The ASHRAE HVAC Duct Sizer app is a tool for calculating HVAC duct sizes using the constant friction method. It allows users to determine duct dimensions based on airflow, velocity, or friction loss.
It offers three main modes: 'Size by Airflow' to calculate dimensions from airflow, 'Size by Dimensions' to analyze existing ducts, and 'Range of Duct Sizes' to find sizes within specific friction loss and airflow values.
Yes, the app supports rectangular, round, and oval duct shapes. You can also specify air temperature and pressure for more accurate calculations.
Yes, you can choose to display all values in either English (IP) or Metric (SI) units, making it versatile for international use.
You can email all inputs and results directly from the app. The email includes both HTML text and a .CSV attachment for easy import into spreadsheet software.
The app is available for iPhone, iPad, and iPod touch, and it adjusts its screen size accordingly for optimal viewing on each device.
ASHRAE HVAC Duct Sizer is a paid application, priced at $5.99. It does not feature in-app purchases or advertisements.
The app was last updated on February 17, 2023, indicating ongoing support and potential for future improvements.
