On optimization of variable air volume ventilation system design

The questions of aerodynamics in ventilation systems with variable air volume are considered on the basis of hotel building. The method of using looped ductworks for equalization of static pressure along the ductwork and for provision of optimal air distribution during the change of the load is given. Computer simulation of ventilation network of a dead-end and ring configuration is performed with SolidWorks Flow Simulation software package. The calculations show that loopback network of ducts contributes to air flow balance at the change of system performance. The assessment of the necessity to use VAV regulators in ventilation systems with variable air volume is given.
