水幕空调的应用分析
Application of water curtain air conditioning
摘要：
某五星级酒店利用人造瀑布形成的水池来改善室内热环境，分析比较了在热压通风、夜间风机运行、空调运行三种工况下水池中采用10～16 ℃不同温度的冷水改善室内热环境的效果。结果显示，利用风机和水池的低温冷水可以使酒店部分区域在不开启空调的情况下满足人体热舒适要求。建议设置水池温度为10 ℃，白天运行空调，夜间部分区域运行风机，部分区域运行空调，可以达到一定的节能效果。
Abstract：
A five-star hotel adopts the pool with an artificial waterfall to improve the indoor thermal environment. Analyses and compares the improving effect of different temperature chilled water from 10 ℃ to 16 ℃ in the pool on the indoor thermal environment in the three conditions of natural ventilation under thermal pressure, fan and air conditioning running at night, and air conditioning. The results show that using fan and low temperature chilled water in the pool can meet occupants’ thermal comfort requirement in part of the hotel without running air conditioning units. Suggests that the temperature of chilled water in the pool is set at 10 ℃, the air conditioning units run in the day, and that the fans run in some areas and air conditioning units run in the rest at night to realize energy saving.
