Even an approximation is hard to make.  One might think the simple math of  
"how much power is fed into the room" would do, but it ignores numerous  
factors that greatly effect the answer.  I can rattle off example after  
example, but it's unnecessary.  You'll need professionals to install the  
hardware, so there's no point not calling them in for a consult.

(And the elephant in the room no one has mentioned is "air flow".  Cooling  
capacity is only half the equation.  Air flow *volume* is just as  
important.)
