(Edition) P, 16B) Problems to be Solved by the Invention With the conventional heating and cooling methods described above, it is not possible to exhaust the contaminated air generated indoors, and it is necessary to provide a separate ventilation device for ventilation. Ta. However, simply providing ventilation will lead to an increase in the heating and cooling load. Furthermore, if the ventilation system and the air conditioning system were simply integrated, the system would be large and would require a large space for installation, resulting in many restrictions on installation. ! In addition, when the air conditioner was mixed with return air from smelly toilets or cigarette smoke from the living room, the smell and smoke would spread into each room, often causing discomfort. In addition, these odors and smoke permeate into the air supply duct 1o2, causing a problem of increasing discomfort as time passes.

The present invention solves the above-mentioned conventional problems. It can perform heating and cooling while discharging contaminated air generated indoors, and can prevent an increase in the heating and cooling load. Moreover, it requires a large space for installation. There are no restrictions on installation, and you can also ventilate areas such as toilets where odors are generated or living rooms where cigarette smoke is generated.Furthermore, the odors and smoke do not spread into each room.
