Water Cooler Using Thermoelectric Module (peltier device)
« on: September 25, 2008, 01:54:17 PM »
I have this project this year but unfortunately it was not that successful.  I tried to compare it with the latest water dispenser pero mas mabilis pa din ang water dispenser na gumagamit ng motor, mas mabilis nyang napapalamig ang tubig.  Electric Consumption, less ka ng 25% kung gagamit nito compared sa water dispenser.
 Ano ang makukuha natin dito?
1. Environment Friendly(by not using refrigerants)
2. Eliminates Noise and Vibrations caused by the Motor
3. Portable and consume less space.

mahal ba mga peltier module? mahal kasi sa RS. balak kong bumili nung sa CD-R King na USB Ref dahil malamang peltier din ang gamit.

Mura lang ang peltier device pre, may mabibili ka nyan sa e-gizmo.  300 ata ang isa nun kaso mababa lang ang wattage nun.. not that efficient.

ah. thanks. hindi ko naman gagamitin pa sa water cooling. experiment lang. ;D

pero later on, if ma-improve pa ang technology ng Peltier they may actually replace those electric compressors.. mas maganda talaga ang mga Peltier Device kasi walang wear and tear, although puwede siya magkaroon ng cracks because of thermal stress..
I wish for this night-time to last for a lifetime
The darkness around me
Shores of a solar sea
Oh how I wish to go down with the sun
Sleeping
Weeping
With you

I walk alone
Every step I take
I walk alone
My winter storm
Holding me awake
It’s never gone

I fear that soon you'll reveal
Your dangerous mind
As your true colours show
A dangerous sign

ah. thanks. hindi ko naman gagamitin pa sa water cooling. experiment lang. ;D

nung nagbasa ko sa book tungkol sa thermal consideration, maganda daw ang pertier plate gamitin. kaso kung iisipin, mahal pa din. kung gusto ko palamigin ang buong board, kailangan malaking peltier plate din para macover mo ang boung board. hehehe

or ilalagay sa enclosure para kahit maliit ang surface nung plate, pwede pa rin. merong application nito ginawang mini-ref 'yung maliit na cooler. pwedeng dalhin sa camping. ;D 12V battery ang source niya.

hi sir itoy..

share ko lng project ko sau dati.. e2 yun defend ko bago ako mka graduate ng electromechanical


ayon sa ganyang design hnd mo na kelangan gumamit ng motor compressor pra i compress ang refrigerant gas or freon.. kasi alam naman natin [physics] that pressure is directly proportional to temperature.. na pag tumaas ang pressure ay tataas din ang temperature..

sa example na pinakita ko na ang apoy or heat [fire or heater] ay in-aplly mo sa refrigerant ay magbibigay ito ng heat sa refrigerant or freon.. na pag umiinit naman yun ay magkakaron ng high pressure pra i push nya ang freon papunta sa expansion devices.. expansion device ay npkahalaga sa system kasi d2 ng kakaron ng pressure drop.. expand nya ang particles ng refrigerant pra mgkaron ng pressure drop from condensation.. then after nun punta ng evaporator yun.. kelangan sya i expand dahil para mas madali sya mag evaporate sa pamamagitan ng mga pagkain natin or mga tubig na nilalagay sa refrigerated compartment.. yung heat load na nggagaling sa pagkain ay yun ang nkakatulong pra mag evaporate lahat ng refrigerant sa evaporator..

[about naman sa design mo]
Thermoelectric modules are solid-state devices (no moving parts) that convert electrical energy into a temperature gradient, known as the "Peltier effect" or convert thermal energy from a temperature gradient into electrical energy, the "Seebeck effect."

nagamit na po yan ng panasonic.. kaso ang problema jan ay ang mga technician ng ref or water dispenser ay hnd maarok ng kanilang pag iisip ang mga electronics components jan.. kaya hnd din sya economical gamitin kasi nagiging disposable ang appliances.. sya nga po pala yung design ng panasonic na halos parehas din ng principle na ginawa mo ay gumamit pa din ng [refrigerant] ang pagkakaiba nga lng eh hnd freon ang ginamit nila dahil ang freon ay sumasama sa ambient air pag napakawalan..

pero hnd pa din mawawala sa system ng pag papalamig ang refrigerant.. hindi lng naman freon ang ginagamit na refrigerant [refrigerant ay ginagamit bilang heat transfer] ang ginamit ng panasonic na refrigerant sa design nila ay amonia [50% amonia and 50% water] dahil ang amonia ay highly flamable kaya hnd din sya economical gamitin.. pero ang iba naman ginagamit ay brine as secondary refrigerant.. ginagamit din sya bilang heat transfer.. pero kelangan pa din ng primary refrigerant tuland ng freon or amonia pra mapalamig ang brine yung brine po ay kadalasan ay ethelyn glycol pero mahal yan.. kaya yung iba ginagamit nlng ay mixed of water and salt as a brine [secondary refrigerant]..

thanks @ brian_po

may ckt design ka ba ng sa panasonic na yan? hirap kasi ako dito sa thermoelectric module na to, but im still determined to make this possible.  Masyado man ako ambitious but ive already consulted some experts from tellurex and other TEC manufacturer. And as of now, they are already doing some experiements about my project.  And they toldme that they made it already. in this project,  I've made a hard time in doing all the computations such as the heat loads, the power supply to use with the proper current rating, the size and design of the heatsink  and etc., all these parameters were somewhat very vital to the design of the TEC water cooler.
So kung sino man jan ang gumawa na nito dati, please give me some details.

sir intoy..
yung design ng panasonic kasi na yun eh hnd na market d2 sa pinas..
sumikat yun last 5yrs sa japan.. saka wla ako schematics nun kasi sobra critical yung ckt nya..
dami IC tapos yung main board nya mas malaki pa sa main board ng TV.. malabo tau makakuha ng schematics nun kasi confidential yun eh, cguro kung may magreply sa thread na ito na sa panasonic work bka sakali mabigyan nya tau ng schematics.. kung samsung lng yan complete ako sa schematics lahat ng models.. hahaha pero confidential yun eh lolz..

sabi ng tatay ko nakakita na daw sya ng ganyan na ref :D mga wayback 1970's :o hehehehehehe nilalagyan daw ng kerosene nakita nya daw yan sa mga kano sa base :D

buhayin ko lang ito, may ipinagbibili kasi sa kabila  ;D

up!

kung ilalgay ko sa exhaust pipe ng sasakyan ang Thermoelectric Pad at air cool (w/ alum fins) ang other side niya, ilang watts naman kaya ang makukuha ko?

yung ref de uling may ganyan na daw noon, kwento ng tito ko kailangan daw palagi sinisindihan, siya pa daw yung tga lagay ng uling ;D
hindi ko yun pinaniwalaan, until ngayon na nalaman ko na pwede pala yun, pangatarungan ko kasi, bakit pinapainit yung tanke ng ref, at lumalamig naman yung loob ??? ;D

Peltiers have low to medium efficiencies (I don't exactly know so don't ask me) so they don't have yet the technology to overtake mechanical run refrigeration.   :-[

hi ate gwenda, ito nalng tanong ko, ikaw ba yan nsa abatar nyo?  ;D

pwede kaya bilad sa araw ang kabilang side w/ heatsinks tapos heat insulate ang other side ano sa palagay nyo ate?
