由清华大学建筑节能研究中心、甘肃省建材科研设计院、中国科学院电工研究所联合研制设计的国内首座光热-光伏-储热联合运行的太阳能供暖示范建筑在甘肃永登省建材院中试基地建成。该太阳能供暖示范建筑主要由既有建筑节能改造系统、集热面积100平方米的热管式真空管集热系统、22千瓦屋顶光伏发电系统及9立方米的混凝土储热系统和3立方米的储热水箱组成。该建筑原为单层砖混结构,保温隔热性能差,建筑能
By the Building Energy Conservation Research Center of Tsinghua University, Gansu Province Building Materials Research Institute of Design, Institute of Electrical Engineering, Chinese Academy of Sciences jointly developed the first domestic solar thermal - photovoltaic - thermal storage solar heating demonstration building in Gansu Yongding Provincial Building Materials Institute pilot base Built. The solar heating demonstration building mainly consists of the existing building energy-saving renovation system, a heat-collecting vacuum tube heat collecting system with a heat collecting area of 100 square meters, a 22 kilowatts rooftop photovoltaic generating system and a 9 cubic meter concrete heat storage system and 3 cubic meters of heat storage Water tank composition. The building was originally a single brick structure, thermal insulation performance is poor, the building can
