し、貯湯運転が終了する。 Next, the operation will be explained. FIGS. 2 and 3 are electrical connection diagrams and operation pattern diagrams regarding this device. First, the hot water storage operation pattern will be explained. In FIG. 2, if the operation switch (not shown) of the heat pump chiller unit 1 is turned on,
The relay contact 25PX-a of the relay (not shown) on the chiller unit 1 side is closed, the coil 25P of the electromagnetic contactor for the heat source primary pump 6 is energized, and the heat source primary pump 6 starts operating. At this time, the first program timer coil PT1 for setting the hot water storage operation and air conditioning operation time, and the water supply solenoid valve 16
Coil PT2 of the second program timer for setting the water supply time and coil PT3 of the third program timer for setting the operation time of the hot water pump 20
is energized. 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 While being energized, the hot water tank 11
When the water temperature inside the pump 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 , its contacts
XQ- 1 , XQ- 2 and XQ- 3 are each reversed from the b side to the a side, and the coil of the first solenoid valve 6
MV 1 is instantaneously energized, the first solenoid valve 6 is opened, and 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, passes through the first solenoid valve 6 and the flow resistance adjustment valve 8. , is led to the hot water supply heat exchanger 3, passes through the heat source primary pump 9, and returns to the heat pump chiller unit 1. Note that when contact X Q -2 of relay coil ), and the second solenoid valve coil MV2 is energized, so the second solenoid valve 7 is opened together with the first solenoid valve 6 for a predetermined period of time (for example, 10 seconds). After that, the circuit will be closed. On the other hand, in the hot water supply circuit 12, the hot water passes through the heat source secondary pump 13 from inside the hot water storage tank 11, exchanges heat with the hot water supplied from the chiller unit 1 in the hot water heat exchanger 3, and is heated up.
Return to When the water temperature in the hot water tank 11 reaches a predetermined value, the temperature detector 22 is activated and the contact 23 is activated.
W is opened, the operation of the heat source secondary pump 13 is stopped, and the hot water storage operation is completed.

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-2 , and X Q-3 of the relay coil X Q return from the a side to the b side. For this reason, the relay coil 2-1 opens its time-limited contact 2-1-b after a predetermined time (for example, 10 seconds), and contrary to the above, the first solenoid valve coil MV 1 is delayed and de-energized. , the first solenoid valve 2 is closed, the second solenoid valve coil MV 2 is instantaneously energized, the second solenoid valve 3 is opened, and the heat source side primary pump 9 is connected to the relay contact 52PX-a and Operate via relay contact X Q - 1 . 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 return to chiller unit 1.
This is a well-known air conditioning circuit based on the water cooling and heating system.

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 1), the contacts (not shown) of the parallel-connected relay coils XQ are 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 XQ is deenergized by the first program timer as described above, and the contact point (not shown) of the relay coil ) is opened, 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-limiting contact PT3-a is closed, relay coil X 3 is energized, and relay coil X 2
Since the electromagnetic contactor 52PJ of the hot water supply pump 20 is energized through the contact X 2 -b, 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 the relay contact X1-a is closed. At this time, if the hot water in the hot water tank 11 is in an intermediate state (from level E1 to level E2 in FIG. 1), the level detector 21 detects this and outputs a signal.
In order to close the contact R- a , the relay coil Water will be supplied. At this time, contact X2-b of relay coil X2 is opened, so coil 5 of the magnetic contactor of hot water pump 20 is opened.
2PJ is deenergized, and the operation of the hot water supply pump 20 is reliably stopped. When the hot water tank 11 becomes full of water (level E1 in Figure 1), the level detector 21 detects this and outputs a signal.
The contact R-a is opened, the water supply solenoid valve 16 is closed, and the water supply is stopped.

level), the level detector 21 detects this and outputs a signal, so the contact R-a
is closed, relay coil X2 is energized, and its contact X2-b is opened, so hot water pump 20
The coil 52PJ of the electromagnetic contactor is deenergized and the hot water supply pump 20 stops operating. That is, since the E2 level detection end of the level detector 21 is located above the inlet portion 18a of the hot water supply circuit 18, the hot water supply pump 2
No air is trapped at 0.

Furthermore, the second program timer allows hot water to be supplied during air conditioning operation.

せることを防止することができる。 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, when the hot water level in the hot water tank drops below a predetermined level, the control circuit for the hot water pump is opened and the hot water pump is deactivated and interlocked, so that the water in the hot water tank is not in a dry state. It is possible to prevent the hot water supply pump from causing air trapping and causing hot water supply failure.
