摘　　要：由于面积大、空调末端设备多、占用情况多样等原因,建筑内部大空间的热舒适调控难度较大,北方地区供暖期的调控难度更加明显,并常常伴随着舒适性问题。本文采用数据实测的方式,以北京某办公楼为例,对北方地区供暖期间典型大空间的温度分布情况进行了分析,并提出了提升热舒适性的末端设备智控方法。结果表明,大空间内存在明显的冷热不均现象:无太阳辐射的情况下,同一时间点、不同距窗距离的测点温差可达3℃;考虑太阳辐射时,同层温差可达9.5℃。基于精细化调控需求和物联网技术支撑,本文提出了综合考虑舒适与节能的末端智控探索方向,为进一步落实大空间热舒适调控方法的优化和应用提供数据与理论支持。Due to the large area,big number of air-conditioning terminal equipment and various occupancy conditions.it is difficult to control the thermal comfort of large spaces inside the building.especially in the heating period in northern areas,often accompanied by comfort problems.Taking an office building in Beijing as an example,this paper analyzes the temperature distribution of typical large spaces during heating in northern China by means of data measurement,and proposes the intelligent control method of terminal equipment to improve thermal comfort.The results show that there is an obvious unevenness of temperature in large spaces:In the absence of solar radiation,the temperature difference between measuring points at the same time point and different distances from the window reaches 3C;When solar radiation is considered,the temperature difference of the same floor reaches 9.5C.Based on the demand for refined regulation and the technical support of the Internet of Things,this paper puts forward the exploration of terminal intelligent control with comprehensive consideration of comfort and energy saving.providing data and theoretical support for further optimization and application of thermal comfort regulation methods in large spaces.
