Freon - bụ ... okpomọkụ nke Freon. Freon na friji

Onye ọ bụla ụlọ nwere ngwa n'ihi na mmepụta na arụmọrụ nke ndị dị otú a umi na-eji dị freon. Nke a na umi a maara dị ka ihe magburu onwe refrigerant eji fridges otú i nwere ike na-echekwa ihe oriri na njikere nri ogologo karịa na ihere okpomọkụ. Isiokwu a ga-agwa, Freon - bụ na n'agbanyeghị ebe ọ na-eji, ihe okpomọkụ ọ bụ.

History of chọpụtara

Dị iche iche na isi mmalite aha mbụ na nke abụọ ụbọchị njikọ Freon - 1928 na 1931, afọ. Correct na ụbọchị ọmụmụ nke refrigerant 1928 nke afọ. Ọ bụ mgbe ihe pụrụ iche mmiri ọgwụ ụlọ ọrụ Frigidaire, nke bụ a enyemaka nke ụlọ ọrụ General Motors, Thomas Midgley, wetara "ọrụ ebube umi" ma nye ya aha "Freon". Older injinia aku na ulo oru mmepụta a gas, banyere designation Freon-12 dị ka ihe «R» (na translation «Refrigerant» anọchi a refrigerant ma ọ bụ oyi). The abụọ ụbọchị na biakwa obibia nke Freon nepravlno jikọtara, n'ihi na na-ama na 1930 ike kinetic Chemical Company, nke nwere na-arụ ọrụ e kere na-elekwasị anya na-na mmepụta nke ngwaahịa a.

Freon - ihe bụ nke a?

A ngwakọta nke ethane na methane ka fluorinated ala molekụla ibu hydrocarbon nkwekọrịta ebe hydrogen atọm nwere ike nnọchianya site fluorine, chlorine, bromine. Ọtụtụ-eji na friji nkeji (friji, friza, ikuku conditioners na na. N). Ọtụtụ na-eche, Freon - bụ a gas ma ọ bụ a mmiri mmiri? Azịza ziri ezi bụ: umi nwere ike ma nke anụ ahụ ala.

The kasị ahụkarị ụdị Freon

Science mara ihe karịrị 40 iche iche nke umi, ọtụtụ nke na-enwetara industrially. Freon okpomọkụ na nke ọ na Juda, onye ọ bụla ụdị nwere ya onwe:

• R11 - trichlorofluoromethane (t na esi 23,8 ° C).
• R12 - difluorodichloromethane (na kpụ ọkụ n'ọnụ t reflux -29,8 ° C).
• R13 - trifluorochloromethane (na kpụ ọkụ n'ọnụ t reflux -81,5 ° C).
• R14 - tetrafluoromethane (na kpụ ọkụ n'ọnụ t reflux -128 ° C).
• R134A - tetrafluoroethane (esi kpụ ọkụ n'ọnụ na t -26,3 ° C).
• R22 - chlorodifluoromethane (na kpụ ọkụ n'ọnụ t reflux -40,8 ° C).
• R600A - isobutane (na kpụ ọkụ n'ọnụ t reflux -11,73 ° C).
• R410A - hloroftorokarbonat (na kpụ ọkụ n'ọnụ t reflux -51,4 ° C).

A, home friji rụọ ọrụ na freon (Khladone) ọkwa R-22, maka ulo oru na azụmahịa were R-13 ika.

Freon - bụ ize ndụ umi maka ụmụ mmadụ?

Fọrọ nke nta niile ụdị ihe nwere ọjọọ mmiri ịgbọ agbọ, Otú ọ dị, ọ na-eji na jụrụ ihe nke home ngwa, dị ka ndị pusher mmewere ke gas cartridges, ikuku fresheners na ndị ọzọ na aerosols. Ya mere, mgbe spraying cylinder onwe ya na-mma na Freon abatakwa ikuku. Ọ bụrụ na ndị refrigerant na-adịghị ewe iwe na 250 degrees (na nke a okpomọkụ, hapụ nsi) ọ bụ adịghị emerụ mmadụ, nwere ike ghara kwuru na ozone Layer. The ire ere ngwaahịa ibibi ya. Isi kpatara ozone oghere bụ mmepụta na ojiji nke Freon na a elu ọdịnaya nke chlorine ion na bromine.

Mgbake nke ozone Layer nke Earth na belata mmepụta nke na-emerụ CFCs UN mba bịanyere aka na ratified na Montreal Protocol.

Gịnị bụ freon na friji?

Modern Compressor friji na-ọkọnọ n'ụdị ese foto enịm n'ime evaporator, nke na-agụnye a refrigerant. Nke a na umi n'oge esi na vaporization amịkọrọ okpomọkụ si-ulo na odide usoro-enyefe ya na gburugburu ebe obibi. N'ihi nke a ikuku na-mma na chọrọ okpomọkụ, na gas na-alaghachikwuru Compressor na-agbanwe ya ala nke aggregation na a mmiri mmiri. Freon na friji bụ nnọọ nke a evaporator. Na ọzọ okwu, ọ bụ ihe dị mkpa akụrụngwa nke usoro, ekele nke ndị jụrụ ime-ulo nile nke ya na friji unit.

Olee otú ị maara banyere ihihi nke Freon si na ngwa nju oyi

O doro anya na nke a umi - onye nke isi mmiri nke kwesịrị ekwesị ịrụ ọrụ nke akụrụngwa. Freon leakage arụpụta mmebi ngwá na enweghi ike iji ya maka ndị ọzọ na nzube. The kasị eji maka nsogbu a - na evaporator tube mmebi ma ọ bụ n'ichepụta ntụpọ. Ebe ọ bụ na nke a bụ a obodo gas, ihe odorless, ọ gaghị ekwe omume ịchọpụta olfactory anabata.

Otú ọ dị, e nwere ụfọdụ ihe ịrịba ama na a mata ihihi. Freon na friji bụ nsogbu, na mgbe ahụ mebiri emebi tube evaporator, o ji nwayọọ nwayọọ na-amalite na-ada. Mmọdo, ke friji na oyi ulo ikuku okpomọkụ adahade, na wepụchara-amalite ngwa ngwa njọ. Nke a bụ nke mbụ na-egosi na ị chọrọ ka lelee ike n'ezi ihe nke obi jụrụ usoro nke ngwá. Ka kpọtụrụ aha na mbụ, na Freon adịghị ize ndụ mmadụ na okpomọkụ agaghị elu karịa 250 degrees, na ikpo ya ka okpomọkụ n'ụlọ bụ ekwe omume.
