Chiyambi cha gawo loziziritsa la Thermoelectric
Ukadaulo wa Thermoelectric ndi njira yogwiritsira ntchito kutentha pogwiritsa ntchito mphamvu ya Peltier. JCA Peltier inapezeka mu 1834, ndipo izi zimaphatikizapo kutentha kapena kuzizira kwa malo olumikizirana a zinthu ziwiri za thermoelectric (bismuth ndi telluride) podutsa mphamvu kudzera mu malo olumikizirana. Panthawi yogwira ntchito, mphamvu yolunjika imayenda kudzera mu TEC module zomwe zimapangitsa kuti kutentha kusamutsidwe kuchokera mbali imodzi kupita ku ina. Kupanga mbali yozizira ndi yotentha. Ngati njira ya mphamvu yasintha, mbali yozizira ndi yotentha imasinthidwa. Mphamvu yake yozizira imathanso kusinthidwa mwa kusintha mphamvu yake yogwirira ntchito. Choziziritsira chachizolowezi cha single stage (Chithunzi 1) chimakhala ndi mbale ziwiri za ceramic zokhala ndi zinthu za semiconductor za p ndi n (bismuth, telluride) pakati pa mbale za ceramic. Zinthu za semiconductor zimalumikizidwa ndi magetsi motsatizana komanso mofanana.
Module yoziziritsira ya Thermoelectric, chipangizo cha Peltier, ma module a TEC amatha kuonedwa ngati mtundu wa pampu yamphamvu yotenthetsera, ndipo chifukwa cha kulemera kwake kwenikweni, kukula kwake, komanso liwiro lake, ndi yoyenera kugwiritsidwa ntchito ngati gawo la makina oziziritsira omwe adamangidwa mkati (chifukwa cha kuchepa kwa malo). Ndi zabwino monga kugwira ntchito chete, kulephera kusweka, kukana kugwedezeka, kukhala ndi moyo wautali komanso kukonza kosavuta, module yamakono yoziziritsira ya thermoelectric, chipangizo cha peltier, ma module a TEC ali ndi ntchito zambiri m'magawo a zida zankhondo, ndege, ndege, chithandizo chamankhwala, kupewa miliri, zida zoyesera, zinthu zogulira (zoziziritsira madzi, choziziritsira magalimoto, firiji ya hotelo, choziziritsira vinyo, choziziritsira chaching'ono chaumwini, choziziritsira chozizira & chotentha, ndi zina zotero).
Masiku ano, chifukwa cha kulemera kwake kochepa, kukula kwake kochepa kapena mphamvu yake komanso mtengo wake wotsika, kuziziritsa kwa thermoelectric kumagwiritsidwa ntchito kwambiri mu zida zamankhwala, zida zamankhwala, ndege, ndege, zankhondo, machitidwe a spectrocopy, ndi zinthu zamalonda (monga chotulutsira madzi otentha ndi ozizira, mafiriji onyamulika, choziziritsira galimoto ndi zina zotero)

Chiyambi cha Mafomula ogwiritsira ntchito ku gawo la 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
△Tkuchuluka= Th+ 273 + κ/σα² x [1-√2σα²/κx (Th+273) + 1]
Ikuchuluka =κS/ Lax [√2σα²/κx (Th+273) + 1-1]
Iεkuchuluka =ασS (Th- Tc) / L (√1+0.5σα²(546+ Th- Tc)/ κ-1)
