control of air conditioner to become invalid or causes the damage to the air conditioner.
