摘要
蓄能空调系统涉及"源"侧电力供应和"荷"侧建筑冷热需求双重动态变化特性,系统的容量配置是一个技术经济寻优问题.受室内外多种因素共同影响,建筑冷热负荷每天的逐时分布规律差别较大,传统上仅基于设计日等典型周期逐时负荷分布规律的设计方法使得蓄能空调系统容量的配置不合理.突破传统设计方法的不足,提出以空调系统全年运行性能为导向的冷热双向全周期维度蓄能空调系统性能化设计方法,能够考虑到全供暖季、全制冷季每天的逐时动态负荷分布规律,耦合建筑冷热负荷双向需求,获得更加科学合理的蓄能空调系统容量配置方案.用具体案例进行了设计方法展示.
Abstract
The thermal storage air-conditioning system involves the dual dynamic characteristics of source-side power supply and load-side building cooling and heating load demand.Its system capacity configuration is a technical and economic optimization issue.Influenced by indoor and outdoor factors,the hourly distribution of building heating and cooling load varies greatly every day.The traditional design method only based on the typical cycle hourly load distribution such as the design day makes the capacity of the thermal storage air-conditioning system unreasonable.This article breaks through the shortcomings of traditional design methods.A performance-oriented design method of thermal storage air-conditioning system capacity is proposed,considering the hourly dynamic load distribution in the whole heating and cooling season,and coupling building cooling and heating load.Thus,a more scientific and reasonable capacity configuration scheme of thermal storage air-conditioning system is obtained.Taking an engineering project as an example,the design of thermal storage air-conditioning system capacity is proposed.
