CFD analysis on thermal and humid environment of a large indoor water paradise in winter

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.
