阐述了基于TABS(Thermally Active Building Systems)的建筑围护结构蓄冷的工作原理,从蓄冷运行原理、冷源、控制策略以及实际工程应用等方面简述了该方式供冷的研究现状及应用情况.这类系统通过埋设于建筑围护结构中的辐射末端对空调房间进行冷却,对于间歇运行的建筑,可借助围护结构本身的热容实现蓄冷.主要介绍了该蓄冷模式下的末端结构、运行控制策略、天然冷源利用情况、设计要点、部分应用案例等.对采用嵌入式辐射末端供冷的空调系统,参照此模式运行,可实现一定的节能及运行费用的降低等,对工程应用具有良好的借鉴意义.
Study and Application of Building Envelope Cooling Storage Based on TABS
The working principle of building envelope cooling storage based on TABS(Thermally Active Building Systems)was introduced,and the current research and applications of this method were briefly described,including the system operation principle,cooling sources,control strategy,and practical engineering applications.In such systems,rooms are cooled through radiant units buried in the building envelope.For buildings operated intermittently,the heat capacity of the building envelope can be used to store cooling energy.The structure of applicable radiant units,operation control strategy,utilization of natural cooling sources,design concerns,and some application cases were mainly presented in this paper.Based on this operation method,energy saving and operation cost reduction can be realized for cooling systems with embedded radiant units,providing a good reference for engineering applications.
