GEOTHERMAL HEAT EXCHANGE SYSTEM

摘要

PURPOSE: A geothermal heat exchange system is provided to accomplish an improved effectiveness of heating/cooling at a reduced cost without causing environmental pollution. CONSTITUTION: A system comprises a geothermal heat exchanger(1) for circulating subterranean heat, ground water, or a subterranean heat of a predetermined temperature existing in an open water area, a cooling cycle and a heating cycle for circulating the subterranean heat drawn out to the ground by the geothermal heat exchanger, and an indoor hot water cycle connected to the heating cycle and which heats indoor water. Thus, subterranean heat having a predetermined temperature is effectively drawn out to the ground and used for a heating/cooling system, to thereby reduce cost for energy.
