Kuchaja kwemuchina wekufiriji kwakakosha pakushanda kwemuchina uyu. Kushaja kwakakwana kuchaita kuti muchina wekufiriji usakwane, kusveta kwecompressor kwakaderera, kutonhora kushoma, uye kutopisa zvakanyanya. Kuchaja zvakanyanya kuchaita kuti muchina wekufiriji wecondenser uve wakanyanya kukwira, muchina wekufiriji wemvura usadzokere shure, uye kutokuvadza muchina wekufiriji. Mazhinji masisitimu ane miganhu yakakodzera pahuwandu hwekuchaja, asi masisitimu madiki ane zvinodiwa zvakanyanya pahuwandu hwekuchaja. Idzi ndidzo nzira sere dzakajairika dzekuchaja muchina wekufiriji uye zvakanakira nezvadzinoipira.
Nzira 1: Kuzadza nemvura
Matanho ekushanda:
1. Isa bhodhoro refiriji rakatarisa pasi pachikero, batanidza pombi yekuzadza nevharuvhu yekuzadza, wobvisa gasi riri mupaipi.
2. Vhura vharuvhu yebhodhoro refiriji nevharuvhu yekuzadza, uye shandisa vacuum yesystem kusveta firiji.
3. Vhara vharuvhu yekubuditsa mvura, tanga compressor, wosiya mvura ichiyerera ichipinda musystem.
4. Tarisa kumanikidzwa kwesystem. Kana kumanikidzwa kwakatarwa kwasvika, vhara vharuvhu yekuzadza wovhura vharuvhu yekubuditsa mvura.
Cherechedza:
Vharuvhu yekumisa yekugamuchira mvura inoshandiswa pakudzora kuti refrigerant ifambe zvakanaka musystem.
Sisitimu iyi inofanira kuendeswa kunzvimbo ine vacuum yakawanda kana yaiswa kekutanga.
Kukwira nekukurumidza kwesimba reutsi kunoratidza kuti condenser izere ne refrigerant.
Zvakanakira nezvayakaipira:
Zvakanakira: Inoshanda kune akawanda masisitimu ekutonhodza.
Zvakashata: Huwandu hwekuzadza mufiriji hunofanirwa kunyatsonzwisiswa, uye huwandu hwekuzadza hunopiwa nemugadziri hunowanzo dikanwa.
Nzira yechipiri: Kuzadza gasi
Matanho ekushanda:
1. Yera huremu hwebhodhoro remufiriji.
2. Batanidza pombi yevharuvhu ye pressure gauge kumavharuvhu ekusveta nekuyera eutsi kuti ubvise gasi riri mupaipi.
3. Vhura vharuvhu yemutsi yebhodhoro refiriji, tanga compressor, uye gadzirisa huwandu hwekuzadza kuburikidza negeji yekumanikidza.
Cherechedza:
Mushure mekuzadza, vhara vharuvhu yebhodhoro refiriji, tarisa mashandiro esystem, uye sarudza kana uchida kuramba uchizadza.
Zvakanakira Nezvakaipa:
Zvakanakira: Yakakodzera masisitimu madiki ane kunyatsozadza kwakanyanya.
Zvakashata: Zvakakodzera chete kana paine zvinhu zvishoma zvinozadza mufiriji (kazhinji hazvipfuuri 12kg).
Nzira 3: Nzira yekuyera
Matanho ekushanda:
Yera huremu hwechinhu chinoiswa mufiriji chakawedzerwa kuhurongwa zvakananga.
Cherechedza:
Inoshanda mumamiriro ezvinhu apo huwandu hwekuchaja hunodiwa hwesisitimu hunozivikanwa uye hunofanira kuchajwa zvizere.
Kana huwandu hwekuchaja huri hushoma, firiji iri musystem inofanira kutanga yaburitswa, yozochajwazve mushure mekugadziriswa.
Zvakanakira nezvayakaipira:
Zvakanakira: Yakakodzera michina yakabatana uye iri nyore kushandisa.
Zvakashata: Huwandu hwechaji chaiyo yesystem hunofanira kuzivikanwa pachine nguva.
Nzira 4: Nzira yazvino
Matanho ekushanda:
1. Isa ammeter yekusimbisa simba pamucheto wemhepo inotonhodza.
2. Batanidza bhodhoro refiriji kune chinozadza mvura chine simba shoma kuti ubvise gasi riri mupaipi.
3. Tanga compressor, vhura vharuvhu yebhodhoro refiriji, tarisa ammeter, uye mira kuchaja kana magetsi asvika pamutengo wakatarwa.
Cherechedza:
Iyo current inokanganiswa nezvinhu zvakawanda, zvakaita sekuchinja kwevoltage, ambient temperature, nezvimwewo.
Zvakanakira nezvayakaipira:
Zvakanakira: Zviri nyore kushandisa.
Zvakashata: Mvura inoyerera inokanganiswa nyore nyore nezvinhu zvekunze uye haina kunyatsojeka.
Nzira 5: Nzira yegirazi
Matanho ekushanda:
Tarisa kuyerera kwerefrigerant kuburikidza negirazi riri mupombi yemvura. Kuyerera kwerefrigerant yemvura inoonekera kunoratidza kuchaja kwakakodzera.
Cherechedza:
Mabhurumu kana kuti kupenya kunowanzo ratidza kuti hapana chinhu chinotonhorera zvakakwana.
Kurasikirwa nekumanikidzwa kwepombi yemvura kunogonawo kukonzera mabhurumu, izvo zvinoda kubatanidzwa nekuongorora mashandiro ehurongwa.
Zvakanakira nezvayakaipira:
Zvakanakira: zviri nyore kuona uye zviri nyore kuona.
Zvakashata: hazvigone kuvimba negirazi rekuona kuti rionekwe, uye dzimwe nzira dzinofanira kubatanidzwa.
Nzira 6: Nzira yekumanikidza
Matanho ekushanda:
1. Isa mageji ekudzvanya muzvikamu zvekudzvanya kwakakwira uye kwakaderera wobatanidza pombi yekuzadza mvura.
2. Tanga compressor, tarisa zviratidzo zvemageji ekudzvanya kwepamusoro neakaderera, uye tarisa huwandu hwekuchaja.
Cherechedza:
Kusakwana kwehuwandu hwemhepo inodzikamisa uye huwandu hwemhepo inobuda mumhepo zvinokanganisa mhedzisiro yekuedzwa kwekumanikidzwa.
Usati waedza, zvakakosha kuve nechokwadi chekuti huwandu hwemhepo yesystem hunoenderana nezvinodiwa.
Zvakanakira nezvayakaipira:
Zvakanakira: kunyatsorurama kuburikidza nekutonga kwekumanikidzwa.
Zvakashata: zvinokanganiswa zvakanyanya nemamiriro ekunze, zvakakosha kuve nechokwadi chekuti system inoshanda zvakanaka.
Nzira 7: Kuverenga nzira yekupisa zvakanyanya
Matanho ekushanda:
Verenga kupisa kwakanyanya nekuyera tembiricha yekusveta uye kumanikidzwa kwepombi yekusveta evaporator.
Cherechedza:
Kupisa kwakanyanya kwe capillary system kunokanganiswa nekumanikidzwa uye kuramba.
Sisitimu yekuwedzera vharuvhu inowanzo wedzera mari, uye kupisa kwakanyanya kunoda kudzorwa pa58℃.
Zvakanakira nezvayakaipira:
Zvakanakira: Inoshanda kune sisitimu yekuwedzera mavharuvhu ine kurongeka kwakanyanya.
Zvakashata: Kushanda kwakaoma uye kunoda kuyerwa kwakanyatsojeka.
Nzira 8: Nzira yekuyera mwero wemvura
Matanho ekushanda:
Vhura nzvimbo yekuyedza mvura iri muchinhu chinogadzikisa mvura kuti uone kana paine mvura iri kubuda mufiriji.
Cherechedza:
Zvigadzikiso zvikuru zvemvura zvinogona kunge zvine zviratidzo zvinoyangarara kuti zvibatsire kuona huwandu hwemvura.
Zvakanakira nezvayakaipira:
Zvakanakira: Zviri nyore kuona uye zviri nyore kuona huwandu hwekuzadza.
Zvakashata: Zvinongoshanda chete kumasisitimu ane mapombi ekuyedza mwero wemvura.
Pfupiso:
Nzira yega yega yekuzadza ine mamiriro ayo, zvakanakira nezvakaipira. Kusarudza nzira yakakodzera kunoda kutariswa kwakazara kwerudzi rwesisitimu, zvinodiwa pahuwandu hwekuzadza uye mamiriro ekushanda. Kune masisitimu madiki, nzira dzekuzadza nekuisa gasi uye dzekuyera ndidzo dzinowanzo shandiswa; nepo kune masisitimu makuru, nzira dzekuzadza nemvura uye nzira dzekumanikidza dzinonyanya kushanda. Pasinei nekuti ndeipi nzira inoshandiswa, mashandiro esisitimu anofanira kunyatso tariswa kuti ive nechokwadi chekuti huwandu hwekuzadza hwakarurama uye kudzivirira kukuvara kwesisitimu.
