Unfortunately no. If you understood basic thermodynamics you would know that this type of setup (in this configuration at least) cant do anything apart from increase your energy bill. The reason this doesn’t work comes in with the way the heat exchange is set up. As we know, Peltier modules or Thermo electric devices, produce a cooling and heating effect on both sides. Which side gets hot and which side gets cool depends on the direction of the current AKA electron flow. Taking this into consideration, the whole reason AC works is because of the way temperature works. Temperature in itself is defined by the average of kinetic energies across all particles in a given amount of matter. So when we cool a room using AC what we are really doing is removing that kinetic energy from the matter present in the room (i.e. molecules in the air) and 'placing' it elsewhere, we do this using methods of thermal exchange. In this case heatsinks and rotating fans. So for AC (in simple terms) we need two main things. Something that provides a thermal flux, that is a flow in thermal energy. AND something to make the heat exchanges efficient so that we may move this heat elsewhere i.e. OUTSIDE of the room we are trying to cool. With a system like this, our component producing the thermal 'flux' is the Peltier module but in a more common device might be a compressor system. In a compressor system we use a closed loop refrigeration system (this is important) and we alter the pressure that a refrigerant is under. Because of the way the ideal gas law works, when we keep volume fixed (closed system), and pressure is increased (with a compressor for example) temperature must also increase in a fashion that is proportional to the increase in pressure. So, by lowering the pressure in one side of a closed loop, temp of the refrigerant drops and therefore absorbs heat from the surrounding air (via heat exchange methods - heatsinks and fans) and increasing the pressure on the other side, there will be a natural thermal flux between the two sides. The hot side of the AC will warm up as the cool side cools the room, as you may know energy can not be destroyed or created, it can only be moved and change in physical form. Due to this law your set up will not work in this layout. While you don’t use a compressor in your build the same logic applies. Our intention is to move the heat or kinetic energy out of the room but with your design the heat has nowhere to go. On both sides of your Peltier modules you have fans and heatsinks this is correct, but to truly cool the room we must move the heat elsewhere i.e. outdoors so it is not radiated back into the room (which is what happens with your setup). Now, another thing to consider is that no device in this world is 100% efficient so your Peltier modules may be 90% efficient at best and also resistance in wires results in further heat radiation. This means you aren’t even breaking even on your heating vs cooling power. This means as a NET total you will actually heat the room up as you are feeding electricity into a system with nowhere for the heat to go apart from back into the room you are trying to cool. ps. Ideal gas law: Pressure and volume of a given mass of gas at a constant temperature can be given by: P 1 × V 1 = P 2 × V 2 AND If you want to make this design in a way that actually cools the room then simply add a heat removal system. Basically the heatsink for the hot side should have a coolant flowing over it and then the now heated coolant should run to a radiator (with fans for higher efficiency) to a place you don’t mind heating up. This could be another room indoors but any sane person would put this outdoors, it just makes sense. I think a more accessible way to do this would to be to use a AIO liquid cpu cooler. By simply cutting the tubes that run from the radiator to the cpu block and adding a few more meters of tubing (and topping up the coolant after resealing the tubes) this i think would work pretty well as a heat exchange method. Another thing to note is that for this to be truly efficient, you should be using much finer heatsinks. Basically you want as much surface area to volume ratio to maximise heat transfer from the air to the cold side of the Peltier. I mean you could also probably use a cpu AIO cooler for this aswell. pps. Hope this makes sense! Don’t be fooled by these awfully seductive physics scams!

[@user-pg1lg1bt3u]

So basically, what you're saying is that the side that is heating up the room should be placed outside a window or something so that it actually helps the cool air flow a bit.

[@biscuit5061]

The heat from the heatsink isn't like the refrigerant that can flow easily in pipes, so I'm thinking maybe make the heatsink hot side contact with a circulating water source, which then the water goes through a few lengths inside a copper pipe with a fan blowing to reduce the water temperature, water is good at transferring heat. That will help keep the hot side under a manageable temperature.

[@paulocavalcante5795]

Verdade.

[@mametzop7586]

Creative, you can use the hot side to make a water heater.. using a peltier water block and a circulation pump. use enough water reservoir to retain heat. that way the hot side doesn't affect the room...

[@anshadmulavoor5630]

Wt about hot air.. it will also flow in the same room ..right,?

[@belajarilmu2009]

Bagian buangan hawa panasnya harus diarahkan lagi ke luar ruangan brow, ke bagian luar tembok dan disedot atau dibuang lagi dengan kipas yang lebih besar. Kalo nggak, hawa panasnya juga menyebar ke dalam.

[@user-si5eg6xg3q]

It was a creative idea But I wish you could cover the blower fan like a box to prevent the wind pressure of the blower fans from being wasted around and experience more wind pressure.

Marvellous job,i admire you WEMYOUR👋

[@WEMYOUR]

Thank You, Dear

[@3nginuur]

This does not work. It produces more heat than cooling. Temp shows cooling at the heatsink, the air blowing through it will still be ambient. Peltier units are only efficient in small foam enclosed boxes for cooling.

[@patchalaseshamma9262]

Once check the placement of peltiears

[@Yner56]

This means that your room is hot or wherever you put the fan of the AC is hot. You need to put the fan in a colder area.😊

[@JhonardMiranda-vd4zz]

Heatsink and fan is produce heat instead of cold air because its warm in long time of using

[@alexdmon4778]

Why is the cell on the cold side small? They cannot both be equally large so that by being able to reverse the polarity of the Peltier cell Can it heat and cool?

The self-made cooler produces both hot and cold winds. What a stupid way to do it. It wastes only electricity and does not offset each temperature, so the average temperature goes higher.

See what are you doing? Ans:- you are cooling and heating the desk, so do you think their will a temperature drop? Working of refrigerator cool from inside, hot outside. If I do both cool and heat inside it will neutralize the temperature. +++++++++++++++++++++++++++++ This model will precisely work perfect but need slight modification. ++++++++++++++++++++++++++++++ You may ask what modification? If you really want to make it cool then use water/bike coolant to treat heat. Use:- Small bucket with top lead covered. Fill the bucket with water or coolant. Buy Alumunium heat block big sized. Drill two holes on top of bucket lead to pass water pipes and use epoxy to secure the pipes or any leakage. Use 12v DC pump(not submersible) to pull out the water and send the coolant to alumunium block for greater heat exchange the pump should cycle this process. If the lead of bucket is covered then the hot water will not vapour which will indeed keep the room cold. If the hot water vapour come out of the bucket same problem you will face neutral temperature. ************************************* Don't secure the lead of the bucket permanently with epoxy or any sealant you may need to change the water when it get extreme hot. For water it may be necessary to change after 4-5 day use for coolant not necessary. +++++++++++++++++++++++++++++++ Try out this will work perfectly no outdoor unit required. After doing make a video. I am sure this will work as charm if all is perfectly assembled. Hot side instead of big heat sink, use alumunium block and don't joint cold and hot side with metals as will reduce efficiency use zip ties.
