Research On Optimal Design Of Centralized Heating System Networks

First of all, this paper introduces the principles and methods which should be followed of the actual network model when it is processed. And then hydraulic calculation of the model is established on central heating pipe network. The classical method of basic circuit analysis is used to solve the hydraulic model. And the preparation central heating pipe network of south downtown in Cheng De city is on hydraulic calculation which is used Matlab language. Then we obtain the flow and pressure drop of each pipe which laid the foundation for optimal design of the pipe network later introduced in this article. The optimized model of the heating pipe network is improved in the latter part the final objective function of the model is based on the annual conversion cost of heating network The overall pipeline network construction costs, annual running costs of the network and the network cost of the annual heat loss is specifically included. Diameter of the pipe discrete is objective function in which the decision variables And the hydraulic constraints is considered and corresponded the actual of the actual project. Then the simulated annealing is successfully invoked The solution of the optimal design of heat pipe the model is achieved Also specific Matlab Program which is prepared solved optimization calculation of the example The diameter of each group is obtained The optimized pipe network is hydraulic calculated the results with optimize and the results without optimization are compared the overall cost of the network is reduced on the basis A variety of pipe network optimization results have also been improved.
