VAV SYSTEM PERFORMANCE SIMULATION WITH DIFFERENT DUCT LAYOUT

摘要

The duct static pressure reset (DSPR) control method was an energy efficient control method widely applied to VAV systems of commercial buildings. In this paper a VAV system simulation program was used to predict the system performance and zone air temperature of three kind layouts that were utilized to a typical floor of an existing building office in Hong Kong. The comparison of predictions of three kind layouts indicated that with the same DSPR control method the layout of the air duct might influence the fan control result and energy consumption.
