If anyone is wondering, this is how they make heating and cooling seats in cars. You don't even need to turn the peltiers over. You just switch the polarity. He may have made an AC for the summer. But he also just made a heater for the winter.

As an Engineer to a colleague - I just love how you placed your power source cables right on top of a 70 c heat exhaust. Now, that is just a beginning of an ocean of problems for this - wrong - toxic (nitrates producing) potentially explosive assembly.

You went to all that trouble to produce this, and the whole point was to show the cooling effect, but never put a thermometer in front to show how it cooled. Why?

i was waiting for temp. test at the end

It would be nice if you showed us the ambient temperature as well as the output temperature. We would also like to know the total energy consumption. Hard to know why you overlooked those critical items.

Unless your going to be hanging the back outside a window your making more heat on one side then producing cold. Plus the electric for these are high.

[cryptonoob]

why bother to make this if you dont show us the output of the box. Temps power used etc.

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....
PS: i made a refrigerator..not an Air Con..cause there would be a lot of work for an isolated air con.

I love how the heat from the peltier just warms up the room more then it can get cooled down

[alexcordero]

An amazing concept, however, unfortunately the most inefficient air conditioner in the world lol

Nice Room heater. Great for cold Days in Winter.

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

[pengiethebird]

Without the hot side being exhausted to outside you will actually heat the room. What happens to all the condensate from the cold side? You need a drain pan. Back to the drawing board.

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.

One of the better ones that I've seen made in youtube.
It's always good to have the correct tools. Makes projects a lot easier and cleaner!

Eficiencia muito baixa para o uso "domestico:...
peltier = 400w, (100 btus + -) 24h/D = 9.6kw
A/C = 7500 btus 900w 10h/D = 9 kw
75 vezes menos eficiente, ou seja: "custa" 75 vezes mais em energia.
Mas achei interessante o processo de montagem! Deu pra aprender algumas "tecnicas". Obrigado por compartilhar conosco!

🐸 very disappointing vid! Not even one temperature mesurement at the of the vid 🤣very well made box for birds though✔️

[alexandrejose]

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

[CTRLALTGeek]

I recommend putting the AC at a window to create temperature differences. Overall, nice work!

[NaimRack]

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