Waxqabadka qaboojinta ee thermoelectric

Xisaabinta waxqabadka qaboojinta heerkulka-kulka:

Kahor intaadan isticmaalin qaboojinta kuleyliyaha, si loo sii fahmo waxqabadkeeda, dhab ahaantii, dhammaadka qabow ee module-ka peltier, modules-ka thermoelectric, wuxuu nuugaa kulaylka ka soo baxa hareeraha, waxaa jira laba: mid waa kulaylka joule Qj; kan kalena waa kulaylka gudbinta Qk. Haddaydu waxay dhex martaa gudaha curiyaha thermoelectric si ay u soo saarto kulaylka joule, kala bar kulaylka joule waxaa loo gudbiyaa dhamaadka qabow, qeybta kalena waxaa loo gudbiyaa dhamaadka kulul, kulaylka gudbintana waxaa loo gudbiyaa dhamaadka kulul ilaa dhamaadka qabow.

Wax soo saarka qabow Qc=Qπ-Qj-Qk

= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)

Halka R uu matalayo iska caabinta guud ee lammaane iyo K uu matalayo wadar ahaan isku-xidhka kulaylka.

Kulaylka laga saaray dhamaadka kulul Qh=Qπ+Qj-Qk

= (2p-2n).Th.I+1/2I²R-K (Th-Tc)

Waxaa laga arki karaa labada qaacido ee kor ku xusan in awoodda korontada ee la gelinayo ay tahay farqiga saxda ah ee u dhexeeya kulaylka uu kala diro dhammaadka kulul iyo kulaylka uu nuugo dhammaadka qabow, kaas oo ah nooc ka mid ah "bamka kulaylka":

Qh-Qc=I²R=P

Qaaciddada kor ku xusan, waxaa lagu soo gabagabeyn karaa in kulaylka Qh ee ay soo saarto lammaane koronto ku shaqeeya oo ku sugan dhammaadka kulul uu la mid yahay wadarta awoodda korontada ee la geliyo iyo wax soo saarka qabow ee dhammaadka qabow, taas beddelkeedana, waxaa lagu soo gabagabeyn karaa in wax soo saarka qabow ee Qc ​​uu la mid yahay farqiga u dhexeeya kulaylka uu soo saaro dhammaadka kulul iyo awoodda korontada ee la geliyo.

Qh=P+Qc

Qc=Qh-P

Habka xisaabinta ee awoodda qaboojinta kulaylka ugu badan

A.1 Marka heerkulka dhamaadka kulul yahay 27℃±1℃, farqiga heerkulka waa △T=0, iyo I=Imax.

Awoodda qaboojinta ugu badan ee Qcmax(W) waxaa lagu xisaabiyaa qaacidada (1): Qcmax=0.07NI

Halka N - logarithm-ka qalabka kuleylka, I - farqiga heerkulka ugu badan ee qalabka (A).

A.2 Haddii heerkulka dusha sare ee kulul uu yahay 3~40℃, awoodda qaboojinta ugu badan ee Qcmax (W) waa in la saxaa iyadoo loo eegayo qaacidada (2).

Qcmax = Qcmax×[1+0.0042(Th--27)]

(2) Qaaciddada: Qcmax — heerkulka dusha sare ee kulul Th=27℃±1℃ awoodda qaboojinta ugu badan (W), Qcmax∣Th — heerkulka dusha sare ee kulul Th — awoodda qaboojinta ugu badan (W) heerkulka la cabbiray laga bilaabo 3 ilaa 40℃
