Study On Optimization Design Of Energy Saving Technology For Typical Buildings Of Dalian University Of Technology In Liaodong Bay

In recent years with the country's attention to energy conservation,low-carbon building policy support to increase,around the new construction of the campus have many green low-carbon strategy.In the new university town development and construction and the new campus construction practice,the university teaching building low energy consumption design highlights many new problems,foreign developed country teaching building is in low energy consumption or zero energy consumption premise,equipped with good Ventilation and air-conditioning equipment,refrigeration and heating systems and other means,and China's low energy consumption of teaching buildings are often at the expense of the cost of comfort,or to improve the technical level and lead to high energy consumption counter-effect.Dalian University of Technology,Liaodong Bay campus as a "National Science and Technology Support Project" demonstration project,design and construction to ensure the advanced nature and forward-looking,using a large number of demonstration energy-saving technologies.Although the new energy-saving technologies have been used in practical engineering after repeated research,most of them are designed for the specific requirements of Dalian University of Technology Panjin Campus R&D or technical system optimization and integration of forming,before this Direct application of precedent.Dalian University of Technology,Liaodong Bay campus has been put into use for more than three years,but the energy-saving strategy adopted has not achieved the expected results,has not been field test,the use of the lack of in-depth analysis.In order to complete the research on the energy saving optimization design strategy of the typical teaching building of Dalian Polytechnic Liaodongwan campus,this paper relies on the"12th Five-Year" project "Cold Energy Low Energy Building Energy Conservation Design and Energy Complementary Heating Technology" In the first part,the author carries on the computer simulation analysis to the Dalian University of Technology,Liaodong Bay campus main building(five teaching buildings,one library,in the name of teaching building),and then examines the teaching in the transition quarter and the heating season twice.Floor physical environment data and energy-related data,the data are a typical teaching building envelope system heat transfer coefficient,building heat consumption,the typical space of the indoor physical environment data,and ventilation lighting system,double curtain wall systems and other systems related data.At the same time,some software simulation results were validated and a lot of data were obtained.Finally,by comparing the computer simulation data and the actual test data,the paper gives the feedbacks of the managers and users of the teaching building,and draws up the problems and shortcomings of the energy-saving design strategy and current usage management of the teaching building of Dalian University of Technology In view of these findings,combined with the characteristics of the school building itself to reduce energy consumption and increase the comfort of the feasible optimization design.It is hoped that this paper will contribute to the promotion of energy-saving technologies in the building energy-saving technologies of the typical buildings in Dalian University of Technology,and make some reference and reference for the design of low-energy buildings in the cold area.significance.
