Njengonjiniyela ochwepheshe osebenze ohlelweni lwesiqandisi, inkinga enzima kakhulu kufanele kube inkinga yokubuyisela uwoyela ohlelweni. Uma uhlelo lusebenza ngokujwayelekile, inani elincane lamafutha lizoqhubeka nokushiya i-compressor negesi yokukhipha. Uma ipayipi yesistimu iklanywe kahle, amafutha azobuyela ku-compressor, futhi i-compressor ingagcotshwa ngokugcwele; uma kunamafutha amaningi ohlelweni, kuthinta kabi ukusebenza kahle kwe-condenser ne-evaporator; amafutha amancane abuyela ku-compressor kunokushiya i-compressor, ekugcineni elimaza i-compressor; i-refueling i-compressor, igcina izinga likawoyela kuphela isikhathi esifushane; amapayipi alungile kuphela Ngokuklama, ingabe uhlelo lungaba nebhalansi kawoyela enhle, bese ukusebenza okuphephile kwesistimu kungafinyelelwa.
Okokuqala. Umklamo wepayipi lokumunca
1. Ipayipi lokumunca elivundlile kufanele libe nomthambeka ongaphezu kuka-0.5% ngasendleleni yokugeleza kwegesi efrijini;
2. Ingxenye enqamulayo yepayipi lokudonsa elivundlile kufanele iqinisekise ukuthi izinga lokugeleza kwegesi alikho ngaphansi kuka-3.6m/s;
3. Epayipini lokumunca elima mpo, izinga lokugeleza kwegesi kufanele liqinisekiswe lingabi ngaphansi kuka-7.6-12m/s;
4. Izinga lokugeleza kwegesi elikhulu kune-12m / s alikwazi ukuthuthukisa ngokuphawulekayo ukubuya kwamafutha, okuzokhiqiza umsindo ophezulu futhi kuholele ekunciphiseni kokucindezela okukhulu emgqeni wokudonsa;
5. Phansi komugqa ngamunye wokumunca omile, kufanele kumiswe ukubuyisa kawoyela okumise okwe-U;
6. Uma ubude bomugqa wokumunca ome mpo budlula ama-5m, ukubuyisela uwoyela okumise okwe-U kufanele kumiswe kuwo wonke ama-5m angeziwe;
7. Ubude bokugoba uwoyela obufana no-U kufanele bube bufushane ngangokunokwenzeka ukuze kugwenywe ukunqwabelana kwamafutha ngokweqile;
Okwesibili, idizayini yepayipi lokumunca i-evaporator
1. Uma isistimu ingawusebenzisi umjikelezo wokuphuma, isicupho esimise u-U kufanele sisethwe lapho kuphuma khona i-evaporator ngayinye. Ukuvimbela isiqandisisi se-liquid ukuthi singagelezi ku-compressor ngaphansi kwesenzo samandla adonsela phansi ngesikhathi sokuvala;
2. Uma ipayipi lokukhuphuka elidonsayo lixhunywe ku-evaporator, kufanele kube nepayipi evundlile kanye ne-interception bend phakathi, ukuze inzwa yokushisa ingafakwa ngesibindi; ukuvimbela i-valve yokunweba ukuthi ingasebenzi kahle.
Okwesithathu, Ukuklanywa kwepayipi lokukhipha umoya
Lapho i-condenser ifakwe ngaphezu kwe-compressor, i-U-bend iyadingeka ekungeneni kwe-condenser ukuvimbela uwoyela ukuthi ungabuyeli ohlangothini lokukhipha lwe-compressor ngesikhathi sokuvala, futhi kusiza ukuvimbela isiqandisi esiwuketshezi ukuthi singagelezi sisuka ku-condenser. geleza ubuyele ku-compressor.
Okwesine, umklamo wamapayipi oketshezi
1. Ipayipi eliwuketshezi ngokuvamile alinayo imingcele ekhethekile kuzinga lokugeleza kwesiqandisi. Uma i-valve ye-solenoid isetshenziswa, izinga lokugeleza kwesiqandisi kufanele libe ngaphansi kuka-1.5m / s;
2. Qinisekisa ukuthi isiqandisi esingena ku-valve yokwandisa siwuketshezi olupholile;
3. Lapho ingcindezi yefriji ye-liquid yehla ekucindezelweni kwayo kokugcwala, ingxenye yesiqandisi izokhanya ibe yigesi.
