REFRIGERATION CYCLE DEVICE

WIPO Patent Application WO/2015/194107

A1

This refrigeration cycle device comprises: a low temperature side pump (11) which takes in and discharges a low temperature side heat carrier; a compressor (21) which takes in, compresses, and discharges a refrigerant; a heat dissipating unit (15) which dissipates heat from high-pressure refrigerant discharged from the compressor (21); a pressure reducing device (23c) which reduces the pressure of the high-pressure refrigerant for which the heat has been dissipated by the heat dissipating unit (15); an internal heat exchanger (24) which exchanges heat between the high-pressure refrigerant flowing from the heat dissipating unit (15) and low-pressure refrigerant discharged from a heat carrier cooling unit (14); a low-pressure refrigerant temperature sensing unit (23a) which detects or senses the temperature associated with the temperature of the low-pressure refrigerant that exchanged heat in the internal heat exchanger (24); and an overheating control unit (23b) which controls the degree of overheating of the low-pressure refrigerant that exchanged heat in the internal heat exchanger (24) on the basis of the temperature detected or sensed by the low-pressure refrigerant temperature sensing unit (23a).
