Iwe unofanirwa kuziva izvi nezve firiji yakatakurwa mufiriji!

Ndeapi mafriji aripo? Muchokwadi, iyo yakajairika firiji inotakura imvura, iyo ine zvinotevera hunhu:

Kutanga, mutengo wemvura wakachipa kwazvo.

Sezvo mutengo wemvura uri wakachipa, ndiyo yekutanga sarudzo yezvinotonhora, uye mvura zvakare iri nyore kuwana. Munzvimbo zhinji umo zviwanikwa zvemvura zvisina kunyanya kushomeka, kushandisa mvura sefiriji ndiyo sarudzo yakanakisa.

Zvakare, semvura inotonhora, kunwa kwemvura hakuzove kwakanyanya. Nezve iko kwese kushandiswa kwemabhizimusi kuri kukosheswa, inogona kutsanangurwa sedonhwe mubhaketi. Naizvozvo, inokodzera chero firiji uye bhizinesi rinoda kuburitsa mafiriji pamusoro pe 0 degrees Celsius.

Chechipiri, kunaka kwemvura kunovimbiswa zviri nyore.

Kunyangwe paine zvakawanda zvinokonzeresa pahunhu hwemvura, mhando yemvura iri nyore kwazvo kuvimbisa, kusanganisira jekiseni remapiritsi emvura akachena, kana kusefa kuri nyore kwemvura kuona mhando yemvura. Mvura iri nyore-kushandisa-inotakura inotonhora system. Mumiriri.

Chechitatu ndechekuti mvura haina njodzi uye inoputika.

Mvura inochengetedzeka kwazvo inotakura mafiriji mafiriji. Iyo firiji haisiyo yega mhando yeFreon. Naizvozvo, mvura yechando zvakare inotakura firiji, uye hapana imwe chete mhando. Pamusoro pemvura, pane mamwe mafomu, senge Inonyanya kuzivikanwa mvura yemunyu, pamwe nezvinwiwa zvakaita se ethylene glycol, methanol kana ethanol. Chero bedzi iri mvura uye ichisangana nehunhu uye nezvinodiwa nemvura inotonhora (firiji inotakura) yefiriji, inogona kushandiswa zvakajairika.

Kana iri mvura yemunyu, inorganic salt mvura inofanira kushandiswa. Musiyano mukuru pakati pemvura isina munyu nemvura ndeyekuti iyo yekutanga inogona kushanda patembiricha pazasi pe 0 degrees Celsius, nepo mvura, sezvatinoziva tese, 0 degrees Celsius ndiyo nzvimbo yayo inotonhora. Iyo yakaoma nechando uye nekudaro haigone kushanda.

Kune mafiriji akaita se ethylene glycol, kunyangwe mukana wekushandisa kwayo wakaderera kana uchienzaniswa nemvura, ichine imwe chikamu chemusika. Nekudaro, iyi mhando yemvura yechando (firiji) inofanirwa kutarisisa kudzivirira moto uye kupisa.
