Calculation of Required Air Flow

In order to ventilate and cool inside the control panel and maintain the appropriate temperature,
you need to know the required air flow of the fan which meets the conditions.
Required air flow can be determined from the size, material and temperature of inside and outside of the control panel.
Please make use of it at the time of selection calculation or as a supporting tool when setting up.
Enter the setting value and click the "Calculate" button, then the results will be shown.

Material of the Control Panel (Note 1)   Iron
Location to Install  
Width of the Control Panel W: [m]
Height of the Control Panel H: [m]
Depth of the Control Panel D: [m]
Ambient Temperature of the Control Panel T1: [℃]
Internal Permissible Temperature T2: [℃]
Gross Calorific Value Q: [W]
Safety Factor (Note 2) Sf:  
(Note 1)
If the material of your control panel is not in the choices, Please contact Technical Support (Free of charge)
(Note 2)
When calculating required air quantity, it is necessary to consider the internal pressure loss.
Generally pressure loss inside the control panel is unknown, so the air volume at the operating point was assumed to be 50% of the maximum air volume, and also consider the safety factor Sf = 2.
