Numerical Simulation and Optimization of Local Resistance Characteristics for Energy-Saving Operation in H-Type Ventilation System

The energy consumption of industrial ventilation systemsVentilation system plays an important role in industry building systems. The resistance of local components accounts for a large part of the total resistance of industrial ventilation systems. Reducing the resistance loss of local components is of great importance for improving the energy efficiencyEnergy efficiency of a ventilation systemVentilation system. In this paper, ANSYS Fluent 18.2 software was used to research the resistance characteristics of the ventilation system with different flow deflectors. The results indicated that adding flow deflectors at the tee could maintain the air volume balance of the ventilation system, reduce the resistance loss, and increase the maximum reductionReduction of resistance rate by 19% in the ventilation systemVentilation system. This study is expected to optimize the low-carbon and energy-saving operationEnergy-saving operation of industrial ventilation systems.
