Gabatarwa Zuwa Ma'aunin sanyi na Thermoelectric
Fasahar thermoelectric fasaha ce ta sarrafa zafi mai aiki bisa tasirin Peltier. JCA Peltier ne ya gano shi a cikin 1834, wannan al'amari ya haɗa da dumama ko sanyaya mahaɗin kayan wutan lantarki guda biyu (bismuth da telluride) ta hanyar wucewa ta hanyar junction. Yayin aiki, kai tsaye yana gudana ta hanyar tsarin TEC yana haifar da canja wurin zafi daga wannan gefe zuwa wancan. Ƙirƙirar gefen sanyi da zafi. Idan an juya jagorancin halin yanzu, ana canza sassan sanyi da zafi. Hakanan ana iya daidaita ƙarfin sanyaya ta ta canza yanayin aiki. Mai sanyaya mataki ɗaya na al'ada (Hoto 1) ya ƙunshi faranti biyu na yumbu tare da p da n-type semiconductor abu (bismuth,telluride) tsakanin faranti yumbura. Abubuwan abubuwan semiconductor an haɗa su ta hanyar lantarki a cikin jeri da thermally a layi daya.
Thermoelectric sanyaya module, Peltier na'urar, TEC kayayyaki za a iya la'akari a matsayin wani irin m-jihar thermal makamashi famfo, kuma saboda da ainihin nauyi, size da kuma kudi na dauki, shi ne sosai dace da za a yi amfani da a matsayin wani ɓangare na inbuilt sanyaya tsarin (saboda iyakance sarari). Tare da abũbuwan amfãni irin su shiru aiki, shatter hujja, girgiza juriya, tsawon amfani rayuwa da kuma sauki tabbatarwa, zamani thermoelectric sanyaya module, peltier na'urar, TEC kayayyaki da fadi da kewayon aikace-aikace a cikin filayen soja kayan aiki, jirgin sama, jirgin sama, likita magani, annoba rigakafin, gwaji na'ura, mabukaci kayayyakin (ruwa mai sanyaya, mota sanyaya, hotel firiji, giya mai sanyaya, sirri zafi, da dai sauransu mini).
A yau, saboda ƙananan nauyinsa, ƙananan girmansa ko iya aiki da ƙananan farashi, ana amfani da sanyaya thermoelectric a cikin magunguna, kayan aikin magunguna, jirgin sama, sararin samaniya, soja, tsarin spectrocopy, da samfurori na kasuwanci (kamar ruwan zafi & ruwan sanyi, firiji mai ɗaukar hoto, carcooler da sauransu).

Gabatar da Formula na aikace-aikace zuwa tsarin TEC
Qc= 2N[a(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
△Tmax= Th+ 273 + κ/σα² x [1-√2σα²/κx (T)h+273) + 1.
Imax =κS/ Lαx [√2σα²/κx (Th+273) + 1-1]
Iεmax =(Th- Tc/ L (√1+0.5σα²(546+ Th- Tc)/ κ-1)
