Finding Temperature at stage four, Refrigeration Cycle

  1. Aug 15, 2013 #1
    Dear all,

    This is for a theoretical system, which is trying to represent an 'actual' vapour compression cycle.

    I have the pressure, temperature, enthalpy and entropy at stage four of a single stage cycle. Stage four is the stage where refrigerant leaves expansion valve and enters evaporator.

    Is it possible to find the temperature, T4? I know how to use saturation tables, but I think for the evaporator entrance they arn't accurate,, is there any other way of deriving this value? I would love to know.

    I have temps., press., entahlpys and entropys at all other stages of cycle so i assume there is some equation to get T4, in theory any way.
    Kind Regards
