Air conditioning compressor sound attenuation

A method of forming a sound attenuator around a compressor of an air conditioning system, the method comprising:

• providing a molding cover, the molding cover having one or more openings configured to receive a pipe;
• positioning a compressor of an air conditioning system in a cavity of the molding cover;
• inserting one or more pipes through the one or more openings of the molding cover;
• attaching the one or more pipes to one or more ports of the compressor;
• covering the compressor with a flexible protective cover;
• placing a first material in the cavity of the molding cover;
• and
• placing a second material in contact with the first material in the cavity of the molding cover,
• wherein the second material chemically reacts with the first material to form a self-forming foam around the compressor,
• wherein the self-forming foam pushes the flexible protective cover inwardly toward the compressor to reduce voids located between the flexible protective cover and the compressor, and
• wherein the one or more pipes are attached to the one or more ports of the compressor before placing the second material in contact with the first material.

A compressor assembly of an air conditioning unit, comprising:

• an air conditioning unit compressor;
• a flexible protective cover covering the air conditioning unit compressor;
• and
• a self-forming foam formed around the air conditioning unit compressor, the self-forming foam being formed by placing a first material inside a removable molding cover proximate the flexible protective cover and placing a second material in contact with the first material, the second material being configured to chemically react with the first material to form the self-forming foam around the air conditioning unit compressor,
• wherein the self-forming foam is:
• (1) separated from the air conditioning unit compressor by the flexible protective cover, (2) configured to push the flexible protective cover inwardly toward the air conditioning unit compressor to reduce voids located between the flexible protective cover and the air conditioning unit compressor, and (3) configured to attenuate a sound produced by the air conditioning unit compressor, and
• wherein a refrigerant pipe is connected to the air conditioning unit compressor by first forming an aperture through the self-forming foam to access a refrigerant port of the air conditioning unit compressor.
