He tino uaua ake te kōwhiri i ngā kōwae whakamatao hiko maha-wāhanga (pūrere peltier maha-wāhanga) i te kōwhiri i ngā kōwae whakamatao hiko kotahi-wāhanga noa, arā, ko te peltier, nā te mea he hanganga "cascade" tōna, ā, he nui ake ngā whakaritenga mō te whakahaere wera me te taurite tawhā hiko.
Hipanga 1: Tautuhia ngā whakaritenga matua (ngā tikanga whakauru)
I mua i te titiro ki ngā tauira motuhake, me whakatau ko ēnei ngā "tohu mārō" e toru hei pūtake mō te kōwhiringa:
Te pāmahana ūnga (Tc) me te pāmahana pito wera (Th):
I tehea pāmahana e tika ana kia eke ki te pito makariri? (Hei tauira: -40°C)
He aha te kaha mōrahi o te pito wera ki te tuku wera? (I hangaia i te nuinga o te wā ko te 25°C, 50°C rānei).
Tātaihia te rerekētanga pāmahana (ΔT): ΔT = Th – Tc. Ko ngā maramara maha-wāhanga te tikanga e whakamahia ana i ngā horopaki ina neke ake te ΔT i te 70°C.
Kawenga wera (Qc):
E hia te wattage (W) ka tukuna e te mea hei whakamatao?
Ki te kore koe e tino mōhio, me tatau te wera katoa e whakaputaina ana e te mea, tae atu ki te wera o roto, te wera kawe hiko, me te wera irahiko.
Te wāhi e wātea ana me te pūngao hiko:
Ngā herenga rahi tāutanga (te roa me te whānui)?
He pūmau te ngaohiko o te pūhiko (pēnei i te 12V, 24V) he pūmau rānei te iahiko? He aha te rohenga iahiko mōrahi?
Hipanga 2: Kia mārama ki ngā tawhā matua (ngā tohu matua)
He hononga kaha tō ngā tawhā o ngā kōwae peltier maha-wāhanga, me ngā taputapu pletier maha-wāhanga. Kia arotahi ki ngā mea e whā e whai ake nei:
Te maha o ngā wāhanga (Ngā Wāhanga):
Koinei te āhuatanga tino motuhake o ngā kōwae hiko wera maha-wāhanga, arā, ngā huānga peltier. I te nuinga o te wā, e rua ngā wāhanga, e toru ngā wāhanga, e ono rānei ngā wāhanga o te kōwae whakamatao hiko wera.
Ture matua: Ka nui ake ngā wāhanga, ka nui ake te rerekētanga pāmahana ka taea te whakatutuki, engari ka iti ake te kaha whakamatao (Qc) ā, ka teitei ake te utu. Ko te tikanga, ko te rerekētanga pāmahana mōrahi o te wāhanga kotahi he tata ki te 60-70°C. Mena e hiahiatia ana he pāmahana -80°C, iti iho rānei, me whiriwhiri he kōwae peltier maha-wāhanga.
Te kaha whakamatao mōrahi (Qmax):
E pā ana ki te kaha mōrahi o te mimiti wera ina he 0 te rerekētanga pāmahana.
Whakaaro whiriwhiri: He iti ake te kaha whakamatao tuturu (Qc) i te wā e whakamahia ana i te Qmax. Ko te tikanga kia 1.3 ki te 2 ngā wā o te nui o te Qmax i tō kawenga wera tuturu, kia waiho ai he tawhiti hei whakarite i te whai huatanga me te roa o te whakamahinga.
Te rerekētanga pāmahana mōrahi (ΔTmax):
E pā ana ki te rerekētanga pāmahana mutunga ka taea e te waeine whakamatao hiko wera, te huānga peltier te whakatutuki (ina he 0 te kaha whakamatao).
Whakaaro kōwhiringa: Me 10-20% teitei ake te ΔTmax kua tīpakohia i te rerekētanga pāmahana tuturu e hiahiatia ana e koe.
Ngaohiko me te au (Vmax / Imax):
He nui te ātete ā-roto o te waeine whakamatao hiko maha-wāhanga, te waeine TEC, ā, tera pea he teitei te ngaohiko (pēnei i te 24V, 48V, neke atu rānei), engari he iti noa te iahiko. Kia tino mohio ka taea e tō pūtake hiko te taraiwa.
Hipanga 3: Whakamahia te pihi mahi (taurite tika)
Koinei te taahiraa tino nui. Kaua e whakawhirinaki noa ki ngā uara mōrahi kua whakahuatia i roto i te pepa whakatakotoranga!
He kore-rārangi te mahi a te kōwae whakamatao hiko-maha-wāhanga kōwae hiko-maha.
Whakatauhia te pūwāhi whakahaere: Mō te rerekētanga pāmahana ūnga (ΔT) me te kaha whakamatao ūnga (Qc), tirohia te kauwhata kōpiko.
Kimihia te iahiko tino pai (Iop): Kimihia te uara iahiko e rite ana.
Tātaihia te ōwehenga whai hua o te pūngao (COP): Ngāna kia whakahaerehia te waeine hiko wera i te rohe me te COP teitei ake (tata ki te 30%-50% o te iahiko mōrahi), kaua e whakahaere i te kaha katoa. Mā te whakahaere i te kaha katoa ka tere ake te whakamatao, engari ka nui rawa te wera ka puta, ā, he iti rawa te whai huatanga.
Hipanga 4: Hanganga me te Tāutanga
He pakarukaru ake ngā kōwae whakamatao hiko maha-wāhanga (kōwae TEC maha-wāhanga) i ngā kōwae whakamatao hiko kotahi-wāhanga (kōwae peltier kotahi-wāhanga). I te wā e whiriwhiri ana i te momo, me whai whakaaro ki te hanganga ā-tinana:
Ngā Herenga Rahi:
Kāore i te tūtohutia kia nui rawa ngā kōwae whakamatao peltier maha-wāhanga (pērā i te nui atu i te 62x62mm), nā te mea ka ngāwari te piko, te pakaru rānei o ngā pereti uku ina nui rawa te wāhi. Mō te whakamatao papa-rahi, e taunakitia ana kia whakamahia ngā kōwae peltier iti maha e honoa ana i te taha whakarara, i te taha raupapa rānei.
Tikanga hononga:
Hononga raupapa: E taunakitia ana. He rite tonu te iahiko, he ngāwari ki te whakahaere. Mena ka pakaru tetahi wahi, ka taea te kite ngāwari (mā te whati i te ara iahiko).
Hononga whakarara: Kāore i te tūtohutia. Mēnā ka rerekē te ātete ā-roto o te wahi kotahi, ka kore e taurite te tohatoha o te iahiko, ka hua ake te āhuatanga "whakataetae o nāianei", ka tere ake te kino.
