Solves duct leakage control using duct seal class and duct leakage class!<\/span><\/p>\n

A companion to HVAC Duct Construction Standards \u2014 Metal and Flexible, this manual contains duct construction leakage classification, expected leakage rates for sealed and unsealed ductwork, duct leakage test procedures, recommendations on use of leakage testing, types of test apparatus and test setup and sample leakage analysis. Also covered are orifice flow meter design and valuable references for fluid meter instrumentation. This manual is referenced in ASHRAE\u2019s Energy Conservation Standard 90.1. Identified as DALT by some government agencies. Can be used for positive and negative pressure tests.<\/span><\/p>\n
