Aratohu Kōwhiri Tauira mō te Whare Noho
Kōwhiringa o te rere o te hau:
Tuatahi, ko te kōwhiringa o te rōrahi hau e pā ana ki te whakamahinga o te papaanga, te kiato o te taupori, te hanganga o te whare, me ētahi atu.
Hei tauira, whakamāramahia me te noho kāinga anake ināianei:
Tikanga tātai 1:
He whare noho noa, he 85 mita te rahi o roto, e toru ngā tāngata e noho ana.
| Rohe noho mō ia tangata - Fp | Ngā huringa hau i ia hāora |
| Fp≤10㎡ | 0.7 |
| 10㎡＜Fp≤20㎡ | 0.6 |
| 20㎡＜Fp≤50㎡ | 0.5 |
| Fp>50㎡ | 0.45 |
Tirohia te Waehere Hoahoa mō te Whakamahana, te Whakahauhautanga me te Whakamātao i ngā Whare Ā-iwi (GB 50736-2012) hei tatau i te nui o te hau hou. Kei roto i te whakatakotoranga te nui iti rawa o te paipa hau hou (arā, te whakaritenga "iti rawa" me tutuki). E ai ki te ripanga i runga ake nei, kaua e iti iho i te 0.5 ngā wā whakawhiti hau /h. Ko te rohe whakahauhautanga whai hua o te whare he 85㎡, ko te teitei he 3M. Ko te nui iti rawa o te hau hou ko 85×2.85 (teitei kupenga) ×0.5=121m³/h. I te wā e whiriwhiri ana i ngā taputapu, me tāpiri hoki te nui turuturu o ngā taputapu me te paipa hau, me tāpiri hoki te 5%-10% ki te pūnaha tuku hau me te pūnaha whakaputa hau. Nō reira, kaua e iti iho i te: 121× (1+10%) =133m³/h. I roto i te ariā, me whiriwhiri te 150m³/h kia tutuki ai ngā whakaritenga iti rawa.
Kotahi te mea hei mōhio, mō te whiriwhiri taputapu whare noho e taunakitia ana kia neke atu i te 0.7 ngā wā whakawhiti hau; ko te rahinga hau o ngā taputapu ko: 85 x 2.85 (teitei kupenga) x 0.7 x 1.1 = 186.5m³/h, E ai ki te tauira taputapu o nāianei, me whiriwhiri e te whare he taputapu hau hou 200m³/h! Me whakarite ngā paipa kia rite ki te rahinga hau.
