Claims

[Scope of Claim for Utility Model Registration] (1) An indoor suction port and an indoor discharge port that communicate with the indoor space; an outdoor suction port that communicates with the outdoors and that consists of a grid and an opening; and an outdoor discharge port that communicates with the outdoors and consists of a grid and an opening; An exhaust ventilation passage connecting the indoor suction port and the outdoor discharge port and provided with an exhaust blower consisting of a motor, exhaust vanes, and an exhaust orifice, and connecting the outdoor suction port to the indoor side. Connecting the discharge ports, the motor is formed so as to intersect with an intake air passage provided with an intake blower consisting of an intake vane and an intake orifice, and a portion where the exhaust air passage and the supply air air passage intersect is formed. A heat exchanger is disposed, and an exhaust shutter for opening and closing a heat exchanger outlet provided between the heat exchanger in the exhaust air passage and the outdoor outlet, an outdoor intake inlet of the air supply air passage, and the An air conditioning ventilation fan equipped with an air supply shutter that opens and closes between the air supply orifices of the air supply blower. (2) The air conditioning ventilation fan according to claim 1, wherein the inclination angle of the exhaust shutter and the air supply shutter when opened is approximately equal to the inclination angle of the grid of the outdoor suction port and the grid of the outdoor discharge port.
