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。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.
