Originally Aired 07/20/2022 Viewers can take a brief quiz based on this webinar to earn 1 AIA Learning Unit (LU): https://www.proprofs.com/quiz-school/... Download the presentation slides here: https://bit.ly/AirFlowSlides Presented By: Todd Yates, P.E., TBE, CxA, Synergy Test & Balance A multi-floor university building project has central AHUs serving VAVs with induction diffusers. Because airflow at induction diffusers cannot be measured directly with a flow hood, instead they are measured by pressure drop at factory-installed ports. Initial work showed that VAV traverses were significantly different than induction diffuser readings. Resolving this conflict required input from the owner, designer, contractor, equipment manufacturer, and Cx provider. Learning Objectives: -Explain the operating principles of induction diffusers -Describe issues related to balancing induction diffusers -Discuss effective coordination with project stakeholders on technical issues and expectations -Describe alternative methods of measuring airflow in induction diffusers Sponsored by: Evergreen Telemetry: Evergreen Telemetry manufactures the unique Wrist ReporterTM, a 6-in-1 meter for Air & Water Pressure / Velocity / Flow / Temperature / Humidity / CO2. The patented Wrist ReporterTM is used for air balancing, commissioning, and troubleshooting in commercial buildings, cleanrooms, and residences. The Wrist ReporterTM displays real-time results from as many as ten wireless sensors at ten different locations. Applications include duct traverse, flow damper setting, ventilation calculations, duct pressures, room-to-room pressure hierarchies, coil performance testing, hood certification, and wireless data logging. This high-productivity instrument makes TAB and Cx Faster, Easier, Safer. Save the date for AABC Annual Meeting on October 12-14, Hilton Head Island, SC. Visit www.aabc.com for additional information.
