固体吸附式制冷系统制冷剂的解吸特性
Refrigerant desorption characteristics in solid adsorption refrigeration system
摘要
Abstract
A single-bed adsorption refrigeration experimental system with the working-pair of activated carbon-methyl alcohol was built. And investigations on the effect of desorption temperature and desorption time on the desorption amount of refrigerant in cylindrical adsorption tube were conducted. The desorption temperature was set at 84, 89 and 94℃, and the desorption was last for 4, 5, 6 and 7 h, respectively. The experimental results indicate that desorption temperature, desorption time and the desorption amount of refrigerant had significant effect on the refrigeration recycling performance of the adsorption refrigeration system. The minimum coefficient of performance (COP) of 0.053 was achieved when the heating resource temperature was maintained at 84℃ and the heating time was 4 h. The maximum COP of 0.19 was achieved when the desorption temperature was maintained at 94℃ and desorption time was 6 h. Consequently, 94℃ and 6 h were recommended as the optimal desorption temperature and desorption time. If the desorption time was continuously increased to be more than 6 h, the increasing rate of desorption amount would be less than that of energy consumption, then COP will consequently decrease.关键词
