SUMMARY
The discussion centers on calculating the amount of atmospheric air needed to maintain a temperature increase of no more than 15°C in a radio equipment cabin with a heat load of 15kW. The relevant equation used is Q = mC⌂T, where C is the specific heat capacity of air at 1.007 kJ/kg·K and ⌂T is set to -15°C. Participants emphasize the need to convert mass flow rate (m) into a volume of air, utilizing the ideal gas law (pV = nRT) for accurate calculations. The conclusion is that determining the mass of air required per hour is essential for effective thermal management in the cabin.
