K-factor conversion table (Flow only)
The k-factor given by the equipment (k₁) is entered into the equation and the result (k₂) is entered into the VCH.
Example of calculation:
The k-factor data for the equipment is declared to be 5.6 based on liter per seconds [l/s]. You want the VCH to handle flow in cubicmeters per hours [m³/h].
On the second row you will find the equations for k₁ in [l/s].
In the first column you will find equations for k₂ in [m³/h].
k₂ = k₁ * 3.6
k₂ = 5.6 * 3.6
k₂ = 20.16
Enter 20.16 into menu point Set4 [
The VCH display will now show the calculated air flow in cubicmeters per hours. Remember to place the m
