本文在建立室内冰场稳定温度场数学模型的基础上,通过电子计算机模拟,在给定场地构造和材料热物性参数的条件下,分析计算了场地排管管径、排管间距和室内气象参数等对排管表面温度和冰面温度不均匀度的影响。继而通过技术经济比较,给出了室内冰场的最佳排管间距,(即在保证冰质要求的前提下,使冰场及制冷系统的总费用达到最小)。文章给出的几种典型条件下最佳排管间距的取值范围,可供设计人员参考。
In this paper, based on the establishment of the mathematical model of the stable temperature field of the indoor ice rink, through the computer simulation, under the conditions of the given site structure and the thermal physical properties of the material, the pipe diameter, the spacing of the pipe and the indoor meteorological parameters are calculated and calculated. The effect on the surface temperature of the row tube and the unevenness of the ice surface temperature. Then, through technical and economic comparisons, the optimal spacing between indoor rinks is given (ie, the total cost of ice rink and refrigeration system is minimized under the premise of ensuring the ice quality requirements). The range of values for the best row spacing for typical conditions is given for designers’ reference.
