PREDICTION OF EFFECT OF REFRIGERATION SYSTEM PARAMETERS ON THE PERFORMANCE OF A VAPOUR COMPRESSION REFRIGERATION SYSTEM USING DESIGN OF EXPERIMENTS

The aim of the present work is to study the effects of refrigeration system parameters namely, Evaporating temperature (Teva), Condensing temperature (Tcon) and mass of the refrigerant charge used (m), on the performance of the system using mathematical models. Three factors and two levels factorial technique were employed for the development of mathematical models to conduct the required experiments. Based on these mathematical models developed for predicting the values of responses, the effect of individual system variables and their significant interaction effects on responses were calculated using MINITAB software. The direct effect of the system variables on the performance was calculated and plotted graphically for the refrigerants R290/R600, R290/R600a, and LPG. The graphs plotted with the help of mathematical models provide satisfactory explanations about the effect of system variables on performance.
