Research for Air Conditioning System Based on The LonWorks Syetem
Abstract：This paper briefly discusses that the status of the air conditioning control system
based on Lonworks technology.According to the characteristics of Lonworks technology and the analysis of the building automation air-conditioning control object,the design of central air-conditioning system overall school student dormitory is proposed by researching and the use of this method.Compared with conventional control,configuration, commissioning and maintenance of the Lonworks is more convenient.
By parsing Lonworks intelligent node hardware structure and composition of each module, for selection in accordance with the requirements of the hardware configuration of the control object,and design of intelligent valve module and temperature and humidity controller module. In the software design process, we focus on the advantages of fuzzy -PID control regulation, and from its program flow chart to achieve control in order to save energy. Finally, this paper also presents some problems that worthy of attention when introducing fieldbus technology in
medium-sized central air-conditioning control system.
The overall performance of the air conditioning control system is improved through this design, Lonworks technology shows its effectiveness and practicability, making building automation systems more intelligent.
