NOISE REDUTION STRUCTURE OF MULTI AIR CONDITIONER

摘要

A structure for preventing transfer of compressor noises of a multi-type air conditioner is provided to divide refrigerant into dozens of small masses by installing a muffler where a perforated plate is installed on a refrigerant pipe. A structure for preventing transfer of compressor noises of a multi-type air conditioner includes a muffler(100). The muffler has a perforated plate(110) inside of the muffler to divide refrigerant into dozens of small masses on a refrigerant pipe(15). Both end sides of the muffler have the same diameter as the refrigerant pipe. A center of the muffler has a bigger diameter than the refrigerant pipe. The perforated plate is installed in a direction of blocking the flow of the refrigerant on a center of the muffler. A plurality of small through holes is installed on the perforated plate. The total sum of areas of the through holes has to be bigger than a cross section of the refrigerant pipe.
