Pressure/temperature question about HVAC

  1. May 2, 2017 #1
    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?

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

    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.
