Claims

[Scope of utility model registration request]

In the cavity of the weather cover of the simultaneous supply/exhaust ventilation system, in contact with the back cover of the weather cover, an exhaust reservoir and an air supply reservoir, as well as a heat exchange box with a sound insulating function that is appropriately in contact with both, are arranged in an appropriate manner. , outside air enters the air supply reservoir from the air supply port on the front of the weather cover through the air supply passage in the heat exchange box, and is supplied into the room through the air supply pipe connected to the air supply reservoir, in the opposite direction. Indoor air passes through the exhaust pipe, enters the exhaust sump connected to the end of the exhaust pipe, then passes through the exhaust passage of the heat exchange box and is exhausted outdoors through the exhaust port under the front of the weather cover. , a weather cover that blocks the leakage of indoor sound and the intrusion of outdoor sound when supplying and exhausting air at the same time, and also enables heat exchange between the supply and exhaust.
