NOISE REDUCTION TECHNIQUES IN THE SCREW CHILLER

Abstract
Abstract - Screw chiller plants are important constituents of any medium or large-scale manufacturing industry hence evaluating its performance at certain intervals is vital for its proper functioning. Screw compressors generate a substantial level of noise during operation. The first stage in reducing it is to identify and minimize its noise level. To design a low noise screw chiller using the following solutions such as around screw compressor provide acoustic insulation, Perforated discharge Flange, bearing box, liquid injection method, Discharge line Muffler from these techniques noise reduction of screw chiller up to 10.8dba when chiller noise is 78.2. which is comfortable for human hearing and reduces noise pollution.
