ASHRAE HVAC Duct Sizer is a professional utility that functions as a digital replacement for the traditional Trane Ductulator. It enables HVAC engineers to calculate duct dimensions, airflow, velocity, and friction loss using the constant friction method. ## Key Features - **Size by Airflow**: Calculates exact and rounded duct dimensions based on total airflow, aspect ratio, and either velocity or friction loss. - **Size by Dimensions**: Analyzes existing duct systems by deriving friction loss from input dimensions and airflow or velocity values. - **Range of Duct Sizes**: Displays a range of duct sizes that fit within specified minimum and maximum friction loss and airflow bounds. ## Who is it for? HVAC engineers and mechanical contractors. ## Links - [App Store](https://apps.apple.com/us/app/ashrae-hvac-duct-sizer/id1273371824?uo=2) - [Google Play](https://play.google.com/store/apps/details?id=com.Energy4You.DuctSizer&hl=en&gl=us) - [Full Intelligence Report](https://marlvel.ai/intel-report/business/com-ashrae-ashraeductsizer) --- *This is an overview report.
