Te pāmahana i roto ite pokepokea ai werohangahe kore taurite i ngā wāhi rerekē, e pā ana hoki ki te wā i roto i te huringa werohanga. Ko te mahi a te mīhini pāmahana pokepokea ai he pupuri i te pāmahana kia mau tonu i waenga i te 2min me te 2max, ko te tikanga he ārai i te rerekētanga pāmahana mai i te piki me te heke i te wā o te tukanga whakaputa, i te āputa rānei. He pai ngā tikanga whakahaere e whai ake nei mō te whakahaere i te pāmahana o te pokepokea ai: Ko te whakahaere i te pāmahana o te wai te tikanga e whakamahia whānuitia ana, ā, ka taea e te tika o te whakahaere te whakatutuki i ngā whakaritenga o te nuinga o ngā āhuatanga. Mā te whakamahi i tēnei tikanga whakahaere, kāore te pāmahana e whakaaturia ana i runga i te kaiwhakahaere e rite ana ki te pāmahana o te pokepokea ai; he nui te rerekētanga o te pāmahana o te pokepokea ai, nā te mea kāore anō kia inehia tika, kia utua rānei ngā āhuatanga wera e pā ana ki te pokepokea ai mō ēnei āhuatanga tae atu ki ngā huringa o te huringa werohanga, te tere werohanga, te pāmahana rewa me te pāmahana rūma. Ko te tuarua ko te whakahaere tika i te pāmahana pokepokea ai. Ko tēnei tikanga he tāuta i tētahi pūoko pāmahana ki roto i te pokepokea ai, ka whakamahia anake ina he teitei te tika o te whakahaere pāmahana pokepokea ai. Ko ngā āhuatanga matua o te whakahaere pāmahana pokepokea ai ko: ko te pāmahana i whakatakotoria e te kaiwhakahaere e rite ana ki te pāmahana o te pokepokea ai; ka taea te ine tika me te utu i ngā āhuatanga wera e pā ana ki te pokepokea ai. I raro i ngā āhuatanga noa, he pai ake te pumau o te pāmahana pokepokea ai i te whakahaere i te pāmahana wai. Hei tāpiri, he pai ake te auau o te whakahaere pāmahana pokepokea ai i roto i te whakahaere tukanga whakaputa. Ko te tuatoru ko te whakahaere hononga. Ko te whakahaere hononga he whakakotahitanga o ngā tikanga o runga ake nei, ka taea te whakahaere i te pāmahana o te wai me te pokepokea ai i te wā kotahi. I roto i te whakahaere hononga, he mea tino nui te tūranga o te pūoko pāmahana i roto i te pokepokea ai. I te wā e whakanoho ana i te pūoko pāmahana, me whai whakaaro ki te āhua, te hanganga, me te wāhi o te awa whakamatao. Hei tāpiri, me whakanoho te pūoko pāmahana ki tētahi wāhi e whai wāhi nui ana ki te kounga o ngā wāhanga i werohia. He maha ngā huarahi hei hono i tētahi, neke atu rānei o ngā mīhini pāmahana pokepokea ai ki te kaiwhakahaere mīhini werohia. He pai ake te whakamahi i tētahi atanga matihiko e pā ana ki te whakahaere, te pono me te ārai-whakararuraru.

Ko te taurite wera ote pokepokea ai werohangaKo te whakahaere i te kawe wera i waenga i te mīhini whakarewa werohanga me te pokepokea ai te mea nui ki te hanga i ngā wāhanga whakarewa werohanga. I roto i te pokepokea ai, ka whakawhitia te wera e kawea mai ana e te kirihou (pērā i te thermoplastic) ki te rauemi me te maitai o te pokepokea ai mā te hihi wera, ā, ka whakawhitia ki te wai whakawhiti wera mā te convection. Hei tāpiri, ka whakawhitia te wera ki te āhuarangi me te turanga pokepokea ai mā te hihi wera. Ka tangohia te wera e mimitia ana e te wai whakawhiti wera e te mīhini pāmahana pokepokea ai. Ka taea te whakaahua i te taurite wera o te pokepokea ai penei: P=Pm-Ps. Ko P te wera e tangohia ana e te mīhini pāmahana pokepokea ai; Ko Pm te wera e kawea mai ana e te kirihou; Ko Ps te wera e tukuna ana e te pokepokea ai ki te āhuarangi. Ko te kaupapa o te whakahaere i te pāmahana pokepokea ai me te awe o te pāmahana pokepokea ai ki ngā wāhanga whakarewa werohanga I roto i te tukanga whakarewa werohanga, ko te kaupapa matua o te whakahaere i te pāmahana pokepokea ai ko te whakamahana i te pokepokea ai ki te pāmahana mahi, me te pupuri i te pāmahana pokepokea ai kia mau tonu i te pāmahana mahi. Mena ka angitu ngā tohu e rua i runga ake nei, ka taea te arotau i te wā huringa kia mau ai te kounga teitei o ngā wāhanga whakarewa werohanga. Ka pā te pāmahana pokepokea ai ki te kounga o te mata, te rere, te mimiti, te huringa werohanga me te whakarerekētanga. Ka rerekē ngā pānga o te pāmahana pokepokea ai ki ngā rauemi rerekē mēnā he nui rawa, he kore rānei e ranea. Mō ngā kirihou wera, ka whakapai ake te pāmahana pokepokea ai i te kounga me te rere o te mata, engari ka roa ake te wā whakamatao me te huringa werohanga. Ka whakaitihia e te pāmahana pokepokea ai iti ake te mimiti i roto i te pokepokea ai, engari ka whakanuia ake te mimiti o te wāhanga i werohangahia i muri i te tangohanga. Mō ngā kirihou wera, ka whakaitihia e te pāmahana pokepokea ai teitei ake te wā huringa, ā, ka whakatauhia te wā e hiahiatia ana kia whakamatao te wāhanga. Hei tāpiri, i roto i te tukatuka kirihou, ka whakaitihia hoki e te pāmahana pokepokea ai teitei ake te wā whakakirihou me te whakaiti i te maha o ngā huringa.
