PROBLEM TO BE SOLVED: To eliminate the concentration of stress on a piping connection part and a U-shaped piping folded part and hence improve reliability of the piping connection part by fixing a four-way valve to a body of a compressor, and disposing the four-way valve at a corner of a body of an outdoor unit. SOLUTION: An accumulator 21 to which a piping is connected and is left behind as it is disposed on one part extending in a heat exchange chamber 101 on a vibration plate 103, and a compressor 19 to which a piping is connected and left behind as it is disposed on the other part 103b extending in a machine chamber 102. A four-way valve 22 is fixed to a body of the compressor 19 through a support plate 24. More specifically, the four-way valve 22 is disposed together with the compressor 19 and the accumulator 21 on the one vibration plate 103, and the four-way valve 22 is disposed at a corner of a body 5a of an outdoor unit 5. Hereby, stress concentration on a piping connection part and a U-shaped piping folder part is eliminated and hence reliability of the piping connection part is improved. |
