Hey, Fuckhead...
First, you have to understand the original posters question.
Second, you have to understand how a HVAC system operates.
Third, you have to understand heat gain.
Those are some of the items you need to know. Along with *common sense*
(which you obviously don't have), then you could figure out a competent
answer.
I would explain it to you... but it would be a lost cause, as some people
are just un-trainable. You and Stormy have this level of incompetence.
