Description
Technical Field
The invention relates to the field of refrigeration of refrigerators, in particular to a refrigeration control method of a refrigerator and the refrigerator.
Background
The current refrigeration system of the refrigerator is constructed as shown in fig. 1, in which a refrigerating chamber evaporator 7 and a freezing chamber evaporator 8 are connected in series, and a refrigerating capillary tube 5 and a freezing capillary tube 6 are connected in parallel. The solenoid valve 4 can control the cold energy to be delivered to the refrigerating capillary 5 or the freezing capillary 6. The refrigerating capillary tube 5 is directly connected to the refrigerating chamber evaporator 7, and the freezing capillary tube 6 is directly connected to the freezing chamber evaporator 8. The cold energy delivered to the refrigerating capillary 5 is delivered to the refrigerating chamber evaporator 7 first and then delivered to the compressor 1 via the freezing chamber evaporator 8, and the cold energy delivered to the refrigerating capillary 6 is delivered to the compressor 1 directly via the freezing chamber evaporator 8 without reaching the refrigerating chamber evaporator 7.
In the refrigeration control mode of the existing refrigerator, when the compressor 1 detects that the freezing chamber or the refrigerating chamber reaches the starting temperature, the electromagnetic valve 4 is switched to the refrigerating capillary 5, so that the refrigerating capacity can be transmitted to the refrigerating chamber evaporator 7 and the freezing chamber evaporator 8, and the freezing chamber and the refrigerating chamber refrigerate simultaneously. In addition, because the temperature required by the refrigerating chamber is higher, the refrigerating chamber inevitably reaches the shutdown temperature firstly to finish refrigeration, at the moment, the electromagnetic valve 4 is switched to the freezing capillary tube 6 to refrigerate for the freezing chamber, and after the refrigeration of the freezing chamber is finished, whether the freezing chamber or the refrigerating chamber reaches the startup temperature is detected, and the steps are carried out alternately. Obviously, in this way, the solenoid valve 4 is switched more frequently, and each switching of the solenoid valve 4 increases the power consumption loss during the operation process, which is a problem to be solved urgently.
Disclosure of Invention
The application provides a refrigeration control method of a refrigerator and the refrigerator, and solves the problem that in the prior art, the power consumption loss in the operation process can be increased when an electromagnetic valve is switched every time.
In a first aspect, the present application provides a refrigeration control method for a refrigerator, including: after an electromagnetic valve of the refrigerator is switched from being connected with a refrigerating capillary of the refrigerator to being connected with a freezing capillary of the refrigerator, if the temperature of a freezing chamber of the refrigerator is detected to be lower than the starting temperature of the freezing chamber or the temperature of a refrigerating chamber of the refrigerator is detected to be lower than the starting temperature of the refrigerating chamber, the electromagnetic valve is kept unchanged from being connected with the freezing capillary, so that the cold energy entering the electromagnetic valve is directly transmitted to a freezing chamber evaporator through the freezing capillary; the shutdown temperature of the refrigerating chamber is greater than that of the freezing chamber; and if the detected temperature of the freezing chamber is not less than the starting temperature of the freezing chamber and the detected temperature of the refrigerating chamber is not less than the starting temperature of the refrigerating chamber, switching the electromagnetic valve from being connected with the freezing capillary tube to being connected with the refrigerating capillary tube, so that the cold energy entering the electromagnetic valve is transmitted to the refrigerating chamber evaporator through the refrigerating capillary tube and is transmitted to the freezing chamber evaporator.
In the method, after the electromagnetic valve of the refrigerator is switched from being connected with the refrigerating capillary tube of the refrigerator to being connected with the freezing capillary tube of the refrigerator, because the shutdown temperature of the refrigerating chamber is higher than the shutdown temperature of the freezing chamber, and the refrigerating chamber needs less cold, if the temperature of the freezing chamber of the refrigerator is detected to be lower than the starting temperature of the refrigerating chamber, or the temperature of the refrigerating chamber of the refrigerator is detected to be lower than the starting temperature of the refrigerating chamber, the electromagnetic valve is kept unchanged from being connected with the freezing capillary tube, so that the cold is only supplemented to the freezing chamber evaporator, the refrigerating chamber only uses the residual cold of the refrigerating chamber evaporator, the mode of connecting the refrigerating capillary tube is switched back when the temperature of the refrigerating chamber is not lower than the starting temperature of the refrigerating chamber, and only when the temperature of the freezing chamber is detected to be not lower than the starting temperature of the freezing chamber, and when the temperature of the refrigerating chamber is not less than the starting temperature of the refrigerating chamber, the refrigerating capillary tube is switched back to be connected with the refrigerating capillary tube to supplement cold for the refrigerating chamber evaporator and the freezing chamber evaporator, so that the switching frequency of the electromagnetic valve is reduced, and the electric energy loss caused by switching the electromagnetic valve is reduced.
In an optional embodiment, in a period of time when the electromagnetic valve is kept connected with the freezing capillary tube unchanged, if the temperature of the freezing chamber is detected to be lower than the starting temperature of the freezing chamber and the temperature of the refrigerating chamber is detected to be not lower than the starting temperature of the refrigerating chamber, the temperature of the evaporator of the refrigerating chamber is detected; and if the detected temperature of the refrigerating chamber is higher than that of the refrigerating chamber evaporator, starting a refrigerating fan of the refrigerating chamber, so that the cold energy of the refrigerating chamber evaporator is transmitted to the refrigerating chamber to refrigerate the refrigerating chamber.
In the method, in a time period when the electromagnetic valve is kept to be connected with the freezing capillary tube unchanged, if the detected temperature of the freezing chamber is lower than the starting temperature of the freezing chamber and the detected temperature of the refrigerating chamber is not lower than the starting temperature of the refrigerating chamber, the refrigerating chamber needs to be refrigerated, although the electromagnetic valve is connected with the freezing capillary tube, if the detected temperature of the refrigerating chamber is higher than the temperature of the refrigerating chamber evaporator and the detected temperature of the refrigerating chamber evaporator is higher than the temperature of the refrigerating chamber evaporator, the residual cold energy of the refrigerating chamber evaporator can be used for cooling the refrigerating chamber, the refrigerating fan of the refrigerating chamber is started, and therefore the residual cold energy of the refrigerating chamber evaporator is transmitted to the refrigerating chamber to refrigerate the refrigerating chamber.
In an alternative embodiment, if the detected temperature of the refrigerating chamber is not more than the temperature of the refrigerating chamber evaporator, or the detected temperature of the refrigerating chamber is not more than the shutdown temperature of the refrigerating chamber, the refrigerating fan is turned off.
In the method, if the temperature of the refrigerating chamber is detected to be not more than the temperature of the refrigerating chamber evaporator, the residual cold quantity of the refrigerating chamber evaporator is not enough to cool the refrigerating chamber, or the temperature of the refrigerating chamber is not more than the shutdown temperature of the refrigerating chamber, the temperature of the refrigerating chamber reaches the refrigerating requirement, and therefore the refrigerating fan is turned off to save the residual cold quantity and the electric energy of the refrigerating chamber evaporator.
In an optional embodiment, after the switching the solenoid valve from connecting the freezing capillary to connecting the refrigerating capillary back, the method further comprises: detecting the temperature of the refrigerating chamber evaporator and the temperature of the freezing chamber evaporator; if the temperature of the refrigerating chamber is higher than that of the refrigerating chamber evaporator, a refrigerating fan of the refrigerating chamber is started; and/or if the temperature of the freezing chamber is greater than the temperature of the freezing chamber evaporator, starting a freezing fan of the freezing chamber.
In the above manner, after the electromagnetic valve is switched from being connected with the freezing capillary tube to being connected with the refrigerating capillary tube, the electromagnetic valve starts to transmit cold to the refrigerating capillary tube and then to the refrigerating chamber evaporator, and since the temperature of the freezing chamber is not less than the starting temperature of the freezing chamber and the temperature of the refrigerating chamber is not less than the starting temperature of the refrigerating chamber when the electromagnetic valve is just switched, the temperature of the refrigerating chamber evaporator or the temperature of the freezing chamber evaporator does not necessarily have a refrigerating effect, and therefore the temperature of the refrigerating chamber evaporator and the temperature of the freezing chamber evaporator need to be detected; if the temperature of the refrigerating chamber is higher than that of the refrigerating chamber evaporator, a refrigerating fan of the refrigerating chamber is started; and/or if the temperature of the freezing chamber is greater than that of the freezing chamber evaporator, the freezing fan of the freezing chamber is started, and the cold storage fan or the freezing fan is started when refrigeration is needed, so that electric energy is further saved.
In an alternative embodiment, the freezing fan is turned off if it is detected that the temperature of the freezing chamber is not greater than the temperature of the freezing chamber evaporator or the temperature of the freezing chamber is not greater than the shutdown temperature of the freezing chamber.
In the above mode, if the detected temperature of the freezing chamber is not greater than the temperature of the freezing chamber evaporator, it is indicated that the residual cold energy of the freezing chamber evaporator is not enough for cooling the freezing chamber, or the temperature of the freezing chamber is not greater than the shutdown temperature of the freezing chamber, it is indicated that the temperature of the freezing chamber reaches the refrigeration requirement, and therefore the freezing fan is turned off to save the residual cold energy and the electric energy of the freezing chamber evaporator.
In a second aspect, the present application provides a refrigerator comprising: the detection processing module is used for keeping the electromagnetic valve connected with the freezing capillary unchanged if the temperature of a freezing chamber of the refrigerator is detected to be lower than the starting temperature of the freezing chamber or the temperature of a refrigerating chamber of the refrigerator is detected to be lower than the starting temperature of the refrigerating chamber after the electromagnetic valve of the refrigerator is switched from being connected with the refrigerating capillary of the refrigerator to being connected with the freezing capillary of the refrigerator, so that the cold energy entering the electromagnetic valve is directly transmitted to a freezing chamber evaporator through the freezing capillary; the shutdown temperature of the refrigerating chamber is greater than that of the freezing chamber; and if the detected temperature of the freezing chamber is not less than the starting temperature of the freezing chamber and the detected temperature of the refrigerating chamber is not less than the starting temperature of the refrigerating chamber, switching the electromagnetic valve from being connected with the freezing capillary tube to being connected with the refrigerating capillary tube, so that the cold energy entering the electromagnetic valve is transmitted to the refrigerating chamber evaporator through the refrigerating capillary tube and is transmitted to the freezing chamber evaporator.
In an optional implementation, the detection processing module is further configured to: in a time period when the electromagnetic valve is kept connected with the freezing capillary tube unchanged, if the temperature of the freezing chamber is detected to be lower than the starting temperature of the freezing chamber and the temperature of the refrigerating chamber is detected to be not lower than the starting temperature of the refrigerating chamber, the temperature of the evaporator of the refrigerating chamber is detected; the refrigerator also comprises a fan control module, and the fan control module is used for: and if the temperature of the refrigerating chamber is detected to be higher than that of the refrigerating chamber evaporator through the detection processing module, starting a refrigerating fan of the refrigerating chamber, so that the cold energy of the refrigerating chamber evaporator is transmitted to the refrigerating chamber to refrigerate the refrigerating chamber.

Detailed Description
In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the specification, and it should be understood that the specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, but not limitations of the technical solutions of the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
As shown in fig. 1, a structure of a refrigeration system to which a refrigeration control method for a refrigerator provided in an embodiment of the present application is applicable is shown. Wherein, 1 is a compressor; 2 is a condenser; 3 is a dry filter; 4 is an electromagnetic valve; 5 is a refrigeration capillary; 6 is a freezing capillary; 7 is a refrigerating chamber evaporator; and 8 is a freezing chamber evaporator. As can be seen from fig. 1, the refrigerating chamber evaporator 7 and the freezing chamber evaporator 8 are connected in series, and the refrigerating capillary tube 5 and the freezing capillary tube 6 are connected in parallel. The solenoid valve 4 can control the cold energy to be delivered to the refrigerating capillary 5 or the freezing capillary 6. The refrigerating capillary tube 5 is directly connected to the refrigerating chamber evaporator 7, and the freezing capillary tube 6 is directly connected to the freezing chamber evaporator 8. The cold energy delivered to the refrigerating capillary 5 is delivered to the refrigerating chamber evaporator 7 first and then delivered to the compressor 1 via the freezing chamber evaporator 8, and the cold energy delivered to the refrigerating capillary 6 is delivered to the compressor 1 directly via the freezing chamber evaporator 8 without reaching the refrigerating chamber evaporator 7. At present, when the compressor 1 detects that the freezing chamber or the refrigerating chamber reaches the starting temperature, the electromagnetic valve 4 is switched to the refrigerating capillary 5, so that the cold energy can be transmitted to the refrigerating chamber evaporator 7 and the freezing chamber evaporator 8, and the freezing chamber and the refrigerating chamber refrigerate simultaneously. In addition, because the temperature required by the refrigerating chamber is higher, the refrigerating chamber inevitably reaches the shutdown temperature firstly to finish refrigeration, at the moment, the electromagnetic valve 4 is switched to the freezing capillary tube 6 to refrigerate for the freezing chamber, and after the refrigeration of the freezing chamber is finished, whether the freezing chamber or the refrigerating chamber reaches the startup temperature is detected, and the steps are carried out alternately. The current mode causes the electromagnetic valve 4 to be switched frequently, and the power consumption loss in the operation process is large.
For this reason, the following describes in detail a refrigeration control method of a refrigerator according to an embodiment of the present application with reference to fig. 2.
Step 201: after an electromagnetic valve of the refrigerator is switched from being connected with a refrigerating capillary of the refrigerator to being connected with a freezing capillary of the refrigerator, if the temperature of a freezing chamber of the refrigerator is detected to be lower than the starting temperature of the freezing chamber or the temperature of a refrigerating chamber of the refrigerator is detected to be lower than the starting temperature of the refrigerating chamber, the electromagnetic valve is kept unchanged from being connected with the freezing capillary, and the cold energy entering the electromagnetic valve is directly transmitted to a freezing chamber evaporator through the freezing capillary.
The shutdown temperature of the refrigerating chamber is greater than the shutdown temperature of the freezing chamber.
Step 202: and if the detected temperature of the freezing chamber is not less than the starting temperature of the freezing chamber and the detected temperature of the refrigerating chamber is not less than the starting temperature of the refrigerating chamber, switching the electromagnetic valve from being connected with the freezing capillary tube to being connected with the refrigerating capillary tube, so that the cold energy entering the electromagnetic valve is transmitted to the refrigerating chamber evaporator through the refrigerating capillary tube and is transmitted to the freezing chamber evaporator.
It should be noted that, before step 201, when the refrigerator is powered on, it may be default that neither the refrigerating chamber evaporator nor the freezing chamber evaporator has cooling capacity, the electromagnetic valve is connected to the refrigerating capillary tube of the refrigerator by default, and the refrigerator is powered on and then simultaneously refrigerates the refrigerating chamber and the freezing chamber. The shutdown temperature of the refrigerating chamber is a temperature threshold value at which the refrigerating chamber reaches the refrigerating effect and the continuous cooling is not needed for the moment, and the startup temperature of the refrigerating chamber is a temperature threshold value at which the refrigerating chamber starts to reach the refrigerating effect and the continuous cooling is needed. The shutdown temperature of the freezing chamber is a temperature threshold value at which the freezing chamber reaches the refrigeration effect and the continuous cooling is not needed for the moment, and the starting temperature of the freezing chamber is a temperature threshold value at which the freezing chamber starts to reach the refrigeration effect and the continuous cooling is needed. Obviously, the starting temperature of the refrigerating chamber is greater than the stopping temperature of the refrigerating chamber, and the starting temperature of the freezing chamber is greater than the stopping temperature of the freezing chamber. For example, the shutdown temperature of the cold room is-4 ℃ and the startup temperature of the cold room is 0 ℃. The shutdown temperature of the freezing chamber is-18 ℃, and the startup temperature of the freezing chamber is-6 ℃.
For example, in a period of time when the electromagnetic valve is kept connected with the freezing capillary tube unchanged, the temperature of the freezing chamber is detected to be-12 ℃, and the temperature of the refrigerating chamber is detected to be 1 ℃, namely the temperature of the freezing chamber still meets the requirement of the refrigerating effect at the moment, but the temperature of the refrigerating chamber does not meet the requirement of the refrigerating effect, so the refrigerating chamber needs to be refrigerated. The refrigerating chamber evaporator may have residual cold, the electromagnetic valve may not be switched to the refrigerating chamber evaporator once, and when the detected temperature of the refrigerating chamber is 1 ℃ and is higher than the temperature of the refrigerating chamber evaporator by-1 ℃, the refrigerating fan of the refrigerating chamber can be started, so that the cold of the refrigerating chamber evaporator is transmitted to the refrigerating chamber to refrigerate the refrigerating chamber.
In the above embodiment, in a period of time when the electromagnetic valve is kept connected with the freezing capillary tube unchanged, if the detected temperature of the freezing chamber is lower than the starting temperature of the freezing chamber and the detected temperature of the refrigerating chamber is not lower than the starting temperature of the refrigerating chamber, it is indicated that the refrigerating chamber needs to be refrigerated, although the electromagnetic valve is connected with the freezing capillary tube, if the detected temperature of the refrigerating chamber is higher than the temperature of the refrigerating chamber evaporator and it is indicated that the residual cold quantity of the refrigerating chamber evaporator can cool the refrigerating chamber, the refrigerating fan of the refrigerating chamber is turned on, so that the residual cold quantity of the refrigerating chamber evaporator is transmitted to the refrigerating chamber to refrigerate the refrigerating chamber.
In an optional implementation manner of steps 201 to 202, if it is detected that the temperature of the refrigerating chamber is not greater than the temperature of the refrigerating chamber evaporator, or the temperature of the refrigerating chamber is not greater than the shutdown temperature of the refrigerating chamber, the refrigerating fan is turned off.
For example, in the stage of refrigerating the refrigerating chamber and the freezing chamber simultaneously before step 201, the refrigerating chamber is first lowered to below-2 ℃ of the shutdown temperature of the refrigerating chamber, and then the refrigerating fan is turned off to save electric energy without continuously lowering the temperature. For another example, in a time period when the electromagnetic valve is kept to be connected with the freezing capillary tube unchanged, if the temperature of the refrigerating chamber rises back to the starting temperature of the refrigerating chamber for many times, the refrigerating chamber is refrigerated through the refrigerating fan, when the cold quantity of the refrigerating chamber evaporator is excessively consumed, the temperature of the refrigerating chamber is not more than the temperature of the refrigerating chamber evaporator, the refrigerating fan is started, the refrigerating chamber cannot be cooled, the temperature of the refrigerating chamber can also be increased, and therefore the refrigerating fan is also turned off to save electric energy.
In the above embodiment, if it is detected that the temperature of the refrigerating chamber is not greater than the temperature of the refrigerating chamber evaporator, it is indicated that the residual cold quantity of the refrigerating chamber evaporator is not enough to cool the refrigerating chamber, or the temperature of the refrigerating chamber is not greater than the shutdown temperature of the refrigerating chamber, it is indicated that the temperature of the refrigerating chamber has reached the refrigeration requirement, and therefore the refrigerating fan is turned off to save the residual cold quantity and the electric energy of the refrigerating chamber evaporator.
In an alternative embodiment after step 202, the temperature of the refrigerating compartment evaporator and the temperature of the freezing compartment evaporator are detected; if the temperature of the refrigerating chamber is higher than that of the refrigerating chamber evaporator, a refrigerating fan of the refrigerating chamber is started; and/or if the temperature of the freezing chamber is greater than the temperature of the freezing chamber evaporator, starting a freezing fan of the freezing chamber.
That is, after the electromagnetic valve is switched from being connected with the freezing capillary tube to being connected with the refrigerating capillary tube, the electromagnetic valve starts to transmit cold to the refrigerating capillary tube and then transmits the cold to the refrigerating chamber evaporator, and because the temperature of the freezing chamber is not less than the starting temperature of the freezing chamber and the temperature of the refrigerating chamber is not less than the starting temperature of the refrigerating chamber when the electromagnetic valve is just switched, the temperature of the refrigerating chamber evaporator or the temperature of the freezing chamber evaporator does not necessarily have a refrigerating effect, the temperature of the refrigerating chamber evaporator and the temperature of the freezing chamber evaporator need to be detected; if the temperature of the refrigerating chamber is higher than that of the refrigerating chamber evaporator, a refrigerating fan of the refrigerating chamber is started; and/or if the temperature of the freezing chamber is greater than that of the freezing chamber evaporator, the freezing fan of the freezing chamber is started, and the cold storage fan or the freezing fan is started when refrigeration is needed, so that electric energy is further saved. Obviously, in this embodiment, the refrigerating chamber is cooled to the shutdown temperature, and the solenoid valve is switched from being connected to the refrigerating capillary to being connected to the freezing capillary, and then the solenoid valve returns to step 201, so that a cycle is formed.
In an optional implementation manner of steps 201 to 202, if it is detected that the temperature of the freezing chamber is not greater than the temperature of the freezing chamber evaporator, or the temperature of the freezing chamber is not greater than the shutdown temperature of the freezing chamber, the freezing fan is turned off.
For example, if it is detected that the temperature of the freezing chamber is not greater than the temperature of the freezing chamber evaporator, it indicates that the residual cooling capacity of the freezing chamber evaporator is not enough to cool the freezing chamber, or the temperature of the freezing chamber is not greater than the shutdown temperature of the freezing chamber, it indicates that the temperature of the freezing chamber has reached the cooling requirement, and therefore the freezing fan is turned off to save the residual cooling capacity and the electric energy of the freezing chamber evaporator.
In the method of step 201 to step 202, after the electromagnetic valve of the refrigerator is switched from being connected with the refrigerating capillary tube of the refrigerator to being connected with the freezing capillary tube of the refrigerator, because the shutdown temperature of the refrigerating chamber is higher than the shutdown temperature of the freezing chamber and the refrigerating chamber needs less cold, if the detected temperature of the freezing chamber of the refrigerator is lower than the startup temperature of the refrigerating chamber or the detected temperature of the refrigerating chamber of the refrigerator is lower than the startup temperature of the refrigerating chamber, the electromagnetic valve is kept unchanged from being connected with the refrigerating capillary tube, so that only the refrigerating chamber evaporator is supplemented with cold, the refrigerating chamber only uses the residual cold of the refrigerating chamber evaporator, the mode of being connected with the refrigerating capillary tube is switched back when the temperature of the refrigerating chamber is not lower than the startup temperature of the refrigerating chamber, and only when the detected temperature of the freezing chamber is not lower than the startup temperature of the freezing chamber, and when the temperature of the refrigerating chamber is not less than the starting temperature of the refrigerating chamber, the refrigerating capillary tube is switched back to be connected with the refrigerating capillary tube to supplement cold for the refrigerating chamber evaporator and the freezing chamber evaporator, so that the switching frequency of the electromagnetic valve is reduced, and the electric energy loss caused by switching the electromagnetic valve is reduced.
As shown in fig. 3, the present application provides a refrigerator including: the detection processing module 301 is configured to, after an electromagnetic valve of a refrigerator is switched from being connected to a refrigeration capillary of the refrigerator to being connected to a freezing capillary of the refrigerator, if it is detected that a temperature of a freezing chamber of the refrigerator is lower than a starting temperature of the freezing chamber, or a temperature of a refrigerating chamber of the refrigerator is lower than the starting temperature of the refrigerating chamber, keep the electromagnetic valve connected to the freezing capillary unchanged, so that the cold energy entering the electromagnetic valve is directly transmitted to a freezing chamber evaporator through the freezing capillary; the shutdown temperature of the refrigerating chamber is greater than that of the freezing chamber; if the temperature of the freezing chamber is detected to be not less than the starting temperature of the freezing chamber and the temperature of the refrigerating chamber is detected to be not less than the starting temperature of the refrigerating chamber, the electromagnetic valve is switched from being connected with the freezing capillary tube to being connected with the refrigerating capillary tube, so that the cold energy entering the electromagnetic valve is transmitted to the refrigerating chamber evaporator through the refrigerating capillary tube and is transmitted to the freezing chamber evaporator
In an optional implementation, the detection processing module 301 is further configured to: in a time period when the electromagnetic valve is kept connected with the freezing capillary tube unchanged, if the temperature of the freezing chamber is detected to be lower than the starting temperature of the freezing chamber and the temperature of the refrigerating chamber is detected to be not lower than the starting temperature of the refrigerating chamber, the temperature of the evaporator of the refrigerating chamber is detected; the refrigerator further comprises a blower control module 302, the blower control module 302 being configured to: if the temperature of the refrigerating chamber is detected to be higher than that of the refrigerating chamber evaporator by the detection processing module 301, a refrigerating fan of the refrigerating chamber is started, so that the cold energy of the refrigerating chamber evaporator is transmitted to the refrigerating chamber to refrigerate the refrigerating chamber.
