As shown in fig. 1, an embodiment of the present utility model provides a refrigeration system comprising a dry filter 100, a freeze evaporator 401, a cool storage evaporator 402, a cool storage capillary 201, a cool storage capillary 202, a first valve 301, and a second valve 302. The filter-drier 100 is for receiving a treated refrigerant medium, the filter-drier 100 having at least one first outlet and at least one second outlet. The treated refrigerant medium flows into the filter-drier 100 through the inlet of the filter-drier 100 and is gradually stored in the interior of the filter-drier 100. Both the first outlet and the second outlet are used to extend capillaries into the filter-drier 100.

One end of the cryocapillary 201 communicates with the cryoevaporator 401 and the other end of the cryocapillary 201 communicates with the first outlet. That is, one end of the cryocapillary 201 protrudes into the filter-drier 100 through the first outlet.

One end of the refrigerated capillary tube 202 communicates with the refrigerated evaporator 402 and the other end of the refrigerated capillary tube 202 communicates with the second outlet. That is, one end of the refrigerated capillary 202 protrudes into the filter drier 100 through the second outlet.

The freezing capillary 201 and the refrigerating capillary 202 are connected in parallel to the filter drier 100, and do not interfere with each other.

The first valve 301 is disposed on the cryocapillary 201, and is used for controlling the on/off of the cryocapillary 201.

The second valve 302 is disposed on the refrigeration capillary 202 and is used for controlling the on/off of the refrigeration capillary 202.

The freezing evaporator 401 is used for receiving the refrigerant medium in the filter drier 100 and refrigerating the freezing compartment. The refrigerating evaporator 402 is used to receive the cooling in the dry filter 100 and cool the refrigerating compartment.

It can be appreciated that when the first valve 301 is opened, the freezing capillary 201 is controlled to be conducted, and the freezing evaporator 401 receives the refrigerant medium in the drier-filter 100, and cools the freezing compartment. When the first valve 301 is closed, the freezing capillary 201 is controlled to be closed, and the freezing evaporator 401 stops working, and the freezing chamber stops cooling.

Similarly, when the second valve 302 is opened, and the refrigeration capillary 202 is controlled to conduct, the refrigeration evaporator 402 receives the refrigeration medium in the filter-drier 100 and cools the refrigeration compartment. When the second valve 302 is closed, the refrigeration capillary 202 is controlled to stop, the refrigeration evaporator 402 stops working, and the refrigeration compartment stops refrigerating.

As will be appreciated by those skilled in the art from the foregoing description, the refrigeration system of the present utility model controls the operation of the freeze evaporator 401 and the refrigeration evaporator 402 by providing two capillaries (the freeze capillary 201 and the refrigeration capillary 202) in parallel with the dry filter 100 and controlling the on and off of the freeze capillary 201 and the refrigeration capillary 202 through the first valve 301 and the second valve 302, respectively. The utility model controls the conduction states of the freezing capillary 201 and the refrigerating capillary 202 through the first valve 301 and the second valve 302, thereby respectively controlling the working states of the freezing evaporator 401 and the refrigerating evaporator 402, and realizing that each evaporator works independently, namely, the refrigerating evaporator 402 and the freezing evaporator 401 can work simultaneously, thereby realizing that the refrigeration is carried out on two compartments at the same time.

In some embodiments, the diameter of the refrigerated capillary 202 is smaller than the diameter of the frozen capillary 201.

It will be appreciated that the refrigeration compartment requires a lower refrigeration temperature than the freezer compartment and, therefore, the refrigeration evaporator 402 requires less refrigerant than the refrigeration evaporator 401, and, therefore, the refrigeration capillary 202 is sized to have a smaller diameter than the refrigeration capillary 201, allowing for a reasonable distribution of the refrigerant medium in the filter drier 100.

In some embodiments, cryocapillary 201 extends from a first outlet into dry filter 100 and cryocapillary 202 extends from a second outlet into dry filter 100;

the inlet end of the cryocapillary 201 is maintained at a first spacing from the bottom of the filter drier 100 and the inlet end of the cryocapillary 202 is maintained at a second spacing from the bottom of the filter drier 100, the second spacing being less than the first spacing.

It should be noted that, when the refrigerating capillary 202 and the freezing capillary 201 extend into the filter drier 100, the refrigerating medium stored in the filter drier 100 is filled with the liquid at the inlet end of the pipe section, and enters the refrigerating capillary 202 and the freezing capillary 201, and if the diameters of the refrigerating capillary 202 and the freezing capillary 201 are smaller than the diameters of the freezing capillary 201, the refrigerating medium may enter the freezing capillary 201 with larger diameter preferentially if the heights of the inlet ends (the distance between the inlet end and the bottom of the filter drier 100) are consistent, and when the refrigerating medium entering the filter drier 100 is less, no refrigerating medium is likely to enter the refrigerating capillary 202. Therefore, the height of the inlet end of the refrigeration capillary 202 in the dry filter 100 is lower than the height of the freezing capillary 201 in the dry filter 100, so that the refrigeration capillary 202 is preferentially conveyed after the refrigeration medium enters the dry filter 100, and the refrigeration capillary 202 and the freezing capillary 201 can both be ensured to have the refrigeration medium entering when being simultaneously conducted.

In some embodiments, the refrigeration system further comprises a compressor 500, a first pipeline 501 is connected between the compressor 500 and the refrigeration evaporator 401, the first pipeline 501 communicates the compressor 500 and the refrigeration evaporator 401, and the first pipeline 501 is used for sending the refrigeration medium in the refrigeration evaporator 401 to the compressor 500;

a second pipeline 502 is connected between the compressor 500 and the refrigeration evaporator 402, the second pipeline 502 is communicated with the compressor 500 and the refrigeration evaporator 402, and the second pipeline 502 is used for sending the refrigeration medium in the refrigeration evaporator 402 to the compressor 500.

In some embodiments, the refrigeration system further comprises a condenser 600, a third pipeline 601 is connected to the condenser 600 and the compressor 500, the third pipeline 601 communicates the condenser 600 and the compressor 500, and the third pipeline 601 is used for sending the refrigeration medium in the compressor 500 to the condenser 600;

a fourth line 101 is connected between the condenser 600 and the filter drier 100, and the fourth line 101 is used for supplying the refrigerant medium in the condenser 600 to the filter drier 100.

In some embodiments, the outlet of the second conduit 502 and the outlet of the third conduit 601 are connected to two ports of a three-way valve, respectively, and the other end of the three-way valve is connected to the inlet of the compressor 500.

In some embodiments, the compressor 500 has a first inlet and a second inlet, the outlet end of the second conduit 502 is connected to the first inlet, and the outlet end of the third conduit 601 is connected to the second inlet.

In some embodiments, the first valve 301 is a solenoid valve and the second valve 302 is a solenoid valve.

It will be appreciated that the first and second valves 301 and 302 are connected to the refrigerator controller to control the on and off of the refrigeration capillary 202 and the freezer capillary 201. The first valve 301 and the second valve 302 may be opened separately, or the first valve 301 and the second valve 302 may be opened simultaneously.

In some embodiments, the refrigeration system further comprises a third evaporator and a third capillary tube, the filter-drier 100 further having a third outlet, one end of the third capillary tube being in communication with the third outlet, the other end of the third capillary tube being in communication with the inlet end of the third evaporator;

the third capillary is also provided with a third valve, and the third valve is used for controlling the on and off of the third capillary.

It can be understood that the third capillary tube is connected in parallel with the freezing capillary tube 201 and the refrigerating capillary tube in the drying filter 100, and the third valve is also an electromagnetic valve, and the third valve is connected with the controller of the refrigerator, so that the controller controls the opening and closing of the third valve. That is, the first valve 301, the second valve 302, and the third valve may be simultaneously opened, or the first valve 301, the second valve 302, and the third valve may be separately opened, respectively.

The utility model also provides a refrigerator which comprises the refrigerating system. Because the refrigerating system is adopted, the air conditioner at least has all the advantages of the refrigerating system, and the details are not repeated here.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
