Tekau tau te roa o tana mahi hei tohunga whakamatao, ā, i whakaakona e ia ngā wheako tiaki whakamatao rokiroki matao whai hua, he mea tawhito, he mea whai hua hoki.
Tuatahi, i whakaaroaro ahau mō tēnei mea, ā, me kōrero ahau mō te āhua o te mahi noa o te mīhini rokiroki makariri (mīhini piston)
1 Me whakarite kia 1/2 te taumata hinu o te pūaha tirotiro hinu (kia pai ai tōna whakahinuhinu)
2 Te pāmahana o te hauhautanga. Kei te momo hauhautanga tēnei (kaua te R22 e whakamahia whānuitia ana e neke ake i te 145 °C, ā, ka tirohia te pēhanga e rite ana i roto i te ripanga)
3 Me teitei ake te pāmahana momi i te pāmahana mimiti 5-15°C (ko te pāmahana rokiroki tango 5-10°C he rite ki te pāmahana mimiti). Ko te rerekētanga i waenga i te pāmahana momi me te pāmahana rokiroki ko te 0-5 °C te mea tika ake. (e rite ana ki te ripanga rapu)
4 Ka taea e te wehewehe hinu te whakahoki aunoa i te hinu
5 Ko te pāmahana hinu noa kia 40-60℃, (ko ētahi mīhini he whakamahana pouaka hiko)
6 Me 0.15-0.3MP te pēhanga hinu compressor kia teitei ake i te pēhanga momi
rapurongoā
1. Ka mutu ohorere te mahi a te pūwero i te wā e mahi ana
He tikanga ārai tēnei i te nuinga o te wā
(1) Ina iti te taumata hinu, ka mahi te whakawhiti ina iti iho i te uara tiaki (tirohia mēnā kei te turuturu te hinu i te pūnaha, ā, mēnā kei te mahi noa te hinu)
(2) He nui rawa te pēhanga o te putanga hau, he nui ake i te uara tiaki, ka mahi te whakawhiti (tirohia te whakamararatanga wera o te pūwhakapūngao)
(3) He iti rawa te pēhanga hinu whakahinuhinu, ā, kei te mahi te rāihe tiaki pēhanga rerekētanga (tirohia te pūnaha whakahinuhinu)
(4) Te taumaha rawa o te motuka, (inehia te iahiko, whakatikatikahia te kawenga o te waeine kia hoki ki te āhua noa)
2. He tino teitei rawa te pēhanga o te putanga hau i te wā e oma ana te compressor
(1) Kāore i te rawaka te marara o te wera whakapūmau (tirohia ngā taputapu whakapūmau, te rere o te wai, te rere o te hau rānei)
(2) Te nui rawa o te kohi hinu i roto i te pūwhakapūngao (te kohi hinu e mimiti ana)
(3) He hau kei roto i te pūnaha (me whakawātea te korehau i mua i te whakatikatika, he pai ake te whakaroa i tētahi wā, ā, me whakamātau te tikanga whakaputa hau i te pito teitei o te pūwhakamātao)
(4) He nui rawa te hauhautanga i roto i te pūnaha (e mimiti ana te hauhautanga nui)
3. Te whiu mākū o te pūwero (huka pūwero)
(1) He nui rawa te whakatuwheratanga o te takirere whānui, ā, kua kī tonu te hau whakahoki i te wai (whakatikatikahia te takirere whānui)
(2) Ka pakaru te takirere solenoid, ā, ka haere tonu te tuku wai i muri i te whakaweto. Me te wai ina hoki anō te hiko (whakakapia, whakatikahia rānei te takirere solenoid)
(3) He nui rawa te hauhautanga me te mimiti ngoikore (ka turuturu te hauhautanga nui rawa)
(4) Kāore i te pai te pai o ...
4. Kāore e taea te tīmata i te pūwero hiko i te ara tika, ā, ka tirohia te hapa hiko whānui mā te whakamahi i te mita maha.
(1) Kāore i tika te whakahaere i te kati tiaki o te pūwero. Kāore te whakawhiti i tautuhia anō (i tautuhia anō, i whakapotohia rānei hei whakatika i te hapa, kātahi ka whakaora).
(2) Kua motuhia te pūtake hiko, ā, kua pā te fiusi (tirohia te pūtake hiko me te fiusi)
(3) Kāore te hononga tīmatanga, te whakapā rānei i te pai (whakakapia, whakatikahia rānei)
(4) He hapa te pūoko whakamahana, te pūoko rānei (tirohia ki te mita, ā, whakakapia mēnā kua pakaru)
(5) Kāore i te tika te tautuhinga o te kaiwhakahaere pēhanga (whakarerekētia kia rite ki te hiahia)
(6) Kua pakaru te motuka compressor (tirohia te ātete i waenga i ngā takai)
5. He hapa te takirere whānui (ina whakakapia te takirere whānui, ka ōrite ki te pāmahana mahi, ā, ka ōrite te āputa ki te kaha whakamatao o te compressor)
(1) poraka hukapapa,
Take: He nui te wai i roto i te hauhautanga.
Āhuatanga: Te hukapapa e rere ana me te whakarewa i te wā e mahi ana.
Otinga: Whakamahia te tikanga whakamahana me te whakawhānui hei whakaoti rapanga mō te wā poto, whakakorea rawatia te whakaora me te whakakapi i te tātari maroke.
(2) Te aukati paru
Take: He nui rawa ngā poke i roto i te pūnaha, ā, kāore i te tino tupato te tāutanga. Te tauine waikura whakarewa, me ētahi atu.
Āhuatanga: Kāore te mīhini whakapūngao e hukapapa, ā, kāore hoki e whakamatao. Engari he iti, he kino rānei te pēhanga whakahaere.
Otinga: tangohia te takirere whānui ka horoia ki te hinu reo-rahi
(3) Ngā turuturu o te takirere whakawhanui
Take: ngā turuturu o te pūoko pāmahana, ngā turuturu o te tinana takirere, ngā turuturu o te tikanga pūoko pāmahana o te tinana takirere
Te āhuatanga: kāore he whakamatao, kāore te pānga i te pai, he rite te turuturu i roto i te tinana takirere ki te aukati paru
Otinga: Whakakapia, whakakotahi rānei i te tinana takirere
(4) Te whakatikatika hē
Take: He iti rawa, he nui rawa rānei te whakatuwheratanga
Āhuatanga: Ka hukapapa katoa te tinana takirere ina nui rawa te whakatuwheratanga, ā, ina nui rawa te whakatuwheratanga, ka hukapapa te putanga o te tinana takirere, kāore he hukapapa, ā, ka hoki te pūwero ki te hau me te wai.
Otinga: whakatikatikahia te takirere whakawhanui ki te tūranga tika
6. Te rahunga o te tātari
take, aukati
Āhuatanga: kua hukapapa te mata, kāore e ranea te wai, ā, kāore e taea te mahi whakamatao i te āhua noa
Otinga: whakakapi
Tikanga tātari rahunga pouaka whakamātao
1. kia kite
(1) He tomairangi, kāore he hukapapa i te haurua o muri o te mīhini whakapūngao. Kāore i te rawaka, kei te turuturu rānei te hauhautanga (mēnā kua whakatikatikaina tika te takirere whānui, ā, kāore he hapa)
(2) Kāore he huka i te haurua o runga, ā, kua huka te haurua tuarua. He nui rawa te utu o te hauhautanga (mēnā kua whakatikatikaina tika te takirere whānui, ā, kāore he hapa)
(3) Kāore he tomairangi, he huka rānei i roto i te paipa momi, ā, kāore i te rawaka, kāore rānei i te turuturu te hauhautanga

2. Whakarongo
(1) Takirere whānui, ka rangona te rere o te wai i te āhua noa. Oro Sisi Kāore e ranea te hauhautanga, ki te kore e rangona te oro, kua āraia.
3. pā
Te anga o te pūhiko, te rango, te paipa whakatōtō, te tomokanga me te putanga tātari, te whakatau mēnā he paru, he ārai rānei.
te pakaru o te pūhiko
1. Porotakaroa
He raruraru hinu, he paru, he kore hinu rānei. Me te pāmahana hinu whakahinuhinu.
2. He tangi rerekē o te rango
Kua pakaru te pereti takirere, he iti rawa te āputa o te rango, ā, he nui rawa te āputa o te pine
3. He tangi te hinu o te pouaka whakakā
Ka tukinga te porowhita ki te hinu, ka wetekina ngā tīwiri, ā, he nui rawa te āputa o te hononga.
4. Ka iti haere te nekehanga o te pūwero
Te nui rawa o te āputa o te piston
