Abstract Sustainable future and green environment goals quest for the development of technologies to utilize renewable energy resources to power the people. In this study, an absorption solar air conditioning system has been designed, modeled and simulated. Key performance parameters are pointed, optimized for maximum efficiency and simulated in transient energy simulation software TRNSYS. The designed model comprises three thermal loops: a solar loop consisting of a glass tube solar collector having R-410A as heat transfer fluid in it and a heat exchanger heat tank, an absorption chiller, and an auxiliary furnace with hot water stream, and a cooling tower loop. It also has an air loop for the delivery of colling to each room. The system is simulated Pakistan's climate conditions and offered a good tendency for the proposed system to meet air conditioning demand at the domestic level for weather conditions of Lahore, Pakistan. The average collector outlet temperature value of 78◦C has been recorded throughout the month. Collector provides useful energy gain at an average rate of 71065 kJ/hr. The Outlet water leaves the chiller at an average temperature value of 125◦C. The outlet air temperature from the cooling coil fluctuates between -24 ◦C to 24◦C.
