Abstract

An outdoor for an air conditioner according to the exemplary embodiment of the present invention includes: a casing; a compressor installed in the casing and compressing refrigerant; an accumulator installed in the casing and separating liquid refrigerant from refrigerant that flows into the compressor; and a soundproof member absorbing or insulating noise generated while the compressor operates and placed to at least surround the compressor, wherein the soundproof member includes: a first soundproof member absorbing or insulating noise by forming an outer surface of the soundproof member; and a second soundproof member provided in the first soundproof member and absorbing noise in a relatively lower-frequency band than the first soundproof member.

First claim

What is claimed is:

1. An outdoor unit for an air conditioner, comprising:
a casing;
a compressor to compress refrigerant and disposed in the casing;
an accumulator to separate liquid refrigerant from refrigerant that flows into the compressor and disposed in the casing;
a first soundproof member in the casing to surround the compressor and the accumulator, and including a sound absorption section to absorb noise or a sound insulation section to insulate noise generated while the compressor operates; and
a second soundproof member including four sections intersecting the first soundproof member partitioning a space surrounded by the first soundproof member into a first zone where the compressor is positioned, a second zone where the accumulator is positioned, and a third zone and a fourth zone where neither the compressor or accumulator are positioned to absorb noise generated while the compressor operates.

2. The outdoor unit for an air conditioner of claim 1 , wherein the second soundproof member absorbs noise in a lower frequency band than noise in a frequency band absorbed by the sound absorption section or insulated by the sound insulation section.

3. The outdoor unit for an air conditioner of claim 1 , wherein:
the second soundproof member includes a porous fiber material with a plurality of minute holes and planar outer surfaces, and
a plurality of holes that penetrates in a thickness direction of the second soundproof member are formed in the second soundproof member.

4. The outdoor unit for an air conditioner of claim 1 , wherein a first longest distance between the first soundproof member and the second soundproof member in a direction perpendicular to the second soundproof member in the first zone is equal to or more than a second longest distance between the first soundproof member and the second soundproof member in a direction perpendicular to the second soundproof member in the second zone.
