1. Whakatauhia te kawenga wera
Ko te kawenga wera e pā ana ki te nui o te wera e tika ana kia tangohia hei whakaheke i te pāmahana o te ūnga whakamatao ki tētahi taumata kua tohua i raro i tētahi taiao pāmahana, ko te waeine ko W (watt). Ko ngā kawenga wera ko ngā kawenga hohe, ngā kawenga kore mahi, me ō rātou huinga. Ko te kawenga wera hohe ko te kawenga wera i hangaia e te ūnga whakamatao tonu. Ko te kawenga wera kore mahi ko te kawenga wera i puta mai i te irahiko o waho, te kawe hiko me te kawe hiko. Te tātaitanga kawenga hohe
Qactive = V2/R = VI = I2R;
Qkaha = Kawenga wera kaha (W);
V = Te ngaohiko e pā ana ki te ūnga whakamatao (V);
R = Te ātete o te ūnga whakamatao;
I = Te iahiko e rere ana i roto i te ūnga kua whakamatao (A)
Ko te kawenga wera hihi ko te kawenga wera e tukuna ana ki te mea ūnga mā te hihi hikohiko. Te tātai tatau:
Qrad = F es A (Tamb4 – Tc4);
Qrad = Utaina wera hihi (W);
F = tauwehenga āhua (uara kino rawa = 1);
e = te kaha whakaputa (uara kino rawa atu = 1);
s = te pūmau Stefan-Boltzmann (5.667 X 10-8W/m² k4);
A = Te horahanga mata whakamatao (m²);
Tamb = Te Pāmahana Āhua (K);
Tc = TEC – Te pāmahana matao o te pito (K).
Ko te kawenga wera āwhiowhio ko te kawenga wera e tukuna ana e te wai e rere ana i roto i te mata o te mea ūnga mai i waho. Ko te tātai tatau ko:
Qconv = hA (Tair – Tc);
Qconv = Te kawenga wera whakawhiti (W)
h = Tauwehenga whakawhiti wera āwhata (W/m² °C) (te uara noa o te papa wai i te hau paerewa kotahi) = 21.7 W/m² °C;
A = Te horahanga o te mata (m²);
Tair = Te pāmahana ambient (°C);
Tc = Te pāmahana matao o te pito (°C);
Ko te kawenga wera kawe ko te kawenga wera e whakawhitia ana mai i waho mā roto i ngā mea e pā ana ki te mata o te mea e whaia ana. Ko te tātai tatau ko:
Qcond =k A DT/L;
Qcond = Kawenga wera whakawhiti (W);
k = Te kawe wera o te rauemi kawe wera (W/m °C);
A = Te horahanga whakawhiti-wāhanga o te rauemi kawe wera (m²);
L = Te roa o te ara kawe wera (m)
DT = Te rerekētanga pāmahana o te ara kawe wera (°C) (e pā ana ki te pāmahana taiao, ki te pāmahana totohu wera rānei, tangohia te pāmahana pito matao.)
Mō te kawenga wera whakakotahi o te kawe me te kawe, ko te tātai tatau ko:
Q hāngū = (A x DT)/(x/k + 1/h);
Qpānga = Kawenga wera (W);
A = Te horahanga mata katoa o te anga (m2);
x = Te matotoru o te paparanga whakamarumaru (m)
k = Te kawe wera o te ārai (W/m °C);
h = Tauwehenga whakawhiti wera āwhata (W/m² °C)
DT = Rerekētanga pāmahana (°C).
2. Tātaihia te kawenga wera katoa
Mā te taahiraa tuatahi, ka taea e tātou te tatau i te kawenga wera katoa o te ūnga whakamatao.
Me kī, i roto i te kaupapa tuturu, ko te kawenga wera hohe ko 8W, ko te kawenga wera hihi ko 0.2W, ko te kawenga wera whakawhiti ko 0.8W, ko te kawenga wera kawe hiko ko 0W, ā, ko te kawenga wera katoa ko 9W.
3. Tautuhia te pāmahana
Tautuhia te rerekētanga o te pāmahana pito wera, te pāmahana pito makariri me te pāmahana whakamatao o te pepa whakamatao. Me kī i roto i te kaupapa tuturu, ko te pāmahana taiao he 27°C, ko te pāmahana whakamatao e hiahiatia ana he -8°C, ā, ko te rerekētanga pāmahana whakamatao DT=35°C
Ki te whakaaro ko te tapeke o te kawenga wera o te ūnga whakamatao e whakatauhia ana ko te 9W i runga i te whakatau tata o mua, ka taea te whiwhi i te Qmax tino pai ko te 9/0.25=36W, me te Qmax mōrahi ko te 9/0.45=20. Rapua te rārangi hua a Beijing Huimao Cooling Equipment Co.,Ltd mō ngā kōwae whakamatao thermoelectric, ngā kōwae peltier, ngā taputapu peltier, ngā kōwae peltier elements.TEC, ā, kimihia ngā hua me te Qmax mai i te 20 ki te 36.
