An air conditioning device comprises: a plurality of shut-off devices that are each disposed between an indoor unit and a plurality of heat source devices and that shut-off the flow of refrigerant flowing in refrigerant pipes; a plurality of leak detecting units that detect refrigerant leaks from each heat source device; and a controlling device that controls the operation of the plurality of heat source devices, the indoor unit, and the shut-off devices. The controlling device comprises: a shut-off controlling unit that operates the shut-off device connected to the heat source device from which refrigerant is leaking when a refrigerant leak is detected by the leak detecting unit; a capacity setting unit that, when shut-off devices in an operating state and shut-off devices in an non-operating state are present among the plurality of shut-off devices, sets a heat exchange capacity limit for the indoor unit when a heat source device connected to a shut-off device in the non-operating state is operated; and an operation controlling unit that controls the operation of the heat source devices or the indoor unit using the heat exchange capacity limit set by the capacity setting unit as the upper limit. |
