HYBRID GEOTHERMAL HEAT PUMP SYSTEM FOR USING HEAT OF WATER HEAT SOURCE

摘要

PURPOSE: A hybrid geothermal cooling and heating system using a water tank as an auxiliary heat source is provided to remarkably reduce installation costs by minimizing the installation of additional structures. CONSTITUTION: A hybrid geothermal cooling and heating system(100) using a water tank as an auxiliary heat source comprises an underground heat exchanger(110), a heat pump(120), a water tank(130), and an underwater heat exchanger(140). The underground heat exchanger has heat transfer liquid for absorbing or emitting heat. The heat pump heat-exchanges with the heat transfer liquid by receiving the heat transfer liquid. The water tank is buried in the ground and stores water. The underwater heat exchanger is installed inside the water tank and has heat transfer liquid. The underwater heat exchanger reduces the load of the underground heat exchanger by supplying the heat transfer liquid to the heat pump.
