汽车余热溴化锂吸收式制冷研究

A Study on LiBr Absorption Refrigeration with Automotive Exhaust Heat

根据现有汽车空调的制冷系统和发动机循环冷却水系统结构特点,并结合单效溴化锂吸收式制冷机的性能,提出溴化锂吸收式制冷系统中的发生器由改造后的汽车发动机缸盖部分和冷却水系统部分共同组成,将溴化锂溶液充注在汽车发动机的冷却空腔内,代替原来的冷却液,进而实现制冷效果。本文实现了用一个单效溴化锂吸收式制冷机系统代替现有汽车空调的制冷系统和发动机冷却水系统,并进行了理论分析和设计计算。

Based on the structure and characteristic of automotive ref system, combing the performance of single-effect lithium bromide absorption tot of absorption refrigeration system is composed by the reconstructing a tern. The LiBr solution is filled into the engine cooling cavity to take the p tion effect. This paper realizes a single-effect lithium bromide absorption r conditioning refrigeration system and engine cooling system, We make a l rigeration system and engine circulation cooling water on refrigeration machines, we propose that the generautomotive engine cylinder head and cooling water syslace of original refrigerant, It carries out the refrigera efrigeration system replace the existing automotive airot of theoretical analysis and design and calculation.
