Duh. WAKE UP. The refrigerant is hot or warm in the orifice in the choke
point. It's still compressed there. Ain't no way ice is going to form
there.
Debris blocking it maybe; ice - NO! Only when the refrigerant exits the
choke point and begins to expand does it get cold enough to freeze water.
This happens AFTER the choke point and not at the choke point.

Is everybody on RBC stupid? Are they all Bruce in Bangkok clones or
something?

Here ya be:

"Moisture in a refrigeration system, directly or indirectly, is the cause
of
most problems and complaints. First, moisture can cause freeze-up in a
system.
Moisture is picked up by the refrigerant and transported through the
refrigerant line in a fine mist, with ice crystals forming at the point of
expansion."




Ah HAH! The point of expansion - EXACTLY! The refrigerant only begins to
expand AFTER the choke point. Up to the choke point, the compressed
refrigerant is actually warm. After it gets past the choke point it can then
expand and become cold as it expands. If you look at the evaporator you will
see a couple of interesting things. The large diameter copper tubing from
the compressor chokes down to a spiral of very small diameter copper tubing
(choke point) which spirals around the larger copper tube. The whole
freaking thing has warm refrigerant inside...

Willie-boy it is a crying shame that you don't know anything about
refrigeration systems, or physics for that matter. The temperature of
a gas decreases at the point the pressure drops. Not at some point
downstream of the orifice (not "check point, you fool) and water
freezing and blocking the system at that point is a common problem in
refrigeration systems.

Only AFTER the choke point where the refrigerant can begin to expand does
the evaporator get cold.

Once again, you don't know what you are talking about. The temperature
decrease is AT the orifice, not downstream of it.


Willy-boy you are not only demonstrating your ignorance of fridge
systems but you are demonstrating just how big a fool you are.

You voiced your opinion about osmosis - Wrong. Next you try to recover
your credibility by talking about fridge systems - Wrong again.

I wonder whether you will ever be right.
