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 outside air outlet. A heat exchange element having a laminated structure and a cross-flow type rectangular prism is installed at an angle of approximately 45° between the indoor air inlet and the indoor air inlet. an exhaust blower that forms an exhaust flow that reaches the indoor air outlet through one air passage of the heat exchange element; and an exhaust blower that is incorporated in the intake passage of the outer casing;
an intake blower that forms an intake air flow from the outside air intake port to the outside air discharge port via the other air passage of the heat exchange element; A ceiling characterized by comprising a bypass that is open and connected to the suction side of the exhaust blower of the exhaust passage through a switching damper whose rear end can be opened and closed, and a damper that opens and closes the front part of the exhaust passage. Installed heat exchange ventilation equipment.
