摘要
Abstract
The solar heating system coupled with seasonal thermal storage is a promising solution to solve the seasonal mismatch between the solar energy supply and heating demand.The thermal performance of the system in the heat storage season has a significant impact on the system's annual operation performance,and has a direct impact on the discharging process of the seasonal storage in the heating season.Therefore,based on the solar heating system coupled with seasonal thermal storage in Fanshan Town,Zhangjiakou,a dynamic simulation platform is built.The influence of different operation strategies on the performance of the system is analyzed by experiment and simulation methods.Results showed that the control strategies were significant for improving the heat collection performance of solar receiver and the exergy efficiency of the UWPS.The stratification of the seasonal storage has an impact on the collection efficiency of the receiver,especially at the end of the non-heating season.In addition,at the end of the non-heating season in typical year,the monthly solar collection efficiency could be increased by 4.8％in variable flow control compared to the temperature difference control.关键词
