Experimental investigation on solar-powered ejector refrigeration system integrated with different concentrators
2021
The objective of the work is to analyse and to improve the efficiency of solar-powered ejector refrigeration system integrated with flat-plate collector and Scheffler concentrator. The Scheffler concentrator of 2.7 m² and flat-plate collector of 5 m² collecting area are coupled with the storage tank of 15 l capacity. The developed system was designed for a potential replacement of conventional 1-ton room air conditioner with much reduced electrical energy consumption. The system was built based on two key subsystems namely ‘Scheffler concentrator-based vapour system’ and ‘ejector-based cooling system’. The pilot effort showed promising results with the probability of energy-saving potential as near 70 to 80% over conventional air conditioners.
