i have a tstat and compressor from a freezer

I have a tstat and a compressor that i cut out of a working deep freeze. who has the brilliant idea on how i can cool my cab with this shit.

mucho thanks,

You're still missing quite a bit of other stuff. A radiator coil for heat exchange, for one.

Should've just made the deep freeze into a grow box and knocked about 7/8 of the refrigerant from the tank so it wouldn't get lower than 60 or so on quarter power. Less effort.

i tried . it was too small unfortunately. i was thinking of getting some copper tubing from the store and soldering them back together, and getting it charged. how much do you think is involved with that?

Hey, it's not worth it. There is some real heavy thermal math and purchase 2 new different types of coils to get a controllable cooling machine. Best bet is to get a $25 dollar window unit at a garage sale this weekend.

To save you guys some trouble. Taking 7/8 of the coolant out of a unit, freezer, or fridge will just make it freeze up and ruin it if you let it run long enough.

good to know. more along the lines of what i was thinking, as far as it being not really doable

We did this at McKesson Pharmaceutical plenty of times. Those freezers are still running to my knowledge.

And removing that much coolant won't make it freeze. In fact less coolant = less heat transfer = warmer internal temps = No freezing at all. Ever replace your car's refrigerant? When it's low, the AC doesn't cool as well as it should but the entire system still works. The '98 Taurus I drive has been like that for years, all the equipment still works, I just haven't had the money to replace the broken line and get the R134a recharged.

Read about coolant.

I have done a/c worked for years. like 10. It is true, when a unit is low it will not cool as well. Remove like 10 or 20% if you want it to run not as cold. If you remove 7/8 of the coolant there is no doubt that it will completely freeze up. Removing refrigerant like this would seem to make sense to the average person, it is simply untrue. Freon and its forms will instantly freeze at this low of a level. "less coolant = less heat transfer = warmer internal temps = No freezing at all" is not true even a little. It has some properties that you are unaware of.

What happens to a liquid (freon) that gets really really cold when you vaporize it in the valve? It will freeze up. It is one of the properties of it.

It doesn't freeze if you maintain proper pressurization inside the system. Remember that gases act differently from the norm at different pressures. Knocking out the freon in a system and replacing it with compressed oxygen at higher pressures will prevent the freon from ever freezing to begin with.

We use Freon-like substances in generating one form of concentrated solar power. Freon may act like you say it does in one instance, your instance being HVAC, but in many other instances and applications of freon and refrigerants in other fields of science, using different variables produces wildly different results.

Like lasers, for example. We cool our new high-power solid-state lasers with a R134a and Novec1230 mixture under high pressure. Moves like sludge but the heat transfer properties are ungodly.

I agree with you about adding another substance. You should tell people hat instead of just saying, 'well just let out 7/8 of the gas.' Not good for them and when they screw up their stuff because of it.

That sounds like some cool stuff you are playing with....LASERS! Fuck ya!

Let it be said that most should not touch freon.

True I should've mentioned adding oxygen or other lighter gases into the system.

Not to mention the $10k bounty/fine on anyone purposely venting freon into the atmosphere.

Lasers are fun! Watchin 'em cut 1 inch steel is a trip.
