摘要： An air conditioner selection system is a system for selecting an air conditioner including an indoor unit. The air conditioner selection system is provided with a floor area acquisition section, an allowable refrigerant amount acquisition section, and an air conditioner selection section. The floor area acquisition section acquires a floor area of a room where the indoor unit is to be installed. The allowable refrigerant amount acquisition section acquires an allowable refrigerant amount of a refrigerant allowed to remain in the room at least based on the floor area acquired by the floor area acquisition section. The air conditioner selection section selects the air conditioner including the indoor unit installable in the room at least based on the allowable refrigerant amount acquired by the allowable refrigerant amount acquisition section.

摘要： An air conditioner includes a plurality of indoor units of a refrigerant circuit to perform air conditioning of a space, and an air conditioning controller that controls operations of the plurality of indoor units by allocating the indoor units individually to a plurality of predetermined areas of the space. The controller performs an area registration process of allocating the indoor units individually to a plurality of area identification frames corresponding to the areas, and allocating a plurality of ventilators individually to the area identification frames where the indoor units are allocated. The ventilators perform ventilation of the space. The controller does not allow the operations of the plurality of the indoor units when there is an area identification frame to which none of the ventilators is allocated, in the plurality of area identification frames where the indoor units are allocated.
