Thermodynamics / Q = mC⌂T equation in air application

1. The problem statement, all variables and given/known data

If you have a radio equipment cabin that has a heat load of 15kW and you wish to stop the temperature becoming more than 15°C hotter than outside, how much ‘free air’ (outside/atmospheric air) needs to be circulated inside the cabin per hour?

2. Relevant equations

Q = mC⌂T
C = 1.007
⌂T = -15

3. The attempt at a solution

I don’t know how to relate the m (usually a mass, right?) to a volume of air, as I assume that is the equations equivalent.
I hope that makes sense…
