Iyini imiphumela yezinga lokushisa likawoyela, umehluko wengcindezi kawoyela, nezinga likawoyela elingavamile lama-colders asezimbonini?

Njengamanje, i-piston type chiller igcina uwoyela wokugcoba kukhrankcase ye-compressor, kuyilapho i-screw type chiller inohlelo oluzimele lukawoyela wokuthambisa, indawo yalo yokugcina uwoyela, kanye nesibambisi-manzi esisetshenziswa ngokukhethekile ukunciphisa izinga lokushisa likawoyela. Ngakho-ke, kungakhathaliseki ukuthi izinga lokushisa likawoyela, umehluko wengcindezi kawoyela kanye nezinga likawoyela kufanelekile noma cha kuzoba nomthelela obalulekile ku-chiller.

1. Izinga lokushisa lamafutha

Izinga lokushisa likawoyela lisho izinga lokushisa lamafutha okugcoba lapho i-chiller isebenza. Ukushisa kwamafutha kunethonya elibalulekile ku-viscosity yamafutha okugcoba. Uma izinga lokushisa lamafutha liphansi kakhulu, i-viscosity yamafutha izokhula, i-fluidity izokwehla, futhi akulula ukwenza ifilimu yamafutha afanayo, ngakho-ke umphumela wokugcoba olindelekile awukwazi ukufezwa, futhi uzophinde ubangele isivinini sokugeleza. kawoyela ukunciphisa, ukunciphisa inani lokuthambisa, kanye nokusetshenziswa kwamandla kwephampu kawoyela. Khulisa; uma izinga lokushisa likawoyela liphezulu kakhulu, i-viscosity yamafutha izokwehla, futhi ifilimu kawoyela ngeke ifinyelele ukushuba okuthile, okwenza kube nzima ukuthi izingxenye ezigijimayo zimelane nokucindezela okudingekile kokusebenza, okuholela ekuwohlokeni kwesimo sokugcoba, sithuthukiswe. ukugqoka kwezingxenye ezihambayo, nokwehluleka kwe-chiller.

Okwesibili, umehluko wengcindezi kawoyela

Kuyisiqinisekiso sokuthi uwoyela wokugcoba udinga ukunqoba ukumelana nokugeleza lapho ugelezela ezingxenyeni ezihlukahlukene zokusebenza epayipini lesistimu kawoyela ngaphansi kokushayela kwephampu kawoyela. Ngaphandle komehluko owanele wengcindezi kawoyela, akunakwenzeka ukuqinisekisa ukuthi isistimu yokugcoba inokugcoba okwanele kanye nevolumu yamafutha okupholisa kanye namandla adingekayo ukushayela idivayisi yokulungisa amandla. Ngakho-ke, umehluko wengcindezi kawoyela wesistimu kawoyela opholile kufanele uqinisekiswe ebangeni elifanele ukuze kube lula iyunithi Izingxenye ezihambayo zigcotshwe ngokugcwele futhi zipholile, futhi idivayisi yokulungisa amandla ingasetshenziswa ngendlela eguquguqukayo.

I-3. Izinga lamafutha

Kubhekiselwa ezingeni lamafutha okugcoba esitsheni sokugcina uwoyela. Isitsha sokugcina uwoyela se-chiller sifakwe idivayisi yokubonisa izinga likawoyela. Ngokuvamile, kushiwo ukuthi izinga likawoyela esitsheni sokugcina uwoyela kufanele libe ngu-5mm ngaphezu nangaphansi komugqa ovundlile omaphakathi wengilazi yokubona. Inhloso yokucacisa izinga likawoyela iwukuqinisekisa ukuthi iphampu kawoyela idinga uwoyela owanele ukwenza ukujikeleza kukawoyela lapho isebenza. Uma izinga likawoyela liphansi kakhulu, kulula ukubangela amaphampu kawoyela anganele, okungase kubangele ukwehluleka kokusebenza noma ukulimaza imishini. Izinga likawoyela ngokweqile kungenzeka libangele “isiteleka samafutha” se-compressor, okubuye kube uhlobo “lwesiteleka soketshezi”.
