Experimental investigation of the effects of different refrigerants used in the refrigeration system on compressor vibrations and noise

Vibration and noise are undesirable effects in daily life energy-consuming systems. In this study, the of different refrigerants on vibration a sealed reciprocating compressor discussed. The study compared performances with lower ozone depletion potential (ODP) values to R22, which has high ODP value. was carried out experimentally two stages. Firstly, tests were conducted for coefficient performance (COP) refrigerants. Secondly, data obtained results from experiments showed that both COP value have R22 refrigerant other alternative refrigerants, but close obtained. It observed vary depending type used refrigerant. Average determined as 0.604 m/s2 0.603 R438A, 0.593 R417A, 0.622 R422D 0.637 R422A. When examined, it measured 61.327 dB 62.913 62.187 63.715 64.913 99% similar an found 4.07 3.98 3.63 3.37 R422D, 3.18 R438A showing 95% similarity can be R22. Generally, very each all examined.
