辐射空调系统的低设计方法研究

摘要

本文将建筑的能量供应链分为围护结构、室内空气、辐射末端、配水系统、蓄能系统、产能系统和空气处理系统等子系统,使用分析的热力学方法,根据各子系统自身的能量传输特性,分别进行了准稳态或动态的分析,推导得到各子系统的平衡方程式,并确定了输入、输出、消耗及储存的计算公式,建立起辐射空调系统的低设计方法。%The energy supply chain of buildings is divided into subsystems, including building envelope, room air, radiant system, distribution system, storage system, generation system and air handling system. Based on the exergy analysis method, the paper makes quasi-steady or dynamic analysis on energy transfer process of the subsystems. Exergy balance equations of each subsystem are derived, and the calculation formulas of exergy input, exergy output, exergy consumption and exergy storage are defined, then low exergy design method of radiant air conditioning system is gained.
