摘　　要：随着人类社会的快速发展,人们对建筑环境的舒适度要求越来越高,但建筑能耗已逐渐成为绿色建造节能的突出性问题。相变储能技术是指通过相变材料的储热特性来储存或释放热量的热储能方式,最终实现调控温度的目标。近年来,相变材料凭借其储热密度高、等温相变等特性,常以潜热形式放出或吸收热量,从而在建筑领域中发挥不可替代的作用,使相变储能技术在建筑领域中具有良好的应用前景。随着相变材料的制备、复合、封装技术的不断发展,越来越多的相变材料与建筑材料、构件结合使用,为建筑领域的保温储能材料提供了新的发展模式。鉴于此,本文从建筑领域中常见的相变材料出发,以固液相变材料为例,对相变材料的传热理论、封装方法、传热储能、工程应用等几个方面的研究和应用情况进行了简要的介绍与综述,提出了相变材料未来在建筑领域的推广应用中可能存在的关键科学问题、面临的风险挑战,并展望了其未来的发展方向。With the rapid development of human society,people have increasingly higher demands of construction indoor thermal comfort,but the continuous increase of building energy consumption in the process of building development is a prominent issue of building energy conservation.Phase change energy storage technology refers to the storage or release the heat through the thermal storage characteristics of phase change materials,and ultimately achieve the goal of temperature regulation.In recent years,the high heat storage density,isothermal phase change process,releasing or absorbing heat by latent heat makes phase change materials a unique advantage in the energy storage technology which in turn enjoys bright prospects in their application in construction field.With the continuous development of phase change material preparation,composite and encapsulation technology,more and more phase change materials are incorporated in building materials and components,which provides a new development model for thermal insulation and energy storage materials in the construction field.This paper starts with ela-borating on the traditional phase change materials and further reviews the heat transfer theory,incorporation technique,heat transfer and energy storage,and engineering applications of phase change materials commonly used in construction field,and looks forward to the problems,challenges,and future development direction of phase change materials research and application in this field.
