Avg. BTU Rating for Appliances (Microwaves, Refrigerators, Etc.)
(OP)
Does anyone know where I can find an avg. BTU rating for refrigerators to apply to my cooling loads? I've looked in the ASHRAE handbooks, but I can't seem to find anything.

I could only estimate the gain by determining the physical external area, then use a typical internal-external temp difference multiplied by the thermal transmittance value.
It wouldn't be much I guess, perhaps 20W/m2 of fridge area for internal at -20 c and room at 20C.
so for fridge at 2m high x 0.6x0.6 (we have small fridges in the UK) then =96Watts (excludes allowance for compressor COP etc) I would allow something like 150Watts to be on the safe side.
