Parametric Study of a Solar Heat Driven Silica Gel–Water Paired Adsorption Chiller
Abstract: Heat driven sorption based cooling systems are gaining interest as they are environmentally friendly and have the potential to save precious fossil fuel resources. Low grade thermal sources like solar or waste heat can run a silica gel-water paired adsorption chiller to generate chilled water below 10°C. However, the performance of the adsorption chillers is poor when compared to vapour absorption or vapour compression based cooling systems. An effort has …
