2. Description of the Related Art A conventional air-conditioning ventilator is disclosed, for example, in Japanese Patent No. 88-10622 of the Technical Bulletin published by the Institute of Invention and Innovation. Basically, a box-shaped main body incorporates a heat exchange element as a functional component and a blower for air supply and exhaust, and puts these functional components in a functional state in the main body to form an air supply ventilation passage and exhaust. The ventilation passages are formed independently in all the passages. In the main body, each inlet and outlet of the air supply ventilation passage and the exhaust air ventilation passage is provided as a connection port capable of connecting a duct, and outside air is sucked into the air supply ventilation passage through the duct,
It is supplied from the connection port to the room through the duct. Indoor air is also sucked into the exhaust ventilation passage through the duct, and is exhausted to the outside through the duct from the connection port. The air supply and exhaust streams are heat-exchanged while passing through the heat exchange elements built into the main body, and the heat of the exhaust stream is recovered, so that the cooling and heating load with less fluctuation in the state quantity can be reduced. Ventilation is to be implemented.
