Superheat

If you increase superheat(temperature ) in the refrigeration cycle will the (superheat)pressure increase, too?

No?

are you increasing the suction line temp or the suction saturation temp? stop thinking in terms of pressure

My Old Guy told me to think about everything in terms of temperature & not pressure. Doing it that way you'll be able to work on any refrigerant, because the evaporator & condenser temperatures aren't going to change much for air conditioning.

But superheat is literally a function of temperature and pressure?
I'm not understanding how someone can think of everything by temperature and ignore pressure in refrigeration?

Sorry, I wasn't clear. Temperature & saturated temperature might be clearer. No matter what refrigerant we're using, a saturated condensing temperature of 25° is a problem, whether it's 87 PSIG (410A) or 48 PSIG (22) or however many thousands CO₂ will be.
