1 Introduction to AirCalc
Danfoss AirCalc is a dimensioning tool, specifically developed for
the dimensioning of Danfoss Air units and Danfoss Air Flex products.
Danfoss AirCalc calculates the pressure loss of your entire Air Flex
system, but also down to component level if desired. The program
also offers a suggestion as to which unit would constitute the ideal
choice based on entered data.
Based on the calculated pressure loss and the selected unit, a presetting is calculated for valves, the pre-setting of valve increments
for the selected unit, as well as the SFP value and energy consumption.
1.1 Start-up
Once Danfoss AirCalc is started up, the programme will immediately attempt to establish a connection to a Danfoss server.
If a network connection is found, the program will automatically
search for available updates. If an update is found for the programme, it will be automatically downloaded and installed.
If the programme is started from a PC without a network connection, the programme will search for a server for approximately 15
seconds and then start normally.
With the flexible report generator, print-outs can be fully managed
by the user so that the generated report contains only the pages
desired. This means everything from basic information to complete documentation, including all data sheets for products that
form part of the system.

1.6 Left Menu Set-up
As can be seen in the picture to the left, there are two small icons
in the top right corner: a thumb tack and an X.
When you click the X, the left menu will be closed until the mouse
is again led over the edge of its frame, after which the menu will
once again become visible.
When you click the thumb tack icon, the menu will close automatically once the mouse is directed away from the menu. This function is active when the thumb tack's tip changes position from
pointing to the bottom of the screen to pointing to the left.
2 Dimensioning
2.1 Dimensioning Menu
Once a project has been created, access is granted to the dimensioning menu on the left side.
The menu's individual options are explained in the following.
NOTE: The order for extract and supply does not matter, but these
should always be completed before calculating outlet and inlet.
