Ina tae ki ngā wāhi ahumahi nui,Ngā pā hau tere iti (HVLS)he whiringa rongonui mō te whakarato i te tohanga hau me te whakamatao pai. Ko tētahi o ngā mea matua hei whakatau i te whai huatanga o tētahi pā hau HVLS ko tōna whakatauranga CFM (Cubic Feet per Minute), e ine ana i te nui o te hau ka taea e te pā hau te neke i roto i te meneti. He mea nui te mārama ki te tatau i te CFM o tētahi pā hau HVLS kia tika ai te rahi mō te wāhi e whakaarohia ana hei mahi māna.

Hei tatau i te CFM o te pā HVLS, ka taea e koe te whakamahi i te tātai:CFM = (Horahanga o te wāhi x Huringa Hau ia Hāora) / 60. Te rohe o te wāhiko te tapeke o ngā putu tapawha o te rohe ka tukuna e te pā hau, ā,te whakawhiti hau i ia haorako te maha o ngā wā e hiahia ana koe kia whakakapia katoatia te hau i roto i taua wāhi ki te hau hou i roto i te haora. Kia whiwhi koe i ēnei uara, ka taea e koe te whakauru i ēnei ki te tātai hei whakatau i te CFM e hiahiatia ana mō te wāhi.

TĀTAIA TE CFM O TE PĀ

Ina tae ki te Apogee CFM, e pā ana ki te CFM mōrahi ka taea e te pā hau HVLS te whakatutuki i tana tautuhinga tere teitei rawa atu. He mea nui tēnei uara hei mārama ki ngā kaha o te pā hau, me te whakatau mēnā ka taea e ia te whakatutuki i ngā hiahia hauhautanga me te whakamatao o tētahi wāhi motuhake. He mea nui kia whakaarohia te Apogee CFM i te wā e whiriwhiri ana i tētahi pā hau HVLS kia tino taea ai e ia te tuku i te hau e hiahiatia ana mō te tono e whakaarohia ana.

Haunga te tātai mō te tatau i te CFM, he mea nui anō hoki kia whakaarohia ētahi atu āhuatanga ka taeapā ki te mahio tētahi pā HVLS, pērā ite hoahoa o te mata o te pā, te whai huatanga o te mōtini, me te tahora o te wāhi.Ka pā anō hoki te tāutanga me te tūnga tika o te pā hau ki tōna kaha ki te neke i te hau puta noa i te wāhi.

Hei whakamutunga, kia mārama ki te tatau i teCFM o te pā HVLShe mea nui kia tika te rahi mō te tono e whakaarohia ana.Mā te whakaaro ki te Apogee CFM me ētahi atu mea ka pā ki te mahi a te pā hau, ka āwhina i te whiriwhiri i te pā hau HVLS tika mō te tohanga o te hau me te whakamatao pai rawa atu i ngā wāhi ahumahi nunui.
