| In recent years,with the improvement of the national economy and the continuous increase in investment in infrastructure construction along the line,the construction of facilities along the expressway in Hebei Province has made considerable progress.Energy saving and environmental protection are still the subject of today’s society.In order to actively respond to national policies,relevant departments have effectively fulfilled their social responsibilities and implemented a large number of cold and heat source system transformation projects.Due to the lack of scientific rationality in the selection of the plan,the initial investment,running costs and serious environmental pollution are frequently occurring.Therefore,how to choose a suitable local cold and heat source scheme that consume the least resources to achieve maximum economic benefits and make better use of renewable green energy sources are the issues that must be considered in the selection of cold and hot source facilities along the expressways,and it’s also the key of the study in this thesis.This thesis focuses on the status quo of cold and heat source facilities along the expressway in Hebei Province.Through the analysis of the cold and heat source methods,operation conditions and operational effects of the facilities along the highways in Hebei Province,the main deficiencies are pointed out,and it is necessary to reform the system of cold and heat sources.DeST software was used to carry out modeling and simulation calculations,on the basis of calculating the energy consumption of a typical building in a typical area of each climate zone obtained,the economic,technical conditions,environmental protection and social benefits of each program were compared and analyzed.Then Analytic Hierarchy Process was used to evaluate and optimize the scheme of cold and heat sources in the facilities along the expressway,and the best scheme of cold and heat source of typical buildings in typical climate zones in Hebei Province was obtained. |
