摘　　要：本文通过在人工环境室中设置电热膜模拟外墙,研究辐射顶板+地板送风空调房间室内热舒适性.结果表明:室内设定温度为26℃时,较低和较高外墙负荷工况条件下辐射顶板表面温度分别为20℃及15~17℃时,靠外墙受试者的热舒适感受明显优于靠内墙受试者.此外,靠内墙受试者的局部热感觉稍高于靠外墙受试者,而靠内墙受试者的局部皮肤温度却略低于靠外墙受试者.因此,外墙负荷及人员位置对辐射空调房间人员热舒适性具有显著的影响,在进行辐射空调系统气流组织设计时应该考虑外墙负荷及人员位置的影响.The electric heat film was put on the external wall in the artificial environment room to simulate the heat transfer of external wall.In this paper,the indoor thermal comfort in a chilled ceiling room with underfloor air distribution was studied.The results show that when the indoor temperature was set at 26℃,the subjects near the external wall significantly felt more comfortable than those near the inner wall under the condition of chilled ceiling surface temperature 20℃.with low cooling load and 15℃ to 17℃ with high cooling load.In addition,the local thermal sensations of the subjects near the external wall were slightly higher than those near the inner wall,whereas the local skin temperature of the subjects near the inner wall was slightly lower than those near the external wall.Therefore,the cooling load of the external wall and location of the occupant had a significant impact on the indoor thermal comfort in a chilled ceiling room with underfloor air distribution,and it is important to consider the effect on them during the design stage.
