大型室内水上乐园冬季热湿环境CFD分析
CFD analysis on thermal and humid environment of a large indoor water paradise in winter
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.
