配設されている。In such a split-type air conditioner, a thin through duct is provided in the partition wall so that the indoor air cooled or heated by the indoor unit does not leak outside, and the indoor unit and the outdoor unit are connected inside this through duct. A refrigerant pipe is provided to connect the two.
ところが、このような空気調和装置を有する部屋におい
て、煙草の煙、臭気等の不清浄空気が存在した場合、こ
の不清浄空気を換気する必要がある。However, if unclean air such as cigarette smoke or odor is present in a room equipped with such an air conditioner, it is necessary to ventilate the unclean air.
このような不清浄空気を換気するため、この種スブリッ
し形の空気調和装置では、室内機を取付けた隔壁に近接
して室内機とは独立に換気用風送機が取付けられ、室外
空気と室内空気との換気が行われている。In order to ventilate such unclean air, in this type of sub-type air conditioner, a ventilation fan is installed independently of the indoor unit, close to the bulkhead where the indoor unit is installed, and is connected to the outdoor air. Ventilation with indoor air is provided.
そのため、隔壁には空気調和装置の冷媒配管用の貫通ダ
