Problems solved by technology

[0003] The object of the present invention is to aim at the deficiencies of the prior art, and design and provide a bypass double-cycle refrigerator with a variable evaporation area of ​​the evaporator in the refrigerating room, which overcomes the shortcomings of the inaccurate temperature control of the dual-temperature refrigerator in the existing design, and is also more efficient than the evaporator. Series refrigerators and existing bypass double-circulation refrigerators are more energy-efficient

Abstract

Disclosed is a bypass dual loop refrigerator which has alterably evaporator vaporizing area of the cold-storage case, comprising main circular loop and by pass loop. The main circular loop comprises compressor, condenser, drying filter, three way electromagnetic valve, master capillary, refrigeration evaporator, cold storage evaporator, liquid tank. The bypass circular loop comprises compressor, condenser, drying filter, three way, electromagnetic valve, bypass capillary, cold storage evaporator, storage tank. And the cold-storage case evaporator vaporizing area of the main circular is different from that of bypass loop. The present invention could control effectively and independently temperature of every cold storage case insure temperature of the cold storage case to fluctuate within small range, enhance fresh keeping characteristic of the refrigerator.

Description

Technical field: [0001] The invention relates to a double-cycle refrigerator, in particular to a bypass double-cycle refrigerator with a variable evaporation area of ​​an evaporator in a refrigerating chamber, which is used for food storage and preservation, and belongs to the technical field of refrigeration. Background technique: [0002] The earliest direct-cooling dual-temperature refrigerators were designed as evaporators in series (single circulation loop). The series structure can only control the temperature of one refrigerating chamber, usually the temperature of the refrigerating chamber, while the temperature of the freezing chamber is determined by the size of the evaporator area of ​​the freezing chamber. This structure will lead to inaccurate temperature control of the freezer, large thermodynamic irreversible loss of the evaporator in the cold reduction chamber, and at the same time, when the ambient temperature is low, the refrigerator needs electric heating ...
