偏热环境下空调非等温可感送风对人体热舒适影响的实验研究
Climate chamber study on impacts of non-isothermal and sensible air supply on human thermal comfort in warm environments
摘要：
通过实验研究在2个工况下，低温稳态气流、低温仿自然风动态气流以及等温仿自然风动态气流方式下，受试者热感觉、热舒适和热环境满意度投票情况。实验结果表明，在室温为28~30 ℃、相对湿度为40%~45%的热环境下，平均送风速度为0.5~0.7 m/s、送风温度为28 ℃的气流能够使受试者达到舒适水平。建议当室温为28 ℃时，使用风扇提供平均风速为0.5 m/s的仿自然风动态气流进行人体降温；当室温为30 ℃时，使用空调提供平均风速为0.5 m/s、送风温度为28 ℃的仿自然风动态气流进行人体降温。
Abstract：
Performs the voting experiments of thermal sensation, thermal comfort and thermal environment satisfaction of the subjects in climate chamber on conditions of two combination of temperature and relative humidity and of three air supply modes of low temperature steady air movement, low temperature simulated natural wind air movement and isothermal simulated natural wind air movement. The results show that the thermal comfort of the subjects can be satisfied on conditions of indoor temperature from 28 to 30 ℃, relative humidity from 40% to 45%, mean air supply speed 0.5 to 0.7 m/s and air supply temperature of 28 ℃. Suggests that the human body should be cooled by simulated natural wind air movement with air speed of 0.5 m/s by ceiling fan when the indoor temperature is 28 ℃, while it should be cooled by simulated natural wind air movement with air speed of 0.5 m/s and air temperature of 28 ℃ by air conditioning devices when the indoor temperature is 30 ℃.
