Current applications of the traditional vapor-compression refrigeration system are not feasible. Space cooling and refrigeration systems that employ vapor-compression refrigeration cycles utilize harmful refrigerants, produce large amounts of carbon dioxide, and have high energy consumption. Adsorption cooling technology is seen as a possible alternative to traditional vapor-compression refrigeration systems. The low-grade heat requirement and eco-friendly adsorbent and refrigerant materials make adsorption cooling an attractive technology. Adsorption cooling technology employs the adsorption principle—the phenomenon in which an adsorbate fluid adheres to the surfaces and micropores of an adsorbent solid. The purpose of this study was to explore the adsorption cooling process through the use of a prototype adsorption test bed design. A basic intermittent adsorption cooling cycle was utilized for the test bed design. Several requirements for the design include low-cost, simple fabrication, and capable of holding a vacuum. In this study, an experiment was carried out to analyze the desorption process, in which the original weight of adsorbed water was compared to the weight of the desorbed water. The system pressure was decreased to sub-atmospheric absolute pressure of 16.67 kPa in order to increase the desorption rate and drive the desorption process. A hot water pump provided 81.6 °C hot water to heat the adsorption bed. The desorption process lasted for a duration of 162 minutes. The experiment resulted in 3.60 g (16.04%) of the initial adsorbed water being desorbed during the desorption process. The study demonstrates the potential of adsorption cooling. This paper outlines the design, fabrication, and analysis of a prototype adsorption cooling test bed.
