| Abstract |
The purpose of this study is to evaluate the performance of various control strategies in commercial buildings which have been operated by the variable air volume(VAV) system. Two buildings in Seoul were chosen for the field study. The one(D building) combined by LonWorks has the constant airflow of supply fan and the proportional control of VAV units(damper type). The other(S building) combined by DDC has the PI control mode of the supply fan and the floating control of VAV units(venturi type). In estimating thermal comfort and energy performance through control modes of PI, PID, and CAV in the supply fan, we could identify several energy efficient operating control strategies for the VAV system. |
