Abstract

This paper is the second part of a study on the use of adsorption refrigeration cycles driven by waste heat of near-ambient temperature. Experiments were conducted with several heat transfer fluid operating temperatures (hot, cooling, and chilled water), flow rates, and adsorption-desorption cycle times, and good qualitative agreement was obtained with the simulated results. Both experiments and simulation showed that the silica gel-water adsorption cycle is well suited to near-environmental-temperature heat sources and small regenerating temperature lifts, which help reduce the heat losses intrinsic to batched cycle operation. The chiller was operational with a hot water inlet temperature (Thot in) of 50°C (122°F), and the highest experimental values of the coefficient of performance (COP) (more than 0.4) were obtained with Thot in = 50°C (122°F) in combination with cooling water at 20°C (68°F).
