October 2024 Meeting – High Induction Ventilation

TOPIC: High Induction Ventilation

Join us for an insightful presentation at the October meeting, where we will delve into advanced concepts of high-induction duct diffusers and their practical applications, as exemplified by NAD Klima’s cutting-edge solutions.

Our focus will be on demonstrating the efficiency of high-induction diffusers through a mixed experimental-numerical approach, highlighting their superior performance in energy consumption and ventilation effectiveness compared to traditional methods. By benchmarking five RANS models, we identified the most accurate turbulence model for assessing high-induction diffuser’s comfort parameters, leading to an up to 18.4% reduction in airflow requirements and energy consumption.

Additionally, we will explore how different perforations on the duct surface can significantly heighten airborne infection control, achieving up to a 30% reduction in the residence time of infectious nuclei. Our adherence to ASHRAE standards, including ASHRAE 62.1 and 129, underscores our commitment to delivering high induction solutions and optimized Ez values.

This presentation will offer a detailed analysis of how innovative diffuser designs and compliance with industry standards can drive improvements in both comfort and efficiency.

Recommended audience: Engineers, Contractors, Manufacturer Reps, Students, Building Owners
