Nā hiʻohiʻona o Freon R22 Refrigerant

ʻO kahi freon hoʻohana ākea ʻo Freon. ʻO ia ka manawa hui o nā hydrocarbons saturated, ʻike ʻia e micro-toxicity, ʻaʻohe ʻaʻala, ʻaʻohe makaʻu o ka pahū, kūpaʻa kemika maikaʻi, ʻaʻohe hopena i ka wai, a ʻaʻohe popopo i ka mea hao. Aia kekahi ʻano nui o Freon a no ka hōʻalo ʻana i ka sophistication o ke kākau ʻana i kāna mole molekiola a no ka maʻalahi ʻana o ka hoʻopaʻanaʻau, ua haku ka poʻe i kahi moʻo o nā code maʻalahi no nā ʻano like ʻole o Freon e like me R12, R22 a me R502, a pēlā aku. laʻana o R22 (CHLF2) e hoʻolauna i kāna mau ʻano, a like nā pahu hau ʻē aʻe.

R22 nonflammable a ʻaʻohe xplosive. Ke wehe ʻia i ke ahi hāmama, hoʻopau ʻo R22 i loko o ke kinoea ʻino i kapa ʻia ʻo CoCl2. No laila, koi ʻia ka ea kūpono no ka ʻōnaehana hōʻoluʻolu i ka wā e hoʻoponopono ai i ka compressor refrigerator me ke ahi ākea. ʻOiai

hoʻoponopono, hoʻoliʻiliʻi i ke kaiapuni hana. Hiki i ka R22 ke hana lōʻihi i ka ipu kila a keleawe paha ma lalo o ke ana wela mai 135 a 150 ° C, a hoʻomaka e decompose ma luna o kēlā mehana. Ke hana nei me ka aila paʻahau, hoʻokuʻu ia i ke kalapona mai ka aila me ka ʻole o ka hopena o ka wai a me nā mea wai, e hana i ke kalapona a ke noho pū me ka hao, e pala ia ma 500 ° C.

ʻO ka kiko paila paila o R22 -40.8 ° C. ʻO R22 kahi anuanu mahana wela. Ke hoʻohana ʻia ka wai e like me ke anuanu hōʻoluʻolu, ʻaʻole e ʻoi aku ka pihi condensation ma mua o 1.53 MPa, a ke hoʻohana ʻia ka makani ma ke ʻano he mea hōʻoluʻolu, ʻaʻole e ʻoi aku ka pihi condens ma mua o 2.16 MPa (ua kāpae ʻia ka air tropical tropical).

ʻO ka solubility o ka wai ma R22 he 10 mau manawa i ʻoi aku ma mua o R12, a ʻo ka haʻahaʻa o ka mahana, ʻoi aku ke kiʻekiʻe o ka wai, no laila koi ʻia ʻaʻole e ʻoi aku ka nui o ka wai ma R22 ma mua o 40 a 60mg / L (ppm).

Loaʻa i ka R22 micro-solubility i ka aila lubricating. Hoʻopau lākou i loko o ka pahu pump o compressor a me condenser, a ke kaʻawale lākou i ka evaporator, hoʻololi ka solubility me ka mahana. ʻO ke permeability o R22 ʻoi aku ka kiʻekiʻe ma mua o R12, no laila ʻoi aku ka koi o kāna sila, a ʻo ka hiki i ka pahu hau o ka nui o ka unit ma kahi o 40% ʻoi aku ka nui ma mua o R12. He maikaʻi ka hana uila a R22 a me ka hana hoʻōlapa maikaʻi, ʻoiai i loko o ke kaʻina wai, kiʻekiʻe ke kūmau dielectric a haʻahaʻa ka pale pilikino. ʻO ke kumu o ka dielectric kiʻekiʻe ʻo ia ka mea e hōʻemi ai ke kūpale hoʻoliʻiliʻi ma muli o nā impurities trace. Ke kāwili ʻia ia me ka aila lubricating, e hoʻēmi nui ka hiki o ka insulate. Pono e nānā kūikawā i nā impurities o ka mea hoʻoulu uila uila ke hoʻohana nei i ka pae 2 i ka ʻōnaehana paʻa.
