Title: Outdoor unit for air conditioner
Inventor: KOBAYASHI TOSHIHIKO
IPC: F24F1/40
Filed: 2020-09-17
Abstract: To provide a safe outdoor unit for an air conditioner with reduced noise.SOLUTION: In an outdoor unit for an air conditioner in the present disclosure, a compressor is covered with a compressor soundproof material and an outer periphery of a four-way valve 13 is also surrounded by a four-way valve soundproof material 16 for sound insulation. A lower portion of the four-way valve soundproof material 16 surrounding the outer periphery of the four-way valve 13, which opposes to an electric three-way valve 14, is configured to have a bag shape. Since this configuration can prevent leakage of not only noise generated in the compressor but also collision noise of a refrigerant flow generated in the four-way valve 13 to outside, the sound insulation effects can be enhanced and noise reduction can be promoted more effectively. Even if dew condensation water is generated on the outer periphery of the four-way valve 13 and the dew condensation water forms droplets, the droplets are received by the bag-shaped portion of the lower portion of the soundproof material. Thus, a situation where the dew condensation water adheres to a coil of the three-way valve, etc. can be prevented, so as to enable the outdoor unit for the air conditioner to exhibit higher safety.SELECTED DRAWING: Figure 3
