Installation of Solar Thermal Adsorption Chiller and its Test Bench Performance Analysis

Abstract

This study aims to install a solar thermal-powered adsorption chiller and evaluate its performance by integrating a test bench into the system. Adsorption chillers can utilize low-grade heat sources below 80°C to operate efficiently without using refrigerants causing carbon emissions and global warming. The commercially available Adsorption Chiller of 4.79 Tons capacity was installed, with a flat plate collector and a cooling tower for heat dissipation. Results showed that average cooling ranged from 0.9 kW to 5.32 kW, with a maximum coefficient of performance (COP) of 0.32 when inlet temperature was varied from 50°C to 65°C, respectively and the flow rate varied from 0.23kg/s-0.27kg/s for high temperature and 0.23kg/s to 0.25kg/s for low temperature line. This study highlights the potential for adsorption chillers to exploit untapped heat sources and improve energy efficiency while minimizing environmental impact. The results of this study can contribute to the development of more efficient and sustainable cooling systems, which can be used to mitigate climate change and promote sustainable development.
