Title:
REFRIGERATION DEVICE, CONTROL METHOD FOR REFRIGERATION DEVICE, AND TEMPERATURE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/163793
Kind Code:
A1
Abstract:
A refrigeration device 10 according to one embodiment opens a liquid bypass control valve 16B when the discharge temperature of a refrigerant before being discharged from a compressor 11 and flowing into a condenser 12 exceeds a threshold value, and closes the liquid bypass control valve 16B when the discharge temperature is less than or equal to the threshold value. Furthermore, the refrigeration device 10 adjusts the rotation speed of the compressor 11 such that evaporation pressure of a refrigerant flowing through a portion of a refrigeration circuit 10A becomes a preset target evaporation pressure, said portion being on the downstream side of an evaporator 14 and an upstream side of the compressor 11, and being on a downstream side of a connection position of a downstream end of a liquid bypass flow path 16A.
