健身房室内空气质量数值模拟分析

The Numerical Simulation Analysis of Indoor Air Quality in Gym

目的 研究健身房内的空气质量,分析健身房环境的影响因素,为打造健康锻炼环境提供设计参考。方法 实测健身房室内的温度、相对湿度、风速、污染物质量浓度,使用Fluent软件对夏季开馆初期以及人员高峰期时健身房室内的污染物质量浓度、温度、风速等分布进行模拟。结果 模拟得到开馆初期室内VOC存在明显的堆积,为0.68~0.94 mg/m^(3),与实测值相差0.002%~0.007%;人员高峰期时操厅及私教室区域CO_(2)堆积严重,CO_(2)体积分数平均体积分数约0.162%~0.170%;与实测值差0.001%~0.009%,同时室内温度明显升高。结论 健身房开馆初期空调系统难以在短时间内排出室内堆积的VOC;人员高峰期时通风系统难以将CO_(2)及时排出或稀释,同时人员的密集使得室内温度不断升高,室内气流存在死角。

In order to provide the design and use reference for a healthy exercise environment air quality in gyms was studied and the influencing factors of the gym environment was analyzed too.Based on the measured value of temperature,relative humidity,wind speed and pollutant quality concentration in the gym,the distribution of pollutant quality concentration,temperature and wind speed during the early opening of the museum in summer and the peak of personnel were simulated by Fluent software.The simulated results show that the obvious accumulation of VOC concentration in the early opening of the museum is found and the concentration of VOC is 0.68~0.94mg/m^(3),and the difference between the measured value and simulated value is between 0.002%and 0.007%.During the peak of personnel period,in the private classroom and the jump room the CO_(2) concentration accumulation is serious,and the average CO_(2) volume fraction is about 0.162%~0.170%;the difference from the measured value is 0.001%~0.009%.At the same time,the indoor temperature increased significantly.So in the early opening period of the gym,it is difficult to discharge indoor accumulation of VOC in a short time by Air conditioning system,and difficult to discharge or dilute CO_(2) concentration by the ventilation system during the peak period of personnel.The density of personnel is the reason of the indoor temperature increase,and there is a dead corner in the indoor airflow.
