通风方式对辐射空调房间人体热感觉及皮肤温度的影响
摘要：采用主观问卷与实验测试相结合的方法，探讨了辐射顶板+混合通风与辐射顶板+地板送风2种通风方式下房间内人体热舒适性的差异，分析了通风方式对人体热感觉及皮肤温度的影响。结果显示：不同通风方式下各部位皮肤温度的差异与相应部位热感觉的差异存在不一致情况；通风方式对受试者整体热感觉的影响较小，而对局部皮肤温度及局部热感觉的影响较大。

Influence of ventilation mode on human thermal sensation and skin temperature in rooms with radiation air conditioning
Abstract: The difference of human thermal comfort in the room under the two ventilation modes of radiation ceiling plus mixing ventilation and radiation ceiling plus underfloor air distribution is investigated by using the method of subjective questionnaire and experiment, and the effects of ventilation mode on human thermal sensation and skin temperature are analysed. The results show that the differences in local skin temperature under different ventilation modes are inconsistent with those in thermal sensation of corresponding parts. The ventilation mode has a little influence on the overall thermal sensation of the subjects, but has a great influence on the local skin temperature and local thermal sensation.
Keywords: ventilation mode; radiation air conditioning; radiation ceiling; overall thermal sensation; local thermal sensation; skin temperature; mixing ventilation; underfloor air distribution;
