The 15 degree difference does not pertain to indoor versus
outdoor. It
pertains to the indoor air temperature entering the
evaporator unit compared
to the cool air leaving the evaporator unit. This indeed
depends somewhat
on the outside temperature, but not as much as you might
think. It also
depends on the airflow speed. I generally see it run from a
15-degree
difference to a 20-degree difference.
That is, if the temperature of the air in the house is 75F, then the
temperature in the plenum entering the cooling chamber is
75F, and then the
temperature in the air plenum right after the cooling chamber
should be
between 55F and 60F. Note, the temperature at the grills
where the cold air
enters each room will be a bit higher.
