Amasistimu amaningi omoya kanye neziqandisi athola amayunithi awo abambayo ngaphandle ngenxa yezizathu ezimbili eziyinhloko. Okokuqala, lokhu kusebenzisa izinga lokushisa elipholile le-ambient ngaphandle ukuze kususwe okunye ukushisa okumuncwa isihwamuko, futhi okwesibili, ukunciphisa ukungcoliswa komsindo.
Amayunithi okujiya ngokuvamile ahlanganisa ama-compressor, amakhoyili e-condenser, amafeni e-condenser angaphandle, othintana naye, ama-relay aqalayo, ama-capacitor, namapuleti esimo esiqinile anamasekhethi. Umamukeli ngokuvamile uhlanganiswa neyunithi yokufingqa yesistimu yesiqandisi. Ngaphakathi kweyunithi yokujiya, i-compressor ngokuvamile ine-heater ngandlela-thile exhunywe phansi noma ku-crankcase. Lolu hlobo lwe-heater luvame ukubizwa ngokuthi ai-heater ye-crankcase.
II-compressor crankcase heateriyisifudumezi sokumelana nesivamise ukuboshelwa phansi kwe-crankcase noma ifakwe emthonjeni ngaphakathi kwe-crankcase ye-compressor.Ama-heaters e-Crankcasezivame ukutholakala kuma-compressor lapho izinga lokushisa le-ambient liphansi kune-evaporator yokusebenza yesistimu.
Amafutha e-crankcase noma amafutha e-compressor anemisebenzi eminingi ebalulekile. Nakuba isiqandisi siwuketshezi olusebenzayo oludingekayo ukuze luphole, uwoyela uyadingeka ukuze kugcotshwe izingxenye ezinyakazayo ze-compressor. Ngaphansi kwezimo ezijwayelekile, kuhlale kunenani elincane lamafutha aphuma ku-crankcase ye-compressor futhi azungeza nesiqandisi kulo lonke uhlelo. Ngokuhamba kwesikhathi, isivinini esifanelekile sesiqandisi ngokusebenzisa ishubhu yesistimu sizovumela lawa mafutha aphunyukile ukuthi abuyele ku-crankcase, futhi kungenxa yalesi sizathu ukuthi uwoyela nesiqandisi kufanele zincibilike zodwa. Ngesikhathi esifanayo, noma kunjalo, ukuncibilika kwamafutha kanye nesiqandisi kungabangela enye inkinga yesistimu. Inkinga ukufuduka kwesiqandisi.
Ukufuduka kuyisenzakalo se-aperiodic. Lena inqubo lapho iziqandisi eziwuketshezi kanye/noma zesitimu zifuduka noma zibuyele ku-crankcase ye-compressor kanye nemigqa yokumunca phakathi nomjikelezo wokuvala shaqa kwe-compressor. Ngesikhathi sokucisha kwe-compressor, ikakhulukazi phakathi nokucisha okunwetshiwe, isiqandisi sizodinga ukuhanjiswa noma sithuthelwe lapho ingcindezi iphansi kakhulu. Ngokwemvelo, uketshezi lugeleza lusuka ezindaweni ezinomfutho ophakeme luye ezindaweni ezinomfutho ophansi. I-crankcase ivamise ukuba nomfutho ophansi kune-evaporator ngoba iqukethe uwoyela. Izinga lokushisa elipholile le-ambient likhulisa umfutho we-vapor ophansi futhi lisiza ukuminyanisa umhwamuko oyisiqandisi oketshezini oluku-crankcase.
Amafutha afakwe esiqandisini ngokwawo anomfutho ophansi we-vapor, futhi kungakhathaliseki ukuthi i-refrigerant isesimweni se-vapor noma isimo se-liquid, izogeleza emafutheni aqandisiwe. Eqinisweni, umfutho womhwamuko kawoyela oyiqhwa uphansi kangangokuthi ngisho noma i-vacuum engu-100 microns idonswa ohlelweni lwesiqandisi, ngeke ihwamuke. Umhwamuko wamanye amafutha aqandisiwe wehliswa ube ama-microns angu-5-10. Uma uwoyela ungenawo ukucindezela komhwamuko ophansi kangako, uzohwamuka noma nini lapho kunomfutho ophansi noma i-vacuum ku-crankcase.
Njengoba ukufuduka kwesiqandisi kungenzeka ngomhwamuko oyisiqandisi, ukufuduka kungase kwenzeke ekukhuphukeni noma ekwehleni. Lapho isitimu esiqandisini sifika ku-crankcase, sizomuncwa futhi sijiyezwe emafutheni ngenxa yokungahlangani kwesiqandisi/samafutha.
Phakathi nomjikelezo omude ovaliwe, isiqandisi esiwuketshezi sizokwakha ungqimba olunemigqa ngaphansi kwamafutha ku-crankcase. Lokhu kungenxa yokuthi iziqandisi eziwuketshezi zisinda kunamafutha. Phakathi nemijikelezo emifushane yokuvala i-compressor, isiqandisi esifudukayo asinalo ithuba lokuzinza ngaphansi kwamafutha, kodwa sisazohlangana namafutha ku-crankcase. Phakathi nenkathi yokushisisa kanye/noma izinyanga ezibandayo lapho kungadingeki ukupholisa umoya, abanikazi bezindawo zokuhlala bavame ukuvala ukunqanyulwa kwamandla kuyunithi yokupholisa yangaphandle ye-air-conditioning. Lokhu kuzodala ukuthi i-compressor ingabi nakho ukushisa kwe-crankcase ngoba i-heater ye-crankcase iphelelwe amandla. Ukufuduka kwesiqandisi ku-crankcase kuzokwenzeka phakathi nalo mjikelezo omude.
Uma inkathi yokupholisa iqala, uma umninikhaya engayivuli i-breaker yesifunda okungenani amahora angu-24-48 ngaphambi kokuqala iyunithi ye-air conditioning, ugwebu olukhulu lwe-crankcase kanye nokucindezela kuzokwenzeka ngenxa yokufuduka kwesikhathi eside kwesiqandisi esingazungezi.
Lokhu kungabangela ukuthi i-crankcase ilahlekelwe izinga elifanele likawoyela, futhi kulimaze ama-bearings futhi kubangele ukwehluleka kwemishini ngaphakathi kwe-compressor.
Ama-Crankcase heater aklanyelwe ukusiza ukulwa nokufuduka kwesiqandisi. Indima ye-heater ye-crankcase ukugcina amafutha ku-crankcase ye-compressor ezingeni lokushisa elingaphezu kwengxenye ebanda kakhulu yesistimu. Lokhu kuzoholela ekutheni i-crankcase ibe nengcindezi ephakeme kancane kuneyo yonke isistimu. Isiqandisi esingena ku-crankcase sizobe sesikhishwa umoya bese siphindiselwa emuva emugqeni wokumunca.
Ngezikhathi ezingezona zomjikelezo, ukufuduka kwesiqandisi ku-compressor crankcase kuyinkinga enkulu. Lokhu kungase kubangele umonakalo omkhulu we-compressor
