He maha ngā tikanga whakamatao, ā, ko ēnei e whakamahia whānuitia ana:
1. Te whakamatao i te mimiti wai
2. Te whakawhānui me te whakamatao hau
3. Te whakamatao ngongo awhiowhio
4. Whakamatao hiko wera
I roto i ēnei, ko te whakamatao mimiti wai te mea e whakamahia whānuitia ana. Ka whakamahia te pānga mimiti wera o te mimiti wai hei whakatutuki i te whakamatao. Ko te pēhi mimiti, te mimiti, te weronga mimiti me te whakamatao mimiti he whakamatao mimiti wai katoa.
Ko te whakamatao pēhanga kohu he momo whakamatao huringa āhuahanga, e whakamahi ana i te pānga mimiti wera ina huri te hauhautanga mai i te wai ki te hau hei whiwhi i te pūngao makariri. E whā ngā wāhanga o tēnei: te pūwhakakoi, te pūwhakamātao, te pūnaha whakawhāiti me te pūwhakamomona. Ka honoa ēnei e ngā paipa hei hanga i tētahi pūnaha kati.
Ngā wāhanga matua o te pouaka whakamātao me ngā taputapu tāpiri
1. Pūhiko
E toru ngā hanganga o ngā pūwhakakoi: te momo tuwhera, te momo tuwhera-haurua, me te momo kati. Ko te mahi a te pūwhakakoi he mimiti i te hauhautanga pāmahana-iti mai i te taha whakapūhau, ka pēhi hei kohu hauhautanga pēhanga-teitei, pāmahana-teitei, ka tukuna ki te pūwhakakoi.
2.Whakamātao
Ko te pūwhakamātao he taputapu whakawhiti wera e whakawhiti ana i te kaha whakamatao o te pūwhakamātao i roto i te pūnaha whakamatao me te mahi tohu pēhanga o te pūwhakamātao ki te reo taiao (wai whakamatao, hau rānei). E ai ki te tikanga whakamatao, ka taea te wehewehe i te pūwhakamātao ki te hau whakamatao, te wai whakamatao me te mimiti. Ko te pūwhakamātao he taputapu whakawhiti wera e whakawhiti ana i te kaha whakamatao o te pūwhakamātao i roto i te pūnaha whakamatao me te mahi tohu pēhanga o te pūwhakamātao ki te reo taiao (wai whakamatao, hau rānei). E ai ki te tikanga whakamatao, ka taea te wehewehe i te pūwhakamātao ki te hau whakamatao, te wai whakamatao me te mimiti.
3. Pūwhakapūhau
Ko te tikanga o te whakapūhaumāota he kohua te wai hauhautanga, ā, ka mimiti i te wera o te reo kua whakamataotia (te hau, te wai rānei) i te pāmahana iti iho hei whakatutuki i te kaupapa o te whakamatao.
4. takirere solenoid
Ko te takirere solenoid he momo takirere kati e tuwhera aunoa ana i raro i te mana hiko. He mea tāuta ki runga i te paipa pūnaha hei whakakā me te whakaweto aunoa i te kaiwhakahaere o te pūnaha whakamātao e rua ngā tūranga. Ko te takirere solenoid he mea tāuta ki waenganui i te takirere whānui me te pūwhakamātao. Me tata rawa te wāhi ki te takirere whānui, nā te mea he wāhanga whakatere noa iho te takirere whānui, kāore e taea te kati ko ia anake, nō reira me whakamahi he takirere solenoid hei tapahi i te paipa tuku wai.
5. Takirere whakawhanui wera
He maha ngā wā ka whakamahia e ngā taputapu whakamatao ngā takirere whakawhanui wera hei whakatika i te rere o te hauhautanga. Ehara i te mea ko te takirere whakahaere anake te mea e whakahaere ana i te tuku wai o te evaporator, engari ko te takirere whakatere hoki o te taputapu whakamatao. Ka whakamahia e te takirere whakawhanui wera te huringa o te wera nui o te hauhautanga i te putanga o te evaporator hei whakatika i te tuku wai. Ka honoa te takirere whakawhanui wera ki te paipa tomo wai o te evaporator, ā, ka whakatakotoria te pūangi aro turuki pāmahana ki runga i te paipa putanga (putanga) o te evaporator. I te nuinga o te wā ka wehea kia rerekē ngā hanganga e ai ki te hanganga o te takirere whakawhanui wera:
(1) Takirere whakawhanui wera taurite ā-roto;
(2) Te takirere whakawhanui wera taurite o waho.
Takirere whakawhanui wera ā-roto: He mea tito mai i te pūangi ine pāmahana, te ngongo kapia, te nohoanga takirere, te diaphragm, te tokotoko pana, te ngira takirere me te tikanga whakarite. Ko ngā takirere whakawhanui wera ā-roto he mea whakamahi whānuitia i roto i ngā mīhini whakapūngao iti.
Takirere whānui wera taurite o waho: Takirere whānui wera taurite o waho Mō ngā pūwero wai he roa ngā paipa, he nui ake rānei te ātete, he maha ngā wā ka whakamahia ngā takirere whānui wera taurite o waho. Mō te pūwero wai he rite te rahi, ka taea te whakamahi i te takirere whānui taurite o roto ina whakamahia i roto i te rokiroki pāmahana teitei, ko te takirere whānui taurite o waho ka taea te whakamahi i te wā ka whakamahia i roto i te rokiroki pāmahana iti. Mō te pūwero wai he rite te rahi, ka taea te whakamahi i te takirere whānui taurite o roto ina whakamahia i roto i te rokiroki pāmahana teitei, ko te takirere whānui taurite o waho ka taea te whakamahi i te wā ka whakamahia i roto i te rokiroki pāmahana iti.
6. Wehewehe hinu
I te nuinga o te wā ka tāutahia he wehewehe hinu i waenganui i te pūwero me te pūwero hei wehe i te hinu mīhini whakamatao kua mau ki roto i te kohu whakamatao. Ka whakamahia te taputapu whakahoki hinu hei whakahoki i te hinu mīhini whakamatao ki te pouaka whakakā o te pūwero; e rua ngā momo o te hanganga e whakamahia whānuitia ana o te wehewehe hinu: te momo porowhita me te momo tātari.
7. Wehewehe hau-wai
Wehea te hauhautanga hau mai i te hauhautanga wai hei ārai i te compressor mai i te hama wai; rongoatia te wai hauhautanga ki roto i te huringa pouaka whakamātao, ka whakarerekē i te tuku wai kia rite ki te huringa kawenga.
8. Puna Wai
Mā te whakatakoto i te pūhiko, ka taea te whakamahi i te kaha rokiroki wai o te pūhiko hei whakataurite me te whakau i te tohanga hauhautanga i roto i te pūnaha, kia mahi noa ai te taputapu whakamatao. Ko te tikanga, ka whakatakotoria te pūhiko i waenganui i te pūwhakamātao me te wāhanga whakawhāiti. Kia pai ai te urunga o te hauhautanga wai i roto i te pūwhakamātao ki roto i te pūhiko, me iti iho te tūranga o te pūhiko i te pūwhakamātao.
9. Whakamaroke
Hei whakarite i te rere noa o te hauhautanga, me noho ma, me noho maroke hoki te pūnaha whakamatao. I te nuinga o te wā ka tāutahia te whakamaroke tātari i mua i te wāhanga whakakā. Ina puta tuatahi te hauhautanga wai mā roto i te whakamaroke tātari, ka taea te ārai i te aukati i roto i te wāhanga whakakā.
10. Karāhe tirohanga
Ko te nuinga o te wā e whakamahia ana hei tohu i te āhua o te hauhautanga i roto i te paipa wai o te taputapu whakamatao me te nui o te wai i roto i te hauhautanga. I te nuinga o te wā, ka tohua ngā tae rerekē ki te pouaka o te karāhe tirohanga hei tohu i te nui o te wai o te hauhautanga i roto i te pūnaha.
11. Te whakawhiti hiko teitei me te iti
Ki te nui rawa te pēhanga tukunga o te pūwero, ka momotu aunoa, ka whakamutua te pūwero, ka whakakorea te pūtake o te pēhanga teitei, kātahi ka tautuhi anō ā-ringa hei tīmata i te pūwero (hapa + whakaoho); ina heke te pēhanga momi ki te rohe o raro, ka momotu aunoa. Whakamutua te pūwero, ka whakakahangia anō te pūwero ina piki te pēhanga momi ki te rohe o runga.
12. Te whakawhiti pēhanga hinu rerekē
Ko te pana hiko e whakamahi ana i te rerekētanga pēhanga i waenga i te momi me te tukunga o te papu hinu whakahinuhinu hei tohu whakahaere, ina iti iho te rerekētanga pēhanga i te uara kua whakaritea, ka mutu te compressor hei tiaki.
13. Whakapāmahana pāmahana
Whakamahia te pāmahana hei tohu whakahaere hei whakahaere i te pāmahana o te rokiroki makariri. Ka taea te whakahaere tika i te tīmatanga me te whakamutu o te pūwero mā te whakahaere i te whakakā me te whakaweto o te takirere solenoid tuku wai; ina he maha ngā peeke o te mīhini kotahi, ka taea te hono i ngā whakawhiti pāmahana o ia peeke kia rite ki te whakahaere i te tīmatanga me te whakamutu aunoa o te pūwero.
14. Pūmahana Whakamatao
Ko ngā pouaka whakamatao, e mōhiotia ana ko ngā pouaka whakamatao me ngā pouaka whakamātao, he rauemi pāpāho e whakamahia ana i roto i ngā miihini wera hei whakaoti i te huringa pūngao. Ko te tikanga, ka whakamahia e ēnei matū ngā whakawhiti āhuahanga hurihuri (pēnei i te whakawhiti āhuahanga hau-wai) hei whakanui ake i te mana.
15. Hinu whakamatao
Ko te mahi matua a te hinu mīhini whakamatao ko te whakahinuhinu, te hiri, te whakamatao me te tātari. I roto i ngā kōpeke maha-puoto, ka taea hoki te whakamahi i te hinu whakahinuhinu hei whakahaere i te tikanga tango.
