The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has introduced an application for Apple's iPhone, iPod Touch, and iPad intended to make ventilation rates easier to calculate in the field.

The ASHRAE Standard 62.1 app performs 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.



The ASHRAE Standard 62.1 app also can be used to determine compliance of simple ventilation systems (single-zone, 100-percent outdoor-air, and changeover-bypass variable-air-volume) as well as more complex ventilation systems (single-path and 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 e-mail inputs and results for use in a spreadsheet at a later time.

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.

Available for purchase through Apple's online iPhone App Store, this app was developed for ASHRAE by Carmel Software Corp., a firm specializing in the development of engineering and scientific mobile and tablet software applications.
