ʻŌlelo

ʻO ka hoʻohālikelike a me ka hoʻolauna ʻana o ka mea hoʻoheheʻe wai ʻoihana

Ma muli o nā mea hoʻohui kemika, hiki ke hoʻokaʻawale ʻia nā mea hoʻoheheʻe chiller ʻoihana i 5 mau ʻāpana: nā mea hoʻohuihui inorganic, freon, nā mea hoʻoheheʻe hydrocarbon saturated, nā mea hoʻoheheʻe hydrocarbon unsaturated, a me nā mea hoʻoheheʻe azeotropic. E like me ka condensing puʻe, chiller refrigerants hiki ke hoʻokaʻawale 'ia i 3 waeʻano: kiʻekiʻe-mehana (haʻahaʻa-pressure) refrigerants, medium-mehana (medium-pressure) refrigerants, a me haʻahaʻa-mehana (kiʻekiʻe-pressure) refrigerants. ʻO nā refrigerants i hoʻohana nui ʻia i nā chillers ʻoihana ʻo ammonia, freon, a me nā hydrocarbons.

I ka hoʻomaka ʻana o ka hoʻomohala ʻana i ka ʻoihana, ua hoʻohana ʻia ʻo R12 a me R22 i ka hapa nui o nā mea hoʻonaninani ʻoihana. ʻO ka mana hoʻomaha o R12 he nui loa, a he kiʻekiʻe hoʻi kona ikaika. Akā ʻo R12 ka mea i hōʻino nui i ka papa ozone a ua pāpā ʻia i ka hapa nui o nā ʻāina.

Hoʻohana ʻia nā refrigerants R-134a, R-410a, a me R-407c, i ka hoʻokō ʻana i nā koi palekana o ka honua. S&ʻO kahi mea hoʻoheheʻe ʻenehana :

(1) R-134a (Tetrafluoroethane) Mea hoʻoheheʻe

ʻO R-134a kahi pahu hau i ʻike ʻia ma ke ao holoʻokoʻa i hoʻohana mau ʻia ma ke ʻano he pani no R12. Loaʻa iā ia kahi mahana evaporation o -26.5°C a kaʻana like i nā waiwai thermodynamic like me R12. Eia naʻe, ʻaʻole like me R12, ʻaʻole ʻino ka R-134a i ka papa ozone. Ma muli o kēia, hoʻohana nui ʻia ia i nā ea ea kaʻa, ʻoihana a me nā ʻōnaehana refrigeration ʻoihana, a ma ke ʻano he mea hoʻohua no ka hana ʻana i nā mea insulation plastic paʻakikī. Hiki ke hoʻohana ʻia ʻo R-134a e hana i nā mea hoʻoheheʻe hui ʻia, e like me R404A a me R407C. ʻO kāna noi nui ma ke ʻano he mea hoʻoheheʻe ʻē aʻe i ka R12 i nā ea ea kaʻa a me ka refrigeration refrigeration.

(2) R-410a mea hoʻoheheʻe

Nā Pono Kino a me Kemika: Ma lalo o ka mahana a me ke kaomi maʻamau, ʻo R-410a kahi mea hoʻoheheʻe chlorine-free, fluoroalkane, non-azeotropic i hui pū ʻia. He kinoea hoʻoheheʻe ʻole ʻia i hoʻopaʻa ʻia i loko o nā pahu kila. Me ka Ozone Depletion Potential (ODP) o 0, ʻo R-410a he mea hoʻoheheʻe hoʻopōmaikaʻi ʻia i ka honua ʻaʻole e hōʻino i ka papa ozone.

Noi Nui: Hoʻohana nui ʻia ʻo R-410a ma ke ʻano he pani no R22 a me R502. Ua ʻike ʻia no kona maʻemaʻe, haʻahaʻa haʻahaʻa, non-combustibility, a me ka hana hoʻoluʻu maikaʻi loa. ʻO ka hopena, hoʻohana nui ʻia i nā ea ea hale, nā ea liʻiliʻi pāʻoihana, a me nā ea ea waena.

(3) R-407C mea hoʻoheheʻe

Nā Pono Kino a me Kemika: R-407C he fluoroalkane non-azeotropic i hui pū ʻia ma lalo o ka mahana maʻamau a me ke kaomi. He kinoea hoʻoheheʻe ʻole ʻia i hoʻopaʻa ʻia i loko o nā pahu kila. Loaʻa iā ia ka Ozone Depletion Potential (ODP) o 0, e hoʻolilo iā ia i mea hoʻoheheʻe pili i ke kaiapuni ʻaʻole e hōʻino i ka papa ozone.

Noi Nui: Ma keʻano he pani no R22,ʻo R-407C ka mea iʻikeʻia e kona maʻemaʻe, haʻahaʻa toxicity, non-combustibility, a me ka maikaʻi hoʻoluʻu hana, hoʻohana nuiʻia i nā ea ea hale a me nā ea liʻiliʻi liʻiliʻi.

I kēia au o ka ulu ʻana o ka ʻoihana, ua lilo ka mālama ʻana i ke kaiapuni i mea koʻikoʻi nui, e hana ana i ka "carbon neutrality" i mea nui. I ka pane ʻana i kēia ʻano, S&He mea hana chiller ʻoihana ke hoʻoikaika nei e hoʻohana i nā mea hoʻoheheʻe eco-friendly. Ma ka hoʻoikaika pū ʻana i ka ikehu a me ka hōʻemi ʻana i nā hoʻokuʻu, hiki iā mākou ke hana i ka hana ʻana i kahi "kauhale honua" i ʻike ʻia e nā ʻāina kūlohelohe maoli.
