Actual Expansion Valve Process
I observe that the expansion process in Thermostatic Expansion Valve is not even close to isenthalpic process. The inlet to EV is around 16 bar 45 deg C and output of EV is around 3.5 bar 2 deg C both lying outside vapour dome in liquid region and in P-h chart the deviation from straight line is quite high.
Is there any parameter for defining effectivess of expansion valve or efficiency kind of?
Usually in what range this efficiency might lie in actual air conditioning processes?
Expansion Valve: Cross Charge - C3 Block type with 10 deg superheat design
