Abstract (en)
An air-conditioning apparatus 100 that includes a refrigeration cycle in which a compressor 10, a heat-source side heat exchanger 12, an expansion unit 16, and a load-side heat exchanger 15 are included and are connected with refrigerant pipes, includes cutoff units 37 and 38 capable of flowing or cut off a refrigerant circulating in the refrigeration cycle; a detection unit detecting leaking of the refrigerant on the basis of a resistance that changes with densities of plural kinds of leaked refrigerants; a concentration calculation unit 41 calculating a concentration of a refrigerant that has leaked, on the basis of the resistance of the detection unit; a concentration detection unit 39 outputting a calculation result of the concentration calculation unit 41 in order that the calculation result is used for controlling the cutoff units 37 and 38; and a cutoff control unit 40 controlling the cutoff units 37 and 38 on the basis of an output of the concentration detection unit 39.
