In an air conditioning/heating/hot water supply system having such a structure, when heating 1.2 rooms or more (operating 2 or more indoor units), a high-pressure tan drive source, such as engine speed control and refrigerant supplementation, is used in combination. However, if the indoor unit is operated in a single room, heating the refrigerant will result in too large a heating capacity, and the high pressure will rise even when the engine is running at the lowest speed, causing the As shown, the O of the refrigerant heater
There is no choice but to perform N-OFF control. As a result, H
During IM/room operation, high pressure cycles in a short period of time, and the engine speed also fluctuates accordingly, which may lead to engine stalling in some cases. In general, the output characteristics of an engine are such that the lower the rotation speed, the lower the shaft torque, so overload operation in the low rotation speed range is not preferable.

Therefore, in this embodiment, the engine/high pressure detection sensor 26 or the low specific pressure detection sensor 27
The rotation speed control means 2g receives a signal from the rotation speed control means 2g, which controls the rotation speed so that the high pressure or the low pressure in the air conditioning circuit X is maintained at a predetermined value. That is, during heating operation, the discharge specific force of the pressure wI machine is detected by the high pressure pressure detection sensor 2.
When the pressure is detected by B and the pressure is below the set pressure, the rotation speed control means 2 outputs a speed increase signal to the actuator, opens the throttle valve, increases the engine speed to 4th speed, and conversely increases the pressure above the set pressure. If so, perform the opposite operation to the above to reduce the engine speed. Also, during cooling operation, the suction method of the compressor is detected, and if the fa constant pressure is exceeded, the speed is increased, and if the pressure is below the set pressure, the speed is decelerated.

Next, like during the daytime at home, / when driving,
That is, when one of the in-mold heat exchangers S, S, and S is in operation, the on-off valve 29 is closed to stop the supply of high-pressure liquid refrigerant to the refrigerant heater 10, and at the same time, the on-off valve 21I is closed.
is opened, a part of the gas refrigerant discharged from the compressor 2 is bypassed to the suction side of the gas pump //, and the function of the gas pump // is stopped. Therefore, in the heating and cooling circuit X, heating operation is performed using only the heat pump capacity, and the rotational speed of the engine is controlled to be around the rated rotational speed by the rotational speed control means 2g. As a result, most of the exhaust heat from the engine is transferred to the heat medium hot water heater.
It can be turned to 7, leading to improved hot water supply capacity. Furthermore, not only is the operating state of the engine always stable, but the exhaust heat from the engine is also greater than that at the lowest rotational speed in the conventional example, and the hot water supply capacity is increased.
