Expansion valves
I was hoping that someone could explain in simple terms how a basic expansion valve works! also with respects to the equalising line, when it is needed and when to use internal equalising valves.
Also why when condensing fans start does the sight glass in a liquid reciever become cloudy?
Thanks alot!
