Claims

[Scope of utility model registration request]

The supply air is supplied from the casing body through the heat exchanger by the rotation of the supply fan, while the supply air flows into the casing body from the damper operated by the rotation of the exhaust fan and is exhausted. In a ventilation system that performs air supply and exhaust at the same time, an air passage is provided above the heat exchanger for supplying air, and the rear opening of this air passage is closed by a damper when opened, creating a short circuit between the supply air and exhaust air. Ventilation device characterized by eliminating the effect.
