Intangiriro ku buryo bwo gukonjesha bwa Thermoelectric
Ikoranabuhanga rya Thermoelectric ni uburyo bwo gucunga ubushyuhe bushingiye ku ngaruka za Peltier. Yavumbuwe na JCA Peltier mu 1834, iki kintu kijyanye no gushyushya cyangwa gukonjesha aho ibikoresho bibiri bya thermoelectric (bismuth na telluride) bihurira binyuze mu gucisha umuriro mu ihuriro. Mu gihe cy'imikorere, umuriro utaziguye unyura muri module ya TEC bigatuma ubushyuhe bwimurwa kuva ku ruhande rumwe ujya ku rundi. Gukora uruhande rukonje n'urushyuhe. Iyo icyerekezo cy'umuriro gisubiwemo, impande zikonje n'izishyushye zirahinduka. Imbaraga zayo zo gukonjesha nazo zishobora guhindurwa hakoreshejwe guhindura umuriro wayo w'imikorere. Igikoresho gikonjesha kimwe (Ishusho ya 1) kigizwe n'amasahani abiri ya ceramic afite ibikoresho bya semiconductor bya p na n (bismuth, telluride) hagati y'amasahani ya ceramic. Ibintu bigize ibikoresho bya semiconductor bihuzwa n'amashanyarazi mu buryo bukurikiranye kandi mu buryo bujyanye n'ubushyuhe.
Module yo gukonjesha ya Thermoelectric, Peltier device, TEC modules zishobora gufatwa nk'ubwoko bwa pompe y'ingufu z'ubushyuhe, kandi bitewe n'uburemere bwayo nyabwo, ingano yayo n'umuvuduko wayo, irakwiriye cyane gukoreshwa nk'igice cya sisitemu zo gukonjesha zubatswemo (kubera ko umwanya utoroshye). Ifite ibyiza nko gukora ituje, kudacika intege, kudahungabana, kumara igihe kirekire kandi byoroshye kuyibungabunga, module igezweho yo gukonjesha ya thermoelectric, module za peltier, TEC zifite ikoreshwa rinini mu bijyanye n'ibikoresho bya gisirikare, indege, indege, ubuvuzi, gukumira icyorezo, ibikoresho by'igerageza, ibikoresho bikoreshwa n'abaguzi (amazi akonjesha, icyuma gikonjesha imodoka, firigo ya hoteli, icyuma gikonjesha divayi, icyuma gikonjesha gito, icyuma gikonjesha n'ubushyuhe, nibindi).
Muri iki gihe, kubera uburemere bwayo buke, ingano nto cyangwa ubushobozi bwayo hamwe n'igiciro gito, gukonjesha amashanyarazi bikoreshwa cyane mu bikoresho by'ubuvuzi, imiti, indege, indege, igisirikare, sisitemu za spectrokopi, n'ibindi bicuruzwa by'ubucuruzi (nk'icyuma gitanga amazi ashyushye n'akonje, firigo zigendanwa, icyuma gikonjesha imodoka n'ibindi)

Intangiriro y'uburyo bwo gukoresha formula muri module ya TEC
Qc= 2N[α(Tc+273)-LI²/2σS-κs/Lx(Th- Tc) ]
△T= [ Iα(Tc+273)-LI/²2σS] / (κS/L + I α]
U = 2 N [ IL /σS + α (Th- Tc)]
ε = Qc/UI
Qh= Qc + IU
△Tumubare ntarengwa= Th+ 273 + κ / σα² x [1-√2σα² / κx (T.h+273) + 1]
Intarengwa =κS/ Lax [√2σα²/κx (Th+273) + 1-1]
Iεntarengwa =ασS (Th- Tc) / L (√1+0.5σα² (546+ Th- Tc)/ κ-1)
