There is. Next, when the operation switch SW-1 of the heat exchange unit 14 is turned on, the time limit contact PT1-a of the first program timer is closed and the relay coil When energized and the water temperature in the hot water tank 11 is below a predetermined value, the contact 23W of the temperature detector 22 is closed, so the coil 52PQ of the electromagnetic contactor for the secondary heat source pump 13 is energized. Also, due to the energization of relay coil X Q ,
The contacts X Q -1, X Q -2 and X Q -3 are respectively reversed from the b side to the a side, and the coil MV 1 of the first solenoid valve 6 is instantly energized and the first solenoid Valve 6
is opened, the coil MV 2 of the second solenoid valve 7 is deenergized with a delay, the second solenoid valve 7 is closed, and the heat source primary pump 9 continues to operate. Therefore, regarding the water circuit 2, since the heat pump chiller unit 1 is in the heating cycle, hot water is supplied from the chiller unit 1 to the water circuit 2, and the first solenoid valve 6 and the flow resistance adjustment valve 8

路となる。 Next, the air conditioning operation pattern will be explained. When the air conditioning operation time begins, the coil PT1 of the first program timer is activated, and its time-limiting contact PT1-
Since a is opened, the coil 52PQ of the magnetic contactor
is deenergized, the heat source secondary pump 13 stops operating, and the contacts X Q −1, X Q − of the relay coil X Q are deenergized.
2 and X Q -3 return from side a to side b. Therefore, the time-limiting contact 2-1 is connected by the relay coil 2-1.
-b opens after a predetermined time (for example, 10 seconds), so contrary to the above, the first solenoid valve coil MV1 is delayed and deenergized, the first solenoid valve 2 is closed, and the second
The solenoid valve coil MV2 is instantly energized and the second
The solenoid valve 3 opens and the heat source side primary pump 9
is relay contact 52PX-a and relay contact X Q -1

のまゝである。 The heat pump type chiller unit 1 is located at the cooling side contact during the summer cooling season to deenergize the four-way valve (not shown) for switching the cooling/heating cycle, and during the winter heating season it is located at the heating side contact to deenergize the cooling/heating cycle switching four-way valve (not shown). It has a manual air-conditioning/heating selector switch (not shown) that energizes a four-way valve (not shown). Therefore, when transitioning from hot water storage operation to cooling operation, the relay coil A contact (not shown) of a relay coil XQ connected in parallel (not shown) is opened, the four-way valve (not shown) is deenergized, and the heat pump chiller unit 1 is switched from the heating cycle to the cooling cycle. In addition, when transitioning from hot water storage operation to heating operation, the relay coil X Q is deenergized by the first program timer as described above, and the contact of the relay coil (not shown) opens, but since the four-way valve (not shown) is energized via the air conditioning/heating selector switch (not shown),
The heat pump chiller unit 1 remains in the heating cycle.

PT3 is activated, its time-limited contact PT3-3 is closed, relay coil X 3 is energized, and the relay coil
Since the electromagnetic contactor 52PJ of the hot water supply pump 20 is energized via the contact X 2 -b of X 2 , the hot water supply pump 20 is operated. Therefore, the heated hot water in the hot water tank 11 can be supplied from the hot water tap 19.

Since the water supply time period is set by the second program timer, when that time period comes, the coil PT2 of the second program timer is activated, its time limit contact PT2-a is closed, and the relay coil 1 is energized, and relay contact X 1 -a is closed. At this time, if the hot water in the hot water tank 11 is in an intermediate state (from the E1 level to the E2 level in FIG. 1), the level detector 21 detects this, outputs a signal, and connects the contact R. -Relay coil to close a
X 2 is energized and closes its contact X 2 -a, so the coil MV3 of the water supply solenoid valve 16 is energized,
The water supply solenoid valve 16 is opened and water is supplied.
At this time, since the contact X 2 -b of the relay coil X 2 is opened, the coil 52PJ of the electromagnetic contactor of the hot water supply pump 20 is deenergized, and the operation of the hot water supply pump 20 is reliably stopped. When the water supply tank 11 becomes full of water (level E1 in Fig. 1), the level detector 21 detects this and outputs a signal, opening the contact R-a and starting the water supply.

に防止できる。 As described above, in this invention, since the first program timer separates the hot water storage operation zone and the air conditioning operation zone, the hot water storage operation can be performed, for example, when the air conditioning load is small during the day and air conditioning is not required. Furthermore, the second program timer allows hot water to be supplied during air conditioning operation. Therefore, the operating efficiency of the heat pump type chilling unit is increased, and efficient cooling, heating, and hot water supply can be performed. Furthermore, since water is supplied into the hot water tank after the hot water supply operation by the second program timer, high temperature hot water can be supplied during hot water supply, and low temperature hot water is not supplied to the hot water supply area. In addition, at the start of the water supply operation period by the second program timer, the control circuit for the hot water supply pump is opened and the hot water supply pump is interlocked to be inoperable, which may result in an error in the time setting of the third program timer. , and even in the event of a failure, it is possible to reliably prevent low-temperature hot water supply from being supplied to the hot water supply area.
