两段式溴化锂吸收式热泵的性能分析

Performance Analysis of Dual Group Lithium Bromide Absorption Heatpump

介绍了一种在传统单效溴化锂吸收式热泵的基础上发展而来但COP值更高的两段式热泵,首先对两段式热泵的热力循环进行了理论分析,得出了其COP值高于传统单效热泵的原因。然后利用自编的热泵热力计算程序,通过实例计算对理论分析结果进行了佐证,并对两段式热泵的COP值优化进行了分析。结论表明两段式热泵确实比单效热泵具有更高的COP值。

In this paper, a dual group lithium bromide absorption heatpump which is based on single effect lithium bromide absorption heatpump is analyzed to figure out the reason why its COP is higher than that of the single effect heatpump. The theoretical result is verified by the calculation of real ease using the self-compiled program. In addition, the optimization of COP is studied.
