Claims

[Scope of utility model registration request]

The interior of the rear side is divided into an upper exhaust passage and a lower intake passage by a shielding plate, and the rear has an indoor air discharge port communicating with the exhaust passage and an outside air intake port communicating with the intake passage. The part includes a flat box-shaped outer casing that is installed along the ceiling surface and has an outside air outlet and an indoor air intake, and a front end of the exhaust passage and the intake passage in the outer casing, and the outside air outlet and the front end of the exhaust passage and the intake passage. A heat exchange element having a laminated structure and a cross-flow type rectangular prism is installed at an angle of approximately 45 degrees between the indoor air inlet and the indoor air inlet. an exhaust blower that forms an exhaust flow that passes through one air passage of the heat exchange element and reaches the indoor air outlet, and is incorporated in the intake passage of the outer casing;
A ceiling installation comprising an intake blower that forms an intake air flow from the outside air intake port to the outside air outlet via the other air passage of the heat exchange element, and an air filter attached to each air inflow side of the heat exchange element. In the type heat exchange ventilation system, the heat exchange element is assembled across the indoor air inlet so that both of its air inflow sides face the indoor air inlet, and the outside air inflow side faces the indoor air inlet. In contrast, the air filter is closed with a shielding plate that can be engaged and detached or opened and closed, and the edge of the air filter is held by the shielding plate, so that the air filter can be attached and removed from the indoor air intake port by opening the shielding plate. A ceiling-mounted heat exchange ventilation system featuring:
