强化室内空气流动以改善热舒适的节能研究
Energy saving research on strengthening indoor air movement to improve thermal comfort
摘要：
基于热舒适实验，研究了提高室内空气流速对人体热舒适的改善程度以及空气流速的合理取值。研究结果表明，可以通过提高空气流速保持室内标准有效温度SET*不变，从而可适当提高室内温度、相对湿度的设定值，达到节能的目的。以天津地区为例，分析结果表明，空调运行时间大大缩短，直接蒸发冷却方式的利用率得到提高。

Abstract：
Based on a thermal comfort experiment, studies the influence of increasing air velocity on human thermal comfort and the proper air velocity. The results show that SET*(standard effective temperature) could remain unchanged by increasing air velocity, thereby the design values of temperature and relative humidity could be properly increased to save energy. Taking Tianjin as an example, analyzing results show shorter operation period for air conditioning systems and higher utilization ratio for direct evaporative cooling mode.
