ʻO ka
pahu hau
he mea hoʻoheheʻe e mālama i kahi mahana haʻahaʻa mau, a he huahana kīwila hoʻi e mālama i ka meaʻai a i ʻole nā mea ʻē aʻe i kahi kūlana haʻahaʻa haʻahaʻa mau. Aia i loko o ka pahu he mea hoʻomaloʻo, kahi keʻena a i ʻole kahi pahu no ka mea hana hau e maloʻo ai, a me kahi pahu waihona me kahi mea hoʻoheheʻe. ʻO ka nui o nā pahu hau uila o ka hale he 20 a 500 mau lita. A laila, e nānā kākou i ke kumu o ka mōʻaukala a me ka ulu ʻana o ka
Pahu Pahu Liiki
.
ʻO ke kumu mōʻaukala o ka pahu hau.
Ke kaʻina hana hoʻomohala o ka pahu hau.
ʻO ke kumu mōʻaukala o ka pahu hau
Ua ʻike nā kānaka mai ka wā kamaliʻi ʻo ka meaʻai i mālama ʻia ma nā mahana haʻahaʻa ʻaʻole hiki ke pohō. Ma mua o 2000 BC (20th century BC), ua hoʻomaka ka poʻe kamaʻāina kahiko o nā muliwai ʻo ʻEuperate a me Tigris ma Babulona, West Asia, e kūkulu i ka hau i loko o nā lua e hoʻoinu ai i ka ʻiʻo. I ka moʻokūʻauhau Shang (mai ke kenekulia 17 BC a hiki i ke kenekulia 11 BC), ua ʻike pū ʻo Kina i ka hoʻohana ʻana i ka hau no ka mālama ʻana i ka meaʻai. I ka Middle Ages, nui nā ʻāina i ʻike ʻia ma nā ʻāina he nui e hoʻokomo i nā pahu hau i loko o nā keʻena wai kūikawā a i ʻole nā keʻena pōhaku e mālama ai i ka meaʻai. A hiki i ka makahiki 1850, keia ano Ua kūʻai ʻia ʻo Top Freezer Refrigerator ma ʻAmelika Hui Pū ʻIa.
ʻAʻole i komo ka huaʻōlelo 'fridge' i ka ʻōlelo ʻAmelika a hiki i ka waena o ke kenekulia 17 ma ke Komohana. Me ka ulu ʻana o ke kūlanakauhale, ua ulu mālie ka ʻoihana hau. Ua hoʻohana mālie ʻia e nā hōkele, nā hōkele, nā halemai, a me kekahi poʻe kālepa ʻike kūlanakauhale no ka mālama ʻana i ka ʻiʻo, ka iʻa, a me ka pata. Ma hope o ke Kaua Kivila ʻAmelika (1861-1865 AD), ua hoʻohana ʻia ka hau i loko o nā kaʻa pahu hau, a no ka hoʻohana kīwila. I ka makahiki 1880, he hapalua o ka Ua kūʻai ʻia ka Retro Fridge ma New York, Philadelphia, a me Baltimore, a ua komo ka hapakolu o nā pahu hau i kūʻai ʻia ma Bosetona a me Chicago. Loaʻa i nā huahana like nā pahu hau.
ʻAʻole maʻalahi ke kūkulu ʻana i kahi pahu hau e like me kā mākou e manaʻo ai. I ka makahiki mua o 1800, ua ʻike ka poʻe mea hana i ka ʻike thermophysical koʻikoʻi i ka ʻepekema refrigeration. Ma ke Komohana, ua manaʻo ka poʻe he mea pono ke pale i ka hoʻoheheʻe ʻana o ka hau i ka pahu hau maikaʻi loa , a ʻo ka manaʻo maʻamau i kēlā manawa he hewa ia no ka mea ʻo ka hoʻoheheʻe ʻana o ka hau e hoʻokani i ke ʻano o ka refrigeration. Ua nui ka hooikaika ana i na la mua no ka malama ana i ka hau, e like me ka uhi ana i ka hau iloko o na pakeke i hiki ole i ka hau ke hana i kana hana. ʻAʻole hiki i ka hopena o ke kenekulia 19 i lanakila ka poʻe mea hana i ka loaʻa ʻana o ke koena kūpono o ka insulation a me ke kahe e pono ai no kahi pahu hau kūpono.
Ke kaʻina hana hoʻomohala o ka pahu hau
Akā i ka makahiki 1800, ua loaʻa i kahi kanaka mahiʻai ʻo Maryland noʻeau, ʻo Thomas More, ke ala kūpono. Loaʻa iā ia kahi mahiʻai ma kahi o 20 mau mile mai Wakinekona, kahi o ke kauhale ʻo George Town ke kikowaena mākeke. I kona hāʻawi ʻana i ka pata i ka mākeke me ka ʻO Bottom Freezer Refrigerator o kāna hoʻolālā, ua ʻike ʻo ia e hele ana nā mea kūʻai aku ma mua o ka pata hehee wikiwiki i loko o nā bākeke hoʻokūkū a uku iā ia ma mua o ke kumukūʻai makeke no ka mea hou, paʻakikī, a ʻoki maikaʻi. He paona pata. Wahi a Moore, ʻo kekahi pōmaikaʻi o kāna pahu hau, ʻaʻole pono ka poʻe mahiʻai e hele i ka mākeke i ka pō e mālama i kā lākou huahana.
I ka makahiki 1822, ua ʻike ke kauka lapaʻau kaulana ʻo Faraday e lilo ka carbon dioxide, ammonia, chlorine, a me nā kinoea ʻē aʻe i wai ma lalo o nā kūlana paʻi, a e lilo i kinoea ke hoʻohaʻahaʻa ʻia ke kaomi. Ma ke kaʻina o ka hoʻololi ʻana mai ka wai a i ke kinoea, e hoʻomoʻa nui ia i ka wela, e hāʻule koke ka mahana a puni. ʻO kēia ʻike ʻia e Faraday i hāʻawi i kahi kumu kumu no nā hanauna hope e hana i nā ʻenehana refrigeration artificial e like me nā compressors. Ua haku ʻia e Harrison ka mea hoʻoheheʻe hau mua i ka makahiki 1851. ʻO Harrison, ka mea nona ka 'Geelong Advertiser' o Australia, e hoʻomaʻemaʻe ana i ke ʻano me ka ether i kona ʻike ʻana he hopena koʻikoʻi ko ka metala. He wai ʻo Etera me ka haʻahaʻa haʻahaʻa o ka paila ʻana, a hiki i ka evaporative endothermic phenomena. Ua hoʻokumu ʻo Harrison i kahi pahu hau me ka hoʻohana ʻana i ka ether a me ka a 3 Puma Puu Puu Puka Puka ma hope o ka noiʻi ʻana a hoʻohana ʻia i kahi hale kūʻai waina ma Victoria, Australia, no ka hoʻoluʻu ʻana a me ka hoʻoluʻu ʻana i ka wā o ka hana waina.
I ka makahiki 1873, ua hana ka chemist German a me ka engineer Karl von Linde i ka pahu hau e hoʻohana ana i ka fluorine ma ke ʻano he refrigerant. Hoʻohana ʻo Linde i kahi ʻenekini mahu liʻiliʻi e hoʻokele i ka ʻōnaehana hoʻoemi, no laila e hoʻopili pinepine ʻia ka amonia a e hoʻoheheʻe ʻia e hana i ka refrigeration. Ua hoʻohana mua ʻo Linde i kāna mea hana i ka Sedoumar brewery ma Wiesbaden, e hoʻolālā a hana i kahi pahu hau ʻoihana. Ma hope mai, hoʻomaikaʻi ʻo ia i ka pahu hau ʻoihana. No ka hana ʻana i mea liʻiliʻi, i ka makahiki 1879, ua hana ʻia ka pahu hau mua o ka honua i hoʻopaʻa ʻia. ka pahu hau i hoʻohana ʻia i ka mahu, a i ka makahiki 1891, ua kūʻai ʻia aku he 12,000 mau ʻāpana ma Kelemānia a me ʻAmelika Hui Pū ʻIa. Ua hoʻokomo koke ʻia
ʻO ke kaʻa uila mua e hoʻokele i ka compressor i hana ʻia e nā ʻenekini Suedena ʻo Brighton lāua ʻo Mendes i ka makahiki 1923. Ua kūʻai hope kekahi hui ʻAmelika i kā lākou mau palapala patent a ma 1925 i hana i nā pahu hau uila mua o ka hale. I loko o ka pahu hau uila mua, ua hoʻokaʻawale ʻia ka compressor uila a me ka friji. Hoʻokomo pinepine ʻia ka mea hope i loko o ke kiln ma lalo o ka hale a i ʻole ke keʻena mālama a hoʻopili ʻia i ka mea hoʻoemi uila ma o nā paipu. Ma hope mai, hoʻohui ʻia nā mea ʻelua i hoʻokahi. Ma mua o nā makahiki 1930, ka hapa nui o nā mea hoʻoheheʻe i hoʻohana ʻia e ka pahu hau , e like me ka ether, ammonia, sulfuric acid, a me nā mea ʻē aʻe. ʻaʻole palekana Ma hope mai, hoʻomaka wau e ʻimi i kahi mea hoʻoheheʻe palekana a loaʻa iā Freon. ʻO Freon he mea ʻawaʻawa ʻole, ʻaʻole hoʻopōʻino, ʻaʻole hiki ke puhi ʻia i ka fluorine. Ua lilo koke ia i mea hoʻoheheʻe no nā ʻano mea hoʻoheheʻe a ua hoʻohana ʻia ma mua o 50 mau makahiki. Akā ua ʻike ʻia he hopena ʻino ʻo Freon i ka papa ozone o ka lewa o ka honua. No laila, hoʻomaka hou ka poʻe e ʻimi hou a ʻoi aku ka maikaʻi o ka refrigerants.
Inā hana ʻoe me ka pahu hau a makemake ʻoe e ʻike hou aku e pili ana i kā mākou hui, hiki iā ʻoe ke kamaʻilio me mākou ma ka pūnaewele. ʻO kā mākou pūnaewele kūhelu https://www.feilongelectric.com/.
