Isingeniso sezimpawu zesiqandisi esisheshayo

Isiqandisi esisheshayo sakhiwe izingxenye ezinhlanu ngochungechunge: i-compressor, i-condenser, i-evaporator, isihlungi esomile, kanye ne-valve yokunwebeka ye-throttle.Inani elifanele lesiqandisi lijovwa kulo, futhi into kagesi ilawula ukusebenza kwe-compressor ngokwezidingo zemvelo ukuze kuzuzwe isiqandisi nokudlulisa ukushisa.umgomo we.

i-compressor

Umshini owuketshezi oshayelwa okhuphula igesi enengcindezi ephansi iye kwingcindezi ephezulu.Ifriji esheshayo iyinhliziyo yesistimu yesiqandisi.Ihogela igesi enesiqandisi esinezinga lokushisa eliphansi kanye nomfutho ophansi epayipini lokumunca, ishayela i-piston ukuze iliminyanise ngokusebenza kwenjini, futhi ikhipha igesi ebanda kakhulu nenomfutho ophezulu wefriji epayipini lokukhipha umoya ukuze inikeze amandla esiqandisi. umjikelezo.Ngale ndlela, umjikelezo wesiqandisi wokucindezelwa→ukuminyanisa→ukunwetshwa→ukuhwamuka (ukumunca ukushisa) kuyenzeka.

i-condenser

Umhwamuko onesiqandisi onezinga lokushisa eliphezulu kanye nomfutho ophezulu wegazi okhishwa ku-compressor uyajiya ube yisiqandisi esiwuketshezi ngokukhipha ukushisa, futhi ukushisa okumuncwa isiqandisi esivela ku-evaporator kudonswa indawo ephakathi nendawo (umkhathi) ozungeze i-condenser.

I-Evaporator

Isiqandisi esiwuketshezi siguqulwa sibe yisimo segesi lapha.

okomisa okokuhlunga

Ohlelweni lwesiqandisi, umsebenzi wesihlungi esomile ukumunca umswakama ohlelweni lwesiqandisi, ukuvimba ukungcola ohlelweni ukuze kungakwazi ukudlula, futhi kuvimbele ukuvaleka kweqhwa nokuvinjwa okungcolile epayipini lesistimu yesiqandisi.Njengoba i-capillary (noma i-valve yokwandisa) iyingxenye evimbeke kalula yesistimu, isihlungi esomile sivame ukufakwa phakathi kwe-condenser ne-capillary (noma i-valve yokwandisa).

Ukwandisa i-valve ye-throttle

Ukudonsa kanye nokucindezela isiqandisi se-high-pressure liquid esivela kumshini wokugcina uketshezi, ukulungisa nokulawula inani lesiqandisi se-liquid esingena ku-evaporator, ukuze sivumelane noshintsho lomthwalo wefriji, futhi ngasikhathi sinye kuvimbele ukwenzeka kwesando se-liquid. i-compressor kanye nomhwamuko ekuphumeni kwe-evaporator Ukushisa okungavamile.
