Abstract:
1. An air conditioner comprising: a compressor for sucking and compressing a refrigerant; an outdoor heat exchanger for effecting heat exchange between a refrigerant and outdoor air; a pressure-reducing means for reducing the pressure of and expanding a high pressure refrigerant; an indoor heat exchanger for effecting heat exchange between a refrigerant and air which is blown into a compartment; an inlet side switching valve for opening and closing a refrigerant path on the refrigerant inlet side of the indoor heat exchanger; and an outlet side switching valve for opening and closing a refrigerant path on the refrigerant outlet side of the indoor heat exchanger; wherein both the switching valves open the refrigerant paths by the use of the pressure produced by the compressor and close the refrigerant paths by the use of the elastic force of elastic means when the compressor comes to a stop.
