Mini Fridge Mod Anyone?

but hotter, as the heat from the compressor dump will be added and added and added.

The room will get colder due to the latent heat needed to thaw the ice/stuff in the fridge. For every gram of ice, you need 2 joules of energy to raise it's temp by 1 kelvin, whereas you need to lose 1 joule of energy to lower the air temp by 1 kelvin (and that's ignoring the latent heat from the ice).

If you had a freezer that is vanilla, ie no ice etc in it, and it's at room temp when you turn it on and open the door, if you stick with the conservation of energy, the room shouldn't get hotter or colder (but that is ignoring heat from the workings of the pump, but that would probably be negligible, but would depend on the size of the room).

You'd be incredibly suprised how much heat a compressor dumps into the room Phnom. As a phaser I know 200+watts is very easy with a single stage size compressor.

The ice won't form with the dorm open, and if its already there, when it melts off your rooms going to heat up. Go try it, open your fridge and freezer.

Do you mean the heat it's pulling out of the freezer, or the heat it's generating from working?

But the melting cools the room down .

I don't know why people are arguing this. The fridge cooling concept will not work, and I don't mean 'will not work in theory', I mean it has been tried, over and over and has failed miserably. All the fridge is good for is greating a sealed container.

Secondly NoL is right, the room would eventually get warmer. A fridge works by removing warm air from the closed container and pumping it out the back, in the process making it nice and warm. If the fridge door is opened, the temperature in the fridge will equalise with that in the room (reducing the temperature very slightly), this air will then just go through a heating cycle in the fridges pump system, raising the temperature of the room. The same goes for a freezer phnom, just reaching an even temperature in the room would take longer.

The heat its generating from working. The heat thats pulled out of the sealed box, when its open, is pushed right back into the room and thus the box.

The melting won't last you forever.

@llwyd, no I'm not saying the fridge idea works.

I presume the heat is generated by the pump etc, because the energy being taken out of the room should = that being dumped - the heat from the working of the pump

I didn't say you did mate, I said that the ice in the freezer wouldnt make much difference other than to prolong the warming

 

[NoL]

Yes the compressor will easily heat up the room.

Erm wtf.

 

[NoL]

He's talking about making the room nice and warm.

How many fridge's do you have that work like that?

 

[NoL]

All of them. Thats how they work. Thats how refrigeration works. Thats how phase units work.

I'd go more along the lines that you have a gas like freon, which you compress, causing heat to be released, and then you use the heat from the air in the fridge to expand the gas. Which then removes the heat energy from the fridge to the gas, and the gas is then compress again removing the energy from the gas to the outside world.

Yes, once the gas is expanded it is now warm, then it goes through the compressor and gets hot, that heat is then dissapated into the room.

gdgd, I was a little worried by what you said earlier

For a more intricate explanation check the Phase section sticky's that Ive written

 

[setite]

It looks like everyone pretty much has this one covered, all that's left to say is: Hi Setite, good to see you again

thanks... the forum finally peaked my interest again... fragtek knows why

Aye nie to see ya again Setite

thank you too

what about trying a freezer not a fridge , putting the rad in the freezer?

Well thats why I like the mini-fridge idea. Mine freezes stuff so its more of a crappy freezer than a fridge. I see no reason why this wont work... I planned to stick the radiators in the fridge. I presume that the reason this hasn't/doesn't work is because the radiator is truly effective and removes more heat than I know about and would heat the fridge space very quickly. Thus creating a hot room and heating the ambient. I don't understand why the fridge compressor would break, I would assume it would just continue trying to work but failing. I presume that the fridges that break are ones that monitor temperature and work around the clock to failure. I would love to do this and prove you guys wrong. But I have shelved the idea for now. After realizing that the full potential of these processors can be reached on air I realize that I may never watercool at all. If I do, I figure slapping a waterchiller on would serve my purposes better. Although I can't find them in the US.. not like the ones I've seen on the forum that lend themselves so well watercooling. I do appreciate the welcome and I apologize for leaving this thread be without replies.
