Résumé

In this work, an energy analysis of vapor compression refrigeration system (VCRS) using R134a and LPG refrigerant mixture as an alternative to R134a is carried out. Performance tests were performed with different evaporator and condenser temperatures under controlled ambient conditions. The results showed that R134a and LPG refrigerant mixture has higher coefficient of performance than R134a by about 15.1–17.82%. Mathematical and ANFIS models validated by experimental data were developed to predict the energetic performance of VCRS. It was found that mathematical and ANFIS models predictions agreed well with experimental results and brought out the absolute fraction of variance in range of (0.9253–0.9567 and 0.9953–0.9961), root mean square error in range of (0.0167–7.688 and 0.0018–1.025) and mean absolute percentage error in range of (0.606–2.243 % and 0.103–0.362 %) respectively. The results suggest that ANFIS models show better statistical prediction efficiency.
