Te māramatangaPā HVLS (Teitei te Rōrahi Tere Iti)He mea nui ngā whakaritenga hei whakatau i te pā hau e tika ana mō ō hiahia. Anei ngā āhuatanga matua hei whakaaroaro:
Rahi o te Pā:Kei te wātea ngā pā hau HVLS i ngā rahi rerekē, mai i te 8 ki te 24 putu te whānui. Mā te rahi o te pā hau e whakatau tōna horahanga taupoki me te kaha o te hau e rere.
Te kaha o te rere o te hau:Ko te tikanga ka inehia tēnei i roto i ngā putu kūpiko ia meneti (CFM) me ngā mita kūpiko ia hāora (m3/h). E tohu ana tēnei i te nui o te hau ka taea e te pā hau te neke i roto i tētahi wā kua whakaritea, ā, he mea nui kia taurite te kaha o te hau o te pā hau ki te rahi o te wāhi e whakamahia ai.

Mana Mōta:Ko te mana o te motuka, e inehia ana i roto i te hōpaika (HP) me te watts (W), e tohu ana i te whakapaunga pūngao me te kaha o te pā hau ki te whakaputa hau. Ko te mana motuka teitei ake e hono ana ki te kaha hau nui ake.
Teitei Whakamaunga:Ko ētahi o ngā whakatakotoranga o te pā hau ko te teitei whakairinga kua tūtohutia, arā, te tawhiti i waenga i te pā hau me te papa. He mea nui tēnei kia pai ai te rere o te hau me te mahi tino pai.
Taumata Haruru: Pā HVLSKei roto pea i ngā whakatakotoranga te taumata haruru, e inehia ana i roto i ngā desipela (dB). Ko te dB iti iho e tohu ana i te mahi mārire ake, he mea nui pea tēnei mō ngā taiao e āwangawanga ana mō ngā taumata haruru.
Ngā Mana Whakahaere me ngā Āhuatanga:Rapua ngā mōhiohio mō ngā āhuatanga tāpiri, pērā i te whakahaere tere whakarerekē, te mahi whakamuri, me ngā kōwhiringa whakahaere atamai.
Ka taea e ēnei te whakarei ake i te maha o ngā whakamahinga me te whai huatanga o te pā hau. Mā te mārama ki ēnei whakaritenga ka āwhina i a koe ki te whiriwhiri i te pā hau HVLS tika mō tō tono motuhake, ā, ka whakarite kia puta te rere o te hau me ngā painga whakamatao e hiahiatia ana.
