Abstract

PURPOSE: To effectively perform hot water supply, in a hot water supplying and heating apparatus equipped with a solar energy apparatus and a heat pump apparatus, by immediately stopping the hot water supplying and heating operation to be switched to the cooling heat accumulation operation when the water temperature in the heat accumulation tank is elevated to a prescribed temperature during the cooling heat accumulation operation.
CONSTITUTION: The heat pump apparatus 1 and a cooling and heating heat accumulation tank 5 are connected by a cold and hot water circuit 3, and a heat exchanger 11 is arranged in the onward path of the cold and hot water circut 3, and is connected by a hot water circuit 13 to a hot water reservoir 12 for hot water supply by the heat pump. To the cooling and heating heat accumulation tank 5 are connected a plurality of fan and coil units 7, and in the cold and hot water circuit 3 is arranged a three-way valve 10 that is connected to a by-pass line 101. During the cooling operation, when the cold water temperature in the heat accumulation tank 5 is lowered to a prescribed temperature, and the three-way valve 10 is switched to the by-pass line 101 so that the hot water reservoir 12 is heated by the heating operation of the heat pump apparatus 1, if the water temperature in the heat accumulation tank 5 is elevated to a prescribed temperature, the three-way valve 10 should be switched to the heat accumulation tank 5 so that the apparatus 1 performs the cooling operation again.
