| الوصف: | Traditionally the variable-air volume (VAV) system is used for demand-based ventilation. With VAV the air flow rates are controlled based on actual demand but at the same time the static pressure of the system has to be adjusted to a relatively high and constant value. The modern approach utilizes the model-based method, which offers a comprehensive system and controllability of the airflow distribution within ductworks. The intelligence of the model-based system is achieved by a computer model of the air flow dynamics within the entire ductwork. The system can therefore balance the air flow throughout the building whilst maintaining the duct pressure at an optimum low level, thus minimizing the fan power requirement and reducing the noise emission. During operating conditions, it is possible to maintain the pressure at as a low level as possible. This means energy saving in electricity consumption. Based on simulation, the electric energy consumption of the fans can be reduced by 25 – 55 % compared to the typical VAV system. |
