Claims

[Claims for Utility Model Registration] A first exhaust passage that exhausts indoor air taken in from the first indoor air intake 29 to the outside from the first exhaust port 33 via the total heat exchanger 23, and a second indoor air intake. A second exhaust passage that exhausts the indoor air taken in from the inlet 52 to the outside from the second exhaust port 34 via the total heat exchanger 23, and the outside air taken in from the first outside air intake port 53 to the total heat exchanger 23. A heat exchanger/ventilation unit 2 having a first air supply passage for supplying air into the room from the first air supply port 35 via the first air supply passage, and switching means 55 and 57 for switching between the second exhaust passage and the first air supply passage.
0 and a fan coil unit 21 having a second air supply passage for supplying outside air taken in from the second outside air intake 43a into the room from the second air intake 46, for ventilation and exhaust heat recovery. Indoor air is exhausted through the first exhaust passage of the heat exchanger/ventilation unit 20, and outside air is taken in through the first air supply passage, and the total heat exchanger 23 exchanges total heat between the exhaust air flow and the supply air flow. When performing ventilation and cooling, use the heat exchanger/ventilation unit 2 mentioned above.
The indoor air is exhausted through the first exhaust passage and the second exhaust passage of 0, and the fan coil unit 21
An air conditioner with a ventilation function, characterized in that outside air is taken in through a second air supply passage.
