Analytical study of a solar hybrid air-conditioning system assisted solar absorption using R-410A for refrigeration applications

Abstract

This research focuses on the design, modeling, and simulation of absorption solar air-conditioning systems. Key performance parameters are identified and optimized for maximum efficiency, and the system was simulated using climatic conditions in Thi-Qar, Iraq, providing a good trend for the system to meet domestic air-conditioning needs, which has a direct effect on the angle of incidence of solar radiation. The results of solar collectors and their effective performance in saving energy and improving system efficiency were discussed, where the work was performed on a solar heater with an evacuated tube with an area of 1.8_m2. The rate of emitted solar radiation was equal to 1000_W/m2. The average heat load of the solar heater was provided at a rate of 0.190 to 1.291_kW. The experiment in this paper was conducted in two stages. First, the solar heater was connected in the first case before the compressor. The reported results showed an increase in energy savings with average heater temperatures rising to 25
