摘要
提出了一种新型的吸收式热泵循环,并对高温高浓度条件下溴化锂溶液的饱和蒸汽压及结晶温度进行了测试,在此基础上分析了中、低温余热温度对所产蒸汽压力的影响。结果表明:本文的吸收式热泵开路循环以中温余热为发生器热源而以低温余热为蒸发器热源,可产0.5MPa以上的蒸汽,其性能系数理论上可接近于1。
A new absorption heat pump cycle has been proposed and necessary data of the saturated vapor pressure and crystallization temperature for lithium bromide solution under conditions of high temperature and concentration have been measured. Upon these data, operation parameters for the cycle are determined, and effects of medium and low temperature waste heat＇s temperatures on the produced vapor＇s pressure are discussed. This study showed that by applying the new absorption heat pump cycle which utilizes the middle temperature waste heat as the heat source of generator and the low temperature waste heat as the heat source of evaporator, vapors of above 0. 5MPa can be produced with a COP theoretically approaching to 1.
