Well in a window unit the motor and heat exhaust are already outside,
so they cant add to the heat load of the room/
These drag around have all that noise and heat producing stuff
indoors, just that alone would cut efficency.......
I understand all that. But the EER is supposed to be the cooling
output divided by the energy used. And one would think that there
would be a uniform method to calculate it as it's the core of the
energy efficiency ratings.
