Electromechanical Transformation Of Existing Buildings Based On Engineering Examples

From the end of the 19th century to the beginning of the 20 th century,China has built a large number of industrial,public and residential buildings,plus historical buildings left over from the early years.These buildings can meet or continue to be used in structural safety.The economic cost and social benefits of the transformation are far greater than the costs and benefits of dismantling and rebuilding.However,due to the long time,some equipment facilities and line pipelines have been unable to meet the normal use,or the relevant energy consumption indicators and safety conditions have been unable to meet the requirements of national regulations,so how to improve their quality of perception,use functions,reduce energy efficiency and Ways to improve safety,including how to mechanically engineer it,are especially important.Based on the existing examples of construction projects,this paper finds out the existing problems of existing buildings through on-site inspection and inspection.Based on the analysis and research of the data,this paper summarizes and summarizes the relevant data and technical standards.For the three sub-projects of air-conditioning engineering,electrical engineering,water supply and drainage engineering,the reform proposals with practical guiding significance in terms of improving energy efficiency and increasing safety.Air conditioning works.Through the cold heat source system,the transmission and distribution system,and the end system,the energy-saving transformation is carried out,and at the same time,the enclosure structure is modified to improve the insulation performance of the building and improve the energy-saving effect of the air-conditioning system;the fresh air system and the smoke-proof system are upgraded and the air is improved.Quality and escape time after fire.Electrical engineering.Through the upgrade and transformation of light source,transformer,line,elevator,energy efficiency monitoring system,improve the efficiency of building electrical energy use,improve the power saving effect of electrical engineering;through load calculation,line laying and insulation,leakage protection,equipment grounding,building lightning protection,Backup power and uninterruptible power supplies to improve the safety of building electricity.Water supply and drainage works.Through the use of water-saving appliances,rainwater collection system,hot water pipe insulation,drainage pipe replacement,improve the water-saving effect of building water supply and drainage;through strengthening fire system water supply,drinking water quality,hot water system control,drainage system water seal,pipeline Spacing to increase the safety of building water.Through these transformation measures,it can effectively improve the cooling effect of air conditioning system cooling,power consumption,water consumption,etc.,and improve fire safety,air safety,electricity safety,lightning protection safety,water safety,and make the reconstructed building more Energy saving and environmental protection,people are safer and more comfortable to produce in the building.With the development of materials and processes,the research of transformation will be continuously improved.Only the transformation of each division project,the transformation of the main structure and decoration project,the architectural history and the surrounding conditions of the building can be more perfect.Reconstruction project.
