機２で空１ｉＩ（冷房）に利用される。To explain the operation of the air conditioner configured in this way, when the main operation is cooling, the heat source device 1 is operated to produce cold water of about 4 to 15 degrees Celsius for cooling, and the heat source water piping 3 is operated. Pass it through. In each air conditioning unit 2, when the air conditioning request is for cooling, the temperature level matches the temperature level of the heat source water, so the air conditioner 2 is operated as follows. The cold water of the heat source is pipe 1.
1 to the water heat exchanger 4, the refrigerant in the water heat exchanger 4 is cooled and condensed, and the cold water is passed from the pipe 12 to the return path 3' of the heat source water.
Return to. The condensed refrigerant passes through the pipe 13, the bypass pipe 21, the valve 10, and the pipe 14 and reaches the air heat exchanger 5 due to the movement of the pump 22. In the air heat exchanger 5, the refrigerant absorbs heat from the air to become steam, passes through the pipe 15, the valve 9, and the bypass pipe 20, and reaches the water heat exchanger, forming a circulation cycle. The air that has been cooled by removing heat from the air heat exchanger 5 is used for air cooling by the blower 2.

作用する）に至る。If the air conditioning request is for heating, it does not match the temperature level of the heat source water. In this case, the compressor of the heat pump is operated, and first, cold water from the return path 3' of the heat source water is introduced into the water heat exchanger 4 (acting as an evaporator) through the pipe 16, heat is removed from the cold water, and the refrigerant is evaporated, and the cold water is returned from the pipe 11 to the outgoing path 3 of the heat source water. The evaporated refrigerant is transferred to the pipe 18, the switching valve 8,
It passes through a pipe 19, is compressed by a compressor, and then passes through a pipe 16 and a switching valve 8.
, pipe 17, and pipe 15 to the air heat exchanger 5 (acting as an N condenser).

The air heated by releasing heat from the air heat exchanger 5 is
The air blower 2 provides heating.

空気が暖房用に供される。On the other hand, when the main operation is heating and the air conditioning request is heating, the air conditioning requests match, so the beat pump compressor does not operate, and the operation is opposite to that for cooling. That is, hot water is introduced from the heat source water 3 into the water heat exchanger 4 through the pipe 11, and the refrigerant is evaporated by the hot water. By the operation of the pump 22, the refrigerant vapor reaches the air heat exchanger 5, releases heat to the air and condenses, and the condensed refrigerant passes through the pan bath pipe 20 and circulates to the water heat exchanger 4, forming a cycle. The air heated by the air heat exchanger 5 is used for heating.

That is, the water heat exchanger 4 functions as a condenser and releases heat from the pipe 12 to the heat source water, and the refrigerant is condensed, passes through the pipe 17, the throttle device 7, and the pipe 14, and is transferred to the air heat exchanger. 5 (acts as an evaporator), heat is removed from the air, the refrigerant evaporates, and pipe 1
5, passes through the pipe 17, the switching valve 8, and the pipe 16, and reaches the compressor;
