从集热系统选择、集热器与建筑的结合、蓄热系统、运行策略等多个方面介绍了世博中心太阳能光热系统设计。该系统通过采用真空直流热管集热器,以车棚遮阳板的形式实现集热器与建筑的完美结合;采用高低温分级储热模式以及合理的运行策略,实现经济高效利用太阳能的目的。最后介绍了该系统的节能情况,及其在绿色建筑三星设计标识评价与LEED认证中的得分情况。
From the selection of collector system, the combination of collector and building, thermal storage system, operation strategy and other aspects of the Expo Center solar thermal system design. The system uses a vacuum DC heat pipe collector to achieve the perfect combination of collector and building in the form of a canopy sun visor. The high and low temperature staged thermal storage mode and reasonable operation strategy are adopted to realize the economical and efficient use of solar energy. Finally, the energy saving situation of this system is introduced, and its score in the evaluation and LEED certification of green building Samsung design logo is introduced.
