ON OPTIMISATION OF VARIABLE AIR VOLUME VENTILATION SYSTEM DESIGN
Abstract
The questions of aerodynamics in ventilation systems with variable air volume are consideredon 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.
Keywords: hotels, energy saving, ventilation system with variable air volume (VAV), looped
ductworks.
