Njengenjineli yobuchwephesha esebenze kwinkqubo yesikhenkcisi, eyona ngxaki iyingxaki kufuneka ibe yingxaki yokubuya kweoyile yenkqubo. Xa inkqubo isebenza ngokuqhelekileyo, inani elincinci leoli liya kuqhubeka lishiya i-compressor kunye negesi yokukhupha. Xa umbhobho wenkqubo uyilwe kakuhle, ioli iya kubuyela kwi-compressor, kwaye i-compressor inokuthi ifakwe ngokupheleleyo; ukuba kukho ioli eninzi kwinkqubo, ichaphazela kakubi ukusebenza kwe-condenser kunye ne-evaporator; ioli encinci ebuyela kwi-compressor kunokushiya i-compressor, ekugqibeleni yonakalise i-compressor; i-refueling i-compressor, igcina kuphela inqanaba leoli ixesha elifutshane; imibhobho echanekileyo kuphela ngokuyila kuphela, ingaba inkqubo inokulinganisela kweoli, kwaye ke ukusebenza ngokukhuselekileyo kwenkqubo kunokufezekiswa.
Ekuqaleni. Uyilo lombhobho wokufunxa
1. Umbhobho wokufunxa oxwesileyo kufuneka ube nethambeka elingaphezulu kwe-0.5% ecaleni kwendlela yokuhamba kwerhasi yesikhenkcisi;
2. Indawo enqamlezileyo yombhobho wokufunxa othe tyaba kufuneka iqinisekise ukuba umlinganiselo wokuhamba kwerhasi awukho ngaphantsi kwe-3.6m/s;
3. Kumbhobho wokufunxa ngokuthe nkqo, izinga lokuhamba kwerhasi kufuneka liqinisekiswe lingekho ngaphantsi kwe-7.6-12m/s;
4. Isantya sokuhamba kwegesi esingaphezu kwe-12m / s asikwazi ukuphucula kakhulu ukubuyiswa kweoli, eya kuvelisa ingxolo ephezulu kwaye iholele ekunciphiseni uxinzelelo oluphezulu kumgca wokufunxa;
5. Emazantsi kumgca wokufunxa othe nkqo, makumiselwe i-oyile emile okwe-U;
6. Ukuba umphakamo womgca wokufunxa othe nkqo ungaphezulu kwe-5m, kufuneka kumiselwe i-oyile emile okwe-U kwi-5m nganye eyongezelelweyo;
7. Ubude be-oyile yokubuyisela i-U-shaped bend kufuneka ibe mfutshane kangangoko kunokwenzeka ukuphepha ukuqokelela ngokugqithiseleyo kweoli;
Okwesibini, uyilo lombhobho wokufunxa umphunga
1. Xa isistim ingawusebenzisi umjikelo wokukhutshwa, umgibe omile okwe-U kufuneka usetwe kwindawo yokuphuma ye-evaporator nganye. Ukuthintela i-refrigerant yolwelo ukuba ingaphumi kwi-compressor phantsi kwesenzo sobunzima ngexesha lokuvala;
2. Xa umbhobho we-suction riser uxhunywe kwi-evaporator, kufuneka kubekho umbhobho onqamlekileyo kunye ne-bend interception phakathi, ukwenzela ukuba inzwa yokushisa ifakwe ngesibindi; ukuthintela ivalve yokwandisa ukuba ingasebenzi kakuhle.
Okwesithathu, Uyilo lombhobho wokukhupha
Xa i-condenser ifakwe phezulu kune-compressor, i-U-bend iyadingeka kwi-inlet ye-condenser ukukhusela i-oyile ekubuyeleni kwicala lokukhutshwa kwe-compressor ngexesha lokuvalwa, kwaye inceda ukukhusela i-refrigerant yolwelo ukuba ingaphumi kwi-condenser. buyela umva kwicompressor.
Isine, uyilo lwemibhobho yolwelo
1. Umbhobho wolwelo ngokuqhelekileyo awunayo imiqobo ekhethekileyo kwisantya sokuhamba kwefriji. Xa i-valve ye-solenoid isetyenziswe, izinga lokuhamba kwefriji kufuneka libe ngaphantsi kwe-1.5m / s;
2. Qinisekisa ukuba ifriji engena kwivalve yokwandisa ilulwelo olupholileyo;
3. Xa i-refrigerant pressure ye-liquid iyancipha kwi-saturation yayo, inxalenye yefriji iya kukhanya kwigesi.
