Kei te huri tonu te āhua o te papatohu pokapū o te motuka, ā, kei te auaha tonu, engari kāore anō kia rerekē te wāhi whakahaere hauhautanga, ahakoa kei te whakanoho tika ētahi tauira i te mana whakahaere hauhautanga ki te mata pokapū, engari ko te kī tonu te mea matua, kātahi ka whakamāramahia e mātou te mahi matua o te hauhautanga o te motuka.
E toru ngā whakarerekētanga taketake o te hauhautanga waka, arā, te rahinga o te hau, te pāmahana me te ahunga o te hau. Ko te tuatahi ko te pātene rahinga o te hau, e mōhiotia ana ko te pātene tere o te hau, ko te ata he "pā" iti, mā te huri i te pātene hei whiriwhiri i te rahinga o te hau e tika ana.
Ko te kī pāmahana e whakaatuhia ana i te nuinga o te wā hei "inemahana", he tohu tae whero me te kikorangi rānei kei ngā taha e rua. Mā te huri i te porowhita, ka piki haere te pāmahana i te wāhi whero; i tetahi atu taha, ka heke haere te pāmahana i te kikorangi.
Ko te whakarerekētanga o te ahunga hau he pātene pēhi, he porotiti rānei, engari he tika ake, he kitea hoki, mā te ata "tangata e noho ana me te pere ahunga hau", e whakaaturia ana i te pikitia, ka taea te whiriwhiri ki te pupuhi i te upoko, pupuhi i te upoko me te waewae, pupuhi i te waewae, pupuhi i te waewae me te matapihi, pupuhi rānei i te matapihi anake. Tata ki te katoa o ngā whakarerekētanga o te ahunga hau o te hauhautanga waka he pērā, he iti noa iho ngā rerekētanga.
Haunga ngā whakarerekētanga taketake e toru, kei reira ētahi atu pātene, pērā i te pātene A/C, arā, te pana whakamatao. Pēhia te pātene A/C, ka tīmata anō hoki te compressor, arā, te huri i te hau matao.
Kei reira anō te pātene Huringa o Roto o te motuka, he ata e kī ana "He pere hurihanga kei roto i te motuka." Mena kua tahuri te hurihanga o roto, ko te tikanga ka huri noa te hau mai i te pupuhi i roto i te motuka, he rite ki te pupuhi i te pā hiko me te kuaha kua kati. Nā te mea kāore he hau o waho e uru ana, he painga te hurihanga o roto o te penapena hinu me te whakamatao tere. Engari mō tēnei take tonu, kāore te hau i roto i te motuka e whakahoutia ana.
Me te pātene huringa o roto, he pono, kei reira he pātene huringa o waho, he tohu "waka, i waho o te pere ki roto", ko te tikanga, ko te hauhautanga o te waka ko te huringa o waho, nō reira kāore i ētahi tauira tēnei pātene. Ko te rerekētanga i waenganui i a rātou ko te tohanga o waho ko te pupuhi e hongi ana i te hau mai i waho o te waka ka pupuhi ki roto i te waka, ka taea te pupuri i te hou o te hau i roto i te waka (ina koa ko te wāhi e pai ana te hau i waho o te waka).
