چکیده
After introducing the central air-conditioning terminal units system, established a fuzzy control system based on Lonworks. System focuses on the design of fuzzy controller with intelligent nodes, Input signal of fuzzy controller were the concentration and concentration rate of CO2, output signal was the volume of fresh air change, designed a two-dimension fuzzy controller. Based on the search results table, select adjust the fan speed or adjust fresh air valve opening, so as to minimize the amount of fresh air and meet the demands CO2 concentration indoor, so as to achieve the objective of reducing energy consumption and improve air quality. Finally, the fuzzy control algorithm which offline calculated was downloaded to intelligent node, and through experiment verification of the control effect is good.
