Abstract
An air conditioner includes a use-side unit, a heat source-side unit, refrigerant connection pipes, cutoff valve provided in the refrigerant connection pipes, a refrigerant leakage detector, and a controller control. When the refrigerant leakage detector detects a refrigerant leakage, the controller performs pressure reduction control to lower the pressure of the refrigerant in the use-side unit, and thereafter puts the cutoff valves into a cutoff state.
