Type of article: Article

Summary

Points out that the mechanical and electrical components of the VAV unit are generally from variant manufacturers, hence, the two components may not match each other completely. Presents the definition of air volume calculation coefficient (Kv) used to calculate the air volume for the controller in VAV terminal units and the testing device and method for obtaining the coefficient. Analyses the cause for the difference in Kv of different VAV controller for the same box. By means of analyzing the impact of air supply pressure on the control precision of the VAV system, finds that the lower air pressure, the higher the lower limit of the effective VAV damper openings.
