Description

  The present invention relates to a compressor mounting device that prevents noise and vibration of a bathroom ventilation air conditioner that constitutes a refrigeration cycle and is equipped with a compressor.

  As shown in FIG. 11, the refrigerant in the conventional refrigeration cycle is discharged from the compressor 101, the discharge pipe 102, the first heat exchanger 103, the flow control valve 104, the second heat exchanger 105, the suction pipe 106, and an accumulator (not shown). To the compressor 101, and the above configuration completes the refrigeration cycle. The compressor 101 is attached by fixing the compressor 101 to the bottom plate 107 to which the compressor 101 is attached with bolts 108 and nuts 109, and fixing between the compressor 101 and the bottom plate 107 through vibration-proof rubber 109.

  Further, a soundproof cover 110 made of felt is wound around the compressor 101 and the accumulator (see, for example, Patent Documents 1 and 2).

  When the compressor 101 is operated, noise and vibration are generated from the compressor 101, especially when the compressor 101 is started and stopped, the vibration is large, and the vibration of the compressor 101 is absorbed by the anti-vibration rubber 109. The vibration transmitted to the discharge pipe 102 and the suction pipe 106 connected to the pipe is reduced, the pipe stress is reduced, and the pipe is prevented from being broken.

However, depending on the installation of the compressor 101 and the operating state, the vibration is large, the vibration is transmitted from the foot 111 of the compressor 101 to the bottom plate 107, exceeds the allowable range of the anti-vibration rubber 109, and the anti-vibration effect is reduced. In the soundproof cover 110, the sound leaks out, but the vibration becomes a vibration sound and goes out of the product.
