摘要
根据现有汽车空调的制冷系统和发动机冷却水及排气系统的结构特点,结合溴化锂吸收式制冷系统的工作原理,提出将汽车排气管和发动机冷却水箱进行结构改造作为溴化锂吸收式制冷系统的发生器,代替传统的汽车空调的制冷和采暖系统及发动机冷却系统。并对该溴化锂制冷系统进行了热力计算和传热面积的计算,计算结果表明,溴化锂制冷系统充分利用了废气余热和冷却水余热,减少了汽车油耗,并且改造后的排气热交换器和冷却水箱传热面积小,结构简单紧凑。
Based on the structure and characteristic of automotive refrigeration system and engine circulation cooling water system and exhausted waste heat system,combing the working principle of lithium bromide absorption refrigeration system,the authors used the automotive exhaust pipe and cooling water tank improved as the generator of the lithium bromide absorption refrigeration system,which might realize the objective using the lithium bromide absorption hot-cold water unit to replace the automobile air conditioning refrigeration and heating system and the automobile engine cooling system.The methods of the thermodynamics,the heat transfer,the hydrodynamics are used to do the computation of the thermodynamic and the heat transfer area of the lithium bromide absorption refrigeration system.The result shows that it makes good use of exhausted heat of engine circulation cooling water and exhausted waste and reduces the consumption of oil.And it'structure is simple and compact for small heat transfer area of the automotive exhaust pipe and cooling water tank improved.
