摘要

建立了基于吸附-再吸附原理和内部回热技术的双效双重热化学吸附制冷实验系统，对其可行性及工作性能进行了实验研究。测试结果表明：双效双重热化学吸附制冷热力循环技术用于制冷空调领域是完全可行的，在每次循环过程中由外界热源输入一次高温解吸热可实现四次冷量输出；当采用NiCl2为高温盐吸附剂、MnCl2为中温盐吸附剂、BaCl2为低温盐吸附剂、NH3为制冷剂时，在加热温度为265℃、制冷温度为15℃、冷却温度为30℃的工况下，双效双重热化学吸附制冷循环的COP达到1.1。在此基础上分析了吸附制冷阶段和再吸附制冷阶段冷量输出过程的制冷功率变化特性，发现再吸附过程吸附反应强于吸附反应。

Abstract

A double-effect and double-way thermochemical sorption refrigeration system was set up. In the system

adsorption refrigeration

resorption refrigeration and internal heat recovery technologies were used to improve system performance. The feasibility and working performance of the proposed system was experimentally investigated. Experimental results showed that the present double-effect and double-way thermochemical sorption refrigeration cycle was feasible in the field of refrigeration and air conditioning. In one cycle

four cold productions were achieved at the expense of only one heat input. When NiCl2-MnCl2-BaCl2 -NH3 was employed as a group of sorption working pair

the obtained COP was as high as 1.1 at the desorption temperature of 265℃

the heat sink temperature of 30℃

and the refrigeration temperature of 15℃. Moreover

cooling power evolution of four cold output processes was analyzed and it was found that the resorption reaction is stronger than adsorption reaction.
