App helps in evaluation of different fan specifications for a given application. Most manufacturers provide fan curve (Q vs H) and the operating point on this curve depends on the type of duct system, the average duct velocity, duct pressure loss and duct leakage rates. Thus selecting a right fan for the given duct system is very critical to the satisfactory performance and energy efficiency.

Fan properties:
Fans are categorized based on the type of flow. The flow can be either axial or radial by centrifugal action based on type of application. Fan specification data such as rotor diameter, fan rpm, motor power and flow rate at given static pressure need to be provided that will be evaluated against the given duct system.

Gas properties:
By default Air is used as gas medium and its properties are updated based on the input temperature. For gases other than air, edit the property data such as density, viscosity at given temperature.

Duct system
Users can choose any duct system based on cross section, class, size and material. Upon selection, app auto updates the duct leakage rates as per recommended standards. The total equivalent length data is used for evaluation of duct losses that includes resistance due to different duct fittings and terminal boxes.

Performance summary:
A comprehensive fan-duct system summary is displayed as shown in the screen shot.

App notes provide descriptions of different fan performance characteristics referred in the summary.

What's New

1. Modified screen layout with new tool bar buttons as shown screen shots.
2. Added additional button to facilitate quick computation while editing when virtual key pad is displayed. 3. Added a separate run button to execute fan spec model in order to avoid image interference with text fields.
4. App provides maximum air duct leakage rates under allowable standards for a given duct class and static pressure.
5. Updated duct system and app notes. Results are consistent with iOS app.
