Experimental and numerical analysis of multi-disc heat exchanger efficiency in adsorption chillers powered with waste heat

Abstract

The thermally-powered adsorption cooling systems capable to utilize industrial waste heat sources and environmentally friendly refrigerants are an effective way to decrease electricity demand due to cooling. The design of the heat exchanger combined with the sorption bed is crucial to enhance the heat transfer within the bed and in consequence, significantly contributes to the adsorption chiller efficiency. Therefore, the aim of the carried out research was to investigate the possibility of implementing the innovative multi-disc heat exchanger in an adsorption cooling technology. The logarithmic mean temperature difference, as well as temperature distribution within the investigated heat exchanger, were obtained with experimental and numerical research.
