ShareNOISE SOURCE IDENTIFICATION IN SEMI-HERMETIC TWIN-SCREW COMPRESSORS.
Author(s) : ANDREWS R. W., JONES J. D.
Summary
A FULLY-CONDENSING LOAD STAND WAS DESIGNED TO ALLOW THE 70 TON (246 KILOWATTS) CHILLER SYSTEM TO BE OPERATED AT THE THREE-STANDARD LOADING CAPACITIES OF THE COMPRESSOR. THE LOAD STAND WAS OPERATOR CONTROLLED AND WAS USED TO VARY INDIVIDUAL COMPRESSOR OPERATING PARAMETERS FOR SENSITIVITY STUDIES. THE TWO-MICROPHONE CROSS-SPECTRAL INTENSITY TECHNIQUE WAS USED TO EVALUATE THE RADIATED SOUND FIELD FOR A VARIETY OF COMPRESSOR OPERATING CONDITIONS.
