摘　　要：游泳馆湿负荷计算是游泳馆空调系统方案确定的基础。游泳馆内泳池散湿量大小与泳池水温、泳池水表面特性、室内温湿度、水表面空气流速、人员活动情况等多种因素相关。目前采用的游泳馆泳池湿负荷计算方法都是依据传质理论并结合实验数据提出来的,具有一定的适用条件,尚未形成一种统一的计算方法。文章通过对目前游泳馆泳池湿负荷计算方法进行定量计算分析,对比分析了其影响因素及差异性,研究发现:各关系式计算结果差异较大,但变化趋势总体一致,与池面气流速度、水温变化成正比,与室内空气温度及相对湿度变化成反比。同时,验证了湿负荷测试结果与关系式计算结果,得出结论:游泳馆湿负荷大小受室内空气相对湿度变化影响较小,受人员活动影响大,经过验证,推荐现阶段游泳馆空调工程设计采用ASHRAE手册关系式计算湿负荷。The calculation of humidity load is the basis of the air-conditioning system design in swimming pools.The wet load of the swimming pools is related to many factors,such as the water temperature,the water surface characteristics,the indoor temperature and humidity,the air velocity of the water surface,and personnel activities.At present,the wet load calculation methods of swimming pools are all based on mass transfer theory and combined with experimental data,which has applicable conditions and has not formed a unified calculation method.This paper compares and analyzes the differences and various influencing factors of these methods through calculation and analysis of several commonly used methods of wet load calculation in swimming pools.The research finds that:the calculation results of each relation differ greatly,but the change trend is generally consistent,which is proportional to the changes of the air velocity and water temperature,and inversely proportional to the changes of air temperature and relative humidity.At the same time,the humidity load test results and the relational results are verified,and the conclusion is drawn that the wet load of natatorium is less affected by indoor air relative humidity and more affected by personnel activities.After verification,it is recommended to use the ASHRAE method to calculate the wet load in the current design of natatorium air conditioning engineering.
