摘要(Abstract)：

针对厂房内高温热源散发的热量向工作区域扩散的问题,设计出一种基于厂房高温热源的隔热降温墙体。研究了管路中心距、空腔厚度、保温层厚度对该墙体隔热降温性能的影响,采用正交试验设计的方法设计了上述结构参数的9个组合方案,利用CFD数值模拟的方法对每个组合方案下墙体的隔热降温性能进行了模拟。研究结果表明:以墙外侧壁面温度和墙体供冷量作为评价指标,分别对模拟结果进行极差分析和方差分析,得到两种分析方法结果具有一致性,并在分析中可知各因素对墙体性能影响的显著程度,最终得到最优结构方案:管路中心距100 mm,空腔厚度60 mm,保温层厚度30 mm,该研究大大减少了试验或模拟工作量,提高了模型结构优化效率和性能分析速度,为外围护结构的节能设计提供了新的思路和方法。
For the problem of spreading of the heat dissipated by the high-temperature heat source in the workshop to the working area,a heat-insulating and cooling wall based on the high-temperature heat source of the workshop was designed. The influences of pipeline center distance,cavity thickness,and insulation layer thickness on the thermal insulation and cooling performance of the wall were studied.The orthogonal experimental design method was used to design 9 combination schemes of the above structural parameters,and the CFD numerical simulation method was used to simulate the thermal insulation and cooling performance of the wall under each combination scheme.The results of the study show that when the temperature of the outer wall surface and the cooling capacity of the wall are used as the evaluation indicators to carry out range analysis and variance analysis of the simulation results,the results of the two analysis methods are consistent,and in the analysis,the significant degree of influence of each factor on the wall performance.Finally the optimal structural scheme was obtained: the pipeline center distance is 100 mm,the cavity thickness is 60 mm,and the insulation layer thickness is 30 mm.The present research greatly reduces the workload of experiments or simulations,and improves the efficiency of model structure optimization and speed of performance analysis.It provides new ideas and methods for the energy-saving design of the envelope structure.
