Pressure/temperature question about HVAC

[stryped]

I have been reading about hvac and have a question. I downloaded a neat app where you can input the refrigerant type, (say r22) and the low side pressure as well as the suction line temp, and it will give you the superheat of the refrigerant. Is there a way to figure out if a person installed a larger or smaller evaporator, how that would effect the superheat compared to the baseline?

Is there a way to figure out if a person installed a larger or smaller evaporator, how that would effect the superheat compared to the baseline?

The best way to figure this out is to either set up a thermodynamic model of the refrigerant cycle and take a look at the effect, or potentially utilize software which automates this analysis in an HVAC context.
