Your dad sounds cool. ;)

haha, yes! that's awesome

My dad would have loved this channel. I do too.

He is dead now, r.i.p

Thanks!

And, thank you for the compliment!

I would still say The King of Random was fun to watch, although of course much less serious

Most important of all, he showed those graphs. I needed someone to explain it. It seems pretty simple now but it is nice to have someone present it. I would like to achieve really low temps with TEC. Maybe I will use CPU heatsinks with heat pipes to pump away the heat.

Oh i'd LOVE to see them collaborate once! Would be a total geek-out! Or at least the conversations between them would be more than interesting/entertaining :)

I like TECs and I like your plan, but did you originally want a low power fridge or a super small one? Just a chest freezer, with a refrigerator's thermostat swapped in, offers a lot of space and it's very energy efficient. That's the route I went years ago - chest freezer to chest fridge conversion.

Thanks!

Thank you!

I absolutely agree.

An added benefit of it is snowy outside, let us see the main use of this device in summer.

@@wobblysauce if its snowing, jist put food outside😂

-3 *c outside. So that's around 50*c difference for a stacked TEC modules

Take a look at our video on the solid state mini fridge. There I go into a pretty good review of the principle behind the operation of these devices.

@@TechIngredients Most excellent, thank you for the tip. Happily subscribing!

I am too! Welcome.

Thank you!

so which is best

Thanks!

Thanks!

Sure!

I think another way you could go about stacking TECs is to run them water cooled in series, with two separate loops. The PECs themselves are only touching two water coolingheat exchangers. The chiller water loop and cooling water loops run in a cross flow configuration to minimize delta T for each one. The chilled water return goes into TEC 1 and then TEC 2 and then TEC 3 where it becomes supply and goes to the conditioned space. The cooling water return goes into TEC 3 first and then 2 and then 1 where it becomes supply to the cooling radiator. Now each TEC is running roughly the same delta T and the same wattage just different temperatures. The only disadvantage is this requires a lot of hose and fittings.

Thanks, Mr Gates.☺

Thanks!

Thanks!

Sure, good luck!

Thanks! Subscribe, link and post comments.

The setup in the video works well, but for each type of TEC there is an optimal voltage. Use a variable voltage power supply and dial up the voltage slowly (over many minutes) untill the temperature fails to drop any further.

Correct.

BTW: Sorry for my typos, my English isn't the best

CrashPilot1000 Do you mean something like this? www.soundenergy.nl/theac-25/ Heard of them on Dutch radio.

Zuckerberg is the only synth I know of.

No problem, more incoming!

I love this idea and I think it might work. A sound wave in gases (liquids) must heat and cool certain zones (low and high pressure distributed along the length). If this is done in a cascade (next line from the top), then low and high temperatures can be achieved. That is, it is possible to make an air conditioner or heater without moving parts. You just need to move the temperature gradient from certain zones and transfer them to the next. This is difficult, since there are no devices that can be bought on aliexpress and tried this principle quickly, to make a video.

That process becomes extremely inefficient because the loss at each stage multiplies. A differential of 140 degrees is possible, but remember that the "hot" side isn't at zero degrees centigrade.

Thanks! You are right. In order to present these videos I do a fair bit of research and in doing so discover how much I really don't know about a topic.

@@TechIngredients Thanks for your reply. As a, now retired, 'generalist' engineer, mainly small scale systems and their controls, I have long held that the more I learn the more I find how much I don't know. Again my thanks, especially for this video, I have been interested in TEC's for a long time and - Suddenly - I actually understand them a bit more. Please, keep up this output - we need it! What I wouldn't give for a workshop like yours!!!

I'd love to hear how that worked out.

The condensate would be hotter than the cold water obviously...

If it’s that cold outside, I bet the humidity in that shop is extremely low ...I mean he said that cold tubing is perfectly dry. Here in South Central Texas, hell, you’d have to have a collection pan under that tube because it would drip constantly, and you wouldn’t need to atomize it, there would be enough of it that you could have a cold-water bath to run your return glycol tube through, probably even through a heat exchanger immersed in the accumulated condensation. Sometimes I wonder if the condenser core in my window unit would be better off buried in the cold mud swamp that exists under it almost year-round than it is just sitting there having 105 F. air blown through it. I think the concept of using a water evaporation based system to cool the the evaporation stage of a refrigerant based AC system needs to be looked at again. The idea of just dumping what at least starts out as cold distilled water onto the ground like a waste product just can’t be right ...we’re missing something somewhere...

Pump the atomized condensate outside, lowering the indoor humidity.

Series will allow you to reach greater differentials, but at the cost of effeciency. Parallel is the way to go as long as you're below approximately 1/2 the maximum temperature differential. At very low differentials, they're pretty effecient.

With brute force, and enough power you certainly do it. We have successfully constructed a dessicant based airconditioner that is more than 2 times as effecient as a compressor based system. That video will be posted soon.
