Xisaabinta Waxqabadka Qalinka ee Thermoelcric
Kahor intaadan adeegsan qaboojinta heerkulka heerkulka, si aad u ogaato wax qabadkeeda, dhab ahaantii, dhamaadka qabow ee moduleka pelmeier, moduleles thermolecticric, waxaa jira labo: mid waa kuleylka joule QJ; Midda kale waa durdur kuleylka Qk. Wakhtiga hadda socda ee ka dhex dhacaya gudaha thermolectric-ka si loo soo saaro kuleylka youle, kala badh kuleylka joule waxaa loo gudbiyaa dhamaadka qabow, badhka kale waxaa lagu kala qaadaa dhamaadka kulul, oo kulaylka wareega ayaa lagu kala qaadaa dhamaadka kulul dhamaadka.
Wax soosaarka qabow QC = qπ-qj-qk
= (2p-2n) .tc.i-1j²r-k (th-tc)
Meesha r metelo isugeynta isugeynta lammaanaha iyo k waa wadarta guud ee kuleylka.
Kuleylka ayaa laga soo saaray dhamaadka kulul ee QH = Qπ + qj-qk
= (2p-2n) ..i + 1/I²r-k (th-tc)
Waxaa lagu arki karaa labada nooc ee kor ku xusan in fikradda korantada ay tahay farqiga u dhexeeya kuleylka ay kululeeyaan dhamaadka kulul iyo kuleylka uu nuugo dhamaadka qabowga, taas oo ah nooca "matoorka kuleylka":
Q-qc = i²r = p
Laga soo bilaabo qaaciddada kor ku xusan, waxaa lagu soo gabagabeyn karaa in kuleylka QH ee lammaanaha korantada ku yaal dhamaadka kulul uu u siman yahay isugeynta awoodda korantada iyo soosaarka qabow ee dhamaadka qabow, iyo in la soo gabagabeeyo. Soosaarka qabow QC waxay la mid tahay farqiga u dhexeeya kuleylka uu kuleejka kulul iyo korantada korantada ee gelinta.
Qh = p + qc
Qc = qh-p
Habka Xisaabinta ee ugu badan ee kuleylka ugu badan ee kuleylka ah
A.1 Marka heerkulka dhamaadka kulul uu yahay 27 ℃ ± 1 ℃, farqiga heerkulka ah waa △ t = 0, iyo I Imax.
Awoodda ugu badan ee qaboojinta Qcmax (W) waxaa loo xisaabiyaa iyadoo la raacayo qaaciddada (1): qcmax = 0.07ni
Meesha n - logarithm ee aaladda heerkulka heerkulka, aniga - farqiga heerkulka ugu sarreeya ee aaladda (a).
A.2 Haddii heerkulka dusha kulul uu yahay 3 ~ 40 ℃, awoodda ugu badan ee qaboojinta Qcmax (W) waa in la saxo sifooyin (2).
Qcmax = qcmax × [1 + 0.0042 (27)
(2) Qaaciddada: Qcmax - heerkulka dusha kulul ee th = 27 ℃ ± 1 ℃ Awoodda qaboojinta ugu badan (W), Qcmax thrustar dusha sare ee kuleylka (W) ee heerkulka qaboojiyaha ee 3 ilaa 40 ℃
