Paper Title:
Application of Fieldbus and Frequency Conversion Technology in Air-Condition VWV System
  Abstract

This paper presents a method which uses LonWorks control system and frequency converter in Central Air-Condition chilled water variable flow system. In this system, the output of frequency converter can be altered by augmenter PID control rule which is used in control of invariable difference in temperature between water supply and backwater, and the rotating speed of water pump can be changed correspondingly, so when the user load is small ,the electric energy consume can be reduced. The effect of energy-saving was visible comparing with the conventional Air-Condition chilled water constant flow system.
