Subcooling is way high -- Need Advice!

And i wish to reiterate, this is a resi system ..not a system subject to possible flooding like a chiller or other indirect refer system.

Yeh vacuum is a good insulator...but even celestial bodies experience heat gain in outer space.

I was talking to payson a lot when he was doing that test.

In a system you don't have that large of an amount of water sitting in one place. Just a few drops collecting here and there. And it freezes up much faster then what the video first implies.

In plain English since there is admittedly usually very minuscule amounts of water in a system under evacuation: It stands to reason that the larger volume of matter surrounding the moisture would be an enormous heat sink disallowing the moisture to phase change fusion to ice. There would be too much heat in the volume of the surrounding substance to give up that much heat to allow the change to ice.

One of the basic laws of heat transfer state quite simply that heat travels from one mass of a higher temp to a mass of a lower temp until equilibrium is reached.

With that, it would be improbable that the moisture would continue to draw heat from its much higher volume surrounding with out vaporizing long before equilibrium could be attained.

The math also bares this out.

No clover, or 5646 which ever one you are. Only the contact area of the mass touching the moisture could transfer any heat. As a vacuum does not transfer heat.

Payson used too much water. So it doesn't show real well how water can freeze during a vacuum.

There was ambient temps that contributed to. The length of time it took for the ice to form
HAd he used an insulted continued the results would have been diff.
If the anoint of water was less it would have boiled off in a closed system.

That isn't what u said in an earlier post.

You said heat was conveyed by radiant transmission.
The moisture is in contact way either internal surfaced or oil.
Either of which will conduct heat from comp shell and tubing.

I would also point out that
inert gas sweeps subtracts from your argument.

Clover/5646.

Why are you stuck on moisture only being in the compressor.

Moisture in the line set or anywhere else WILL freeze.

Yes radiant heat can travel through a vacuum.

You saw the bid. The water froze.

unless I can be in two places at the same time, you got a case of mistaken identity.

haha. changing the subject to get away from the real issue. Pretty sly, but I don't play that.
I didn't come here to argue.
I wanted to contribute to this conversationt in your discussion with the gentleman about vacuums.
But you have mistaken me for
Some one else.
Not very fair to me isit?

You keep only talking about the compressor. Moisture lays in other areas, besides the compressor.
