Performance and Economic Study of Large-Scale Air-Conditioning System Using Renewable Energy Sources

As a result of the effects of climate change and global warming, air conditioning demand is increasing quickly. Continuous usage of conventional electric air-conditioning with electricity produced by the combustion of fossil fuels would constantly increase of greenhouse gases and significantly worsen global warming. Additionally, demand for air conditioning would keep increasing. Hybrid air conditioning systems provide the potential to save a lot of energy and reduce emissions when compared to traditional air conditioning systems. The thermal analysis of the desiccant wheel, heat exchanger, ground source circulation system, and solar collector for a hybrid air conditioning system is therefore performed in this study, and the system's economic effectiveness is evaluated. The hybrid system is more effective than the vapor compression technique, according to the results. The dynamic investment payback period is about 6 years, based on the results of the economic study, and t the vapor compression system life cycle cost is increasing at a rate that is faster than that of the hybrid air conditioning system. The hybrid system lowers the cooling coil load by 48% as compared to the vapor compression system.
