Thank you guys!

@DangerMouseDom:
I selected the 01 orifice as It is rated for 1kW heat-load. I have looked up what cooling power this compressor offers at prefered temperatures and then selected the appropriate orifice for the TXV. Go with Plate HX, it has a fast pull-down in comparison to coax HXs.

TXV or TEV is selected by the gas you are intending to use and then you choose your nozzle / orifice by the cooling power or desired temperatures. For every gas there is a different TXV as the gases have different pressure-temperature corelation curve.
