商场用热虹吸管热回收机组适宜工作模式的研究
Optimal operation mode of thermosyphon heat recovery units for shopping centers
摘要：
在分析热虹吸管换热器换热效果影响因素的基础上，通过分析试验机组在商场空调系统实际应用环境中的运行数据，综合考虑室外新风温度大范围变化、不同倾斜角度对换热器温度效率的影响，得到了实际运行环境下机组的适宜工作模式。进一步利用PLC对机组倾斜调节机构进行控制设计，实现了样机在目标工作模式下的高效运行，运行效果良好。

Abstract：
By analysing the influencing factors of heat transfer efficiency of thermosyphon heat exchangers and the practical operating data of an experimental heat recovery unit used in a shopping center, and concerning about the influence of unit incline angle on the temperature efficiency of heat exchangers under a wide variable scope of outdoor air temperature, obtains an optimal operating mode of the unit. Further designs an incline angle regulation mechanism using a programmable logic controller (PLC) making the unit working at the optimal mode with a high efficiency.
