| Summary: | 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. |
