Orthogonal Design for Thermosyphon Operated in Absorption Refrigeration Cycles

热虹吸泵是小型无泵溴化锂吸收式制冷机的核心部件,对制冷机的运行及工作性能起关键影响。本文根据溴化锂吸收式制冷循环的设计要求,以热虹吸泵理论模型和性能模拟结果为指导,进行了热虹吸泵沿程加热可视化试验装置的方案设计和部件设计,搭建并调试成功试验装置。采用正交试验法研究加热量、系统压力和沉浸比等因素对热虹吸泵提升性能的影响,分析得知,对于热虹吸泵提升性能影响最大的因素是加热量,次要影响因素是系统压力,沉浸比对其影响最小。

Thermosyphon was the core component of mini-type solar absorption refrigerator.Its efficiency decided the perform-ance of mini-type solar absorption refrigerator,and mostly depended on the capability of lift pipe.In this paper,according to the design requirements of lithium bromide absorption refrigeration cycle,thermosyphon theoretical model and performance simulation results,we has designed the experiment device and parts of thermosyphon visualization,successfully build and debug experiment device.Using orthogonal test method research factors such as heat,system pressure and immerson ratio influence on thermal si-phon pump performance,the analysis indicates that for the thermal siphon performance,the most important influencing factor is heat,the secondary factor is system pressure and the immerson ratio has minimal impat.
