Most previous studies on adsorption chillers were conducted using the same adsorption and desorption times. Instead, this study analyzed various adsorption/desorption time allocations, and systematically examined the effect of cycle time allocation on system performance. The results provide physical insights for 3-bed adsorption chillers. The effect of hot water temperature and cycle time on the optimum adsorption/desorption time ratio was also examined. Setting the proper adsorption and desorption times was much more important for smaller cycle times. The highest degradation in COP (coefficient of performance) found was 36 % at 300 s of cycle time, compared with the conventional 1:1 ratio. When the temperature of the heat source is low, the ratio of adsorption/desorption time was not significantly affected, however, for higher performance at high temperature, a longer adsorption time than desorption time was required.

吸附和解吸循环时间分配对吸附式冷却器性能的影响

以前大多数有关吸附冷却器的研究都是使用相同的吸附和解吸时间进行的。相反,本研究分析了各种吸附/解吸时间分配,并系统地检查了循环时间分配对系统性能的影响。结果为3床吸附式制冷机提供了物理见解。还研究了热水温度和循环时间对最佳吸附/解吸时间比的影响。对于较短的循环时间,设置适当的吸附和解吸时间更为重要。与传统的1:1比率相比,在300 s的循环时间中,发现的COP(性能系数)的最高降低为36%。当热源的温度低时,吸附/解吸时间的比率没有受到显着影响,但是,
