Hi friends,
I've read a sentence in a book and I ask you to explain it more for me if possible.

I know superheat at outlet of evaporator includes "Static superheat + opening superheat".
And sources say that static superheat related to how loose or stiff is spring of expansion valve.

I do not understand this sentence :"if the system condensing pressure is higher, the pre-set static superheat will become lower and vice versa"
Source : SWEP hand-book

I can understand that static superheat is related to spring of expansion valve, It is very clear but what is relation of static superheat and condensing pressure ??

Sincerely yours.
