PURPOSE:To make it possible to utilize underground water for air conditioning or space heating as well as to carry out heat pump type air conditioning by providing a system in which heat of underground water can be transferred selectively to a heat storage tank, an indoor heat exchager or a warm-up tank through an underground water heat exchage tank, heat pump, and tank for heat collection and radiation. CONSTITUTION:In addition to heat collected by a solar heat collector, space heating can be made through a heat exchanger 1c and an indoor heat exchanger E by additional heat obtained as follows: heat of underground water is transferred to and stored at the heat storage tank D from an underground water heat exchange tank A through a heat pump B, tank for heat collection and radiation C and heat exchanger 1b with valve 4a-4j opened or closed as specified respectively. For room cooling, heat of underground water is transfereed from the underground water heat exchange tank A to the heat pump B, tank for heat collection and radiation C, indoor heat exchange E and warm-up tank G with the valves 4a-4j operated. In case of room cooling process with no underground water heat being used, heat stored in the tank for heat collection and radiation C is transferred to the warm-up tank G by the heat pump B to reduce temperature of the tank for heat collection and radiation C for room cooling. By this setup, it is possible to utilize underground water for air conditioning and also effect heat pump type air conditioning. |
