摘　　要：碳达峰碳中和背景下,可再生能源利用技术备受关注。建筑领域,清洁无污染的太阳能已被广泛应用于冬季供暖和夏季制冷。然而,太阳能的时效性和地域性一定程度上限制了太阳能利用的推广。因此,TES(储能技术)的发展对于最大程度地弥补太阳能利用的不足至关重要。分别介绍了SHS(显热储热)、LHS(潜热储热)和TCES(热化学储热)3种储热类型的原理及技术关键,重点对太阳能热水系统中级联储热技术、纳米增强相变材料储热技术和高导热复合相变储热技术进行深入的阐述。通过储热材料的选取和储热关键技术的研究,旨在提高太阳能供暖效率,同时也为其他可再生能源的利用提供参考。Renewable energy utilization technologies receive much attention in the context of carbon neutrality.In the construction field,clean and non-polluting solar energy was widely used for winter heating and summer cooling.However,the intermittency and localization of solar energy somewhat limite its widespread adoption.Therefore,the development of TES(thermal energy storage)technology is crucial to address these deficiencies in solar energy utilization.The principles and technical aspects of SHS(sensible heat storage),LHS(latent heat storage)and TCES(thermochemical thermal storage)were introduced,respectively.It focused on advances in cascade thermal storage technology,nano-enhanced phase change material thermal storage technology and high thermal conductivity composite phase change thermal storage technology in solar water heating systems.By selecting advanced thermal storage materials and studying key thermal storage technologies,this paper aims to improve the efficiency of solar heating and cooling,and also provides a reference for the utilization of other renewable energy sources.
