Claims

[Scope of utility model registration request]

An indoor suction inlet and an indoor air outlet are formed facing the indoor side of the main body outer frame, and an outdoor air inlet and an outdoor air outlet are formed facing the outdoor side, and the indoor air inlet and the outdoor air outlet are communicated with each other and the air is exhausted. An exhaust ventilation passage provided with a ventilation fan and an air supply ventilation passage that communicates the outdoor suction port with the indoor air outlet and provided with an air supply fan are partially intersected and other parts are separated from each other. In a ventilation system in which a heat exchanger is provided at the intersection of the exhaust ventilation passage and the supply air passage, an electrical collector in the supply air passage between the indoor air outlet and the heat exchanger is provided. A lighting room is provided, which is equipped with a dust container and has a lighting device inside facing the indoor side of the outer frame of the main body, and the lighting room communicates with the outdoor air outlet through an outdoor bypass air passage, and is connected to the indoor air outlet. A ventilation system, characterized in that the ventilator communicates with the indoor side bypass air path and switches between the outdoor side bypass air path and the indoor side bypass air path using a switching valve.
