摘要

提出一种以沸石 -水为工质对的单效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吸附 -吸收复叠式三效制冷循环 .高温热源首先加热吸附式单元

通过能量在系统中的多效利用

从而提高系统性能系数 (COP) .相比于三效溴化锂吸收式制冷循环

复叠式循环中吸附式单元工质对温度高于 2 0 0℃时

也不会腐蚀材质

因而是一种工程上易于实现的新型制冷循环 .对该循环的热力性能进行了研究

Abstract

This paper presents a novel adsorption-absorption cascading triple-effect refrigeration cycle

which consists of a high-temperature stage of single-effect solid adsorption unit working with zeolite-water and a low-temperature stage of double-effect liquid absorption unit working with LiBr-water.High-temperature heat source is added into adsorption unit first

and its adsorption heat is then transferred to the high-pressure generator of absorption unit.The COP of the cycle can be greatly improved by the efficient utilization of energy in the system.Compared with the traditional LiBr/water triple-effect absorption system

there is no corrosive problem though the temperature of working pair could be higher than 200℃ in the adsorption unit.This new cascading refrigeration cycle is feasible in engineering.The thermodynamic characteristics of this cycle are discussed.Some simulation results are presented as well.
