HIGH EFFICIENCY HEAT PUMP HEATING AND COOLING DEVICE USING VENTILATION WASTE HEAT/HEAT STORAGE MATERIAL

摘要

PPROBLEM TO BE SOLVED: To perform cooling operation in summer and to make up for heat source shortage separately in addition to ventilation air capacity in the case of heating operation in winter and furthermore to improve an operating effect with extremely high efficiency. PSOLUTION: A system for attaining the function of heating operation of a heat pump is constituted by installing a second water heat exchanger 5, utilizing a heat storage material tank 7 as a sub-heat source for the heat source shortage in using the ventilation air capacity for a house as a heat source, and leading in hot water as a heat source from a heat storage material. The heat pump is operated with high efficiency throughout the year, and energy consumption can be reduced. PCOPYRIGHT: (C)2007,JPO&INPIT
