大型室内水上乐园冬季热湿环境CFD分析

摘要

结合某大型室内水上乐园项目,通过CFD模拟预测冬季空调工况室内热湿环境.结果表明:人员停留区温度分布均匀,高度方向温度梯度小于3℃；人员停留区相对湿度满足设计要求,水面附近湿度较高,其影响随高度增加而减小；人员停留区风速小于0.2 m/s,舞台表演区风速小于0.15 m/s,但近送风口局部区域风速较高.风机盘管直吹围护结构防结露效果明显,侧墙部分区域可能结露.%Abstract With the air-conditioning system design of a large indoor water paradise,simulates the thermal and humidity environment by CFD.The results show that the air temperature is well distributed in the occupied zone,with its gradient less than 3 ℃ in the height direction.The relative humidity can meet the design requirement in the occupied zone,and is close to 100％ in the region above several pools and drifting river,and its influences weaken with the augment of height.The air velocity is less than 0.2m/s in the occupied zone and 0.15m/s in the stage area,and higher in value in local region near air inlets.The anti-condensation effect is evident by fan coil units blowing directly to the building envelop,but condensation may occur in some region of wall.
