Patent attributes
An air conditioner includes a refrigerant circuit which connects an outdoor circuit and a plurality of indoor circuits connected in parallel. The air conditioner includes a leak detection section which detects leak of a refrigerant from the indoor circuits, and a control section which circulates the refrigerant to perform a refrigeration cycle when the leak detection section detects leak of the refrigerant such that the refrigerant in the indoor circuits of the refrigerant circuit is at a low pressure. Providing the control section in the air conditioner can reduce the leak of the refrigerant from the indoor circuit at low cost.
