Palo ea ts'ebetso ea ho pholisa ea thermoelectric:
Pele o sebedisa thermoelectric cooling, ho utlwisisa tshebetso ya yona haholoanyane, ha e le hantle, pheletso e batang ya mojule wa peltier, di-module tsa thermoelectric, e monya mocheso ho tswa ho tse potolohileng, ho na le tse pedi: e nngwe ke joule heat Qj; e nngwe ke conduction heat Qk. Motlakase o feta ka hare ho karolo ya thermoelectric ho hlahisa mocheso wa joule, halofo ya mocheso wa joule e fetisetswa pheletsong e batang, halofo e nngwe e fetisetswa pheletsong e chesang, mme mocheso wa conduction o fetisetswa ho tloha pheletsong e chesang ho ya pheletsong e batang.
Tlhahiso e batang Qc=Qπ-Qj-Qk
= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)
Moo R e emelang khanyetso e felletseng ea para 'me K ke phetisetso e felletseng ea mocheso.
Mocheso o fedile ho tloha pheletsong e chesang Qh=Qπ+Qj-Qk
= (2p-2n).Th.I+1/2I²R-K (Th-Tc)
Ho ka bonoa ho tsoa liforomong tse peli tse kaholimo hore matla a motlakase a kenang ke phapang e nepahetseng pakeng tsa mocheso o qhalakantsoeng ke ntlha e chesang le mocheso o monngoang ke ntlha e batang, e leng mofuta oa "pompo ea mocheso":
Qh-Qc=I²R=P
Ho tsoa foromong e ka holimo, ho ka fihlelletsoa qeto ea hore mocheso Qh o ntšoang ke banyalani ba motlakase pheletsong e chesang o lekana le kakaretso ea matla a motlakase a kenoang le tlhahiso e batang ea pheletso e batang, 'me ka lehlakoreng le leng, ho ka fihlelletsoa qeto ea hore tlhahiso e batang Qc e lekana le phapang pakeng tsa mocheso o ntšoang ke pheletso e chesang le matla a motlakase a kenoang.
Qh=P+Qc

Mokhoa oa ho bala matla a phahameng a ho pholisa a thermoelectric
A.1 Ha mocheso o qetellong ya mocheso Th e le 27℃±1℃, phapang ya mocheso ke △T=0, mme I=Imax.
Matla a ho pholisa a phahameng ka ho fetisisa Qcmax(W) e baloa ho latela foromo (1): Qcmax=0.07NI
Moo N — logarithm ea sesebelisoa sa thermoelectric, I — phapang e phahameng ka ho fetisisa ea mocheso oa sesebelisoa (A).
A.2 Haeba mocheso oa bokaholimo bo chesang e le 3 ~ 40℃, matla a ho pholisa a phahameng ka ho fetisisa Qcmax (W) a lokela ho lokisoa ho latela foromo (2).
Qcmax = Qcmax×[1+0.0042(Th--27)]
(2) Ka mokhoa o latelang: Qcmax — mocheso o chesang wa bokaholimo Th=27℃±1℃ matla a ho pholisa a phahameng ka ho fetisisa (W), Qcmax∣Th — mocheso o chesang wa bokaholimo Th — matla a ho pholisa a phahameng ka ho fetisisa (W) mochesong o lekantsoeng ho tloha ho 3 ho isa ho 40℃
