Tātaitanga mahi whakamatao hiko-wera:
I mua i te whakamahinga o te whakamatao hiko wera, kia mārama ake ai ki tana mahi, ko te mea pono, ko te pito makariri o te kōwae peltier, arā, ngā kōwae hiko wera, ka mimiti i te wera mai i te taha e karapoti ana, e rua ngā momo: ko tētahi he wera joule Qj; ko tētahi he wera kawe Qk. Ka haere te iahiko mā roto i te wāhanga hiko wera hei whakaputa i te wera joule, ko te haurua o te wera joule ka tukuna ki te pito makariri, ko tētahi atu haurua ka tukuna ki te pito wera, ā, ka tukuna te wera kawe mai i te pito wera ki te pito makariri.
Te whakaputanga makariri Qc=Qπ-Qj-Qk
= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)
Ko R te ātete katoa o te takirua, ā, ko K te kawe wera katoa.
Te wera i marara mai i te pito wera Qh=Qπ+Qj-Qk
= (2p-2n).Th.I+1/2I²R-K (Th-Tc)
Ka kitea mai i ngā tātai e rua i runga ake nei ko te mana hiko whakauru ko te rerekētanga tonu i waenga i te wera e marara ana i te pito wera me te wera e mimitihia ana e te pito makariri, he momo "papu wera" tēnei:
Qh-Qc=I²R=P
Mai i te tātai i runga ake nei, ka taea te whakatau ko te wera Qh e tukuna ana e te takirua hiko i te pito wera he ōrite ki te tapeke o te mana hiko whakauru me te putanga matao o te pito matao, ā, i tetahi atu taha, ka taea te whakatau ko te putanga matao Qc he ōrite ki te rerekētanga i waenga i te wera e tukuna ana e te pito wera me te mana hiko whakauru.
Qh=P+Qc
Qc=Qh-P
Tikanga tatau i te mana whakamatao thermoelectric mōrahi
A.1 Ina 27℃±1℃ te pāmahana i te pito wera o Th, ko te rerekētanga pāmahana he △T=0, ā, ko I=Imax.
Ka tatauhia te mana whakamatao mōrahi Qcmax(W) e ai ki te tātai (1): Qcmax=0.07NI
Ko N — te logarithm o te pūrere thermoelectric, I — te iahiko rerekētanga pāmahana mōrahi o te pūrere (A).
A.2 Mena ko te pāmahana o te mata wera he 3~40℃, me whakatika te mana whakamatao mōrahi Qcmax (W) kia rite ki te tauira (2).
Qcmax = Qcmax×[1+0.0042(Th--27)]
(2) I roto i te tātai: Qcmax — pāmahana mata wera Th=27℃±1℃ mana whakamatao mōrahi (W), Qcmax∣Th — pāmahana mata wera Th — mana whakamatao mōrahi (W) i te pāmahana inehia mai i te 3 ki te 40℃
