塑料管单效溴化锂吸收式制冷机理论与实验研究

Theoretical and Experimental Research of Single-effect Lithium Bromide-water Absorption Chillers Using Plastic Pipes

溴化锂吸收式制冷机在工业中有着广泛的应用,但传热管腐蚀及其引起的冷量衰减一直以来是人们难以解决的问题。采用塑料传热管代替铜传热管有望解决这个难题。分析了单效溴化锂吸收式制冷机的理论循环,对塑料管单效溴化锂吸收式制冷机进行了热力计算和传热计算,设计了塑料管单效溴化锂吸收式制冷机的结构,为塑料管单效溴化锂吸收式制冷机的实验性能测试提供参考依据。

There are extensive applications of lithium bromide - water absorption chillers in industry, but the heat exchanger corrosion and refrigerating capacity loss are very dilticuh to be solved,In our research, the problem was solved by using plastic heat transfer pipes instead of copper pipes. Theoretical circulation of single - effect lithium bromide - water absorptian chillers asing plastic pipes was analyzed. Thermal calculation and beat transfer calculation were made for single - effect lithium bromide- water absorption chillers using plastic pipes.The experimental facility of lithium bromide - water absorption chillers using plastic pipes was designed.And these are reference for the performance testing of single - effect lithium bromide- water absorption chillers using plastic pipes.
