Hei tāpiri atu ki te tauira o te whakatikatika hangarau rokiroki matao, ka kōrero atu ahau ki a koe i te hangarau whakarewa rokiroki matao.
Te hanganga o ngā taputapu rokiroki makariri
He kaupapa rokiroki makariri hou tēnei, he rokiroki makariri kua huihuia ki roto, e rua ngā wāhanga: he rokiroki makariri pāmahana teitei me te rokiroki makariri pāmahana iti.
E toru ngā waeine whakakōkī o te pūwero JZF2F7.0 Freon e whakaratohia ana mō te rokiroki makariri katoa, ko te tauira pūwero he pūwero whakamatao kotahi-wāhanga piston tuwhera 2F7S-7.0, ko te kaha whakamatao he 9.3KW, ko te mana whakauru he 4KW, ā, ko te tere he 600rpm. Ko te hauhautanga he R22. Ko tētahi o ngā waeine he kawenga mō te rokiroki makariri pāmahana teitei, ā, ko ētahi atu e rua he kawenga mō te rokiroki makariri pāmahana iti. Ko te whakapūmahana o roto he koiri nakahi e piri ana ki ngā pakitara e whā me te tihi o te rokiroki makariri. Ko te whakakōkī he waeine koiri hau whakahauhau. Ko te mahi o te rokiroki makariri e whakahaerehia ana e te waeine whakahaere pāmahana hei tīmata, hei whakamutu me te whakahaere i te pūwero whakamatao kia rite ki ngā rohe o runga me raro o te pāmahana kua whakaritea.
Te āhua whānui me ngā raruraru matua o te rokiroki makariri
I muri i te whakamahinga o ngā taputapu rokiroki makariri, ka taea e ngā tohu o te rokiroki makariri te whakatutuki i ngā whakaritenga o te whakamahinga, ā, kei roto hoki ngā tawhā whakahaere o ngā taputapu i te awhe noa. Heoi, i muri i te whakamahinga o ngā taputapu mō tētahi wā, me tango te paparanga hukapapa i runga i te koiri mimiti, nā te hoahoa kāore he taputapu whakarewa rokiroki makariri aunoa o te otinga, ā, ko te whakarewa rokiroki makariri ā-ringa anake ka taea te mahi. Nā te mea kei muri i ngā whata, i ngā taonga rānei te koiri, me neke ngā whata, ngā taonga rānei mō ia whakarewa, he tino uaua tēnei, inā koa he maha ngā taonga kei roto i te rokiroki makariri. He uaua ake te mahi whakarewa. Ki te kore e mahia te whakatikatika e tika ana ki ngā taputapu rokiroki makariri, tera pea ka pā kino ki te whakamahinga noa o te rokiroki makariri me te tiaki i ngā taputapu.
Mahere whakatikatika whakarewa hukapapa rokiroki matao
E mōhio ana mātou he maha ngā huarahi hei whakarewa i te rokiroki makariri, pērā i te whakarewa ā-ringa, te whakarewa hiko, te whakarewa rehu wai me te whakarewa hau wera, me ētahi atu. He nui ngā raruraru o te whakarewa ā-ringa kua whakahuatia ake nei. He ohanga, he pono hoki te whakarewa hau wera, he ngāwari ki te tiaki me te whakahaere, ā, ehara i te mea uaua te haumi me te hanga. Heoi, he maha ngā otinga mō te whakarewa hau wera. Ko te tikanga noa ko te tuku i te hau pēhanga teitei me te pāmahana teitei i tukuna mai i te pūwero ki te evaporator hei tuku i te wera me te whakarewa, ā, ka tukuna te wai kua whakakōpiritia ki roto i tētahi atu evaporator hei mimiti i te wera me te mimiti ki roto i te hau pāmahana iti me te pēhanga iti. Hoki atu ki te momi pūwero hei whakaoti i te huringa. I te mea ko te hanganga tūturu o te rokiroki makariri ko te mahi motuhake a ngā waeine e toru, ki te whakamahia ngā pūwero e toru i te wā kotahi, me tāpiri he maha ngā wāhanga pērā i ngā paipa whakataurite pēhanga, ngā paipa whakataurite hinu, me ngā pane hau whakahoki. Ehara i te mea iti te uauatanga o te hanga me te nui o te hangarau. Whai muri i ngā whakaaturanga me te tirotiro maha, i whakatauhia kia whakamahia te kaupapa matua o te whakamatao me te whakawhiti whakamahana o te waeine papu wera. I roto i tēnei mahere whakatikatika, ka tāpirihia he takirere ara-whā hei whakaoti i te huringa o te ahunga rere o te hauhautanga i te wā e whakarewahia ana te rokiroki makariri. I te wā e whakarewahia ana, ka uru te nui o te hauhautanga i roto i te tāke rokiroki wai i raro i te whakapūmau ki te whakapūmau, ka puta te āhuatanga hama wai o te compressor. Ka tāpirihia he takirere tirotiro me te takirere whakahaere pēhanga i waenganui i te whakapūmau me te tāke rokiroki wai. Whai muri i te whakatikatika, i muri i te marama o te mahi whakamātautau, ka tutuki te hua e tumanakohia ana i te nuinga. Mena he tino matotoru te paparanga hukapapa (te toharite o te paparanga hukapapa > 10mm), mena kei roto i te 30 meneti te wā whakarewa, i ētahi wā ka ngoikore te compressor. Mā te whakapoto i te huringa whakarewa o te rokiroki makariri me te whakahaere i te matotoru o te paparanga hukapapa, e whakaatu ana te whakamātautau mena he hawhe haora te whakarewa i te rā, ko te matotoru o te paparanga hukapapa e kore e neke ake i te 5mm, ā, ko te āhuatanga ru wai compressor kua whakahuatia i runga ake nei e kore e puta. I muri i te whakatikatika i ngā taputapu rokiroki makariri, ehara i te mea i tino ngāwari ake te mahi whakarewa o te rokiroki makariri, engari i pai ake hoki te whai huatanga o te mahi a te waeine. I raro i te kaha rokiroki kotahi, kua tino whakaitihia te wā mahi o te waeine i tērā o mua.
