溴化锂硝酸锂混合溶液吸收式热泵性能研究
Performance of absorption-type heat pump with mixture solution of lithium bromide and lithium nitrate
摘要：
以水-溴化锂-硝酸锂作为新工质对（溴化锂和硝酸锂的摩尔比为4∶1），计算并比较了其与水-溴化锂工质对在单效吸收式热泵中的循环参数。结果表明，采用新工质机组的性能系数提高5%左右，防结晶性能也明显改善。

Abstract：
With the water-lithium bromide-lithium nitrate of mole ratio 4∶1 of lithium bromide to lithium nitrate as working pair, calculates and compares the performance with that of water-lithium bromide in single effect absorption-type heat pump. As a result, the coefficient of performance can be increased by 5% and anti-crystallization properties can be improved markedly by using the new solution.
