Design Calculation and Numerical Analysis of Lithium Bromide Absorption Heat Pump with Large Temperature Difference

论文系统地整理了溴化锂吸收式热泵机组内部工质参数计算方法,指导并应用于国内某长距离、大温差供热工程中,达到了预期效果,可为类似城市集中供热改扩建热力站工程采用以溴化锂为工质的吸收式热泵机组实现大温差供热提供参考。论文围绕大温差换热机组设计计算展开探讨。

This paper systematically sorts out the calculation methods of the internal working fluid parameters of lithium bromide absorption heat pump units,guides and applies them to a domestic long-distance,large temperature difference heating project,and achieves the expected results.It can be a reference for the reconstruction and expansion of similar urban central heating station projects using lithium bromide as the working medium of the absorption type heat pump unit to achieve large temperature difference heating.This paper discusses the design and calculation of large temperature difference heat exchange unit.
