A construction supervisor might want to ex amine the piping and ductwork in isolation to ensure that there are no interferences that will create costly conflicts during construction. HVAC Duct Construction Standards Public.Resource.Org 1.0 DUCT CONSTRUCTION. Ductwork and supports shall conform to the HVAC Duct Construction Standards, Metal, and Flexible, Second Edition, 1995. Where fittings of configurations not shown in the HVAC DCS are shown on the contract drawings, they shall be constructed as though they were therein. HVAC Ducting Principles and Fundamentals PDHonline High Velocity Duct Systems: High velocity (HV) duct systems are characterized by air velocities in the range of 2500 to 3500 fpm. Low velocity ductwork design is very important for energy efficiency in air distribution systems.

Data from the 2012 mercial Buildings Energy Consumption Survey (CBECS) shows that the United States consumes 6,963 trillion Btu of energy generated for commercial buildings. ANSI SMACNA 006 2006 HVAC Duct Construction Standards Information Required for Duct Construction 1. A comprehensive duct layout indicating sizes, design airflows, pressure class, and routing of the duct system. 2. The types of fittings to be used based on the designer's calculations of fitting losses (i.e., square versus 45 ° entry taps, conical versus straight taps, etc.). HVAC How to Size and Design Ducts cedengineering most cases the air in a duct is assumed to be incompressible, an assumption that overlooks the change of air density that occurs as a result of pressure loss and flow in the ductwork. In ductwork, the law of conservation of mass means a duct size can be recalculated for a new air velocity using the simple equation: V 2 = (V 1 * A 1) A 2 Duct dimensions on the drawings W X H or H X W HVAC R ... If a 12x6 duct is drawn on plan, then the width is 12 (the duct size "seen"), and the height (not seen) is 6" deep into the page. That same duct in section, you would "see" the 6" duct and the 12" would be assumed, so that duct would be called 6x12. HVAC Design Manual WBDG Whole Building Design Guide VA Standards are the culmination of a partnership among the Department of Veterans Affairs (VA), the VA Administrations, Program Officials, Clinicians, Industry, Academic and Research Organizations, Expert Consultants, and the Office of Construction and Facilities Management. Drawing HVAC Ductwork Chief Architect To draw HVAC ducts From the menu, select CAD> Lines> Draw Line and draw a standard CAD polyline where you want your ducts to be. Note: Molding Polylines generated from CAD lines will generate out to one side of the drawn polyline, typically to the right. For this reason it's advised to draw your CAD Lines in the same directions. 5.23.31 – HVAC DUCTS DESIGN AND CONSTRUCTION STANDARD SMACNA HVAC Air Duct Leakage Test Manual. Repair leaks and repeat tests until total leakage is less than 1% of system design airflow when the system is pressurized to the design duct pressure class rating.

Designing a duct system is important but there are a few critical steps that come first. Number one is the heating and cooling load calculation using a protocol like ACCA's Manual J or the ASHRAE Handbook of Fundamentals. You've got to know how much heating and cooling you need for each room (in BTU hr). 2018 HVAC Design Calculations ASHRAE The main objective of the HVAC design calculations project is to provide correctly sized heating, ventilation and air conditioning systems for the building. The team is to calculate heating and cooling loads and design the selected HVAC system for the building, while demonstrating compliance with the latest editions of ASHRAE Standards 55, 62.1 ...

Code Changes for Duct System Standards You Should Know It’s not enough to install ductwork and simply assume it’s good to go. If the ductwork doesn’t meet minimum standards for leakage, the performance of the entire HVAC system – and the building itself – could be in jeopardy. Currently, ASHRAE 90.1 recommends that 25% of a newly installed duct system be tested for leakage.
