Title:
REFRIGERATION CYCLE DEVICE AND AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/047830
Kind Code:
A1
Abstract:
This refrigeration cycle device has a refrigeration circuit that connects a compressor, a condenser, an expansion valve, and an evaporator via piping and circulates a mixed refrigerant that has a temperature gradient. The refrigeration cycle device comprises a two-phase pipe temperature sensor that detects a heat exchanger passage temperature for the mixed refrigerant that passes through the condenser, a heat exchanger opening temperature sensor that detects the temperature of the mixed refrigerant that flows out of the condenser, and a control device that determines a correction value for a degree of subcooling that is the difference between the heat exchanger passage temperature detected by the two-phase pipe temperature sensor and the heat exchanger opening temperature detected by the heat exchanger opening temperature sensor, corrects the degree of subcooling, determines whether to perform subcooling control on the basis of the corrected degree of subcooling, and performs subcooling control on the basis of the determination.
