TEC - Peltier Effect

Hello,

Since the late 1800's the "Peltier" Thermoelectric theory has been evolving. Since the 1960's nothing has really changed on for the P-type and N-type semiconductor in a TEC module... all the modules you see online and for sale at eBay are the same as it was in the 60's. Still the same inefficient modules.

I think it is time I find a factory and engineer that can assist me in this journey of mine for a better efficiency !

Working with some old friends that are engineers at FoxConn (they are the factory that builds Apple, Sony, and Motorola here in China). We have a few changes in store...

I am continually told... it is more easy to take an inverter and connect to the batteries, and then to an AC powered compressed Freon gas window unit to cool any room, and they are more efficient any way... No One seems to remember that Freon gas is part of the CFC problem that keeps enlarging the hole in the Ozone layer... I am looking for a solution without Freon gas, and will be just as efficient or more efficient...

Here is the Plan...

Here is a few of my assembled (at another factory) units with different P-type and N-type semiconductors we are experimenting with...











I currently have the small unit in the V-Birth (25 square meters (267 square feet)) running 24 hours a day keeping the area at a comfortable 70F (22C) at 47% humidity, and it now consumes only 5.3 amps per hour, and with the "snap switch" (thermally controlled switch) installed, will actually shut off in the evenings for several hours when there is no direct sunshine on the boat. I am adding up 4 weeks of use where daytime temps are between 93F (33C) to 98F (37C) with a humidity of 72%, and the evening temps are between 85F (29C) to 90F (33C).

I am doing real world test, and not some formula on paper to get my results.

Truly inspirational

Love the Peltier concept and the batteries are great idea…. Hope I can come along for the ride…

I have a 49 cu meter room I would love to cool… my home office…

27C and 30% RH… so a little different from HK.

Hi Dan,

I had to re-design the Peltier module semiconductor for my use. The current TEC module is about 16% efficient, and after 18 months working with several factories we are above 80% efficient. So we are golden in my world... HaHaHa

Hi Alan

Very impressive....80% plus. Keep up the good work....

Dan

When are you going to let the rest of us get hold of your improved TEC modules ?
I have 2 cooling projects I'd love to try out with them.

(oh neither to do with boats, so you're safe there)

I bought one from eBay....attached a couple of batteries....28c when I started. Pointed the hot bit out the window, put a thermometer in front of the old bit....45min later 28c....

Hope Alan's is better than the one I bought....

Still love the concept....

Dan

I like this concept as well and looking forward to it's availability. Off-grid heat and cooking I can do with a wood stove, but the only off-grid way to be cool that I know of would be to live in a hole.

Any updates? on one that works.

Hello,

This seems to be a very popular device that interests many... I will need to get them installed on the teak boat soon, so I can make a few video's showing others how to make them as well !

Alan

Wow any update on this?? I will really like to get many of these if available.
Do you plan to do a kickstarter or have a online shop?

Great job

Cheer

Alan, please give us some news regarding this...I would like to buy some of your improved modules.

Keep up the good work btw
