近零能耗建筑中相变建筑材料的研究进展

Review on phase change building materials in nearly zero energy buildings

近零能耗建筑是采用被动式建筑设计和主动式节能技术、以最低的能源设备功耗获得舒适室内环境的建筑。相变建筑材料的使用可以提高建筑围护结构的热惰性,减少室内温度的波动,降低供暖、空调设备的容量,同时能与太阳能、空气能等可再生能源相结合,降低建筑设备能耗。从不同围护结构的角度介绍了相变建筑材料的分类与特点,综述了国内外相变围护结构的研究进展,列举了相变建筑材料在近零能耗建筑中的被动式设计案例。分析了相变建筑材料的研究方向,以及相变建筑材料在被动式设计和主动式节能技术上的发展趋势,为近零能耗建筑的研究和设计提供参考和依据。

Nearly zero energy buildings adopt passive architectural design and active energy saving technology to achieve a comfortable indoor environment with the lowest power consumption of energy equipment. The use of phase change building materials can improve the thermal inertia of building envelopes, reduce indoor temperature fluctuations, reduce the capacity of heating and air conditioning equipment, and reduce energy consumption of building equipment by combining with solar energy, air energy and other renewable energy. Presents the classification and characteristics of phase change building materials from the perspective of different building envelopes, summarizes the research progress of phase change envelopes at home and abroad, and lists the applications of phase change materials in passive design of nearly zero energy buildings. Puts forward the research trend of novel phase change materials and the development direction of phase change building materials in passive design and active energy saving technology, providing a reference and basis for the research and design of nearly zero energy buildings.
