First, the hot water storage operation pattern will be explained. In FIG. 2, when the operation switch (not shown) of the heat pump chiller unit 1 is turned on, the relay contact 52PX-a of the relay (not shown) on the chiller unit 1 side is closed, and the electromagnetic coil for the heat source primary pump 6 is closed. The contactor coil 52P is energized, and the heat source primary pump 6 operates. Also, at this time, the first
The program timer coil PT1, the second program timer coil PT2 for setting the water supply time of the water supply solenoid valve 16, and the third program timer coil PT3 for setting the operation time of the hot water supply pump 20 are energized. 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
through the hot water supply heat exchanger 3, and then through the heat source primary pump 9 to the heat pump chiller unit 1.
Return to In addition, when contact X Q -2 of relay coil X Q switches from side b to side a, relay coil 2
-2 is energized, its time limit contact 2-2-b is closed until a predetermined period of time (for example, 10 seconds) has elapsed, and the second solenoid valve coil MV2 is energized.
The second solenoid valve 7 is opened together with the first solenoid valve 6 for a predetermined period of time (for example, 10 seconds), and then closed. On the other hand, in the hot water supply water circuit 12, the heat source secondary pump 1 is
3, heat exchanges with the hot water supplied from the chiller unit 1 in the hot water heat exchanger 3, and raises the temperature.
Return to hot water tank 11. And hot water tank 11
When the internal water temperature reaches a predetermined value, the temperature detector 22 is activated, the contact 23W is opened, and the heat source secondary pump 1 is activated.
The operation of step 3 is stopped and the hot water storage operation is completed.

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. For this reason,
By the relay coil 2-1, the time-limited contact 2-1
-b opens after a predetermined time (for example, 10 seconds), so contrary to the above, the first solenoid valve coil MV 1 is delayed and deenergized, the first solenoid valve 2 is closed, and the second
The solenoid valve coil MV 2 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
to drive through. Therefore, in the water circuit 2, cold water or hot water from the chiller unit 1 passes through the second solenoid valve 7, is guided to the fan coil unit 5, cools or heats the room, and then is sent to the heat source primary pump. 9 and returns to the chiller unit 1, forming a so-called well-known cooling/heating water type air conditioning circuit.

クルのまゝである。 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, contact PTI-a of coil PT1 of the first program timer
When the relay coil X Q is opened, the relay coil ), the heat pump chiller unit 1 can be 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 However, since the four-way valve (not shown) is energized via the heating/cooling switch (not shown), the heat pump chiller unit 1 remains in the heating cycle.

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.
