<P>PROBLEM TO BE SOLVED: To restrain degradation of sound absorbing performance caused by water-absorption of a sound isolation material. <P>SOLUTION: An outdoor unit 10 includes a compressor 22 for compressing a refrigerant in a refrigerant circuit 20, a first sound isolation material 3A containing a sound absorbing material 41 having water absorbability and a sound insulation material 42 and covering a side surface of the compressor 22, and a bottom plate frame 16 on which the compressor 22 is installed. The first sound isolation material 3A includes an upper side sound absorbing material 41a and a lower side sound absorbing material 41b arranged in the vertical direction as the sound absorbing material 41, and is provided with a water interception part 43 for blocking movement of water sucked from above a bottom plate 17a of the bottom plate frame 16 by the lower side sound absorbing material 41b from the lower side sound absorbing material 41b to the upper side sound absorbing material 41a, between the upper side sound absorbing material 41a and the lower side sound absorbing material 41b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
