Abstract: PURPOSE:To simplify the facilities and to save energy, by providing a bathtab heat exchanger in addition to a hot water reservoir heat exchanger, and forcibly stopping the operation of the hot water reservoir heat exchanger when the bathtab heat exchanger is in operation. CONSTITUTION:When a bathtab-hot water reservoir change-over switch is changed over to the bathtab side, a motor of a compressor 2 is opened while a third electromagnetic valve SV3 and a bathtab electromagnetic valve SVB are driven by an electric control circuit, so that a refrigerant is circulated from the compressor 2 as shown by broken arrows through the bathtab heat exchanger 26 and an indoor heat exchanger 1 thereby cooling the room as well as further heating a bathtab 13. In this case, a forcibly stopping circuit (not shown) is actuated to retain the hot water reservoir electromagnetic valve SVA at the closed state so that the supply of the refrigerant to the hot water reservoir heat exchanger 15 is cut off. In the case of operation for heating the hot water reservoir, the refrigerant is flowed as shown by solid arrows. According to this arrangement, additional heating of the bathtab can be performed effectively, and the running cost can be reduced.
