In the present study, refrigerant noise generated from an air-conditioning unit in operation was characterized as water, sha or gas sound by jury testing and was diagnosed and classified by logistic regression which was performed with objective sound quality parameters. A chi-square test was conducted to find parameters that influenced the probability for refrigerant noise to occur, and with the coefficient for each parameter, the study diagnosed the effects of objective sound quality parameters on the probability of refrigerant noise occurring. The normalization of units was carried out to identify the relative influence of each parameter on the probability of such noise occurring. Further, re-logistic regression was performed with parameters selected by the chi-square test. Probability-based optimal cutoff values were determined for the classification of water, sha and gas sounds. Air-conditioning refrigerant noise was definitely classified by taking into account the logistic regression and cutoffs. New experiments on the generation of refrigerant noise were conducted to validate the logistic regression classification. Data obtained from the experiments was classified at an accuracy level of 93.9 percent.
