Refrigerator can be direct cooling refrigerator or air cooling type refrigerator, and compression-type refrigeration cycle can be used to be used as low-temperature receiver. As shown in Figure 1, cooling cycle system generality may include compressor 10, condenser 20, capillary and evaporator etc..Refrigerant exists Heat exchange is directly or indirectly occurred with storing compartment with low temperature in evaporator, absorbs the heat of storing compartment and gasification, is generated Low-pressure steam sucked by compressor 10, be discharged with high pressure after the compression of compressor 10, the high-pressure gaseous system that compressor 10 is discharged Cryogen enters condenser 20, by the cooling water or air cooling of room temperature, condenses into highly pressurised liquid, highly pressurised liquid flows through capillary section Stream, becomes the gas-fluid two-phase mixture of low-pressure low-temperature, into evaporator, liquid refrigerant therein evaporates system in evaporator Cold, the low-pressure steam of generation is sucked by compressor 10 again, so in cycles, is constantly recycled, is realized the lasting system of refrigerator It is cold.

Usually, the cooling cycle system of refrigerator can be single loop system or binary cycle system etc., be made in single loop system The trend of cryogen is compressor 10-- condenser 20-- capillaries -- evaporator -- compressor 10, wherein capillary and evaporator It is single.As shown in Figure 1, there are two independent capillary and evaporators for binary cycle system, it is respectively corresponding with refrigerating chamber Refrigerate capillary 40, refrigeration evaporator 50 and freezing capillary 60 corresponding with freezing chamber and refrigerating evaporator 70.Refrigerator controls System control opens or closes the refrigerant towards refrigerating chamber or freezing chamber, to accurately control the temperature of refrigerating chamber and freezing chamber Degree.

As shown in Figure 1, the cooling cycle system of refrigerator may also include regenerator 30, the temperature flowed out from condenser 20 is higher Liquid refrigerant, carry out heat exchange in regenerator 30 with from the lower refrigerant vapour of evaporator temperature, make liquid system Cryogen is subcooled, and the liquid refrigerant of gaseous refrigerant overheat, the supercooling after the heat exchange of regenerator 30 flows into capillary so that warp The liquid of refrigerant is more after capillary-compensated, and gaseous state is few, improves refrigeration effect；The gaseous state of overheat after the heat exchange of regenerator 30 Refrigerant is sucked by compressor 10, prevents liquid refrigerant from returning to compressor 10 and liquid hit phenomenon occurs.
