Need help w an engineering class project...
Hey guys,
first post :) Anyway, I have a new venture creation/engineering class and they require us to write a business plan based off a product we create. The long and skinny of it is that one product I wished to create was a low cost fridge for home consumers (24 cubic feet) for under 300 dollars. I was thinking of using thermoelectric modules in lieu of compressors. Can this even be done? What would you guys do? ANY input would be great! I need helP!!! :)
- A very grateful student!

Hey,of course you can make it,but exstremely exspensive solution,
thermoelectric works guite fine with 1 module down to 2 degrees centigrade,
if you try 2-stage or 3-stage system you can easily get down to -30 centgr.
but the effience seems to be very low compared to other systems ,lets
say it in this way:you have 1,5 more input power than cooling capasity.
For higher power effiency yo`ll have to build a large switch-mode power
supply,typical for 1 module is 4 volts/3.5A=about 12w cooling capasity.
ex,for high temp use like aircondition it could be used,but as I said compared
to R410,Co2 it is a extreme ex*****ive ineffective solution yet,bit with
new materials in the module maybe
have nice day
