摘　　要：为明确寒冷气候区办公建筑辐射供暖和对流供暖模式下的室内热环境参数是否能满足人体热舒适需求,本研究选取西安市不同供暖模式的办公建筑为调研对象,同时进行了室内物理环境测试和人体热舒适主观问卷调查,调研期间共获得1 120份有效问卷。结果显示:对流供暖模式下室内空气温度和竖直温差显著高于辐射供暖,且室内存在过热现象;辐射和对流供暖的中性温度分别为17.4℃和20.4℃,较高的室内空气温度形成了较高的中性温度和可接受温度上限。To determine whether the indoor thermal environment parameters in office buildings under radiant and convection heating modes in the cold climate zone can meet the requirements of human thermal comfort,this study selects the office buildings with different heating modes in Xi’an as the research object,and carries out indoor physical environment tests and human thermal comfort subjective questionnaires,and 1120 valid survey questionnaires are collected during the investigation.The results show that the indoor air temperature and vertical temperature difference under the convection heating mode are significantly higher than those under the radiant heating mode,and there is overheating in the room.The neutral temperatures of radiant and convection heating are 17.4℃and 20.4℃,respectively.The higher indoor air temperature forms a higher neutral temperature and an upper limit of acceptable temperature.

关 键 词：辐射供暖 对流供暖 办公建筑 室内热环境 热舒适 中性温度 可接受温度 现场调研
