1. Te Whakataki i ngā Wāhanga Whakamatao Whakarara
Ko te waeine whakarara e pā ana ki tētahi waeine whakamatao e whakauru ana i ngā pūwero neke atu i te rua ki roto i te whatanga kotahi, ā, e mahi ana ki ngā pūwero maha. He rite te pēhanga mimiti me te pēhanga haukū o ngā pūwero, ā, ka taea e te waeine whakarara te whakarite aunoa i te pūngao kia rite ki te kawenga o te pūnaha. Ka taea e ia te whakatutuki i te kakahu ōrite o te pūwero, ā, he iti te wāhi e nohoia ana e te waeine whakamatao, ā, he ngāwari ki te whakatinana i te mana whakahaere pokapū me te mana mamao.
Ka taea te tito i te huinga waeine kotahi mai i te momo pūwero kotahi, i ngā momo pūwero rerekē rānei. Ka taea te tito i te momo pūwero kotahi (pēnei i te mīhini piston), ka taea rānei te tito i ngā momo pūwero rerekē (pēnei i te mīhini piston + mīhini tīwiri); ka taea te uta i te pāmahana mimiti kotahi, i ētahi pāmahana mimiti rerekē rānei. Te pāmahana; ka taea te pūnaha kotahi-wāhanga, te pūnaha rua-wāhanga rānei; ka taea te pūnaha kotahi-huringa, te pūnaha hūkere rānei, me ētahi atu. Ko te nuinga o ngā pūwero noa he pūnaha kotahi-huringa whakarara o te momo kotahi.
He pai ake te ōrite o ngā waeine pūwero whakarara ki te kawenga whakamatao hihiri o te pūnaha whakamatao. Mā te whakarerekē i te tīmatanga me te whakamutu o te pūwero i roto i te pūnaha katoa, ka karohia te āhuatanga o te "hōiho nui me te kāreti iti". Hei tauira, ina iti te tono kaha whakamatao i te takurua, ka iti ake te tahuri o te pūwero, ā, i te raumati, ka nui ake te tono kaha whakamatao, ā, ka nui ake te tahuri o te pūwero. Ka noho pumau te pēhanga momi o te waeine pūwero, ka tino whakapai ake i te whai huatanga o te pūnaha. Kua oti he whakamātautau whakatairite i te waeine kotahi me te waeine whakarara i runga i te pūnaha kotahi, ā, ka taea e te pūnaha waeine whakarara te penapena pūngao mā te 18%.
Ka taea te whakaemi i ngā mana whakahaere katoa mō ngā pūwero, ngā pūwhakamātao me ngā pūwhakamomona ki roto i te pouaka whakahaere hiko o te pūnaha, ā, ka taea hoki te whakamahi i ngā mana whakahaere rorohiko hei whakanui ake i te whai huatanga o te pūnaha. Ko te tikanga, ka taea te whakatutuki i te mahi katoa a te tangata kore-kaimahi me te mahi mamao.
2. Te ahunga o te paipa me te kōwhiringa o te diameter o te paipa
Te ahunga o te paipa: I roto i te pūnaha whakamatao Freon, ka rere tahi te hinu whakahinuhinu o te pūwero i roto i te pūnaha me te hau whakamatao, nō reira, kia pai ai te hokinga mai o te hinu o te pūnaha, me whai pari te paipa hau whakahoki (paipa pēhanga iti) ki te pūwero, ko te nuinga he pari o te 0.5%.
Kōwhiringa diameter o te paipa: Mena he iti rawa te diameter o te paipa parahi, ka nui rawa te ngaronga pehanga o te refrigerant i roto i te paipa tuku wai (paipa pēhanga teitei) me te paipa hau whakahoki (paipa pēhanga iti); Mena he nui rawa te uara, ahakoa ka taea te whakaiti i te ngaronga ātete i roto i te paipa, ka piki ake te utu haumi tuatahi, ā, i te wa ano, ka kore e ranea te tere hoki mai o te hinu i roto i te paipa hau whakahoki.
Te mātāpono whiriwhiri i te whānui o te paipa e whakaarohia ana: ko te tere rere o te hau whakamatao i roto i te paipa tuku wai he 0.5-1.0m/s, kaua e neke atu i te 1.5m/s; i roto i te paipa hau whakahoki, ko te tere rere o te hau whakamatao i roto i te paipa whakapae he 7-10m/s, ko te tere rere o te hau whakamatao i roto i te paipa piki he 15~18m/s.
Hoahoa momo peka: Kei te waeine whakarara ngā pane tuku wai me ngā pane hau whakahoki, ā, he maha ngā peka tuku wai kei te pane tuku wai, ā, kotahi te peka hau whakahoki e rite ana ki ia peka tuku wai ka kohia ki roto i te pane hau whakahoki. I te pane hau whakahoki, ka kiia tēnei paipa pūnaha whakamatao waeine whakarara he momo peka. Ka taea e ia takirua peka, arā, he peka tuku wai me tōna peka whakahoki hau e rite ana, te whai i tētahi kaiwhakaoho kotahi (peka 1) he rōpū kaiwhakaoho rānei (peka n). Ina he rōpū kaiwhakaoho, ko te tikanga ka tīmata, ka mutu te rōpū kaiwhakaoho i te wā kotahi.
He teitei ake te pūwhakapūngao i te pūwhakapūngao:
Mena he teitei ake te pūwhakamahana i te pūwhakamātao, mena he pari te rārangi whakahoki, ā, he pai te diameter o te paipa e whiriwhiria ana, ka taea e te pūnaha te whakarite kia maeneene te hokinga mai o te hinu. Heoi, ki te nui rawa te rerekētanga teitei i waenga i te pūwhakamahana me te pūwhakamātao, ka puta he mamaoa tere mai i te wai whakamatao i roto i te paipa tuku wai i mua i te taenga ki te tikanga whakamātao.
He iti iho te pūwhakapūngao i te pūwhakapūngao:
Mena kei raro iho te pūwero i te pūwero, e kore te hauhautanga i roto i te paipa tuku wai e whakaputa i te mamaoa tere nā te rerekētanga teitei i waenga i te pūwero me te pūwero, engari i te wā e hoahoa ana i te paipa pūnaha whakamatao, me tino whai whakaaro ki te hokinga mai o te pūnaha. Mō te raruraru hinu, i tēnei wā, me hoahoa me te tāuta te piko hokinga mai o te hinu ki te wāhanga piki o ia peka hau hokinga.
He teitei ake te pūwhakapūngao i te pūwhakapūngao:
Mena he teitei ake te pūwhakamahana i te pūwhakamātao, mena he pari te rārangi whakahoki, ā, he pai te diameter o te paipa e whiriwhiria ana, ka taea e te pūnaha te whakarite kia maeneene te hokinga mai o te hinu. Heoi, ki te nui rawa te rerekētanga teitei i waenga i te pūwhakamahana me te pūwhakamātao, ka puta he mamaoa tere mai i te wai whakamatao i roto i te paipa tuku wai i mua i te taenga ki te tikanga whakamātao.
He iti iho te pūwhakapūngao i te pūwhakapūngao:
Mena kei raro iho te pūwero i te pūwero, e kore te hauhautanga i roto i te paipa tuku wai e whakaputa i te mamaoa tere nā te rerekētanga teitei i waenga i te pūwero me te pūwero, engari i te wā e hoahoa ana i te paipa pūnaha whakamatao, me tino whai whakaaro ki te hokinga mai o te pūnaha. Mō te raruraru hinu, i tēnei wā, me hoahoa me te tāuta te piko hokinga mai o te hinu ki te wāhanga piki o ia peka hau hokinga.
