Me pehea te tatau e hiawhakamatao rangi ahumahie hiahiatia ana i roto i te awheawhe. Na te whakawhanaketanga o te hangarau whakamatao hau-a-taiao, ka nui ake nga wheketere me nga awheawhe ka whiriwhiri hei taputapu whakamahana mo a raatau kaimahi. He maha nga tangata e kii ana e hia nga umanga whakamahana hau e hiahiatia ana, patai noa ki tetahi kaihoko ngaio, ki tetahi tohunga hangarau whakamahana rangi ahumahi ranei. Inaa, i mua i tenei, ka taea hoki e koe te ako ki te tatau e hiawhakamatao rangi ahumahie hiahia ana koe i roto i to whare ake.

Tuatahi, ka taea e tatou te tatau i runga i te ariā. Ko te tikanga tatauranga ko te tatau tuatahi i te taumaha whakamahana, te uta makuku me te rahinga o te hau o te waahi kua whakamahia kia rite ki te tikanga tataitanga o te hau whakamahana o te hau, katahi ka tatauhia te katoa o te kaha whakamahana ka taea e te umanga hau makariri te whakarato, kia pai ai te whiriwhiri. tiaki pūngao me te tiaki taiao. Mo te maha me te tauira o te whakamahana hau, te katoa o te kaha whakamahana owhakamatao rangi ahumahime nui ake i te kaha whakamahana e hiahiatia ana e te waahi whakamahi, a ko te toenga o te kaha ka kiia ko te 10%.

Te tātaitanga ariā o te katoa o te kaha whakamahana owhakamatao rangi ahumahi:

Tapeke kaha whakamahana S=LρCp{e•(tg-ts)+tn-tg}/3600

i roto i:

L——Ko te nui o te tukunga o te hau mo te penapena hiko me te whakamatao o te hau (m3/h)

Ρ——Te kiato o te hau i te putanga (kg/m3)

Cp——Te wera motuhake o te hau (kJ/kg•K)

E——Ko te whaihua o te whakamaarama hau o te umanga, te tikanga 85%

(Tg-ts)——He rereke te pāmahana o te umanga maroke me te makuku (℃)

(Tn-tg)——He rerekee i waenga i roto me waho (℃)

Whakatakotoria te △t1=(tg-ts), △t2=(tn-tg), ko te △t1 he uara takatika, me te △t2 he uara pai me te kino.

Ko te katoa o te kaha whakamahana S=LρCp(e•△t1+△t2), kei reira te ρ, Cp, e he pūmau. Ka taea te kite ko te katoa o te kaha whakamahana o te umanga hau makariri me te whakaputanga o te hau o te hau makariri, te rereketanga i waenga i te wera maroke me te makuku, Ko te rereketanga o te pāmahana i waenga i roto me waho e pa ana. I te mea ko te △t1 me te △t2 he rahinga koretake, ka huri i te huringa o te pāmahana taiao o waho, no reira ko te tikanga o te katoa o te kaha whakamahana ka whakamahia noa mo te tātaritanga kounga, he iti noa te whakamahi mo te tatau ine.

Tuarua, ka whakamahia e matou o maatau wheako ki te tatau i te maha o nga taputapu i runga i nga ahuatanga o XIKOOwhakamatao rangi ahumahi. Arā, ko te maha o nga huringa hau ka whakamahia hei tawhā ki te whakatau i te maha o te whakamatao rangi ahumahi e hiahiatia ana i tetahi waahi. He tikanga hoahoa e whakamahia nuitia ana mo te whakamatao rangi ahumahi.
