Finding temperature at Evaporator entrance

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

'in theory' the liquid entering the evap will be at suction pressure temp with the addition of any subcooling

although when I carry out physical checks when I decide where my inlet probe should go

I find someone keeps stealing my subcooling

have been blaming mr flashy gassy but would require a Mad Fridgie or Install Monkey to find the culprit
