Claims

[Scope of utility model registration request]

It incorporates a supply air blower that takes in outside air, an exhaust blower that exhausts indoor air, and a heat exchanger that is installed adjacent to each of these blowers and exchanges heat between the supply air flow and the exhaust air flow. A high-performance filter is provided between the inlet side of the air supply flow of the heat exchanger and the air supply blower in the main body casing, which has an outside air outlet and an exhaust air intake opening on the lower surface. A supply air bypass is provided on one side of the heat exchanger to bypass the supply air flow path of the heat exchanger, and on the other side of the heat exchanger,
An air conditioning ventilation system characterized in that an exhaust bypass is provided to detour the exhaust flow path of a heat exchanger, and each of these bypasses is provided with a damper that opens and closes the bypass.
