Dear sirs:

I am Mechanical Engineer working in Air Conditioning project.

In order to conclude a preliminar cooling looad estimation, for a room containing a 100 KVA digital broadcasting transmissor, I need estimate how much heat that kind of equipment realease to the surrounding space.

Could you give me an approximate heat release quanty?

Thank you,

schola

Can you tell us the transmission power? A 100kw AM signal? Or ??

I don't think that an estimate is the appropriate approach. A modern digital transmitter should be fairly efficient. But this means that you get rapid changes in the waste heat as the efficiency gets closer to 100%. As an example, 95% efficient would have five times the heat of 99%.

Also, there may be failure modes to be addressed.

You could probably look it up on the specification for the system. If not, then contact the OEM (Nautel or whomever).
