A discussion came up about sizing an airconditioner for a
computer/equipment room.

I suggested simply measure the current and voltage applied to the room
to determine power consumed (and average over some time) and this will
be the heat/energy that needs to be removed.  (Unless there are cables
that transfer the power out of the room)

My collegues indicated that not all the power consumed by the
processors and other hardware is converted into heat.  The energy is
converted into work done by the processor.

My understanding is that this is not the case and all the work done by
a processor and other hardware must be converted into heat (or light
which is still heat, or movement but when anything that finally comes
to rest must have converted its stored energy to heat via friction)
otherwise it is kind of 'disappearing'.

Am I off the mark here.

Justin
