Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an air conditioner in which high pressure control can be carried out efficiently and stably at the time of heating operation. SOLUTION: At the time of heating operation, high temperature high pressure gas refrigerant delivered from a compressor 21 is fed through a four-way valve 23 to an indoor heat exchanger 26. After condensation heat is discharged into a room for heating, a low temperature low pressure gas-liquid phase is generated in an electronic expansion valve 27 and further gasified through a super cooler 25, an outdoor heat exchanger 24 and a double tube heat exchanger 28 to produce gas refrigerant. It is returned back to the compressor 21 through an accumulator 29. Heat exchange between the gas refrigerant and cooling water in the double tube heat exchanger 28 is controlled by the flow rate of cooling water flowing through the double tube heat exchanger 28 thus controlling the pressure of the gas refrigerant delivered from the compressor 21.
