The study attempts to optimize the parameters for LiBr –water absorption refrigeration system using Taguchi. The investigation was carried out to optimize the Coefficient of Performance (COP) for heat removal of 100W. The three factors considered were: Generator Temperature (Tg), Condenser Temperature (Tc), Absorber Temperature (Ta), Evaporator Temperature (Te). at three different levels. The L9 orthogonal array was selected and the best optimum conditions were identified based on Signal to Noise (S/N ratio) ratio, under the clause: larger is the best. The results showed generator temperature contribution is more on COP.
