PROBLEM TO BE SOLVED: To provide a hot water amount increase method, and also to provide a hot water supply system by a CO2 heat pump compatibly attaining the cooling of a cooler gas provided for cooling a high-temperature and high-pressure refrigerant, and overheat prevention of lubricating oil, in a compressor by parallel forming the gas cooler in an oil cooler provided in the compressor and forming a hot water supply line in a CO2 supercritical refrigeration cycle.;SOLUTION: This hot water supply system provided in the CO2 heat pump is constituted of: the CO2 supercritical refrigeration cycle 15 comprising the compressor 10, the oil cooler 13, the gas cooler 11, an expansion valve 14, and a vaporizer 12; the hot water supply line 20 including a water supply cooling part 16 taking out hot heat by the gas cooler 11 and the oil cooler 13 and controlling the supply water temperature; and a cold heat source 19 obtained from the vaporizer 12.;COPYRIGHT: (C)2003,JPO
