Full Description

This paper discusses how dual-duct variable-air-volume systems, properly designed and controlled, can lower first costs and operating costs using a variety of strategies including:

Twin-duct system architectureDual motor fan drives with inlet vanes in lieu of a single motor with inverterHeating/cooling changeover of the traditional hot ductDirect digital control of terminal unitsPrecise control of duct static pressureElimination of return air fan

By utilizing the above concepts and a computerized design program, a system canbedesigned
that retains the low maintenance benefits of traditional dual-duct systems as well as providing the low noise, low cost, energy-efficient systems required to make todayâs building profitable.
