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.

Air conditioner

An air conditioning system has an air conditioner, which includes an outdoor unit and an indoor unit that configure a refrigerant circuit, and a controller, which controls the running of the air conditioner. The controller does not allow operation of the air conditioner to start in a case where a signal from a ventilation unit that includes a ventilation fan for ventilation and ventilates a target space or a refrigerant leak sensor that detects refrigerant leakage in the target space is not input to the controller. Because of this, even in a configuration where an air conditioner and a ventilation unit are installed independently of each other, operation of the air conditioner can be performed in a state in which there is reliably established a countermeasure such as the ventilation unit being operated when the refrigerant has leaked, and safety and security with respect to refrigerant leakage are reliably ensured.
