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.
