AIR CONDITIONER

To provide an air conditioner using a combustible refrigerant having specific gravity larger than air, and capable of using a standard circular hole as a construction hole of a building so as to quickly perform construction without a reinforcement material for the building by forcibly exhausting air inside an indoor unit to the outdoors, and ensuring high safety.SOLUTION: An air conditioner of this invention including an indoor unit having at least an indoor blower and an indoor heat exchanger uses a combustible refrigerant having specific gravity larger than air, and includes a suction exhaust device for sucking and exhausting air inside the indoor unit, a suction duct communicated with the suction exhaust device, an exhaust duct for exhausting air from the suction exhaust device to the outdoors, and ventilation control means for performing constant ventilation with the usage of the suction exhaust device.SELECTED DRAWING: Figure 1 【課題】本開示は、空気より比重の大きい可燃性冷媒を用いた空気調和機において、室内機内部の空気を強制的に屋外に排気することで、建屋の施工穴を標準的な丸穴とし建屋への補強材なしに迅速に施工できる安全性の高い空気調和機を提供する。【解決手段】本開示における空気調和機は、少なくとも室内送風機と室内熱交換器を有する室内機を備える空気調和機であって、空気より比重の大きい可燃性を有する冷媒を用い、前記室内機内部の空気を吸引排気する吸引排気装置と、前記吸引排気装置に連通する吸込ダクトと、前記吸引排気装置から室外へ排気する排気ダクトと、前記吸引排気装置を用いて常時換気を行う換気制御手段を備えた。【選択図】図１
