Ko te hinu e whakamahia ana mō te whakahinuhinu i ngā wāhanga nekeneke i roto i te pūwero whakamatao ka kiia ko te hinu whakamatao, e mōhiotia ana hoki ko te hinu whakahinuhinu. E ai ki ngā paerewa a te Manatū Ahumahi Petrochemical, e rima ngā momo hinu whakamatao e hangaia ana i Haina, arā, ko te Nama 13, Nama 18, Nama 25, Nama 30 me te Nama 40 o te paerewa hinonga. I roto i ēnei, ko ngā hinu whakamatao e whakamahia whānuitia ana ko te Nama 13, Nama 18 me te Nama 25, ko ngā pūwero R12 te nuinga o te wā e whiriwhiri ana i te Nama 18, ko ngā pūwero R22 te nuinga o te wā e whiriwhiri ana i te Nama 25.
I roto i te compressor, e whā ngā mahi matua o te hinu whakamatao, te whakahinuhinu, te hiri, te whakamatao me te whakahaere pūngao.
(1) Te whakahinuhinu
Ko te hinu whakamatao i roto i te mahi a te compressor hei whakaiti i te waku me te pakaru o te mahi a te compressor, kia roa ake ai te ora o te compressor.
(2) Te hiri
He mahi hiri tā te hinu whakamatao i roto i te pūwero, kia tutuki ai te pānga hiri i waenganui i ngā peera hurihuri o te pūwero me te mata o te rango, kia kore ai e turuturu te hauhautanga.
(3) Te Whakamatao
Ina whakahinuhinuhia ki te hinu i waenga i ngā wāhanga neke o te pūwero, ka taea e te hinu whakamatao te tango i te wera e puta ana i te wā e mahi ana, kia iti ake ai te pāmahana o ngā wāhanga neke, ā, ka pai ake te whai huatanga me te pono o te pūwero.
(4) Te whakahaere i te pūngao
Mō te pūwero whakamatao me te tikanga whakahaere pūngao, ka taea te whakamahi i te pēhanga hinu o te hinu whakamatao hei mana o te mīhini whakahaere pūngao.
Tuatahi, he aha ngā whakaritenga o ngā taputapu whakamatao i runga i te hinu whakamatao
Nā te whakamahinga o ngā wā rerekē me ngā hauhautanga rerekē, kāore i te ōrite te whiriwhiri hinu hauhautanga mō ngā taputapu whakamatao. Ko ngā whakaritenga mō te hinu whakamatao ko ēnei:
1, matotoru
He mea nui ngā āhuatanga o te matotoru o te hinu whakamatao, arā, ko te whakamahi i ngā momo whakamatao rerekē hei whiriwhiri i ngā momo hinu whakamatao. Mēnā he nui rawa te matotoru o te hinu whakamatao, ka piki ake te kaha o te waku miihini, te wera o te waku me te taipana tīmatanga. Engari, ki te iti rawa te matotoru, ka kore e taea e te nekehanga i waenga i ngā wāhanga te hanga i te kiriata hinu e hiahiatia ana, kia kore ai e tutuki te pānga whakahinuhinu me te whakamatao e hiahiatia ana.
2, pūwāhi pōuri
Ko te pūwāhi paru o te hinu whakamatao ko te whakaiti i te pāmahana ki tētahi uara, ka tīmata te hinu whakamatao ki te whakatō paraffin, ā, ka huri te pāmahana hinu whakahinuhinu hei paru. Me iti iho te pūwāhi paru o ngā taputapu whakamatao e whakamahia ana i roto i te hinu whakamatao i te pāmahana mimiti o te hau whakamatao, ki te kore ka aukati i te takirere whakatere, ka pāngia rānei te mahi whakawhiti wera.
3, pūwāhi whakatōtika
I roto i ngā āhuatanga whakamātautau o te whakamatao, ka aukatihia te rere o te pāmahana e mōhiotia ana ko te pūwāhi tio. Ko ngā taputapu whakamatao e whakamahia ana i roto i te pūwāhi tio o te hinu whakamatao me iti rawa (pēnei i te compressor R22, me raro iho i te -55 te hinu whakamatao).℃), ki te kore ka pā ki te rere o te hauhautanga, ka whakanui ake i te ātete rere, ka hua ake he koretake o te whakawhiti wera.
4, pūwāhi mura
Ko te pūmahana mura o te hinu whakamatao ko te pāmahana iti rawa e whakamahanatia ai te hinu whakahinuhinu ki te wāhi e mura ai tōna kohu ina pā atu ki te mura. Me teitei ake te pūmahana mura o ngā taputapu whakamatao e whakamahia ana i roto i te hinu whakamatao i te pāmahana putanga o te 15 ~ 30℃neke atu rānei, kia kore ai e mura, e kōkare rānei te hinu whakahinuhinu.
5, te pumau matū me te ātete hāora
He pumau te hanganga matū o te hinu whakahinuhinu parakore, kāore e whakapōrearea, kāore hoki e waikura te konganuku. Heoi, ki te mea kei roto i te hinu whakahinuhinu he hauhautanga, he wai rānei, ka waikura, ka waikawa te waikura o te hinu whakahinuhinu, ka waikura te konganuku. Ina whakamahia te hinu whakahinuhinu ki ngā pāmahana teitei, ka puta he kōka. Ki te piri tēnei rauemi ki te pereti takirere, ka pā ki te mahi noa o te pereti takirere, ā, ka ārai i te tātari me te takirere whakatere. Nō reira, me whiriwhiri he hinu whakahinuhinu tio pumau, ā, he ātete ki te waikura.
6, te makuku me ngā poke miihini
Mena he wai kei roto i te hinu whakahinuhinu, ka nui ake ngā huringa matū o te hinu, ka pirau te hinu, ka hua ake te waikura o te konganuku, engari ka puta hoki te "hukapapa" i roto i te takirere whakatere, i te takirere whānui rānei. Kei roto i te hinu whakahinuhinu ngā poke miihini, ka nui ake te pakaru o te mata o ngā wāhanga neke, ā, ka tere te aukati i te tātari me te takirere whakatere, te takirere whānui rānei, nō reira kaua te hinu whakahinuhinu tio e whai poke miihini.
7, mahi whakamātao
I roto i te pouaka tio kua kati-haurua, ā, kua kati katoa, ka hono tika te hinu whakahinuhinu tio me te hauhautanga ki ngā takai motuka me te pito whakamutunga, nā reira me whai āhuatanga pai te hinu whakahinuhinu me te ngaohiko pakaru teitei. He pai te mahi whakahinuhinu o te hinu whakahinuhinu parakore, engari kei roto he wai, he poke me te puehu, ka heke te mahi whakahinuhinu, ā, ko ngā whakaritenga whānui o te ngaohiko pakaru hinu whakahinuhinu o te pouaka tio he 2.5KV, neke atu rānei.
8, nā te rerekētanga o ngā āhuatanga o ngā momo hauhautanga, he rerekē rawa te pāmahana mahi o te pūnaha pouaka whakamātao, ā, ko te tikanga ka taea te whiriwhiri i te hinu whakahinuhinu tio penei: ka taea te whiriwhiri i te matotoru me te iti o te ira tio o ngā taputapu pouaka whakamātao i runga i ngā āhuatanga pāmahana iti; me whiriwhiri i te matotoru me te ira tio o ngā taputapu pouaka whakamātao i runga i ngā āhuatanga pāmahana iti, tere iti rānei;
二、 Ngā whakaritenga mō te whakamahinga o te hinu whakamatao pūwero
1. Ka taea anake te whakamahi i te hinu whakamatao kua tohua mō te pūnaha hauhautanga HFC-134a (R-134a) me ngā wāhanga HFC-134a (R-134a). Ka pāngia te pānga whakahinuhinu o te pūwhakakoi e te hinu whakamatao kāore i te whakahaeretia, ā, mā te whakaranu i ngā momo hinu whakamatao rerekē ka puta te waikura me te pakaru o te hinu whakamatao, ka arahi pea ki te pakaru o te pūwhakakoi.
2. E ai ki te HFC-134a (R-134a) ka taea e te hinu pouaka whakamātao te mimiti tere i te makuku mai i te hau. Me whai i ēnei mahi:
(1) I te wā e wetewetehia ana ngā wāhanga pouaka whakamātao mai i ngā taputapu pouaka whakamātao, me hipoki (hiri) ngā wāhanga i te wā e taea ai hei whakaiti i te urunga mai o te makuku ki te hau.
(2) I te wā e tāuta ana i ngā wāhanga pouaka whakamātao, kaua e tangohia (e whakatuwheratia rānei) te taupoki o ngā wāhanga i mua i te hono atu. Me hono wawe tonu ngā wāhanga o te ara iahiko pouaka whakamātao kia kore ai e uru te makuku ki te hau.
(3) Ko ngā hinu whakahinuhinu kua tohua anake ka taea te whakamahi. Whai muri i te whakamahinga, me hiri tonu te ipu hinu whakahinuhinu. Ki te kore te hinu whakahinuhinu i hiritia tika, kāore e taea te whakamahi anō i muri i te urunga o te makuku.
3. Kaua e whakamahia te hinu whakamatao kua pakaru, kua pōuri hoki, nā te mea ka pā ki te mahi noa o te pūwhakakoi.
4. Me tāpiri e te pūnaha te hinu whakamatao kia rite ki te horopeta kua whakaritea. Mēnā he iti rawa te hinu whakamatao, ka pā ki te whakahinuhinu o te compressor. Mēnā he nui rawa te hinu whakamatao ka pā ki te kaha whakamatao o te pūnaha hauhautanga.
5. Ina tāpirihia te hauhautanga, me tāpiri tuatahi te hinu hauhautanga, kātahi ka tāpirihia te hauhautanga
