Homebuilt Refrigerator

[calbiterol]

I've searched the forums.

I've searched online.

I've searched high and low.

I understand the principle behind them (for the most part - but any in-depth explanations would be cool.)

 

But I can't find what I want.

 

 

So, HOW can I make a refrigerator from parts readily available (like, go to hardware store, etc) that is reasonably safe and (probly) legal?

 

P.S.: I did find one design, but it didn't really show me what I wanted.

Why dont you look at homebuilt computer cooling sytems you may find something useful.

buy some meths to use as a coolantand lots of pipes.

[calbiterol]

Meths? As in, methanol, etc?

While I'm at it, can a stirling cycle engine (in reverse, or something like that) be used to refrigerate?

if you had an air compressor, you could make a vortex freezer?

You cannot beat a sink full of cold water in the short term(from student days living in digs). Works great for milk,not so well for sandwiches,though i may have wrapped them up wrong!

LOL, I rem doing similar to that with Beer, we had an old record player, so we arranged the beers on the turntable put a wet cloth over it and pressed Play

and so on...

 

they can also be used to Heat things (the "waste product").

How many of these could be used (hypothetically ) to refrigerate to liquid-nitrogen temperatures?

easy man, go buy an entire ac unit from an old car in the junk yard

 

Get a air tight box.

 

Setup the Auto AC to blow cold air in the box

 

Use an electric motor and a pulley and a belt to drive the ac pump.

 

You could use a lawn mower engine, but, wouldn't be a very cost effective.

 

I have no idea how cold you could get with this, maybe you could use multiple systems, or, if the area is small enough it might get pretty cold.
