摘　　要：结合青海西宁地区的气象资料及当地的气候变化特征,分析民用建筑采暖需求与供热量的关系,提出民用建筑主动式太阳能采暖技术的设计方案。分别从室内空气热平衡和热量传递两个方面,构建民用热过程数学模型。根据该模型下,安装集热器和蓄热器等太阳能采暖所需的设备,确定累计太阳辐照量和建筑供热负荷,计算建筑主动式太阳能的热量。最终通过强制循环控制,在设定的采暖时间内实现民用建筑的主动式太阳能采暖。通过采暖工况实验分析得出结论:与其他采暖技术相比,主动式采暖技术有效缩小了室内温度的波动量,并节省了约34.3%的能源消耗。Combining with the meteorological data in Xining area of Qinghai and the characteristics of local climate change,the relationship between heating capacity and heating demand of civil buildings is analyzed,and active solar heating technology for civil buildings is proposed. From the two aspects of indoor air heat balance and heat transfer,a mathematical model of the thermal process of civil buildings is constructed. Under this model,install the equipment required for solar heating such as collectors and heat accumulators. By determining the cumulative solar radiation and building heating load,calculate the building’s active solar heat gain. Finally,through forced circulation control,active solar heating of civil buildings is realized within the defined heating time. Through the experimental analysis of heating conditions,it is concluded that compared with other heating methods,active heating technology effectively reduces the fluctuation of indoor temperature and saves about 34. 3% of energy consumption.
