There is a peak in IJ1, with some load depending on the weather during the day, and a peak in the evening and night. And by around 24:00, the load will be gone. In this device, if the time period for hot water supply heating operation is set, for example, during the day, there will be approximately 4 to 5 hours of time for hot water supply and heating. Therefore, the hot water storage tank 7 (V) and the boiling water temperature TH"C1 temperature sensor 1 which have been input in advance.

Additionally, if a heating load occurs during this hot water heating time, hot water heating operation is temporarily stopped and heating operation is resumed, but hot water heating operation is resumed during times when there is no heating load, and in total hot water heating is possible. time tp
The hot water tank 7 starts to boil when the water reaches the temperature. Each of the above operation modes is shown in a 70-chart as shown in Fig. 7. If the mode is selected in step S1 and it is the cooling mode, the cooling operation is performed in step S2, and whether it is the heating mode or the hot water supply mode. For example, if there is an out-of-line heating load in step S3, heating operation is performed in step S. If there is no heating load in step S, the process goes to step S5, where the pre-input hot water tank capacity (■Ai) and hot water tank upper capacity (Vl) are entered in advance.
In addition to the upper water temperature of the hot water tank (T1) and the lower water temperature of the hot water storage tank (T2), by setting the hot water heating time in step S6, the water temperature of the hot water tank (T3) can be calculated from the following equation (1) (step S ,)T,=iT,xV,+T2(V-V,)l

きる。In addition, in FIG. 3, two indoor heat exchangers are used, but it goes without saying that three or more indoor heat exchangers can be used. Also,
Instead of the three-way valve 11, two two-way valves may be used to perform the same operation, and the three-way valve 11 may be an electrically operated valve that can adjust the flow rate. Since the hot water supply heating operation is performed at the low frequency of the inverter 17 in this manner, efficiency is high and the peak value of the electric power load that occurs during the hot water supply heating operation can be suppressed.
