Shown in Fig. 1～2; Because freezer evaporator 10 and 11 series connection of the first fresh-keeping chamber evaporimeter; Therefore; When 10 pairs of refrigerating chambers of freezer evaporator freezed, the first fresh-keeping chamber evaporimeter 11 was also freezing to the fresh-keeping chamber evaporimeter, thereby made freezer temperature and fresh-keeping chamber temperature all constant in below-25 degrees centigrade.Thus, under the condition that satisfies the refrigeration requirement, reduced energy consumption.
The first return-air heat exchanging segment 15 is used to make the cold-producing medium from the first fresh-keeping chamber evaporimeter 11 and the second fresh-keeping chamber evaporimeter, 12 entering refrigerator evaporators 14 to carry out heat exchange with the cold-producing medium that gets into the freezer evaporators 10 and the second fresh-keeping chamber evaporimeter 12 from device for drying and filtering 6, and the second return-air heat exchanging segment 16 is used to make the cold-producing medium that returns the cold-producing medium of compressor 1 and get into freezer evaporators 10 from device for drying and filtering 6 from refrigerator evaporator 14 to carry out heat exchange.Because the temperature of cold-producing medium can influence refrigeration; In other words, when temperature reached a certain scope, refrigeration was better; Therefore; Carry out heat exchange through the first return-air heat exchanging segment 15 and 16 pairs of cold-producing mediums of the second return-air heat exchanging segment, cold-producing medium is reached and the better corresponding temperature range of refrigeration, make refrigeration better.
As shown in Figure 1; First magnetic valve 7, second magnetic valve 8 and the 3rd magnetic valve 9 be have first opening, the triple valve of second opening and the 3rd opening; Can said refrigeration system be switched between normal refrigeration mode and fresh-keeping chamber quick-frozen refrigeration mode through controlling first magnetic valve, second magnetic valve and the 3rd magnetic valve, thereby realize big reefer space quick-frozen function.Thus, make temperature of refrigerating chamber constant, make freezer temperature and fresh-keeping chamber temperature all constant, satisfy the needs of user refrigerator with big reefer space and quick-frozen function below-25 degrees centigrade at 2 degrees centigrade～8 degrees centigrade.
The normal refrigeration mode of describing according to the refrigeration system that is used for three direct-cooled mechanical type refrigerators of the embodiment of the invention with reference to figure 1 below.
As shown in Figure 1, when the refrigerator operate as normal, high temperature and high pressure gaseous refrigerant flows into first condenser 2 from the outlet of compressor 1, becomes the cryogenic high pressure liquid refrigerant through condensation.Then, the cryogenic high pressure liquid refrigerant flows through anti-condensation pipe 4, second condenser 3 and device for drying and filtering 6 successively.Dried cryogenic high pressure liquid refrigerant flows into capillary 5 from the outlet of device for drying and filtering 6, becomes the low-temp low-pressure liquid refrigerant through throttling expansion.The low-temp low-pressure liquid refrigerant flows out from the outlet of capillary 5; Flow through first opening and the 3rd opening of first magnetic valve 7; Flow into the freezer evaporator 10 and the first fresh-keeping chamber evaporimeter 11 then successively, make freezer temperature and fresh-keeping chamber temperature all constant below-25 degrees centigrade through evaporation.Then; Cold-producing medium flows out from the outlet of the first fresh-keeping chamber evaporimeter 11, flows through the 3rd opening and first opening of second magnetic valve 8, flows into refrigerator evaporator 14 then; Become gaseous refrigerant through evaporation, thereby make temperature of refrigerating chamber constant at 2 degrees centigrade～8 degrees centigrade.At last, gaseous refrigerant flows out from the outlet of refrigerator evaporator 14, flows through the 3rd opening and first opening and the second return-air heat exchanging segment 16 of the 3rd magnetic valve 9, returns compressor 1 then, thereby accomplishes the circulation of cold-producing medium.
The fresh-keeping chamber quick-frozen refrigeration mode of describing according to the refrigeration system that is used for three direct-cooled mechanical type refrigerators of the embodiment of the invention with reference to figure 2 below.
As shown in Figure 2, when the needs refrigerator had big reefer space quick-frozen function, high temperature and high pressure gaseous refrigerant flowed into first condenser 2 from the outlet of compressor 1, becomes the cryogenic high pressure liquid refrigerant through condensation.Then, the cryogenic high pressure liquid refrigerant flows through anti-condensation pipe 4, second condenser 3 and device for drying and filtering 6 successively.Dried cryogenic high pressure liquid refrigerant flows into capillary 5 from the outlet of device for drying and filtering 6, becomes the low-temp low-pressure liquid refrigerant through throttling expansion.The low-temp low-pressure liquid refrigerant flows to first magnetic valve 7 from the outlet of capillary 5, is divided into first cold-producing medium part and the second cold-producing medium part, and regulates the flow of first cold-producing medium part and second cold-producing medium part through the aperture of controlling first magnetic valve 7.First cold-producing medium partly flows through first opening and the 3rd opening of first magnetic valve 7, flows into freezer evaporator 10 first fresh-keeping chamber evaporimeters 11 then successively, makes freezer temperature and fresh-keeping chamber temperature all constant in below-25 degrees centigrade through evaporation.Simultaneously, second cold-producing medium partly flows through first opening and second opening of first magnetic valve 7, flows into the second fresh-keeping chamber evaporimeter 12 then, makes the fresh-keeping chamber temperature constant below-25 degrees centigrade through evaporation.Then; Partly join from the outlet of the first fresh-keeping chamber evaporimeter 11 first cold-producing medium part that flows out and second cold-producing medium that flows out and flow through check valve 13 from the outlet of the second fresh-keeping chamber evaporimeter 12; Flow through second opening and the 3rd opening of the first return-air heat exchanging segment 15 and the 3rd magnetic valve 9; Flow into refrigerator evaporator 14 then, become gaseous refrigerant, thereby make temperature of refrigerating chamber constant at 2 degrees centigrade～8 degrees centigrade through evaporation.At last, gaseous refrigerant flows out from the inlet of refrigerator evaporator 14, flows through first opening and second opening of second magnetic valve 8, returns compressor 1 then, thereby accomplishes the circulation of cold-producing medium.
