The cooling water that has cooled the main body of the internal combustion engine 1 and has risen in temperature is further heated by the exhaust gas in the third heat exchanger 9. The thus heated cooling water exchanges heat with the water in the hot water storage tank 4 in the second heat exchanger 10, whereby the exhaust heat of the internal combustion engine 1 is recovered as a heating source for hot water supply. The cooling medium drawn out from the second heat exchanger 10 exchanges heat with the medium circulating within the heat pump circuit 2 in the first heat exchanger 11 . Therefore, in the heat pump circuit 2, in addition to the amount of heat pumped up by the evaporator 8, the amount of heat input from the first heat exchanger 11 is radiated from the condenser 6. Therefore, the amount of heat radiated by the condenser 6 is increased and sufficient heating is achieved.

で、内燃機関１を円滑に起動することができる。 In the heating/water supply system configured in this manner, when the internal combustion engine 1 is started, the temperature of the cooling water flowing into the jacket 1a from the first heat exchanger 11 may be too low to cause the internal combustion engine 1 to start smoothly. .
Therefore, the cooling medium circulation circuit 3 includes a bypass pipe line 1 which directly leads the cooling water from the second heat exchanger 10 to the jacket 1a by bypassing the first heat exchanger 11.
5 is provided. A solenoid valve 16 is provided in the middle of this bypass line 15. Further, a solenoid valve 17 is provided downstream of the branch position of the bypass pipe line 15 between the second heat exchanger 10 and the first heat exchanger 11 of the coolant circulation circuit 3 . A temperature detector 18 is provided inside the jacket 1a,
The solenoid valves 16 and 17 are controlled to open and close by the controller 19 in accordance with the temperature value of the cooling water detected by the temperature detector 18 . That is, the jacket 1a
If the temperature of the cooling water inside is equal to or higher than a preset temperature, the solenoid valve 16 is closed and the solenoid valve 17 is opened. Further, when the temperature of the cooling water in the jacket 1a is lower than the set value, the solenoid valve 16 is opened and the solenoid valve 17 is closed. In this way, when starting the internal combustion engine 1, the jacket 1
Since the temperature of the cooling water in the engine a does not drop excessively, the internal combustion engine 1 can be started smoothly.

加熱に利用することができる。 Note that the heat pump circuit 2 can also be operated for cooling as is well known by switching the four-way valve 20. In this case, the solenoid valve 17 is closed and the cooling water from the second heat exchanger 10 is transferred to the bypass pipe 15.
However, if the temperature of the cooling water from the second heat exchanger 10 does not become sufficiently low, cooling may be performed by using a fan 21 or the like shown in phantom line in the middle of the bypass pipe 15. Bye. Furthermore, during this cooling operation, the evaporator 8 of the heat pump circuit 2 functions as a condenser and radiates heat. Therefore, instead of the evaporator 8 as a condenser, a water-cooled heat exchanger 22 as shown by the phantom line is provided, and the water for hot water supply is stored after passing through the water-cooled heat exchanger 22 as shown by the phantom line arrow 23. It may also be supplied to tank 4. In this way, the heat radiated from the heat pump circuit 2 during the cooling operation can be used to heat the hot water supply.

The medium is placed between the evaporator and the compressor during heating operation.
A second medium is introduced into the heat exchanger and a second medium is introduced into the circulation circuit.
Since the heat exchanger is provided to heat the hot water supply, the exhaust heat of the internal combustion engine is used to heat the hot water supply water, and is also used to heat the first medium of the heat pump circuit. Therefore, heating efficiency can be improved.

ことができる点で優れている。 Furthermore, since the main body of the internal combustion engine is cooled by the second medium whose temperature has been sufficiently lowered by the first heat exchanger as described above, overheating of the internal combustion engine main body can be prevented. In particular, this makes it possible to maintain stable operation of the internal combustion engine even when the amount of hot water in the second heat exchanger is small and therefore the second medium is not sufficiently cooled by the hot water. It is excellent in that it can

Since the medium does not pass through the first heat exchanger, it is possible to prevent the temperature of the second medium from becoming too low at the beginning of operation of the internal combustion engine. This allows smooth startup and subsequent operation of the internal combustion engine.
