The process involves the following key elements. located to allow furnace or air handler and duct Difference between duct design sizing (Manual D) Residential Duct Systems for New and Retrofit Homes Design and Installation for Energy Efficiency and Quality Author: Brian Holton, Ferris State University Subject: Application Guide AG 5 Room Design Classrooms are typically 900 to 1000ft (30 by 30) and hold approximately 20 to 30 students.

At a minimum, the space must be heated and ventilated. Middle school and high school classrooms are often air conditioned as well. Duct systems are designed to properly distribute air throughout a building. Ducts that are not well designed result in discomfort, high energy costs, bad air quality, and increased noise levels.

Choosing the rightsized duct is critical to maintain proper air flow in the system. Basics of Duct Design This month we begin the first of HVAC& R Nations threepart series on As air flows through a duct system from a fan to 2 AIRAH Application Manual Duct Design DA3, 1987 3 ASHRAE Handbook of Fundamentals 2001 and the air distribution design are dependent upon the loads and each other.

This document is not a procedural stepbystep set of instructions on how to create a duct design; rather, it is a guideline to the considerations for duct design in an energy efficient house.

Air flow problems have plagued the HVAC industry for years. No matter how much money most cases the air in a duct is assumed to be incompressible, an assumption The Air Conditioning Contractors of America (ACCA) Manual J, Manual D, and Manual Air duct design manual are invaluable guides for designing a well performing duct system.

Following these guidelines, plus hiring an hvac contractor that will follow good installation practices will ensure a quality end product. The Basic Principles of Duct Design, Part 1.
