ACGIH® PRESENTS MANAGING ENERGY IN VENTILATION SYSTEMS:
VARIABLE FREQUENCY DRIVES (VFDs) WEBINAR
— September 11, 2008 — ACGIH® will present the Managing Energy in Ventilation Systems: Variable Frequency Drives (VFDs) webinar on November 19, 2008 at the following times:
2:00 p.m. – 4:30 p.m. Eastern Time
1:00 p.m. – 3:30 p.m. Central Time
12:00 p.m. – 2:30 p.m. Mountain Time
11:00 a.m. – 1:30 p.m. Pacific Time
Ventilation systems are inefficient by nature. Over 40% of the horsepower (HP) in most plants is expended on powering fans and pumps. In ventilations systems for large buildings, variable frequency drives (VFDs) on fans will save energy by allowing the volume of air moved to match the system demand. Current VFD costs have decreased in recent years to a point where they can be incorporated into almost all ventilation designs. They also have flexibility of control and offer considerable electrical energy savings through greatly reduced electric bills. VFDs also have special requirements to provide stable operation and to maximize energy savings potential. This webinar will provide key information regarding the use of VFDs as well as how they work to reduce plant operating costs. Practical examples will be demonstrated during the live webinar and attendees will have an opportunity to ask questions in a real-time setting via a chat feature.
After participating in this webinar, attendees will be better able to understand:
- How the use of variable speed systems can help a large building save energy
- How VFDs can be used for improved system reliability and system life
- How system and fan curves interact
- The system curve in a variable pressure system
- How air density affects fan and system curves
Industrial Hygienists, Occupational and Environmental Health Professionals, Safety Professionals, Environmental Engineers, and Plant and Facility Managers should consider attending this important educational event.
ACGIH® is pleased to offer webinar attendees a new audio option. U.S. and Canadian attendees can connect to the audio portion of the webinar via the toll-free audio telephone link or listen to the audio portion through an audio stream directly through their computer. Other international participants can listen via the audio stream without incurring additional telephone charges.
