If a refrigerator is used outdoors, in the summer.
The condensor on the back, is black tubing. As
we know, black absorbs heat from the sun shine,
which makes the compressor work harder.

Of course, that condensor can be painted. Which
color paint is coolest in summer, and works best
to release the heat from the refrigerator? White, or
silver?


Condensers and radiators are black for a reason. The darker object
emits/loses heat more efficiently. It also absorbs heat better but
when the source of heat is gone, heat will be released quicker. In
science class, teachers have been demonstrating the effect to students
for many years. In your case, I would leave the condenser black and find
a way to shade it from direct sunlight with something painted in a
light color. ^_^

There is even special paint for radiators, you don't want too thick a
coating.
