In a significant step towards sustainable building practices, the first solar-heating demonstration project was launched in Yongde County, jointly developed by the Gansu Provincial Research Institute of Building Materials Research and Design, the Institute of Electrical Engineering from the Chinese Academy of Sciences, and the Rural Energy Conservation and New Energy Laboratory at Tsinghua University. This initiative marked the establishment of a new pilot construction base for innovative building materials and energy-efficient technologies.
Originally, the demonstration building was a single-layer brick-concrete structure, which suffered from poor thermal insulation and high energy consumption. To address this, a series of energy-saving technologies were implemented, enabling the building to meet the national standard for energy efficiency at 65%. The heating system incorporated heat-pipe vacuum tubes, while a 22kW photovoltaic power generation system was installed on the roof to support production, lighting, and both heat storage and heating operations.
The heat storage system utilized 9 cubic meters of specially designed concrete as a thermal medium, paired with a 3-ton circulating water tank. Efficient radiators were used at the end-user level. After nearly four months of trial operation, the system successfully met the building's heating needs, providing up to 16 hours of continuous heating through the heat storage mechanism.
The successful operation of this demonstration system highlights the potential of solar heating technology as a viable solution for developing green, low-carbon buildings. It has the potential to significantly contribute to reducing air pollution and promoting the growth of energy-saving and environmental protection industries. Currently, engineers are working on optimizing the system to enable broader application in the future. Reporter: Zhang Xiaoyan
