Claims

[Scope of utility model registration request]

An air supply passageway having a first intake port that draws in outdoor air from an air supply port by an air supply blower and distributes a supply air flow to be blown indoors from an air outlet and communicates with the interior of the room, and a second intake port by an exhaust blower. The exhaust passage has an exhaust passage through which the exhaust air is sucked in from the indoor air and is blown out to the outside from the exhaust port, and two passages are independent and intersect with each other. The passage includes a heat exchanger through which the exhaust flow flows, an electrostatic precipitator filter installed in the air supply passage and which charges and adsorbs dust particles in the air by applying a DC high voltage, and the air supply opening;
The first air intake port and the second air intake port are provided in a first state, the air supply port and the second air intake port are opened and the first air intake port is closed, and in the second state, the air supply port and the second air intake port are closed. a damper that closes two intake ports and opens the first intake port.
