ATLANTA - The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) made calculating ventilation rates a little easier with a new iPhone application designed specifically for an interactive calculation spreadsheet related to ASHRAE’s ventilation standard.

Developed for Apple’s iPhone, iPod touch, and iPad, the ASHRAE Standard 62.1 app allows for convenient calculations while in the field, performing the outdoor air calculations found in the Ventilation Rate Procedure and the interactive 62MZCalc spreadsheets contained in the ASHRAE User’s Manual for Standard 62.1, Ventilation for Acceptable Indoor Air Quality.

“As a leader in the advancement of the latest HVACR technology, it’s only right that we utilize the latest smart phone technology,” said Jim Fields, volunteer head of ASHRAE’s publishing activities. “This new application ensures that engineers in the field have instant access to the most accurate information without having to return to their office to perform calculations.”

The ASHRAE 62.1 app can also be used to determine 62.1 compliance of simple ventilation systems (single zone, 100 percent outdoor-air and changeover-bypass VAV) as well as more complex ventilation systems (single-path, multiple zone recirculating) and can operate in both IP and metric units. Other benefits include the ability to store and access multiple projects within the app and also to e-mail inputs and results for use in a spreadsheet at a later time.

The ASHRAE 62.1 app can be purchased through Apple’s online iPhone App Store for $19.99. The app applies to the calculations and spreadsheet in the 2007 standard and User’s Manual. When the documents are updated to correspond with new editions of Standard 62.1, purchasers will receive a free upgrade.

This app was developed for ASHRAE by Carmel Software Corp.
