moonlit Posted July 17, 2006 Share Posted July 17, 2006 Some of you may have noticed that the temperature of some parts of the world is getting rather high now, so I wondered if any of you have rigged up any ghetto cooling devices for your desk/room/office... Here's mine (soon to be rearranged, I think): Powered by a variable 12v/600mA wall adaptor. Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 17, 2006 Share Posted July 17, 2006 Since I have had nothing to do for weeks (and I still have weeks of nothing to do), tomorow (today, what ever) I intend to make a exause for my room which will be room fan powered and use black bin bags (that will probably melt) as a method of controling the air flow.

moonlit Posted July 17, 2006 Author Share Posted July 17, 2006 haha! sounds awesome, do post pics when you're done :D Quote Link to comment Share on other sites More sharing options...
melodic Posted July 18, 2006 Share Posted July 18, 2006 my method is swinging my door open n closed really fast :D Quote Link to comment Share on other sites More sharing options...
moonlit Posted July 18, 2006 Author Share Posted July 18, 2006 But that kinda makes you hotter, 'cos you use loads of energy swinging the door :/ Quote Link to comment Share on other sites More sharing options...
kainchick Posted July 18, 2006 Share Posted July 18, 2006 lol i have a little cheapy ac, that get's a little bit colder than a fan blowing directly on you. Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 18, 2006 Share Posted July 18, 2006 I have my black bin bag based exaust system fully workingness! It's not as effective as hoped, but it is better then it used to be, and will keep out the bastard instects, i'll take some pictures and post them.

Sparda Posted July 18, 2006 Share Posted July 18, 2006 The pictures are here That computer is not my main desktop! I need to practice taking pictures. My camera sucks! The slightly blurry fan with the *cough* tubing atached! Quote Link to comment Share on other sites More sharing options...
stingwray Posted July 18, 2006 Share Posted July 18, 2006 I don't quite get what you are trying to accomplish Sparda. It looks like the fan is just blowing the air in your room out through a bin liner. Is it me or do fans work best when they are blowing towards you?

Sparda Posted July 18, 2006 Share Posted July 18, 2006 The fan is sucking air out of the room thus lowering the air presure in the room. The lower air presure in the room then sucks air from else where, namly down stairs, which is very cool, the air down stairs is cool that is. It also keeps out flying insects.

metatron Posted July 18, 2006 Share Posted July 18, 2006 The heat doesn’t bother me and any equipment important to me is in a air-conditioned room. Quote Link to comment Share on other sites More sharing options...
stingwray Posted July 18, 2006 Share Posted July 18, 2006 Perhaps we could have some temperature readings when it has been off for 15mins compared to when it has been on for 15mins? Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 18, 2006 Share Posted July 18, 2006 I don't have a termomiter :( Quote Link to comment Share on other sites More sharing options...
melodic Posted July 18, 2006 Share Posted July 18, 2006 i can see your reason, but doesnt look like it would make much of a differnce apart cut you off from fresh air Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 18, 2006 Share Posted July 18, 2006 No, the windows down stairs are open, fresh air by proxy, any way, air from out side isn;t that fresh any way. Lots of car exsausts. Quote Link to comment Share on other sites More sharing options...
melodic Posted July 18, 2006 Share Posted July 18, 2006 so your sucking in exhaust fumes into your room? Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 18, 2006 Share Posted July 18, 2006 Hopfully not, hopfully the exaust fums are too heavy to be pulled up. Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 18, 2006 Share Posted July 18, 2006 Talking to Horza (who hasn't been here in a while) about heat discharging, I came up with a stupidly brilient idea. Nearly every modern house in England and america is equiped with central heating (that is, pumping heated water thogh out the house in to big metal heat sinks which heat the air). Well, why can't you use the same system to remove heat from the air? Of course they would not work at full efficency mounted near the ground, but so what? It's better then nothing! Any way, this is another idea of mine thats fairly barking mad. The way I see it is you could just pump the same water that is used to heat the house in summer but make it cold. The problem I see with this is that if you have plastic pipes they might ruptur if you have the water too cold. Other wise it should work! Another problem is heat distrabution, obviusly the heat absorbed out of the house has to go some where. So now you have a big heat sink atached to the back of your house (or garage) whcih gets hotter then a big peive of metal in summer shoudld, you probably want a fan blowing over that as well. Any one see any problems with this? Quote Link to comment Share on other sites More sharing options...
VaKo Posted July 18, 2006 Share Posted July 18, 2006 Could you not just hook in a series of electronic coolers in-line with the output from the boiler, then run the heating with the boiler swtiched off, but the pump working? Just turn off the gas to the heating and run it normally? Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 18, 2006 Share Posted July 18, 2006 That method works as well, but that leaves open the posability that the very cold water (cold but not frozen water = 4 degrees C) could damage the inside of the boiler. It depends on what the boilers internals do and what they are made of. Normal copper piping should beable to widthstand 4 deg C water, not ure about the internals of a boiler. On another note, my system seems to be working, only had two flying insects so far, and tehy where probably in here since the preiviuse night.

VaKo Posted July 18, 2006 Share Posted July 18, 2006 Not sure that it would, you might get condensation on or near the boiler electrics... and on all the radiators in the house. Quote Link to comment Share on other sites More sharing options...
Sparda Posted July 18, 2006 Share Posted July 18, 2006 I found a problem wih my madness! Condensation, cold metal in a room full of warm moist air = condensation on the metal. Other then dehyumidifiyers I see no way around this. There is no way that I can see that will prevent condensation. However, the best solution I think would be to desighn the radiators so that any condensation that does form is gathered in a sort of drip try underneither the radiator, whcih then disposes of it down a waste pipe. I also propose that radiators stop been desighned for been installed horazontily, and that they be vertical. There by giving them optimal performance for both heating and cooling a room. Ye, I'm a crack pot inventor. Quote Link to comment Share on other sites More sharing options...

Sparda Posted July 18, 2006 Share Posted July 18, 2006 It's a concept of cooling the whole house using the exsisting piping that is used to heat the house in winter melodic, you should realy pay more atention in school! Quote Link to comment Share on other sites More sharing options...
