AN AIR-CONDITIONING SYSTEM USING GEOTHERMAL AND CHILL IN ICE STORAGE

摘要

PPROBLEM TO BE SOLVED: To provide a heating and cooling system allowing simultaneous operations for heating and cooling, using a geothermal source, capable of carrying out simultaneously or separately the cooling operation and the heating operation. PSOLUTION: A heating and cooling working fluid flowing in a cooling pipe 130 connected respectively to an evaporator 110 of a heat pump 100 and a condenser 120 and flowing in a heating pipe 140 is heat-exchanged with a working fluid in the heat pump 100 to be transmitted simultaneously to a cooling heat exchanger 152 and a heating heat exchanger 154 respectively, and a desired space is cooled or heated thereby. Of course, the cooling operation by the cooling and heating working fluid flowing in the cooling pipe 130 and the heating operation by the cooling and heating working fluid flowing in heating pipe 140 are selectively carried out.
