An air conditioning system (110) has a coolant circuit (120) in which are connected an outdoor circuit (111a) and a plurality of indoor circuits (112a) connected in parallel to one another. The air conditioning apparatus (110) has a leak detection unit (141) for detecting leakage of coolant from an indoor circuit (112a), and a controller (142) that, in event that coolant leakage is detected by the leak detection unit (141), circulates the coolant so that the refrigeration cycle takes place in such a way as to bring the coolant in the indoor circuit (112a) of the coolant circuit (120) to low pressure. By furnishing the air conditioning system (110) with this controller (142), coolant leakage from indoor circuits can be minimized at low cost. |
