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

Re: Finding temperature at Evaporator entrance
'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
