Ventilation
Sizing ventilation for electrical rooms
Electrical rooms need ventilation to limit heat rise around boards and drives. Undersizing shortens equipment life.
Heat load thinking
Consider transformer/drive losses and solar gains on the room.
Coordinate with the electrical designer.
Air path
Supply and extract positions matter; recirculation does not cool.
Filter maintenance access is essential.
Procurement
Specify fans and controls together.
NMF can include ventilation with board packages when the BOM calls for it.
