Technical Of Natural Gas Distributed Energy System Application In Tongzhou Hospital

Today,more and more institutions and individuals around the world pay more attention to energy.A large number of valuable research results of distributed energy resources with high energy efficiency have been transformed into advanced technology and the world-leading equipment.The colleges and the equipment manufacturers of our country are also following the international trend and investing a lot to develop distributed energy.However,it is still undeniable that China is a novice in the field of distributed energy technology research and does not have the ability to produce first-class products.To develop this technology,there is still a long way to go.In this study,a hospital project in Tongzhou was cited as an example to analyze the operation characteristics of distributed energy combined cooling,heating and power system(CCHP).Make a technical and economic comparison with the regular design under the same operation effect,and find the advantages of gas CCHP in hospital projects.First of all,after analyzing the characteristics of Tongzhou hospital project,the De ST energy consumption analysis software was used to simulate the building energy consumption,and the load structure of the hospital project in the aspect of cold,hot and electricity was summarized.The analysis software used the outdoor hourly temperature in Beijing as meteorological conditions,and the annual total energy supply was obtained.Second,according to the analysis results of De ST,a set of natural gas distributed energy application scheme suitable for Tongzhou hospital project is designed based on the service conditions and characteristics of each major equipment.Third,a regular plan is designed and selected for the project,and the investment and operation costs of the plan are also estimated.Finally,comparison between the regular design and the gas CCHP system are carried out.According to the comparison of the above two energy supply schemes,the main reason why the natural gas distributed energy application system is not accepted by users may be the high initial investment cost.But it has the unique advantages on energy efficiency,satisfying the user's special needs,and environmental protection.So,in the specific conditions of the user like hospital,the advantages of the gas CCHP system can get full developed.Therefore,the distributed energy system needs more time and experience to catch up with the world's advanced countries in research and development.
