Below with reference to Fig. 1, describe according to the refrigeration system 100 for refrigerator of the utility model first aspect embodiment.Wherein, comprise refrigerating chamber, refrigerating chamber and temperature-changing chamber according to the refrigerator of the utility model embodiment.
As shown in Figure 1, refrigeration system 100 comprises compressor 10, condenser 20, capillary module and evaporator assemblies.Wherein, cold-producing medium flows clockwise by direction as shown, and cold-producing medium constantly circulates in refrigeration system 100, there is gaseous state and liquid phase transformation variation, and carry out exchange heat with the external world, flow into the liquid evaporation heat absorption in evaporimeter, thereby play Temperature drop in refrigerator effect.Wherein, the entrance 201 of condenser 20 and the outlet 101 of compressor 10 are connected.Can also comprise device for drying and filtering, reservoir and anti-condensation pipe etc. according to the refrigeration system 100 of the utility model embodiment, those of ordinary skills are known, are not described in detail here.
Particularly, capillary module comprises the first capillary 41, the second capillary 42, three capillary 43 and the 4th capillary 44.The entrance of the first capillary 41, the second capillary 42, three capillary 43 and the 4th capillary 44 is all connected with the outlet 202 of condenser 20.Evaporator assemblies comprises refrigeration evaporator 31, the first alternating temperature evaporimeter 32, the second alternating temperature evaporimeter 33 and refrigerating evaporator 34.
Refrigerating evaporator 34 is for freezing to refrigerating chamber, the entrance 341 of refrigerating evaporator 34 is connected with the outlet of the 4th capillary 43 with the outlet 312 of refrigeration evaporator 31, the outlet 332 of the second alternating temperature evaporimeter 33 respectively, and the outlet 342 of refrigerating evaporator 34 is connected with the entrance of compressor 10.
That is to say, cold-producing medium after the first capillary 41 throttlings can flow through refrigeration evaporator 31 and refrigerating evaporator 34 successively, that is to say, cold-producing medium after the first capillary 41 throttlings evaporates at refrigeration evaporator 31, to refrigerating chamber carried out cooling after, not evaporating completely liquid refrigerant can flow to refrigerating evaporator 34 and further evaporate, not only can make thus unnecessary liquid refrigerant fully evaporate, and by the adjusting of the first capillary 41, can make the temperature control of refrigeration evaporator 31 more accurate.
