Application of CFD methods in heat transfer analysis of adsorption cooling and desalination system

Popis výsledku v původním jazyce

Rapid climate changes force the reduction of fossil fuel consumption in favor of renewable energy sources like solar power, wind energy, waste heat, and heat produced in cogeneration. Adsorption and absorption chillers are seen as an opportunity to significantly reduce the conventional electricity consumption to power energyintensive air conditioning and other efrigeration systems. However, the most impediment to disseminating these technologies is the low efficiency of sorption refrigeration systems currently available on the market. Therefore, the main objective of this study was to build a numerical model of an adsorption bed using computational fluid dynamics (CFD) methods, which were used to analyze and optimize heat transport within the bed. Based on this research, an effective engineering tool was developed to simulate the operation of the adsorption bed utilized for preliminary verification of the efficiency of innovative heat exchanger designs that allow for improved efficiency of the entire sorption system. This approach allows only pre-optimized configurations to be selected for conducting expensive and long-lasting experimental research, which must precede the industrial implementation of new types of dsorption beds. The used CFD approach makes it possible to reduce the time of development and introduction to the market of environmentally friendly adsorption chillers with improved efficiency.
