Spare Freezer...

[hellrazrblade]

Okay, i have an old deep freezer that just isnt working like it should (only drops to like 18f/-8ishC) It is the kind with the door on top. It about 3'W*3'D*3.5'H if im guessing right. Is there anything of use in there or is it just going to end up in the trash?

LoL Yea... you can buy or find replacement parts for it and have one kick butt water resevoir...

[ComputerJLT]

it probably either leaked out some refrigerant which means you have a leak or the compressor isnt working like it should......

either way it will involve emptying the system looking for and fixing leeks and then testing and filling.... If you have the stuff to do it or know someone who will hook you up for cheap than its really easy to fix ;)

yeah, im gonna try fixing it, but this baby is like 20 years old (fake wood top and all baby!) so i'm mainly wondering what's salvagable out of there. i dont know much about it, so any motors or fun stuff in there? ;)

Yep I had one like that,it was yellow and had the fake wood on top :)

Is the condenser warm?Mine was passively cooled,does yours have a fan,and is it still working?
You can rig up a heat exchanger and use it as a water chiller fairly easily.

If I were you I would sell that thing on ebay to some guy who can build a kickass waterchiller out of it... With the money you can buy parts for a normal watercooling :)

Or not :confused:

You can make a nice waterchiller out of it very easily,just have to make a heat exchanger.

I wouldn't trust that thing with my pc if the performance has decreased... I think there is a leak in the system, killing the performance. You would have to search the leak, fix it, test the system and refill it. Basically the hardest part of building a phase change cooling.

Pretty easy to do....
But we still dont know if the freezer had a fan cooling the condenser,it may have crapped out..
Possible high ambient temps effecting it.
What kind of temps did it get before?
Does it run nonstop?

Man, lets think about this!

PUT THE RADIATOR IN THERE!

If you chill your rad (it's the part giving off all the heat) then it can transfer more heat because there'll be a greater change in temperature and ultimately allow you to have even greater cool abilities.

Just fix your freezer up a lil, put the ice cream and all the goodies right back in next to the radiator. Not sure if the radiator will heat up your ice box significantly to warm those frozen products up, but I'm guessing it shouldn't.

[aenigma]

Nope that wont work.You would think just putting a rad in there would cool good,but it doesnt.
You have to design a heat exchanger for it.

[cheez]

Your gonna hafta explain why it won't work better.

It should work because you have a liquid warm liquid flowing through a cold radiator. A high delta T would thus lead us to believe that it would increase the amount of heat we are able to expell from the system.

Q=m*c*deltaT

m - mass flow rate
c - specific heat of water
Q - change in heat
deltaT - change in temperature

Keep m and c constant increasing our deltaT would thus increase the amount of heat that is exchanged.

Incase I'm missing something here.... it should work.

I have done it before,I guess that would be a good way of explaining it :rolleyes:
Not enough surface area on the evap to cool the air.
