<p>PURPOSE: A ground heat pump system using rainwater is provided to enable the rainwater to be used as heavy water and the heat source of a heat pump. CONSTITUTION: A ground heat pump system using rainwater comprises a heat pump(100), a geothermy heat exchanger(123), a first circulating line(121), a rainwater heat exchanger(127), a rainwater tank(130), and a second circulating line(129). The geothermy heat exchanger is buried underground. The first circulating line connects the geothermy heat exchanger to a first heat exchanger and circulates the heat transfer medium. The rainwater heat exchanger is connected to a branched pipe(125) branched from the first circulating line and the heat transfer medium flows along the branched pipe. The second circulating line connects the rainwater heat exchanger to the rainwater tank and circulates the rainwater filled in the rainwater tank. A hot water line is connected to the rainwater heat exchanger, the heat transfer medium and the rainwater circulating the rainwater heat exchanger heat-exchanges with the hot water circulating the hot water line, the branched pipe and the hot water line are connected to a geothermy bypass circuit and the heat transfer medium bypasses the rainwater heat exchanger.</p> |
