Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, for example to a refrigeration device and a method, apparatus and storage medium for controlling a refrigeration device. BACKGROUND

[0002] At present, people's life has been inseparable from the refrigerator. And the compressor is a common component in various refrigerators. The compressor is used to pressurize the refrigerant. In the case of pressurizing the refrigerant by the compressor, the compressor will generate a large amount of heat. If the heat of the compressor is not dissipated in time, the temperature of the compressor will be too high. Thus, it will reduce the refrigeration effect of the whole refrigerator, and even cause the compressor short circuit, so that the refrigerator fails to stop. Therefore, during the operation of the compressor, how to continuously dissipate heat for the compressor is a key problem that cannot be ignored.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: In the related art, different ways such as pipelines or heat exchange modules are usually used to exchange heat between the compressor and the evaporator. In this way, the continuous heat dissipation for the compressor can be realized while defrosting the evaporator. However, when the heat exchange is performed between the compressor and the evaporator, the waste heat of the compressor cannot be completely absorbed by the evaporator, and the excess heat will cause the temperature of the freezing chamber where the evaporator is located to rise. Thus, the refrigeration effect of the freezing chamber is poor.

[0036] The term "corresponding" can refer to an association relationship or a binding relationship, A corresponding to B means that there is an association relationship or a binding relationship between A and B.

[0037] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other in the case of no conflict.

[0038] The refrigeration equipment provided by the embodiments of the present disclosure continuously inputs the fusion solution to the regenerator by using the pump, so that the regenerator can continuously dissipate heat for the compressor by using the fusion solution. In this way, the heat of the compressor is absorbed by the regenerator, and there is no heat exchange between the compressor and the evaporator, and the temperature of the freezing chamber where the evaporator is located will not rise due to the heat of the compressor. Therefore, the heat of the compressor can be continuously dissipated while reducing the influence on the refrigeration effect of the freezing chamber.

[0039] In some embodiments, the refrigeration equipment is a refrigerator. The refrigerator includes a refrigeration pipeline. The refrigeration pipeline is used to refrigerate the freezing chamber of the refrigerator.

[0040] As shown in Figure 1 The refrigeration pipeline includes a compressor 1, a second condenser 2, a heat exchanger 3, a third throttling valve 4, and a third evaporator 5. Wherein, there is refrigerant in the refrigeration pipeline. The refrigerant circulates in the refrigeration pipeline to achieve refrigeration. One end of the compressor 1 is connected with one end of the second condenser 2. The other end of the compressor 1 is connected with one end of the third evaporator 5. The other end of the second condenser 2 is connected with one end of the heat exchanger 3. The other end of the heat exchanger 3 is connected with one end of the third throttling valve 4. The other end of the third throttling valve 4 is connected with the other end of the third evaporator 5. The third evaporator 5 is located at the freezing chamber of the refrigerator. In the case that the compressor is started, the compressor 1 converts the low-temperature and low-pressure first gaseous refrigerant from the third evaporator 5 into high-temperature and high-pressure second gaseous refrigerant by doing work, and delivers the second gaseous refrigerant to the second condenser 2. At the same time, the temperature of the compressor rises and generates heat. The heat is absorbed by the regenerator, and the temperature of the compressor decreases. The second condenser 2 releases heat to the external environment, reduces the temperature of the second gaseous refrigerant, and obtains the first liquid refrigerant with medium temperature and low pressure. Then the first liquid refrigerant is delivered to the heat exchanger 3. The liquid refrigerant in the heat exchanger 3 releases heat again to reduce the temperature and obtain the second liquid refrigerant. Then the second liquid refrigerant is cooled and decompressed by the third throttling valve 4 to obtain the low-temperature and low-pressure gas-liquid mixed refrigerant. The gas-liquid mixed refrigerant includes liquid refrigerant and gaseous refrigerant. Then the gas-liquid mixed refrigerant absorbs external heat through the third evaporator 5 to achieve refrigeration. At the same time, the gas-liquid mixed refrigerant becomes the low-temperature and low-pressure first gaseous refrigerant and is re-input into the compressor. In this way, the refrigeration pipeline realizes the reverse Carnot cycle by using the circulation of the refrigerant in the refrigeration pipeline, thereby realizing the refrigeration effect of the refrigerator.

[0041] In combination Figure 2As shown, the embodiment of the present disclosure provides a refrigeration device, comprising: a regenerator 6 and a pump 7. Wherein the regenerator 6 is connected with the pump 7. The regenerator is used to dissipate heat of a compressor of the refrigeration device by using a fusion solution. The pump 7 is used to input the fusion solution to the regenerator.

[0042] By using the refrigeration device provided by the embodiment of the present disclosure, the fusion solution is continuously input to the regenerator by using the pump, so that the regenerator can continuously dissipate heat of the compressor by using the fusion solution. By absorbing heat of the compressor by the regenerator, heat exchange between the compressor and the evaporator will not occur, and the temperature of the freezing chamber where the evaporator is located will not rise due to the heat of the compressor. Therefore, the compressor can be continuously cooled while reducing the influence on the refrigeration effect of the freezing chamber.

[0043] Further, the temperature of the compressor is higher than the temperature of the fusion solution.

[0044] In some embodiments, when the refrigeration module uses the compressor for refrigeration, the compressor needs to work on the refrigerant circulating in the refrigeration module, that is, to pressurize and heat the refrigerant circulating in the refrigeration module, which causes the temperature of the compressor to rise rapidly. The regenerator is in contact with the surface of the compressor. Because there is a fusion solution in the regenerator, and the temperature of the fusion solution is lower than the surface temperature of the compressor. Therefore, the heat of the compressor can be absorbed in the regenerator in contact with the compressor to heat the fusion solution. The heat dissipation of the compressor is achieved. Then the pump inputs the fusion solution to the regenerator, so that the temperature of the fusion solution in the regenerator is always lower than the temperature of the compressor, and the continuous heat dissipation of the compressor is achieved.

[0045] In some embodiments, the temperature of the compressor is higher than the temperature of the fusion solution. When the refrigeration module uses the compressor for refrigeration, the compressor needs to work on the refrigerant circulating in the refrigeration module, that is, to pressurize and heat the refrigerant circulating in the refrigeration module, which causes the temperature of the compressor to rise rapidly. The distance between the regenerator and the compressor is less than a preset distance, so that the regenerator can absorb the heat of the compressor. Because there is a fusion solution in the regenerator, and the temperature of the fusion solution is lower than the surface temperature of the compressor. Therefore, the heat of the compressor can be absorbed in the regenerator to heat the fusion solution. The heat dissipation of the compressor is achieved. Then the pump inputs the fusion solution to the regenerator, so that the temperature of the fusion solution in the regenerator is always lower than the temperature of the compressor, and the continuous heat dissipation of the compressor is achieved.

[0046] In some embodiments, the regenerator is configured to absorb heat from the compressor using a fusion solution to obtain a first refrigerant and a first absorbent. The fusion solution is a mixed solution including the refrigerant and the absorbent. The regenerator is configured to heat the fusion solution by absorbing heat from the compressor. The refrigerant in the fusion solution is heated to become a high-temperature and high-pressure refrigerant vapor, i.e., the first refrigerant. The absorbent in the fusion solution is heated to become a high-temperature and high-pressure absorbent solution, i.e., the first absorbent. In this way, the heat from the compressor can drive the regenerator to cause the fusion solution in the regenerator to absorb heat, and the refrigerant and the absorbent in the fusion solution to separate from each other to obtain the first refrigerant and the first absorbent.

[0047] Further, the refrigeration device further includes a refrigerant pipeline, an absorbent pipeline, and an absorber. The first output end of the regenerator is connected to the first input end of the absorber through the refrigerant pipeline. The second output end of the regenerator is connected to the second input end of the absorber through the absorbent pipeline. The output end of the absorber is connected to the input end of the pump. The refrigerant pipeline is configured to transport the first refrigerant. The absorbent pipeline is configured to transport the first absorbent. The absorber is configured to cause the second refrigerant and the second absorbent to undergo a phase change and release heat generated during the phase change to obtain the fusion solution. The second refrigerant is the first refrigerant from the refrigerant pipeline. The second absorbent is the first absorbent from the absorbent pipeline. In this way, the second refrigerant from the refrigerant pipeline and the second absorbent from the absorbent pipeline are mixed in the absorber to obtain a second fusion solution. The absorber is then configured to release heat from the second fusion solution to obtain the fusion solution. The pump is then configured to transport the fusion solution to the regenerator. In this way, the regenerator can continuously absorb heat from the compressor using the fusion solution, and the heat from the compressor can be continuously dissipated.

[0048] Further, the first refrigerant and the second refrigerant are both refrigerant vapor.

[0049] In combination Figure 3As shown, the embodiment of the present disclosure provides a refrigeration device, comprising a regenerator 6, a pump 7, a refrigerant pipeline 8, an absorbent pipeline 9 and an absorber 10. The input end of the regenerator 6 is connected with the output end of the pump 7. The first output end of the regenerator 6 is connected with the first input end of the absorber 10 through the refrigerant pipeline 8. The second output end of the regenerator 6 is connected with the second input end of the absorber 10 through the absorbent pipeline 9. The output end of the absorber 10 is connected with the input end of the pump 7. The pump is used to input the fusion solution to the regenerator. The regenerator is used to absorb the heat of the compressor by using the fusion solution to obtain the first refrigerant and the first absorbent. The first refrigerant is the refrigerant vapor with high temperature and high pressure. The first absorbent is the absorbent solution with high temperature and high pressure. The first refrigerant becomes the second refrigerant through the refrigerant pipeline. The second refrigerant is the refrigerant vapor. The first absorbent becomes the second absorbent through the absorbent pipeline. The second absorbent is the absorbent solution. The second refrigerant and the second absorbent are dissolved in the absorber to produce phase change. For example, the second refrigerant is converted from vapor to solution to produce phase change in the case of being absorbed by the second absorbent; and the second absorbent also produces phase change in the case of absorbing the second refrigerant. A large amount of heat is generated in the process of phase change. The absorber releases the heat generated in the process of phase change to generate the fusion solution with temperature lower than that of the compressor.

[0050] Further, the absorbent pipeline comprises a first throttling valve. The input end of the first throttling valve is connected with the second output end of the regenerator. The output end of the first throttling valve is connected with the second input end of the absorber. The first throttling valve is used to reduce the pressure of the first absorbent to obtain the second absorbent. In this way, the pressure and temperature of the obtained second absorbent can be reduced by using the first throttling valve to reduce the pressure of the first absorbent. Thus, the second refrigerant is more easily dissolved in the second absorbent.

[0051] In combination Figure 4As shown, the embodiment of the present disclosure provides a refrigeration device, comprising a regenerator 6, a pump 7, a refrigerant pipeline 8, a first throttling valve 11 and an absorber 10. The input end of the regenerator 6 is connected with the output end of the pump 7. The first output end of the regenerator 6 is connected with the first input end of the absorber 10 through the refrigerant pipeline 8. The input end of the first throttling valve 11 is connected with the second output end of the regenerator 6. The output end of the first throttling valve 11 is connected with the second input end of the absorber 10. The output end of the absorber 10 is connected with the input end of the pump 7. The pump is used to input the fusion solution to the regenerator. The regenerator is used to absorb the heat of the compressor by the fusion solution to obtain the first refrigerant and the first absorbent. The absorber is used to make the second refrigerant and the second absorbent produce phase change and release the heat generated in the phase change process to obtain the fusion solution with a temperature lower than that of the compressor. The first refrigerant is the refrigerant vapor with high temperature and high pressure. The first absorbent is the absorbent solution with high temperature and high pressure. The first refrigerant becomes the second refrigerant through the refrigerant pipeline. The second refrigerant is the refrigerant vapor. The first absorbent becomes the second absorbent by pressure reduction through the first throttling valve. The second absorbent is the absorbent solution with low temperature and low pressure.

[0052] Further, the refrigerant pipeline comprises a first condenser and a heat absorption module. The input end of the first condenser is connected with the first output end of the regenerator. The output end of the first condenser is connected with the input end of the heat absorption module. The output end of the heat absorption module is connected with the first input end of the absorber. The first condenser is used to release the heat in the first refrigerant to obtain the third refrigerant. The heat absorption module is used to absorb the heat by the third refrigerant to obtain the second refrigerant. In this way, the heat in the first refrigerant is first released by the first condenser to obtain the third refrigerant, and then the heat is absorbed by the heat absorption module to obtain the second refrigerant. So as to deliver the second refrigerant to the absorber to be dissolved with the second absorbent.

[0053] Further, the heat absorption module is used to absorb the heat of the heat exchanger by the third refrigerant to obtain the second refrigerant. In this way, the supercooling degree of the refrigerant in the heat exchanger of the refrigeration pipeline is improved by the heat absorption module, thereby increasing the refrigeration capacity of the refrigeration pipeline and accelerating the cooling speed of the refrigeration capacity of the refrigeration pipeline. At the same time, the temperature and pressure of the refrigerant in the heat exchanger of the refrigeration pipeline can be reduced by the heat absorption module, thereby improving the condensation effect of the refrigerator.

[0054] In some embodiments, the heat absorption module is in contact with the heat exchanger, so that the heat absorption module can absorb the heat of the heat exchanger by the third refrigerant. Or, the heat absorption module is not in contact with the heat exchanger, but there is heat exchange between the heat absorption module and the heat exchanger, so that the heat absorption module can absorb the heat of the heat exchanger by the third refrigerant.

[0055] In combination Figure 5As shown, the embodiment of the present disclosure provides a refrigeration device, comprising a regenerator 6, a pump 7, a first condenser 12, a heat absorption module 13, a first throttling valve 11 and an absorber 10. Wherein, the input end of the regenerator 6 is connected with the output end of the pump 7. The first output end of the regenerator 6 is connected with the input end of the first condenser 12. The output end of the first condenser 12 is connected with the input end of the heat absorption module 13. The output end of the heat absorption module 13 is connected with the first input end of the absorber 10. The input end of the first throttling valve 11 is connected with the second output end of the regenerator 6. The output end of the first throttling valve 11 is connected with the second input end of the absorber 10. The output end of the absorber 10 is connected with the input end of the pump 7. The pump is used to input the fusion solution to the regenerator. The regenerator is used to absorb the heat of the compressor by using the fusion solution, to obtain the first refrigerant and the first absorbent. The absorber is used to make the second refrigerant and the second absorbent produce phase change, and release the heat generated in the phase change process, to obtain the fusion solution with a temperature lower than that of the compressor. The first refrigerant is a high-temperature and high-pressure refrigerant vapor. The first absorbent is a high-temperature and high-pressure absorbent solution. The first refrigerant releases heat to the external environment through the first condenser, and becomes the third refrigerant. The third refrigerant is a medium-temperature and high-pressure refrigerant solution. Then the third refrigerant absorbs the heat of the heat exchanger through the heat absorption module, and becomes the refrigerant vapor, i.e. the second refrigerant. The first absorbent becomes the second absorbent by pressure reduction through the first throttling valve. The second absorbent is a low-temperature and low-pressure absorbent solution.

[0056] Optionally, the heat absorption module comprises a first evaporator. The input end of the first evaporator is connected with the output end of the first condenser. The output end of the first evaporator is connected with the first input end of the absorber. The first evaporator is used to absorb heat by using the third refrigerant, to obtain the second refrigerant. In this way, the first evaporator can absorb heat from the refrigerant in the heat exchanger of the refrigeration pipeline, and the supercooling degree of the refrigerant is improved. Thus, the refrigeration capacity of the refrigeration pipeline is increased, and the cooling speed of the refrigeration capacity of the refrigeration pipeline is accelerated.

[0057] In some embodiments, the first evaporator is in contact with the heat exchanger, so that the first evaporator can absorb the heat of the heat exchanger by using the third refrigerant. Or, the first evaporator is not in contact with the heat exchanger, but there is heat exchange between the first evaporator and the heat exchanger, so that the first evaporator can absorb the heat of the heat exchanger by using the third refrigerant.

[0058] In combination Figure 6As shown, the embodiment of the present disclosure provides a refrigeration device, comprising a regenerator 6, a pump 7, a first condenser 12, a first evaporator 14, a first throttling valve 11 and an absorber 10. Wherein, the input end of the regenerator 6 is connected with the output end of the pump 7. The first output end of the regenerator 6 is connected with the input end of the first condenser 12. The output end of the first condenser 12 is connected with the input end of the first evaporator 14. The output end of the first evaporator 14 is connected with the first input end of the absorber 10. The input end of the first throttling valve 11 is connected with the second output end of the regenerator 6. The output end of the first throttling valve 11 is connected with the second input end of the absorber 10. The output end of the absorber 10 is connected with the input end of the pump 7. The pump is used for inputting a fusion solution to the regenerator. The regenerator is used for absorbing heat of a compressor by using the fusion solution, obtaining a first refrigerant and a first absorbent. The absorber is used for causing a second refrigerant and a second absorbent to generate a phase change and releasing heat generated in the phase change process, obtaining a fusion solution with a temperature lower than that of the compressor. The first refrigerant is a high-temperature and high-pressure refrigerant vapor. The first absorbent is a high-temperature and high-pressure absorbent solution. The first refrigerant releases heat to an external environment through the first condenser, becoming a third refrigerant. The third refrigerant is a medium-temperature and high-pressure refrigerant solution. Then the third refrigerant absorbs heat of a heat exchanger through the first evaporator, becoming a refrigerant vapor, that is, the second refrigerant. The first absorbent is reduced in pressure through the first throttling valve, becoming the second absorbent. The second absorbent is a low-temperature and low-pressure absorbent solution.

[0059] Optionally, the heat absorption module comprises a second throttling valve and a second evaporator. The input end of the second throttling valve is connected with the output end of the first condenser. The output end of the second throttling valve is connected with the input end of the second evaporator. The output end of the second evaporator is connected with the first input end of the absorber. The second throttling valve is used for reducing the pressure of the third refrigerant, obtaining a fourth refrigerant. The second evaporator is used for absorbing heat by using the fourth refrigerant, obtaining the second refrigerant. In this way, the third refrigerant is first reduced in pressure by using the second throttling valve, so as to reduce the temperature and pressure of the fourth refrigerant. Then more heat is absorbed from the refrigerant in the heat exchanger of the refrigeration pipeline by using the second evaporator, improving the supercooling degree of the refrigerant. Thus, the refrigeration capacity of the refrigeration pipeline is increased, and the cooling speed of the refrigeration capacity of the refrigeration pipeline is accelerated.

[0060] In some embodiments, the second evaporator is in contact with the heat exchanger, so that the second evaporator can absorb heat of the heat exchanger by using the third refrigerant. Or, the second evaporator is not in contact with the heat exchanger, but there is heat exchange between the second evaporator and the heat exchanger, so that the second evaporator can absorb heat of the heat exchanger by using the third refrigerant.

[0061] In combination Figure 7As shown, the embodiment of the present disclosure provides a refrigeration device, comprising a regenerator 6, a pump 7, a first condenser 12, a second evaporator 15, a second throttling valve 16, a first throttling valve 11 and an absorber 10. The input end of the regenerator 6 is connected with the output end of the pump 7. The first output end of the regenerator 6 is connected with the input end of the first condenser 12. The output end of the first condenser 12 is connected with the input end of the second throttling valve 16. The output end of the second throttling valve 16 is connected with the input end of the second evaporator 15. The output end of the second evaporator 15 is connected with the first input end of the absorber 10. The input end of the first throttling valve 11 is connected with the second output end of the regenerator 6. The output end of the first throttling valve 11 is connected with the second input end of the absorber 10. The output end of the absorber 10 is connected with the input end of the pump 7. The pump is used to input the fusion solution to the regenerator. The regenerator is used to absorb the heat of the compressor by the fusion solution to obtain the first refrigerant and the first absorbent. The absorber is used to make the second refrigerant and the second absorbent produce phase change and release the heat generated in the phase change process to obtain the fusion solution with a temperature lower than that of the compressor. The first refrigerant is a high-temperature and high-pressure refrigerant vapor. The first absorbent is a high-temperature and high-pressure absorbent solution. The first refrigerant releases heat to the external environment through the first condenser to become the third refrigerant. The third refrigerant is a medium-temperature and high-pressure refrigerant solution. Then the third refrigerant is depressurized by the second throttling valve to obtain the fourth refrigerant. The fourth refrigerant is a low-temperature and low-pressure gas-liquid mixed refrigerant. The gas-liquid mixed refrigerant includes refrigerant vapor and refrigerant solution. Then the fourth refrigerant absorbs the heat of the heat exchanger through the second evaporator to become the refrigerant vapor, i.e., the second refrigerant. The first absorbent is depressurized by the first throttling valve to become the second absorbent.

[0062] In this way, the regenerator, the pump, the first condenser, the second evaporator, the second throttling valve, the first throttling valve and the absorber form an absorption heat pump device. Only the power supply needs to be provided to the pump in the absorption heat pump device to overcome the refrigerant flow resistance and the gravitational potential energy. The refrigerant can be circulated between the regenerator, the pump, the first condenser, the second evaporator, the second throttling valve and the absorber, and the absorbent can be circulated between the pump, the regenerator, the first throttling valve and the absorber. Thus, the heat of the refrigerant in the compressor and the heat exchanger of the refrigeration pipeline can be respectively absorbed by the regenerator and the first condenser, the temperature and the pressure of the refrigerant are reduced, and the condensation effect of the refrigeration pipeline is improved. Therefore, the temperature of the compressor can be reduced more while saving energy. The probability of the extreme operation of the compressor under high-temperature working conditions is reduced. Thus, the operation efficiency of the compressor is improved, and the reliability of the compressor is ensured. At the same time, since the temperature of the compressor is reduced more, the efficiency of the compressor is improved, the refrigeration effect of the refrigeration pipeline is increased, and energy is further saved. In addition, since the efficiency of the compressor is improved, the compressor can be replaced with a compressor with a smaller cost under the condition that the refrigeration effect is the same. The cost of the compression refrigeration system is reduced.

[0063] Further, the refrigeration device further comprises a heating module. The heating module is used to supplement heat in the case of insufficient heat of the compressor. In some embodiments, the heating module is a heating wire.

[0064] In some embodiments, if the heat of the compressor is insufficient, the fusing solution of the regenerator cannot absorb enough heat. The heat of the compressor cannot drive the regenerator, and the refrigerant and the absorbent in the fusing solution cannot be separated. In this case, the heating wire needs to be turned on to supplement heat. The regenerator can absorb enough heat to separate the refrigerant and the absorbent in the fusing solution from the heat absorbed by the fusing solution, to obtain the first refrigerant and the first absorbent. Thus, the absorption heat pump device can operate normally.

[0065] The above description and drawings sufficiently illustrate the embodiments of the present disclosure to enable one skilled in the art to practice them. Other embodiments can include structural and other changes. The embodiments represent only the possible variations. Individual components and functions are optional unless explicitly required, and the order of operations can be changed. Parts and features of some embodiments can be included in or replace parts and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the drawings, and can be variously modified and changed without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.

[0066] In combination Figure 8 As shown, the embodiments of the present disclosure provide a method for controlling a refrigeration device, applied to the refrigeration device described above. The method comprises:

[0067] Step S101, the refrigeration device detects whether the refrigeration module is started.

[0068] Step S102, the refrigeration device starts the pump to provide the fusing solution for heat dissipation of the compressor to the regenerator in the case of starting of the refrigeration module.

[0069] By using the method for controlling a refrigeration device provided by the embodiments of the present disclosure, the fusing solution is continuously input to the regenerator by the pump, so that the regenerator can continuously dissipate heat of the compressor by using the fusing solution. In this way, the heat of the compressor is absorbed by the regenerator, and there is no heat exchange between the compressor and the evaporator, and the temperature of the refrigeration chamber where the evaporator is located will not rise due to the heat of the compressor. Thus, the compressor can be continuously dissipated in the case of reducing the influence on the refrigeration effect of the refrigeration chamber.

[0070] In combination Figure 9As shown, the embodiment of the present disclosure provides a device 19 for controlling a refrigeration device, applied to the refrigeration device described above. The device comprises a detection module 17 and a starting module 18. The detection module 17 is configured to detect whether the compressor is started. The starting module 18 is configured to start the pump to provide the regenerator with the fusion solution for heat dissipation of the compressor in the case that the refrigeration module is started.

[0071] By using the device for controlling a refrigeration device provided by the embodiment of the present disclosure, the pump is used to continuously input the fusion solution to the regenerator, so that the regenerator can continuously dissipate the heat of the compressor by using the fusion solution. In this way, by absorbing the heat of the compressor by the regenerator, there is no heat exchange between the compressor and the evaporator, and the temperature of the freezer room where the evaporator is located will not rise due to the heat of the compressor. Thus, the heat of the compressor can be continuously dissipated while reducing the influence on the refrigeration effect of the freezer room.

[0072] The embodiment of the present disclosure provides a computer readable storage medium, which stores computer executable instructions, and the computer executable instructions are configured to execute the method for controlling a refrigeration device.
