i made a similar project few months before....in my design i just used two peltiers (consumes only 5A each)...in order to increase efficiency you need to pulse the input current...by using an IGBT or a MOSFET. the peltiers can handle 2x more power when its input supply is pulsed at high frequncy, and also removing much heat from the hot side can improve its performance...say pressured gas loop....

He had two options, or put the fans directly on the heatsink, so that the fans could only grab air from the heatsink, or the second option was to put a cap around the heatsink to force the air to go through the heatsink first before pass to the fans. It is also very inefficient, you cannot cool a room with it, although you could make a smaller version with one or two peltiers to keep temperatures inside a computer case low if you have a very high ambient temperature. or even on an electric control board

The idea is nice. Would maybe use heatsinks like the cold-side one for both sides and then have the fans blow in one direction over it making it possible to exhaust the hot air out of the room.

Nice build, there are a number of reasons why this won’t be effective though. Peltiers are 2% efficient, that’s the first. Not having said that it was for a particular size area or any specific application it would have been good to see the temp of the cold air expelled. I’d like to see this principle, or indeed this particular model adapted to a cooler box. The heat pump effect would not be an issue. Having said that it would be too “power hungry” for a mobile application. So I guess “Home made Beer Fridge” might be the go. The other interesting point with peltiers is that they can keep a small area or amount of medium very cold but apparently cannot get the initial temperature drop to their efficient operating temperature with larger areas. Cooling a circulating fluid was mentioned in a few of the comments , now that MAY have potential. Just Saying

There are many 110 volt units but very few 12 volt that I could find. There are 12 volt Marine units with water cooled condensers but not 5k to 10k btu units that use air to cool condenser. With 12 volt you don’t have the losses of the inverter. Clearly you know your electrical engineering!

good idea ....... for air conditioning.but peltier suits to refrigeration of both hot food items and cold food items as we fix peltier modules with an insulating material at centre..chilled side is used for cold food like ice creams and drinks.,,,and hot side is used for bakery items like puffs,rolls,etc....so that its heat is also be utilised with mini refrigeration

It's an interesting idea, especially as a diy teaching tool.not sure what use it could be considered efficient in; since I am not well versed in the "Peltier Thermoelectric Effect". It is interesting.

Right

What you really should do with this is submerse the heat(cold) sink in water. Water can freeze around the fins offering longer cooling. You can even shut the peltiers off after a certain amount of time to save on electricity. These put off alot of heat it's a good idea to figure out a way to vent the heat to the outside just like a traditional ac. Or just put a few up into your ceiling and vent the heat into the attic.

Also add some details of products, After u have done the project, show us output like temp, electric used etc.

Pleas make good incubator 🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒❤❤❤❤❤❤❤❤❤❤ tanks man

Needs a secondary switch to turn on the cold side fans since you may want cold air blowing, not room temp air. Needs an exhaust vent to a window at a minimum. However, if you stored heat in water and could sewer the water so the heat is lost, that would be more effective standing alone. Very expensive cooling with required upgrades, only adds heat to a room without the fixes.

I like it... good demonstration of the principle.

use tubing to dispatch cold air, this device should be hanging outside (nice idea) dry but kinda cool

I think you should have placed a thermometer nearby to measure the temperature generated by the box.

1- the fans on the front are not close enough to the cold sink, causing a not very optimal air flow. 2- The cold sink side is probably going to build up condensation. 3- Hot air in the back will just go around to the cold side, and leave the room hotter than it was before. Peltier elements (same system like this), generate heat, they do not cool. 4- Might work ok as a dehumidifier, or a space cooler, but that's it.

Correct. The fans need to be virtually in contact with the heatsink fins (CPU coolers are OK,) to force as much air as possible thru the fins, and in contact with the grill so there's no recirculation of air for either heating or cooling spaces. Also, bolts etc passing from the hot space to the cold should ideally have thermal insulating washers between them and at least one of the heatsinks (a washer with a hollow collar, like transistors use) or should be non-metallic bolts. This especially applies to the 2 bolts fixing the heatsinks to each other! They are a direct thermally conductive path from the hottest point of the hot side to the coldest point on the cold side, and form a perfect heat shunt in this design!

Using several of these units, say in the roof, and directing the flow through the roof, while breeze refrigerates the hot side, could become very efficient if solar power is used. After all, you need the air conditioning mostly when sun is hitting hard, isn´t it?

With this, you might be able to cool a small closet if it were heavily insulated.

Congratulations! Your system is less than 1/3rd the efficiency of a compressor/condenser evaporative system...

This is a neat idea although it would never be super efficient or a high output cooling device but it's definitely a fun project, some ideas that would improve the design would be: first you need to vent the hot side out of the room for two reason one is you don't want that heat circulating back into the room but mostly because as that heat circulates it continues to heat those peltier chips and that lowers the cooling efficiency, remember as the hot side heats you lose cooling so circulation away from this side is key. Now another design flaw I seen is on the cooling side, you should of directed the flow of air pass the the heat sink along the aluminum fins. Put the intake on one side and the exhaust on the other and drop the top lower so it is close to the fins and forcing the air to run through the fins and not around it then the air will cool before it exits the exhaust vent. These are just a couple thought for what it's worth. This is a neat project and looks like fun thank you for sharing.

back fans should be duct to outside, front fans should be on the side with the holes on the opposite side that way you draw the air threw the fins. front fans should be on a thermostat, that way they can kick one and off for optimal temp. also insulate the box completely for the cold side. it will cool well and be more efficient. it still wont be efficient but more efficient.

This isn't going to work unless you radiate the heat outside.I built the same but the modification I made was that I attached a watercooled heatsink on the hot side and attached another water cooled heatsink outside the room with a large fan and interconnected both the heatsinks to radiate heat outside of the room. I also attached a water pump to regulate the water in the pipes. Worked very well. It can't really replace a real air conditioner but it's a fun project. I'm also thinking of using an arduino to make a bluetooth remote for it to monitor temperature on my phone and alter the fan speed. But again it's just a fun project and can't really replace a real air conditioner.

Heat and cold will cancel out, ends up with power supply heat up the room.

As good as it might look, peltiers are highly inefficient. They have an efficiency of 10-15% of ideal carnot cycle which if not done properly can drop to 2%, while conventional VCR cooling system have an efficiency of 40-60%. Which mean if you supply 240 watts of electricity, assuming efficiency = 10%, just 24 watts are getting used for cooling, while rest is wasted as heat. And don't even think of using it in a closed room, unless you mount it on a window with hot side out.

Coloque as duplas em formato sanduíche e conecte-as em série. Terá quase metade do consumo e muito mais eficiência. Nesta configuração algo em torno de 2 graus. Pode chegar a até 3 em formato sanduíche, chegando em torno de -10º

You should make water cooling for the hot side of the video, cause it also affect the temperature of the peltier in the cool side, i like your vid, keep it up

Can you please provide the parts list or Amazon India urls to buy them. Excellent video.

peltier = 400w, (100 btus + -) 24h/D = 9.6kw air conditioner 7500 btus 900w 10h/D = 9 kw

Why is that inefficient? In 10hrs per day of using AC you would consume 9kW while in 10hrs of using this diy peltier AC you could only consume 4kW..

cooling capacity is low compare to ac

10h of peltier cools way less than 10h of AC, look at the btus

I saw alot of people comment on the inefficient design of this and I have two questions. One...if you wanted to put this unit somewhere other than a window and set up some sort of hose to a window as exhaust, that would help right? Two, what else would make this design more efficient? More peltier coolers? A bigger heatsink? I can see someone wanting to do this as a upgrade to just having a fan without getting a full size window a/c unit. Are there better designs out there you would recommend?

i think that with more peltiers this will be less efficient. if i have to do it, i will use only 2 cells TEC1-12706 (60w), regular pc coolers for the cold side, and one more powerfull for the hot side.

That's an awesome video really, but i saw you should use Coolers in both sides because the cool expand better with one cooler, but is great the design and construction please tell me what material aré you using because i dont know what's that, looks resistent but almost you can cut It with a cutter, i want to know to use It too please

hot and cool...If you don't remove the heat, it's not much use. Good job.

you make this on my request thanx dear i will try this

nice / but you should fix a tempreature display also

No temperature for the air stream? It would be more efficient to make a sealed tunnel, funneling the air into the cold fins of the sinks before blowing out. Rather than having a big box with a lot of air can move without the need of going through the cold fins of the sinks.

This is actually an electric heater....

That would depend upon the polarity of the TEC's.

Looks interesting but that’s it. This thing is completely useless because it’ll output more heat in the same room instead of cooling it down. Because the one side of the Peltier gets cold an the other gets hot. And as the other side gets hotter the cold side will begin to heat up as well. Plus the hot air from the hot side is being blown into the same room you’re trying to cool down. It just doesn’t make sense.

archer anthony canete great then I need to make a 1.40x1.40 Meter (55x55 inch) big Peltier Module... that wastes so much power.

If you don't know what is is doing I doubt adding voice or giving you temp readings will help u much but a better question is how he plans on handling the condensate. Better add a pan and drain line in the Norton of the cool side and some insulation between the two hot/cold sides.

i like it, you did a very nice job
