摘要
本文提出一种以吸附式制冷单元为高温级、以双效溴化锂吸收式制冷单元为低温级的复叠式多效制冷循环．通过热能在系统中的分级与多效利用，可提高制冷系统ＣＯＰ．在该循环中，吸附式单元工质对的温度高于２００℃时，也不会产生腐蚀作用，因而是一种工艺上易于实现的新型制冷循环．
This paper presents an adsorption-absorption cascading multi-effect refrigeration cycle, which consists of a high-temperature stage of solid adsorption unit working with zeolite-water and a low-temperature stage of double-effect absorption unit working with LiBr-water. The COP of Cycle can be greatly Anproved by the efficient utilization and recovery of energy within the system. There is no corrosive problem though the temperature of working pair is higher than 200℃ in the adsorption unit. This new cascading refrigeration cycle is more feasible to be realized in engineering.
