摘要(Abstract):
对以氯化钙-氨为工质对的两床吸附式循环制冷系统进行了实验研究。对实验过程中床内压力、盐水温度的动态变化进行了分析;并研究了热源温度和回质时间对系统制冷性能的影响。研究分析的结果可为改善吸附制冷系统性能及其优化设计提供指导。
An experimental equipment of two-beds adsorption refrigeration cycle using calcium chloride-ammonia pair was established.The change of the pressure in adsorbent beds and brine temperature was obtained experimentally.And also,the effect of heat resource temperature and mass recovery time on adsorption refrigeration capcity and COP was investigated.The results can provide theoretical guidance for system improvement and practical design.
