SIMULATION, DEVELOPMENT AND PERFORMANCE EVALUATION OF A SOLAR GAS HYBRID POWERED ABSORPTION AIR CONDITIONING SYSTEM

📄 Project Abstract

In this study, a gas assisted solar powered absorption air - conditioning system was designed, constructed and tested under Zaria weather conditions in Nigeria. A technical and economic viability study of the system was first carried out by developing and simulating a TRNSYS model of the system to cool an office block with an average space cooling demand of 151.8kWh/m2 per annum, under Zaria weather conditions. System components were sized and optimized to give maximum coefficient of performance (COP), solar coefficient of performance (SCOP) and solar fraction (SF). Design of the optimised system components was done through a programming based design, optimisation and performance evaluation method using MATLAB. A reduced size version of the system, which includes a 4 kW absorption chiller prototype was constructed. Experimental tests were conducted on the constructed system. The experiments were carried out on a test room in the months of April and June 2017. The experimental days were...
