One main challenge of air-conditioning is the progression of a chiller that consists of natural refrigerants, is environmentally friendly and driven by Renewable Energy. With its’ relatively high latent heat of evaporation, water is one of the main considerations. This report will be dealing with an adsorption cooling system via the heated water of solar panels. However, the vapor compression cycle systems used now are environmentally unfriendly and energy-consuming. This project focuses on (i) the research and understanding of different forms of renewable energy and their sources, (ii) the generation of a MATLAB code to provide the transient formulation of the require outlet water temperature from Photovoltaic Thermal (PV/T) Solar Cells, (iii) the chiller operating conditions of 3 different Zeolite-Water Combination: AQSOA-Z01, AQSOA-Z02 and AQSOA-Z05. Based on the research of Solar Energy, a thermodynamic and mathematical modelling is shown to further understand the working principle of a PV/T Solar Cell and simulate the performance of variable parameters to produce the outlet water temperature. Next, the simulation of the performance parameters of the given adsorption chiller under the various outlet water temperature. The energy and mass balances for every component of the PV/T Solar Cell and adsorption chiller are presented within this report. The performance parameters such as the Specific Cooling Power (SCP), and the Coefficient of Performance (COP) are calculated at various hot water temperatures and cycle times. The simulation results shows that the AQSOA-Z01 has a COP range between 0.65 and 0.85, with a SCP of ~1.3, AQSOA-Z02 has a COP range between 0.29 to 0.4 and a SCP range between 0.35 to 0.79 and, AQSOA-Z05 has a COP range between 0.15 to 0.22 and a SCP of ~0.2.
