He mea nui te mahi a te rūma makariri tauira i roto i te tiaki kai, te rongoā, me te mahi kawe taonga. Kei te piki haere tonu te hiahia o te ao mō te rokiroki e whakahaerehia ana te pāmahana, ā, kei te whakawhānui tonu i tēnei mākete. E ai ki te Global Cold Chain Alliance, kua neke atu i te 720 miriona mita pūtoru te kaha rokiroki makariri o te ao i te tau 2024. He mea motuhake te rūma makariri tauira nā te ngāwari, te tāutanga tere, me te pumau o te mahi wera.
Hanganga me ngā Wāhanga Matua o ngā Rūma Matao Whakarerekē
He wāhangarūma makaririhe mea hanga mai i ngā panera whakamahana kua oti te hanga, ngā pūnaha whakamatao, ngā waeine whakahaere, me ngā taputapu hiri. Ko ngā panera whakamahana he mea whakamahi i ngā matua pahuka polyurethane, PIR rānei. E ai ki ngā whakaritenga tūturu mō te pāmahana whakamatao, ko te matotoru paerewa o te panera kei waenga i te 75 mm ki te 200 mm. He 100 mmpapa polyurethaneko te tikanga ka eke ki te kawe wera o te 0.022 W/m·K, e tutuki ai te nuinga o ngā hiahia rokiroki pāmahana-waenga.
Ka whakamahia e ngā mata o ngā panera he rino pania ki te tae, he rino kore waikura rānei. Ko te matotoru o te rino kei waenga i te 0.4 ki te 0.6 mm. Ātete ēnei rauemi ki te waikura, ā, ka tautoko i te horoinga auau. Ka hono pūmau ngā panera e ngā pūnaha cam-lock, e ngā pūnaha hook-lock rānei. Ka whakawhāitihia e tēnei hanganga te turuturu o te hau ki raro iho i te 0.5 m³/m²·h i raro i ngā whakamātautau pēhanga paerewa.
Ko ngā pūnaha pouaka whakamātao te pūtake mahi. Ko ngā momo pūwero noa ko ngā waeine piston panuku me ngā waeine piston haurua-hermetic. Ko te kaha whakamatao he maha ngā wā kei waenga i te 3 kW ki te 50 kW mō ia pūnaha. Ko ngā rūma makariri pāmahana-waenga e mahi ana i waenga i te 0°C me te 5°C. Ko ngā rūma makariri pāmahana-iti ka eke ki te −18°C ki te −25°C. Ka pupuri ngā kaiwhakahaere mamati i te tika o te pāmahana i roto i te ±0.5°C.
Ka pāngia hoki te mahi e ngā tatau. Ko ngā tatau he mea hono, he mea reti rānei, he mea whakamahana ngā anga tatau. Ka ārai tēnei hoahoa i te hukapapa ina whakamahia i raro i te −10°C. Mā te whakaurunga tika o ngā wāhanga ka pumau te mahi me te roa o te ora ratonga.
Ngā Painga Matua o ngā Pūnaha Rūma Matao Modular
He nui te whai huatanga o ngā rūma makariri tauira. Ka whakaitihia e ngā panera kua oti te hanga i mua i te wheketere te mahi i te papaanga. Nā ngā panera whakamahana kua oti te hanga me te maha o ngā tīma hanga, ka oti te tāutanga o tētahi rūma makariri tauira 100 m² i roto i ngā rā 3–7. He maha ngā wā e hiahiatia ana ngā rūma makariri raima tuku iho neke atu i te 30 rā. Mā te tuku tere ake ka whakaitihia ngā utu mahi mā te 25%.
Ko te ngāwari tētahi atu painga matua. Mā ngā pūnaha whakarerekētanga ka ngāwari te whakawhānui, te neke rānei. Ka taea e ngā kaiwhakamahi te whakanui ake i te rahinga rokiroki mā te tāpiri i ngā panera me te whakapai ake i te kaha o te pouaka whakamātao. Ka pai tēnei urutau ki te rokiroki kai o te wā me ngā mahi kawe taonga e tipu haere ana.
He painga nui tonu te whai huatanga o te pūngao. Ka eke te pahuka polyurethane matotoru ki te 40–45 kg/m³. Ka whakaitihia e tēnei hanganga te whakawhiti wera, ā, ka whakaitihia te wā e mahi ai te pūngao. E whakaatu ana ngā rangahau ka taea e ngā rūma makariri modular te whakaiti i te whakapaunga pūngao mā te 15–20% ki te whakaritea ki te rokiroki makariri i hangaia ki te pereki i raro i ngā āhuatanga ōrite.
Ka pai ake hoki te whakahaere i te akuaku. Ka āraihia e ngā mata whakarewa maeneene te tipu o ngā huakita. Ko ngā rūma makariri e whakamahia ana mō te rokiroki kai he maha ngā wā ka tutuki i ngā paerewa HACCP. Ka ārai te hiri tika i te haukū me te hanganga pokepokea ai. Ka tautokohia e tēnei āhuatanga te rokiroki haumaru o te mīti, te miraka, ngā hua me ngā huawhenua.
Ka whakapakari ake te mana whakahaere utu i te rongonui o te mākete. Ko ngā rūma makariri tauira ka whakaiti i te haumitanga tuatahi mā te 10–20% ki te whakaritea ki ngā whare rokiroki makariri tuku iho. Mā te whakamahinga rauemi matapae me te whakaputanga paerewa ka āwhina i te whakahaere tika i ngā tahua.
Te Tāutanga, te Tiaki, me te Ora Ratonga
Mā te tāutanga ngaio ka pumau te pono mō te wā roa. Me whakataurite e ngā kaiwhakauru te turanga i roto i te ±5 mm neke atu i te 10 mita. Ka puta te taumahatanga o te panera me te turuturu o te hau i ngā turanga kāore i te ōrite. Me whakau e ngā kaiwhakauru ngā raka kame kia ōrite kia mau tonu te tūnga o te panera.
Me aro nui ki te mahi hiri. Ka pania e ngā kaiwhakauru he silicone kounga kai ki ngā hononga katoa o te panera. Me mau tonu ngā ārai kohu, inā koa i roto i ngā rūma makariri iti te pāmahana. Ki te kore e pai te hiri, ka nui ake te hukapapa, ā, ka piki ake te whakapaunga pūngao tae atu ki te 30%.
Whai muri i te tāutanga ka tīmata te pūnaha pouaka whakamātao. Me whakakorekore e ngā tohunga hangarau te pūnaha i raro i te 500 microns i mua i te whakakī i te hauhautanga. Mā te whakakī tika i te hauhautanga ka pai ake te mahi a te pūwero, ā, ka whakaiti i te pakaru. Ko ngā hauhautanga noa ko te R404A, te R448A, me te R507A, i runga i ngā ture ā-rohe.
Mā te tiaki auau ka roa ake te ora o te ratonga. Me horoi e ngā kaiwhakamahi ngā pūwero whakamahana ia marama kia mau tonu ai te pai o te whakawhiti wera. Me tirotirohia ngā hiri tatau ia ono marama. Mā te tiaki tika ka taea e ngā rūma makariri modular te mahi pono mō ngā tau 15–20.
Ka ātete ngā mata rino me ngā paninga ārai-waikura ki te waikura i roto i ngā taiao makuku. Mēnā ka whakamahia tika, ka noho tonu te hekenga o te mahi whakamarumaru i raro i te 5% mō ngā tau tekau. Ka tautokohia e tēnei pakari te pumau o te mahi mō te wā roa.
He otinga rokiroki makariri whai hua, ngāwari, me te penapena hiko ngā rūma makariri ā-pūrere. Mā ngā wāhanga paerewa ka māmā ake te hoahoa me te tāutanga. Mā ngā tawhā pāmahana tika ka pumau te whakahaere pāmahana. Mā te hanga tere, ngā utu iti, me te roa o te ora ratonga, ka tautoko tonu ngā rūma makariri ā-pūrere i te whanaketanga mekameka makariri o te ao puta noa i ngā ahumahi kai, rongoā, me te kawe waka.
Kōwhiria he kaiwhakarato ratonga kia āta tupato
Ko ngā painga o te rokiroki makariri ā-pūrere ko te watea o te hanganga me te tino whai hua ohanga. Nā tēnei ka nui ake te tono ki ngā kaiwhakarato o ngā otinga rokiroki makariri.
I tētahi taha, me whai ngā kaiwhakarato i tētahi taumata o te kaha whakauru rauemi i roto i te mekameka umanga rokiroki makariri. Mā tēnei ka māmā ake te hoko mai i ngā momo wāhanga me te whakatutuki i ngā hiahia ritenga a ngā kaiwhakamahi i te wā kotahi, inā koa mō te aroturuki raraunga me ngā whakaoho haumaru.
I tētahi atu taha, me whai wheako hoahoa nui ngā kaiwhakarato, ā, me kaha ki te whakahaere tika i te kounga me ngā taipitopito o ia wāhanga. I roto i te hanganga o te rokiroki makariri, ki te kore he whare putunga nui he teitei e hiahia ana ki tētahi ararewa, ko te wāhanga tino roa ko te huihuinga o te hanganga rokiroki makariri. Ko te roa o ngā panera rokiroki makariri me te tika o ngā tūranga matau e whakatau tika ana i te maeneene o te hanganga.
Hei tāpiritanga, ki te kore te hoahoa o te tinana rokiroki e tino ōrite ki ngā rahi me te taumaha o ngā wāhanga matua pēnei i ngā mīhini hau makariri me ngā whakapūmau hau, ka ara ake pea he arai hanga, he tūponotanga haumaru rānei. Ka nui ake te hiahia mō te māramatanga o te kaiwhakarato ki ngā hua e pā ana.
Ko Harbin Dong`an Building Sheets Co., Ltd. tētahi kaiwhakarato otinga rokiroki makariri matua i Haina. He matatau ngā raina whakaputa a te kamupene mō ngā panera rokiroki makariri, ka taea te whakahaere tika i te tika o te tukatuka o ngā panera. I taua wā anō, he nui ngā wheako hoahoa rokiroki makariri a te kamupene, ā, ka taea e ia te whirihora i ngā wāhanga utu-pai kia rite ki ngā hiahia o te kaiwhakamahi, ka tere ake te whai huatanga o te hanga.
