The Engineering Mindset for a 15KW (with PHE) Capacity System , We used TE12 - Orifice 6 ( We didn't consider the Sub-Cooling caused by PHE + we weren't using PHE initially) Effectively System was delivering 10kw ODU with 15KW idu with TE 12 Orifice 6. @ 8psi Suction & 275psig Discharge. 1 system later failed as 2 cyclinders of compressor discharge reed went off, as soon as we enabled PHE,( may be or bcoz of TXV) Question is was the failure because of TE12 during normal Operation or the mismatch of PHE & TXV. Accurate Txv is TE5 Orifice 3. for the system (later as we considered additional Sub-Cooling)?

Great discussion on the function of the bulb...its pretty clear that if the valve gets stuck in the closed position, there will be no cooling even though the refrigerant in the bulb is expanding against the diaphragm (trying to open the valve).

Change of state begins the moment the refrigerant passes through the tx, not just at the end of the evaporator. There is one constant temperature for as long as the refrigerant is changing from liquid to gas.

Thank you so much watching this video. I Now understand Automotive type of expansion valve. Although it's very different it's also very similar. The automotive one does not have the capillary tube. It has a high pressure line and low pressure on the same block.

Very nice explanation of simple TXV. But would be nice to have quick overview of some variants, like what is the third port on TXV which connects directly to the suction line?
@teravolt6113
@teravolt6113 5 лет назад
It's the external equalizer line. Big evaporators need externally equalized TXVs because pressure drops considerably inside them, so the equalizing pressure is sourced from the evaporator's outlet rather than from the TXV's outlet.
