For example, in the above embodiment, the air conditioning indoor unit connected to the air conditioning outdoor unit 300 via the first pipe P1 and the second pipe P2 may be further included.

In this case, a flow rate detector may be added that is turned off when the ventilator 200 is in the non-blowing state to stop the heater from heating.
In the above embodiment, when the second heat exchanger 150 is omitted, the third refrigerant pipe port D3, the regulator valve 142, and the third pipe P3 may be omitted at the same time, that is, the air conditioning outdoor unit 300 having a two-pipe structure may be used.
In the above embodiment, the ventilator 200 has the total heat exchanger 240, but the ventilator is not limited to this, and the total heat exchanger 240 may be omitted.
