Hi all, we need to cool down a server room. It is known that we need 3500 BTU every KW of computers (plus some more for the room form factor, ok)
I was reading that conditioners nowdays have an EER rating of 10, that is they draw 10000 BTUs for every KW of consumed electricity. Hence, I computed that we would need 350W to cool down 1KW of computers.
However, our electrician tells us that this is not true, because the power drawn by conditioners is in facts much higher than what is stated on the box. He says that a fully running 12000 BTU conditioner actually draws 3 KW, not 1.2 KW like it is written on the box.
If this is true, then we would need 875W of conditioners in order to cool down 1KW of computers, instead of the 1.2 KW declared on the conditioner specs.
This would be a problem for us, because we would then need to place new electric cabling in order to bring more current to the server room.
Do you confirm that conditioners are so much more inefficient than what is stated?
Oh, another question: where are these conditioner watts dissipated? I hope that is on the external fan unit, not on the in-room AC split, otherwise we would need to also cool down those watts, and the needed conditioning power would be immensely superior...
