Central Air Conditioning Energy Management System Design And Realization

This thesis analyse the present situation of central air conditioning monitor of energy saving system in the background of developing of central air condition monitor system and related technology.the dissertation introduces a large-scale central air conditioning monitoring of energy saying system which name is CAC-IEnet based on BACnet/Web service technique ,it monitors and controls the real time measurement of temperature,humidity,pressure,flow and the other power parameters of the central air-conditioning system,the administrator can monitor the operation and environment conditions in the air-conditioning system by the web services.The overall aim of the system is to build a scalability and opening system platform,so we can achieve the combination and interaction of central air conditioning device,and share the imformation with outside through each other.This thesis introduces the developing situation of this system,intergrate with the character of BACnet,propose the principle and method of the development of system .This thesis propose the frame and struct of the design of system after the analyse of requirement and data ,and then analyse and design the function struct detailly, and then describe the realization process of the technology of .NET platform and database SQL Server2005,at last we test the system which have realized in this project,form the result , it show that the system can reach the aim of design and fulfill the need of people,except that,the system also can reach the manage of saving energy,through the using of BACnet portocal ,the system which design and develop based on BACnet have very strong realization meaning and broad prospects.
