Title:
REFRIGERATION DEVICE, REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/079242
Kind Code:
A1
Abstract:
A condensing unit (3) is provided with: a compressor (31) which compresses a refrigerant; a gas cooler (32) which condenses the refrigerant compressed in the compressor (31); an electronic expansion valve (33) which expands the refrigerant condensed in the gas cooler (32); and a controller (100) which adjusts the degree of opening of the electronic expansion valve (33) such that the pressure of the refrigerant compressed by the compressor (31) approaches a target high-pressure value set on the basis of the outside air temperature, and which corrects the target high-pressure value if the opening degree of the electronic expansion valve (33) exceeds a predetermined opening upper limit value or opening lower limit value.
