Thermoelectric peltier Air conditioner project phase 4

[chethan730]

can any1 tell me how to do a car ac we r doing it as ur project our sir told tat we have 2 do it using vapoua absorption refrigeration system he is telling tat we shld design the generator of the ac so tat we can recycle the exhaust gases nd take the exhaust gas as an input 2 the car ac..can any1 give us an idea..?

[KeithWasHere1]

hes telling you re introduce the exhaust gas back into the cabin??? is he planning on killing the occupants of the vehicle?

[cayuga420]

@KeithWasHere1 he said recycle not pump it in the vehicle.

We made one, search for mes 1500 mes 2500 or mes 3500. Or email me @ vts@me.com

hey bro. you got an idea but you doing it wrong you dont need water at all you gain too much energy in the process ,and you should have enough power with 20 plus amperes if you weren't using the water pumps either ,i'm building one heat pump/ A/C for my dog's house i'm more than half ways there but i don't know if i'm gonna post a video though , good idea you just making it too complicated

@KennyMckormickk Reason i used water, is i built several others with just heatsinks.

The problem is, with heatsinks, they have to be VERY MASSIVE or they cant handle the heat load that the peltiers dump onto them without causing destruction of the peltier. been there, done that. I even used a huge 20 pound heatsink, arctic silver, and forced air cooling. no go.

The water cooling method worked AWSOME on the hot side of things. just not cold side. need heatsink for cold side.

I totally scrapped the project. Well, i told the guy that machined the water blocks and the distribution blocks with mounting plates for me, he made the distros out of steel. i told him aluminum. Well, guess what, steel rusts. it rusted as it sat, and clogged everything up. its all done. Hey, it was worth a good go anyway.... now its all scrap metal

@THEtechknight

I am interested to purchase the waterblock system you have.

[richcsst]

@THEtechknight You should have had a 50/50 mix of water and radiator fluid. This would have avoided the rust. Any car or computer geek would tell you to never use 100% water as all metals corrode, just in different ways. Polyethylene Glycol is an excellent corrosion inhibitor.

if you stack the peltier, yesh you will get greater temperature, but the liquid requires time to heat up or cool down.. biigger surface area..

[zr2ee]

definately agree with this, water cooling for the hot side is a good idea but for the cold side would take forever

[g60scuzz]

I was thinking about this and then found this video. I had a couple of ideas to throw out there.. 1st suggestion would be to stack them say 6 pelts and 3 sets of water block or 6 pelts and 2 sets of water blocks. For a greater temperature extreme on the hot and cold sides. Your water setup can carry much more heat.

been following these with much interest. In this vid we are starting to get a desc. of the parts in the system. A 'phase 0' video showing what all the components are would help. Is there a peltier under each thermal block? How did you mount them? what wattage? how much power supplied to it? How did you make the thermal blocks? what kind of pumps? Curious if you ran the system on one car battery how long it would go and how much sustained cooling you could get on one battery charge.

[THEtechknight]

maybe if the heatsink was made out of pure copper. but the efficiancies were terrible, alot worse than this, thats what made me move to this type of setup.

I'm needing to do basically what you are doing for a trip to the desert. I was wondering if you had tried cooling the air directly with a Peltier cooler so that there will be less loss from trying to cool water that cools air? My needs dictate that the system is portable to the desert in my already densely packed vehicle. The cooling required is for a a small Yurt. Thanks.

[THEtechknight]

good luck with that. hehe. im unemployed, just made this stuff with parts laying around.

[nelbmahs]

Good Job! Now all you need is to solar power it.
