RE: Dew point / bubble point?

Answered

Hi, I was a little confused when watching your videos, you say to use dew point for superheat, and bubble point for sub cooling. 

But, as far as I see it, dew point would occur in a condenser, and bubble point would occur in an evaporator? Would it not? 

Any info greatly appreciated

I guess we know that superheat is measured after the saturation point, which will be close to the bubble point, so I can see the rationale there, but still confused as to why it’s called dew point in the evaporator / suction line?
