As the world’s energy crisis aggravates and the environment worsens,energy conservation and emission reduction must be a general trend and will become more and more important.At this stage,the planning and design of energy is still mainly based on infrastructure construction.The application of the idea of "adjusting measures to local conditions" is not high,and the use of renewable energy and low-grade energy is neglected.Therefore,the cleanliness and economy of energy use should be even greater Much attention should be drawn from the assessment of the amount of energy resources,the production process and the energy consumption process,based on the principle of local conditions,the current national economy,future economic development trends and social development,based on the investigation and analysis of the energy consumption process Low-carbon energy consumption system.Based on the summarization and analysis of the architectural features of the existing energy and industrial parks in Shenyang,this paper makes use of the available energy to realize the efficient and energy-saving utilization of energy.Based on the theory of regional energy planning and comprehensive resource planning,the author studied the theory of energy bus,proposed the design method and technical route of energy bus system,and made theoretical analysis of the energy transfer process in energy bus heating system The relational expression of the influence of power changes before and after the heat source mixed water of energy bus heating system is obtained:△W%=f(Thi1,Thi2,Tli1,φi,ωi).In this paper,the research and calculation of demand-side energy sources in Shenyang are as follows:Shenyang’s electricity development is rapid and sustainable,power supply is stable;natural gas sources are diverse,technology is mature,the number of users is rapidly increasing;Shenyang City,the annual total solar radiation is about 5500MJ/(m2a),the daily emission of about 3.9KWh/m2,and solar energy resources can be used;The development of wind power in Faku County,Kangping County and other rich wind resources to establish power plants,and the annual average wind speed in Shenbei New Area is only 3m/s,lack of wind resources,not suitable for the establishment of wind power plants;in Shenyang,due to a Some factors,it is not recommended to use water source heat pump,the proposed use of ground-source heat pump,and simulated ground-source heat pump system simulation,the results show that the operation is stable;Shenyang sewage treatment on a large,is available resources.On the basis of the existing heating system,the author proposes five kinds of energy bus systems and four kinds of pipe networks,analyzes the transmission radius of the energy bus system,and obtains the relationship between the radius and the pipeline average specific friction and the heating efficiency at the customer side,The relationship is:εexEBS=50 5cop/323 5+1.83*10-3(2.6*Rmx10-4+11)cop.Finally,Finally,based on the design method of the proposed energy bus system,the author analyzes a case of an industrial park in Shenyang.When author simulated the construction load of an industrial park in Shenyang City,author put forward the simplification method of building structure classification in the industrial park.Using this method will greatly improve work efficiency and help to complete the subject accurately.Meanwhile,during the heating season,The indoor and outdoor temperature in the park is calculated and the heating load is calculated on an hourly basis.Compared with the simulated value,the simulation results show that the error between the simulated value and the calculated value does not exceed 10%,and the simulation of the former by the software simulation more precise.The energy bus system of this industrial park is designed and simulated by TRNSYS software.The simulation results show that the design scheme is reasonable and the energy saved compared with traditional energy sources is 2.86 million tons of coal or 0.506 million cubic meters of natural gas.
