PROBLEM TO BE SOLVED: To perform a pressure balance by a refrigerating cycle enclosing non-azeotrope refrigerant and using a temperature expansion valve as a pressure-reducing device. SOLUTION: An air conditioner successively provides communication among a compressor 1, an outdoor heat exchanger 3, a temperature expansion valves 4, 5 and an indoor heat exchanger 6, and has a refrigerating cycle enclosing non-azeotrope refrigerant for refrigerant. Heating devices 8, 9 are fitted to the temperature-sensing tubes 4a, 5a of the temperature expansion valves 4, 5, and the heating devices 8, 9 are energized at a predetermined capacity for the appropriate time at the same time with the stop of the compressor 1. Thereby, the temperature expansion valves 4, 5 are brought into their open conditions, so that the pressure balance between high pressure and low pressure is performed. Then, the compressor 1 is easily restarted.
