RESEARCH ON PASSIVE ADJUSTMENT OF BUILDING SPACE ENERGY CONSUMPTION BASED ON ENVIRONMENTAL MULTI-INDEX COUPLING TECHNOLOGY

摘要

In order to improve the problem that the index matching degree of energy consumption in building space after passive adjustment is not high,this paper studies a passive adjustment method of building space energy consumption based on environmental multi-index coupling technology.Firstly,the passive adjustment index of energy consumption is determined according to the comprehensive environmental multi-index,and the weight values of the environmental multi-index are obtained by using the fuzzy relationship.Then,the obtained weight values are used as the judgment basis and combined with the coupling technology to establish the building space energy consumption conversion model and dynamic thermal network model.After that,based on the quantitative relationship between the indicators obtained above,the end load change of the building space is simulated,a passive adjustment strategy is formulated,and the energy consumption adjustment of the building space is converted into the control of the energy-consuming pump,and the passive adjustment of the energy consumption of the building space is finally achieved.The results show that the passive adjustment method studied in this paper has an index matching degree of 0.822,which is the highest degree of matching among environmental multi-index.This method can prove the feasibility of improving the energy consumption in the building space after passively adjusting the low index matching degree.
