Gabatarwa ga tsarin sanyaya na Thermoelectric
Fasahar Thermoelectric wata dabara ce ta sarrafa zafi mai aiki bisa ga tasirin Peltier. JCA Peltier ne ya gano ta a shekarar 1834, wannan lamari ya ƙunshi dumama ko sanyaya mahaɗin kayan thermoelectric guda biyu (bismuth da telluride) ta hanyar wucewar wutar lantarki ta hanyar mahaɗin. A lokacin aiki, wutar lantarki kai tsaye tana gudana ta cikin tsarin TEC wanda ke haifar da canja wurin zafi daga gefe ɗaya zuwa ɗayan. Ƙirƙirar gefen sanyi da zafi. Idan aka juya alkiblar wutar, ana canza ɓangarorin sanyi da zafi. Hakanan ana iya daidaita ƙarfin sanyaya ta ta hanyar canza wutar lantarki. Mai sanyaya mataki ɗaya na yau da kullun (Hoto na 1) ya ƙunshi faranti biyu na yumbu tare da kayan semiconductor na p da n-type (bismuth, telluride) tsakanin faranti na yumbu. Abubuwan kayan semiconductor suna da alaƙa ta lantarki a jere kuma a layi ɗaya a cikin yanayin zafi.
Module ɗin sanyaya na Thermoelectric, na'urar Peltier, ana iya ɗaukar module ɗin TEC a matsayin nau'in famfon makamashin zafi mai ƙarfi, kuma saboda ainihin nauyinsa, girmansa da kuma saurin amsawar sa, ya dace sosai a yi amfani da shi a matsayin wani ɓangare na tsarin sanyaya da aka gina (saboda ƙarancin sarari). Tare da fa'idodi kamar aiki mai natsuwa, hana fashewa, juriyar girgiza, tsawon rai mai amfani da kuma sauƙin gyarawa, na'urar sanyaya na thermoelectric ta zamani, na'urar peltier, module ɗin TEC suna da aikace-aikace iri-iri a fannoni na kayan aikin soja, jiragen sama, jiragen sama, maganin likita, rigakafin annoba, na'urar gwaji, kayayyakin mabukaci (na'urar sanyaya ruwa, na'urar sanyaya mota, firiji na otal, na'urar sanyaya giya, na'urar sanyaya ta sirri, na'urar barci mai sanyi & zafi, da sauransu).
A yau, saboda ƙarancin nauyi, ƙaramin girma ko ƙarfinsa da ƙarancin farashi, ana amfani da sanyaya thermoelectric sosai a fannin likitanci, kayan aikin magunguna, jiragen sama, sararin samaniya, tsarin soji, tsarin spectrocopy, da kayayyakin kasuwanci (kamar na'urar rarraba ruwan zafi da sanyi, firiji mai ɗaukuwa, na'urar sanyaya mota da sauransu)

Qc= 2N[α(T)c+273)-LI²/2σS-κs/Lx(T)h- 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
△Tmatsakaicin= Th+ 273 + κ/σα² x [1-√2σα²/κx (T)h+273) + 1]
Imatsakaicin =κS/ Lαx [√2σα²/κx (T)h+273) + 1-1]
Iεmatsakaicin =ασS (T)h- Tc) / L (√1+0.5σα²(546+ Th- Tc)/ κ-1)
