(Revised 2nd edition) P.168) Problems to be Solved by the Invention In the conventional cooling and heating method, the contaminated air generated in the room cannot be discharged, and a separate ventilation device is provided for ventilation. Was needed. However, simply ventilating it will increase the heating and cooling load. Further, if the ventilation device and the cooling / heating device are simply integrated, the device becomes large, a large space for installation is required, and there are many restrictions on the installation. In addition, when the return air from a toilet or a living room where cigarette smoke is generated is mixed in the air conditioner, the smell or smoke diffuses into each room, which sometimes causes discomfort. In addition, these odors and smoke stain the inside of the air supply duct 102, and there is a problem that discomfort increases as time passes.

The present invention solves the above-mentioned conventional problems, and can perform cooling and heating while discharging polluted air generated indoors, and can prevent an increase in the cooling and heating load, and further, requires a large space for installation. There are few restrictions on installation, and it is possible to combine ventilation in the living room where toilets that emit odors and smoke of cigarettes generate smoke. An object of the present invention is to provide a ventilation air conditioner capable of preventing odor and smoke from clinging to the air supply duct to each room.
