PURPOSE: A heat pump system is provided to reduce waste of energy and minimize load of compressor, while allowing for effective heat recovery from the waste water and efficient operation of the heat pump system. CONSTITUTION: A heat pump system comprises a hot water supply line for supplying hot water from a roof storage tank(1) to a bathroom(6) through a hot water tank(5); a waste water discharge line for discharging the waste water through a waste heat recovery unit(7); a boiler unit(2) for supplying hot water through the hot water supply line and recovering heat from the waste water through the waste water discharge line; and a heat exchanger connected to the hot water supply line, the waste water discharge line and a compressor. The hot water supply line for connecting the roof storage tank and the hot water tank is equipped with an auxiliary water supply tank(4). The hot water supply line arranged between the auxiliary water supply tank and the roof storage tank is connected to the waste heat recovery unit through a branch pipe(11) and a recovery pipe(12). An auxiliary supply pipe(15) has an end connected to the input side of the heat exchanger and the other end connected to the hot water supply line of the recovery pipe side. The waste water discharge line extended from the waste heat recovery unit is equipped with a waste water tank(3). An evaporative line(38) extended from the heat exchanger of the boiler unit forms an evaporator unit in the waste water tank. A recovery line(39) extended from the evaporator unit is connected to the compressor mounted in the boiler unit. |
