Abstract: This paper represents design and performance evaluation with experiments tests of solar-biogas powered hybrid vapour absorption refrigeration system. The system designed for 40 liter capacity with 0.05 TR for cooling Amonia- water mixtures. This refrigerator system was designed 140°C temperature for generator by heating source like solar energy and biogas flame. Biogas flame as heat source was produced more than 140°C temperature and COP of the system achieved 0.134 individually. When system whole day working with biogas flame. Solar energy which was used 4 to 5 hours daily when solar radiation was available. In this case when solar thermal as heat source was produced only 70°C temperature but in the case of solar panel direct current supply to heater, heater as a heat source was produced approximately 150°C temperature. In case hybrid powered when 18 hours using biogas flame as heat source and 4 to 6 hours hour solar energy in the form of solar panel DC supply, COP had achieved 0.1.
Keywords: Biogas flame as heat source was produced more than 140°C temperature and COP of the system achieved 0.134 individually.
