The Green Impact of Efficient Duct Design An Aug 2009 article published in the RSES Journal, authored by Chris Van Rite presents - Proper sizing and installing ductwork can make an HVAC system and the system owner "green" in more ways than one.
Air Flow is Critical To HVACR System Performance, An April 2008 article published in the RSES Journal, authored by Chris Van Rite presents Understanding the benefits--and drawbacks--of flex ductwork are critical to creating efficient HVAC systems.
True Cost of Flex, A summary flyer for a NATE Certified Program (#7096-0004, 1 hr.) presented by Chris Van Rite sighting recent Lawrence Berkeley National Laboratory and Texas A&M research results of serious air flow inefficiencies of flexible duct.
What Homeowners should know about the Hidden Cost of Flex and how using steel air distribution systems can save them money.
Static Pressure Losses in 6”, 8”, and 10” Non-Metallic Flexible Duct A Texas A&M study measured airflow static pressure losses through non-metallic flexible ducts.
Changes Relating to January 23, 2006 NAECA Update The National Appliance Energy Conservation Act (NAECA) of 1987 established among other things minimum Seasonal Energy Efficiency Rating (SEER) for A/C equipment. The minimum SEER required by NAECA since 1992 has been 10 SEER. On January 23rd, 2006 the NAECA minimum SEER increased to 13 SEER.
Stakeholders in Residential Energy Code Compliance NAECA provides that Federal standards for certain products preempt standards for those same products in state and local codes under certain conditions.
COMPARATIVE STUDY: CFD Delta P VERSUS MEASURED Delta P FOR 30% FLEXIBLE DUCTS A Texas A&M paper prepared by sighting results that compared to the straight ducts, the compression in flexible ducts results in increased pressure loss thus increased energy consumption.
A Comparative Analysis of CFD Delta P versus Measured Delta P for Maximum Stretched, 4%, 15% and 30% Compressed 6” Diameter Flexible Ducts A Texas A&M paper - Fully stretched, 4%, 15% and 30% compressed 6” flexible duct configurations were simulated using CFD software under various volumetric air-flows.
