one CFPP MV electrical panal room of a industrial building having the size of 10Mx18Mx4M. The panals heat load for electrical equipment is 54-KW.
How much will be the total cooling requirement ?.

air con calculation looks ok. What are the chances of modifying it to work for a substation, where
the amount of DOL drives, amount of free standing VSD drives of different KW ratings and soft starters are installed. Therefore taking into consideration the heat generated by each of these units.
sub station will have no windows and fire proof door [steel/flameproof coated wood]
one to consider all drives running 24hrs.

I hope, we must consider the volume of the room in calculations. Since heat transfer coefficient value for window is higher compared to bricks wall, we shall consider the windows in all directions.
