Document Type and Number:
WIPO Patent Application WO/2023/177092
Kind Code:
A1
Abstract:
A heat pump system according to an aspect of the disclosed invention may comprise: a compressor that compresses a refrigerant; a water heat exchanger in which heat is exchanged between the compressed refrigerant and introduced water; an expansion valve for expanding the refrigerant condensed in the water heat exchanger; an outdoor heat exchanger in which heat is exchanged between the refrigerant expanded by the expansion valve and outdoor air; a high-tension pressure sensor that detects the temperature of the refrigerant to be condensed in the water heat exchanger; a discharged water temperature sensor that detects the temperature of water on which heat exchange has been performed in the water heat exchanger; and a control unit that determines a target condensation temperature of the refrigerant on the basis of a detection result of the discharged water temperature sensor, compares the target condensation temperature with the current condensation temperature detected by the high-tension pressure sensor, and controls the degree of opening of the expansion valve according to the comparison result.
