Ko te waeine whakahaere hau (AHU) te hauhautanga arumoni nui rawa atu, tino ritenga hoki, ā, kei runga i te tuanui, i te pakitara rānei o te whare. He huinga tēnei o ētahi taputapu kua katihia ki te āhua o te poraka āhua-pouaka, e whakamahia ana mō te horoi, te whakamatao hau, te whakahou rānei i te hau i roto i te whare. I roto i te poto, ka whakahaere ngā waeine whakahaere hau (te pāmahana me te haumākū) i te āhua wera o te hau, me te ma o tōna tātari, ā, ka mahia e rātou mā te tohatoha i te hau mā roto i ngā paipa e toro atu ana ki ia rūma o tō whare. Kāore i rite ki ngā hauhautanga noa, ka hangaia ngā ahu hvac kia rite ki ngā whare takitahi, me te tāpiri i ngā tātari o roto, ngā whakamakuku, me ētahi atu taputapu hei whakahaere i te paerewa o te hau me te whakamarie i roto.

Ngā mahi matua o tētahi AHU

Ko ngā pūnaha whakamahana, hauhautanga, me te hauhautanga (HVAC Ahumahi Arumoni) te pūtake o ngā miihini hou, me whakamahi i te hauhautanga me te kounga hau tino pai i roto i ngā whare nunui. Ko ngā ahu i roto i te hvac ka whakanohoia ki runga i te tuanui, i te pakitara rānei o waho, ā, ka tohatohahia te hau hauhautanga mā roto i ngā paipa ki ngā rūma rerekē. Kua hangaia ēnei pūnaha mō ngā whakaritenga motuhake o te whare, me whakamatao, me whakamahana, me whakapūhautanga rānei.

He mea nui ngā waeine whakahaere hau HVAC mō te horoi i te hau me te whakahaere i te taumata CO2 i roto i ngā wāhi e nui ana te haere o te tangata pērā i ngā toa hokohoko, ngā whare tapere, me ngā whare hui. Ka kukume mai i te hau hou, ā, ka āwhina ki te whakaiti i te maha o ngā pā hau e hiahiatia ana — he rua-whakawhiti hei penapena i ngā utu pūngao me te whakatutuki i ngā whakaritenga mō te kounga o te hau. Ko ngā taiao nui, pērā i ngā rūma ma, ngā whare pokanga, me ētahi atu, ehara i te mea me whakahaere noa i te pāmahana, engari me whakahaere hoki i te akuaku nui e āwhinahia ana mā roto i ngā waeine whakahaere hau hou motuhake. Waihoki, ka tiakina e ngā pūnaha whakahaere hau ātete-pahūtanga mai i ngā pahūtanga hau mō ngā whare e whakahaere ana i ngā hau mura.

He aha ngā mea kei roto i te AHU?

Ⅰ. Whakaurunga Hau: he waeine whakahaere hau ritenga e tango ana i te hau o waho, e tātari ana, e whakatikatika ana, e tohatoha ana i roto i te whare, e tohatoha ana rānei i te hau o roto ina tika.

2. Ngā Tātari Hau: He tātari ā-ringa ēnei ka taea te tango i ngā poke o te hau — te puehu, te hae, tae atu ki ngā huakita. I roto i ngā kīhini, i ngā awheawhe rānei, ka taea e ngā tātari motuhake te āwhina ki te whakahaere i ngā tūponotanga motuhake, te whakatairanga i te hau ma me te aukati i te kohikohinga o ngā kai i roto i te pūnaha.

Ⅲ. Pā hau: Ko te wāhanga tino nui o te waeine whakahaere hau HVAC ko te pā hau, e tuku ana i te hau ki roto i ngā paipa. Te kōwhiringa o te pā hau mā te momo tae atu ki ngā pā hau piko-mua, piko-muri me ngā pā hau-hau e ai ki te pēhanga pumau me ngā hiahia hau.

Ⅳ. Whakawhiti Wera: Ka whakamahia te whakawhiti wera hei tuku i ngā taunekeneke wera i waenga i te hau me te wai whakamatao, hei āwhina hoki i te kawe i te hau ki te pāmahana e hiahiatia ana.

Ⅴ. Koiri Whakamatao: Ka whakahekehia e ngā koiri whakamatao te pāmahana o te hau e rere ana mā te whakamahi i ngā pata wai e kohia ana i roto i te paepae waiwhakamātao.

Ⅵ. ERS: Ka āwhina hoki te Pūnaha Whakaora Pūngao (ERS) ki te whakapai ake i te whai huatanga o te pūngao mā te whakawhiti i te pūngao wera i waenga i te hau i tangohia me te hau o waho, ka whakaiti i te hiahia whakamahana, whakamatao rānei tāpiri.

Ⅶ. Ngā Wāhanga Whakamahana: Hei whakahaere i te pāmahana, ka taea te whakauru i ngā wāhanga whakamahana, tae atu ki ngā whakamahana hiko, ngā whakawhiti wera rānei, ki roto i te AHU.

Ⅷ. Kaiwhakamakuku/Whakakore-Whakamakuku: He taputapu ēnei hei whakahaere i te makuku o te hau mō ngā āhuatanga pai o roto.

Ⅸ. Te Wāhanga Whakaranu: Mā tēnei ka taurite te ranunga o te hau o roto me te hau o waho, kia tika ai te pāmahana me te kounga o te hau e tukuna ana kia whakamataohia, ā, kia iti rawa te pūngao e pau ana.

Ⅹ. Take: Ngā Kaiwhakangāwari: Ka whakaiti i te haruru kia noho pai ai te taiao nā te mea ka puta te haruru i te wā e whakahaerehia ana ngā pā hau me ētahi atu wāhanga.

Te whai huatanga o te pūngao o ngā AHU

Ko te whai huatanga o te pūngao (mai i te tau 2016, he whakaritenga i raro i te Ture Whakatakoto Ahuahanga Pākehā 1235/2014) he āhuatanga nui o tētahi waeine whakahaere hau (AHU). Ka pērā mā ngā waeine whakaora wera e whakaranu ana i te hau o roto me te hau o waho, ka tata ake te rerekētanga pāmahana, ka penapena i te pūngao mō te hauhautanga. He mana whakahaere rerekē ngā pā, ka taea ai e rātou te whakarerekē i ngā whakaritenga rere hau e hiahiatia ana, ka taea ai e te waeine whakahaere hau hvac te whai hua ake, ā, ka iti ake te hiahia ki te pūngao.
