| 摘 要： | １前言近年来，为了节约能源，保护环境，直燃型溴化锂吸收式制冷机在空调工程中得到了广泛的应用。目前制造的直燃机组其高压发生器的传热管大多水平布置。换热方式属于管外溶液池沸腾，传热效率不高、文献［１］提出传热管垂直布置，高温烟气在管外横向冲刷传热管，管外易于焊制环形肋及其他强化措施，气流掠过竖管时扰动大，对流边界层较薄；溴化锂溶液在管内换热属于垂直管内两相流动沸腾，其流动的动力来自气泡上升引射，这样。对流换热和沸腾换热都得到强化，整体传热性能增强。但目前国内对溴化锂溶液流动沸腾换热的研究报道还很少。…

| Abstract: | The tube conialmng three-dimensional ribs has great influence on LrBr--H2O's upwardflow boiling. Heat transfer coefficient AF is about 1.5~2.6, it is mainly edicted by specificrate of heat flow, pressure and east quality. In the range of experimental parameter, theauthor regresses the heat transfer equation of LiBr--H2O. |
