娱乐性室内游泳馆湿负荷计算方法的研究与分析

摘要

The main factor of indoor natatorium air environment effective control depends on the accurate prediction and calculation of moisture load.At present there are various calculation methods about indoor natatorium moisture load at home and abroad,and the calculation results vary widely.Through comparing the calculation method,calculation formula and parameter selection,analyses the advantages and disadvantages of different calculation methods and the existing problems.Divides the indoor moisture sources into the pool,pool wetland and person,three main moisture sources.Applies the heat exchange and mass transfer analogy principle,establishes the corresponding physical models to the moisture sources, puts forward the moisture load calculation formula based on recreational indoor natatoriums,and verifies the accuracy of the model calculation.%游泳馆室内空气环境有效控制的主要因素取决于对湿负荷的准确预测与计算。目前国内外关于室内游泳馆湿负荷的计算方法不一，计算结果相差很大。通过对国内外游泳馆散湿量的计算方法、计算公式及参数的选择进行对比，分析了各种计算方法的优缺点以及存在的问题。将室内散湿源分为池水、池边湿地和人员3种。运用热交换和质交换类比原理，建立了与各散湿源相对应的物理模型，提出了基于娱乐性室内游泳馆散湿量的计算公式，并验证了模型计算的准确性。
