Tune in to watch Dwyer Instruments, Inc. on Inside the Blueprint TV show. Airing on Fox Business Network on Sunday, October 28th at 2:30pm (CST), the show will introduce the SMART Air Hood® Balancing Instrument and the ways in which this innovative product improves the process of balancing HVAC systems.
The objective for this writing is to inform HVAC technicians and contractors about the limitations of testing equipment currently used for testing, adjusting, and balancing HVAC systems. The need for more accurate instruments is immediate as energy programs are moving toward net-zero energy building efficiencies.
Air balancing a distribution system is needed to properly direct the air flow in order to optimize the system’s design. Flow rates are tested, adjusted, and balanced as cubic feet per minute (CFM) or cubic meters per hour (m3/h). There are two traditional methods for balancing airflow at the terminals. The first is sequential balancing, which involves setting the zone and branch dampers in sequence. However, the most common method of air balancing is called proportional balancing.
