A conventional refrigeration system, such as a refrigerator, generally forms a refrigeration circuit that sequentially flows through a compressor, a condenser, a refrigeration evaporator, a freezing evaporator, and a compressor. When refrigeration is requested, the refrigerant in the condenser is in a high-temperature high-pressure state, and the refrigerant in the evaporator is in a low-temperature low-pressure state; when refrigeration is not required, the refrigerant in the condenser flows to the refrigerating chamber evaporator and the freezing chamber evaporator, and the temperature of the refrigerant entering the freezing chamber evaporator is higher than the refrigeration temperature of the freezing chamber due to no regenerative action, so that the temperature of the freezing chamber is increased; at the same time, the pressure in the condenser is reduced and the liquid refrigerant in the condenser may re-evaporate absorbing heat from the environment, increasing the heat load on the refrigerator. And after restarting, the system needs to reestablish the pressure difference between the condenser and the evaporator, resulting in increased energy consumption of the refrigerator.
In view of the above, the present invention provides a refrigeration system for use in a refrigeration appliance, such as a refrigerator, freezer, air conditioner, or the like. For convenience of understanding, the refrigeration device is taken as a refrigerator as an example for explanation. Referring to fig. 1 to 2, an embodiment of a refrigeration system applied to a refrigerator according to the present invention is shown in the drawings.
In the following embodiments, the term "a" or "an" means two or more.
Referring to fig. 1 to 2, the refrigeration system 1 provided by the present invention includes a compressor 100, a condenser 200, a first evaporator 310, a second evaporator 320, and a first switching component 400, which are sequentially connected through a pipeline structure 10a to form a refrigeration circuit 10, wherein a refrigeration temperature of the first evaporator 310 is not less than a refrigeration temperature of the second evaporator 320, and the first switching component 400 is configured to control on/off between the condenser 200 and the first evaporator 310; the refrigeration system 1 further includes a flow blocking structure 500 disposed in the refrigeration circuit 10, where the flow blocking structure 500 is disposed between the first evaporator 310 and the second evaporator 320, so as to block the refrigerant flowing out of the first evaporator 310 from flowing into the second evaporator 320 when the compressor 100 is turned off and the first switching part 400 is communicated with a flow path between the condenser 200 and the first evaporator 310.
In the technical solution provided by the present invention, the first switching component 400 cuts off the flow path between the condenser 200 and the first evaporator 310 when the compressor 100 is shut down, which is helpful for maintaining the pressure at the condenser 200 and preventing the refrigerant from absorbing heat in the environment again due to the pressure reduction at the condenser 200; the energy consumption required when the pressure difference between the two sides is formed in the restarting process of the compressor 100 can be reduced, and the purpose of energy conservation is achieved; when the refrigeration system 1 enters the next operation cycle, the first switching component 400 leads the flow path between the condenser 200 and the first evaporator 310 before the compressor 100 is restarted, so that the refrigerant after being stopped and cooled in the condenser 200 enters the first evaporator 310 and then pre-cools the first evaporator 310, which is beneficial to improving the initial refrigeration effect of the first evaporator 310 and reducing the energy consumption of the first evaporator 310; the flow blocking structure 500 cuts off a flow path between the first evaporator 310 and the second evaporator 320, and blocks the refrigerant at the condenser 200 from flowing into the second evaporator 320, thereby preventing the temperature of the compartment in which the second evaporator 320 is located from increasing, and reducing the energy consumption of the second evaporator 320.
It will be understood that, taking the example of the application of the refrigeration system 1 in a refrigerator, which is a multi-system refrigerator, the refrigeration circuit 10 is provided with a plurality of evaporators. For example, when the compartments provided in the refrigerator are at least two of a refrigerating compartment, a freezing compartment and a temperature-changing compartment, the corresponding evaporators are at least two of a refrigerating compartment evaporator, a freezing compartment evaporator and a temperature-changing evaporator.
The refrigerating temperatures of the refrigerating chamber evaporator, the freezing chamber evaporator and the variable temperature evaporator are different due to different refrigerating temperatures required by the refrigerating chamber, the freezing chamber and the variable temperature chamber. Therefore, in the present embodiment, the plurality of evaporators includes a first evaporator 310 and a second evaporator 320, and the cooling temperature of the first evaporator 310 is higher than the cooling temperature of the second evaporator 320. That is, the first evaporator 310 corresponds to a refrigerating compartment evaporator, and the second evaporator 320 corresponds to a freezing compartment evaporator.
When the refrigeration system 1 is applied to different types of the refrigeration devices, the first evaporator 310 and the second evaporator 320 may be connected in series, in parallel, or in semi-series/parallel, etc. as appropriate. The first evaporator 310 and the second evaporator 320 may be provided in the same type or in different types. The first evaporator 310 and the second evaporator 320 may be any suitable type of evaporator, including, for example, one or more of a tube and fin heat exchanger, a microchannel heat exchanger, a flat tube heat exchanger, a shell and tube heat exchanger, a plate heat exchanger, and the like. Specifically, in an embodiment, the tube and fin heat exchanger and the microchannel heat exchanger may be connected in series/in parallel to serve as the first evaporator 310 or the second evaporator 320.
It should be noted that the above components do not limit the composition of the refrigeration system 1, and other components may also be arranged in series or in parallel on the refrigeration circuit 10 according to actual needs; furthermore, the refrigeration system 1 may further be connected with a bypass or a branch at any suitable position of the refrigeration circuit 10, which is not described herein.
In an embodiment, the refrigeration system 1 further comprises a throttling member disposed between the condenser 200 and the first evaporator 310. The throttling part is capable of reducing the pressure and temperature of the refrigerant flowing out through the condenser 200 using a throttling effect and controlling the flow rate and the superheat/coldness of the refrigerant in the refrigeration circuit 10. The specific expression of the throttling component is not limited, and may be set according to the actual requirement of the refrigeration system 1. Generally, the throttling components include capillary tubes, electronic expansion valves, throttling horns, and throttling valves such as manual expansion valves, float ball regulating valves, and thermostatic expansion valves. Since the capillary tube is widely used in refrigeration equipment such as a refrigerator, the throttle member will be described as an example of the capillary tube in the following embodiments.
The throttling parameters of different throttling parts are different accordingly. For example, when the throttling component is set as a capillary tube in the present embodiment, the throttling parameter of the capillary tube may be a tube diameter, a tube length, a number, and the like.
In an embodiment, the refrigeration system 1 further comprises a dry filter 700, and the dry filter 700 is disposed between the throttling component and the condenser 200. The drying filter 700 can filter and dehumidify the refrigerant passing through, and effectively reduces the hidden troubles of ice blockage and the like of the refrigeration circuit 10. The specific representation form of the filter-drier 700 is not limited by the design, and the specification of the filter-drier 700 may be adjusted according to the actual requirement of the refrigeration system 1, where the specification of the filter-drier 700 includes the inner diameter, the outer diameter and other dimensions, and the types of internal devices such as a filter bowl, a mesh cloth, a molecular sieve and the like.
Based on the refrigeration circuit 10, the compressor 100 compresses the gaseous refrigerant into a high-temperature high-pressure gaseous state, and sends the gaseous refrigerant to the condenser 200 for cooling, the gaseous refrigerant is cooled by the condenser 200 and then becomes a medium-temperature high-pressure liquid refrigerant, the medium-temperature liquid refrigerant enters the drying filter 700 for filtering and dehumidification, the medium-temperature liquid refrigerant is throttled and depressurized by the throttling component, a large amount of low-temperature low-pressure gas-liquid mixture liquid is formed, the liquid is vaporized by absorbing heat in air by the first evaporator 310/the second evaporator 320, the gaseous refrigerant is finally returned to the compressor 100 for continuous compression, and the refrigeration is continuously performed in a circulating manner.
The first switching member 400 is configured to control on/off of a flow path between the condenser 200 and the first evaporator 310 and/or to control on/off of a flow path between the condenser 200 and the second evaporator 320. It is to be understood that, when the first evaporator 310 and the second evaporator 320 are connected in series, the first switching member 400 is an on-off valve, and when the on-off valve is opened, a flow path between the condenser 200 and the first evaporator 310 is conducted; when the on-off valve is closed, the flow path between the condenser 200 and the first evaporator 310 is cut off. When the first evaporator 310 and the second evaporator 320 are connected in parallel, the first switching component 400 may be configured as a direction switching valve, and the direction switching valve is disposed at the same input end of the branch where the first evaporator 310 is located and the branch where the second evaporator 320 is located, and can switch the refrigerant flowing out of the condenser 200 to flow to the first evaporator 310 and/or the second evaporator 320.
The flow blocking structure 500 is disposed on a flow path between the first evaporator 310 and the second evaporator 320. It can be understood that when the compressor 100 is turned off, the first switching member 400 cuts off the flow path between the condenser 200 and the first evaporator 310, and prevents a portion of the high-temperature and high-pressure refrigerant still remaining in the condenser 200 from directly entering the first evaporator 310. When the refrigeration system 1 needs to start the next operation cycle, before the charge compressor 100, the first switching component 400 is controlled to communicate with the flow path between the condenser 200 and the first evaporator 310, so that the refrigerant which is properly cooled in the condenser 200 in the shutdown process is filtered and dehumidified by the drying filter 700, throttled and reduced in pressure by the throttling component, and then enters the first evaporator 310, the first evaporator 310 can be properly cooled, the compartment where the first evaporator 310 is located is pre-cooled, and the initial refrigeration speed of the first evaporator 310 is increased; at this time, when a portion of the refrigerant flows out of the first evaporator 310, and the temperature of the refrigerant is higher than the cooling temperature of the second evaporator 320, the flow blocking structure 500 can limit the refrigerant from entering the second evaporator 320, and the refrigerant is prevented from increasing the temperature at the second evaporator 320, which results in an increase in energy consumption of the second evaporator 320.
Specifically, referring to fig. 1, in an embodiment, the flow blocking structure 500 includes a transfer portion 510, where the transfer portion 510 is configured to transfer the refrigerant flowing out of the first evaporator 310 to a position other than the second evaporator 320, specifically, the transfer portion 510 has an input end into which the refrigerant enters and an output end from which the refrigerant flows out, the input end of the transfer portion 510 is connected between the first evaporator 310 and the second evaporator 320, and the output end of the transfer portion 510 is connected to the output end of the second evaporator 320. In this way, the refrigerant flowing out of the first evaporator 310 can bypass the second evaporator 320 and be transferred to the output end of the second evaporator 320, and the refrigerant is prevented from entering the second evaporator 320.
The output end of the second evaporator 320 may be a flow path between the second evaporator 320 and the compressor 100 (for example, a first target position), a flow path between the compressor 100 and the condenser 200 (for example, a second target position), or a flow path between the condenser 200 and the first evaporator 310 (for example, a third target position), without limitation.
In a further aspect, a switching member, such as a multi-way reversing valve, may be disposed at an output end of the diverting portion 510, such that the output end of the diverting portion 510 is controlled to be selectively connected to any one of the first target position, the second target position and the third target position according to an operation parameter of the refrigeration circuit 10, such as a temperature, a pressure and the like, such that the diverting position of the refrigerant is adjustable.
The transfer portion 510 is, for example, a suction mechanism that sucks the refrigerant flowing out of the first evaporator 310 to any one of the first target position, the second target position, and the third target position.
Alternatively, referring to fig. 1, in an embodiment, the transfer portion 510 includes a connecting branch 511 and a second switching component 512, wherein an input end of the connecting branch 511 is connected between the first evaporator 310 and the second evaporator 320, and an output end of the connecting branch 511 is connected between the second evaporator 320 and the compressor 100; the second switching component 512 is used for controlling the on/off of the connection branch 511. This helps to simplify the structure of the transfer section 510 and reduce the cost of the refrigeration system 1.
Specifically, the second switching member 512 may be provided as one, for example, a multi-way reversing valve, which is provided at a connection portion between the first evaporator 310, the connecting branch 511 and the second evaporator 320 and is capable of switching the flow of the refrigerant flowing out of the first evaporator 310 to the connecting branch 511 or the second evaporator 320. Alternatively, the second switching member 512 may be provided in plurality. For example, the second switching member 512 is a switching valve respectively disposed on the output flow path of the first evaporator 310, the input flow path of the second evaporator 320, and the connecting branch 511, and when the two switching valves on the output flow path of the first evaporator 310 and the input flow path of the second evaporator 320 are simultaneously opened and the switching valve on the connecting branch 511 is closed, the first evaporator 310 communicates with the second evaporator 320; when the two switching valves on the output flow path of the first evaporator 310 and the connection branch 511 are simultaneously opened and the switching valve on the input flow path of the second evaporator 320 is closed, the first evaporator 310 communicates with the connection branch 511.
In another embodiment, the flow-blocking structure 500 includes a reservoir 520, the reservoir 520 being coupled between the first evaporator 310 and the second evaporator 320. The accumulator 520 can store a certain amount of the refrigerant, and prevent the refrigerant from flowing into the second evaporator 320.
It is understood that when the refrigerant stored in the accumulator 520 has a relatively small volume, a sufficient flow force is generated between the first evaporator 310 and the second evaporator 320 under the normal operation of the refrigeration system 1, and the flow force can bring the refrigerant stored in the accumulator 520 out and into the second evaporator 320. Of course, when the refrigerant capacity stored in the accumulator 520 is relatively large, the refrigeration system 1 may further include a bypass at the accumulator 520, and the bypass is used to discharge or divert more refrigerant stored in the accumulator 520 to another location.
In other embodiments, the flow blocking structure 500 may further include a damper portion, an input end of which is connected between the first evaporator 310 and the second evaporator 320, and the damper portion may consume a certain amount of the refrigerant and may also prevent the refrigerant flowing out of the first evaporator 310 from entering the second evaporator 320.
Referring to fig. 2, in an embodiment, the refrigeration circuit 10 includes a first flow path 11 and a second flow path 12, the input ends of the first flow path 11 and the second flow path 12 are connected, the first evaporator 310 is disposed in the first flow path 11, and the second evaporator 320 is disposed in the second flow path 12; the refrigeration system 1 further includes at least two throttling components, and the two throttling components are a first throttling component 610 disposed in the first flow path 11 and a second throttling component 620 disposed in the second flow path 12.
Specifically, the first throttling part 610 and the second throttling part 620 may be provided in one or more numbers, respectively, and the types, specifications, and the like of the plurality of first throttling parts 610 and/or the plurality of second throttling parts 620 may be provided to be the same or at least partially different.
Further, the output end of the first flow path 11 is connected between the second evaporator 320 and the second throttling member 620, so that the refrigerant flowing out of the condenser 200 can enter the second evaporator 320 after passing through the first flow path 11, or the refrigerant flowing out of the condenser 200 can enter the second evaporator 320 after passing through the second throttling member 620 on the second flow path 12.
Of course, in an embodiment, the output end of the second flow path 12 may be connected between the first evaporator 310 and the first throttling part 610.
In view of the above, when the refrigeration circuit 10 includes the first flow path 11 and the second flow path 12, the input ends of the first flow path 11 and the second flow path 12 are connected, the first evaporator 310 is provided in the first flow path 11, and the second evaporator 320 is provided in the second flow path 12, the first switching member 400 is provided at the input ends of the first flow path 11 and the second flow path 12 to selectively communicate the first flow path 11 and/or the second flow path 12.
Based on this, the refrigeration system 1 further includes a control device, and the control device is electrically connected to the first switching component 400 and the compressor 100 respectively, so as to control the first switching component 400 to conduct the first flow path 11 and control the compressor 100 to start after running for a set time.
It can be understood that, before the compressor 100 is restarted after being shut down, the first switching part 400 firstly conducts the first flow path 11, so that the refrigerant flowing out of the condenser 200 enters the first evaporator 310 through the throttling part, and the state is maintained for a set time. As described above, the refrigerant after shutdown and temperature reduction in the condenser 200 enters the first evaporator 310 after throttling and pressure reduction through the throttling path, and is cooled down in advance, so that after the compressor 100 is restarted, the initial refrigeration speed of the evaporator is higher, the startup rate of the whole machine is reduced, and the reduction of energy consumption is facilitated.
The determination method of the set time is not limited, and in an embodiment, a user may input a selection scheme of the set time through an input component such as a key, a touch screen, or the like, so that the refrigeration system 1 operates according to the selection scheme in a subsequent operation process. The selection scheme may include selection schemes for individual set times of each operating cycle of the refrigeration system 1 within set conditions, such as within a specified time period. Of course, the set time may be obtained by calculation according to the operation parameters of the refrigeration system 1, obtained by experience, and the like, without limitation.
Furthermore, the utility model also provides a refrigeration device comprising a refrigeration system 1.
