Economic Study Of Design Temperature Difference Of Secondary Heating Network

Central heating becomes popular in the world as a technique of improving our daily life, improving environment and saving energy. At present, many scholars are focusing on the design parameters. In China, the study of optimization on these design parameters has made a progress. But many research data on central heating in china has been taken from the relevant information abroad. There is no profound study on if these data is suitable for the present situation.Therefore, a method which is used in this paper is the economic analysis.The paper study design temperature difference of secondary heating network.At first, a survey focuses on secondary network analysis outdoor and indoor heating system. The survey getting some documents about secondary network system can supply material and basis.Secondly, the method about economic analysis is explained and determined in this paper. The mathematical model is constructed about particulars and expenditure of secondary network system. The method about specific frictional resistance is applied to the model.Thirdly, this paper analyzes the concrete network and definite the rudiment of heating network. The factor of material parameter is determined by the market price nowday.Lastly, the network is solved accord to the model of numerical analysis. The result is revealed in the paper by the chart. We can see intuitively the vary of economic difference in temperature. Some factors affecting the construction cost severely are analyzed and got the weighing.Throught the model, it was found that some disciplines which can improve the optimization of economic difference in temperature. The optimization can minimize initial cost of heating network and operation cost.
