Abstract
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.
