PROBLEM TO BE SOLVED: To prevent flammable refrigerant from standing at a dangerous place upon leakage by performing external exhaustion and discharging the atmosphere to a safety place. SOLUTION: A sensor 8 is disposed on the indoor side and a discharge motor valve 9 is disposed on the outdoor side. In the air conditioner, refrigerant compressed by a compressor 1 radiates heat in an outdoor heat exchanger 3 and passes, in liquefied state, through a dryer 4 and a throttle valve 5 to produce low temperature gas-liquid mixture refrigerant which is vaporized in an indoor heat exchanger 6 by absorbing heat before being supplied to the compressor 1. A gas sensor 8 delivers a refrigerant discharge signal to the discharge motor valve 9 immediately upon detecting leakage of propane gas to open the valve 9 thus discharging propane gas in the retrigeration cycle to the atmosphere thus preventing flammable refrigerant from standing at a dangerous place. |
