Claims

[Scope of utility model registration request]

A part of the liquid refrigerant on the outlet side of the condenser of the main refrigeration system is transferred between the auxiliary expansion valve and the main refrigeration system, which is constructed by sequentially connecting the main compressor, condenser, expansion valve, and evaporator. A refrigeration system configured by connecting an auxiliary refrigeration system constituted by an intermediate heat exchanger that subcools liquid refrigerant and an auxiliary compressor connected to the discharge side of a main compressor, wherein the main refrigeration system includes the above-mentioned The evaporator of the main refrigeration system is divided into a first cooler that flows high-pressure supercooled liquid refrigerant before and after the expansion valve, and a second cooler that flows liquid refrigerant after depressurization, which are housed in the same refrigerator. refrigeration equipment.
