Umoya opholileyo kunyeindawo yokugcina ebandayoukusebenza koxinzelelo kunye neendlela zokukhusela.
I-rinkqubo yokukhenkcisayinkqubo evaliweyo. Ukuqina komoya kwenkqubo yokukhenkcisa emva kokugcinwa kufuneka kuhlolwe ngokungqongqo ukuqinisekisa umgangatho wokugcinwa, ukuphucula ukuthembeka kokusebenza, ukunciphisa ukulahleka kwefriji, kunye nokuphucula ukusebenza kakuhle. Ifriji ingena kakhulu emanzini. Ke ngoko, kuyimfuneko ukujonga ukuqina komoya kwenkqubo yokukhenkcisa.
Kufuneka kuqatshelwe ukuba igesi ye-nitrogen kufuneka isetyenziswe ukugcina uxinzelelo kwinkqubo yokukhenkcisa. I-oksijini yigesi evuthayo. Ukuba i-oksijini isetyenziselwa ukugcina uxinzelelo, inokubangela umlilo okanye ukuqhuma!
- Ukusebenza kokugcina ubushushu obuncinci nobuphakathi kwindawo yokugcina izinto ezibandayo ezincinci neziphakathi:
Kucetyiswa ukuba ucinezele omabini amacala egesi kunye nolwelo ngaxeshanye. Okokuqala, qhagamshela i-pressure gauge kwitshaneli yeenjongo ezininzi yevalvu yokuvala uxinzelelo oluphezulu noluphantsi yecompressor, kwaye ususe izinto ezikwinkqubo yokuqala ezingafanele zibekwe phantsi koxinzelelo olugqithisileyo, njengevalvu yokulawula uxinzelelo lokuphuma komoya kunye nezinye izinto.
Ukuthatha i-refrigerant ye-R22 njengomzekelo, xa uxinzelelo oluphantsi loxinzelelo luyi-1.2MPa, ukutshaja kwe-nitrogen kuyamiswa. Emva kokuba uvavanyo lwecandelo loxinzelelo oluphantsi lugqityiwe, uvavanyo loxinzelelo lwenkqubo yoxinzelelo oluphezulu lwenziwa. Emva kokuba uxinzelelo lwenkqubo yoxinzelelo oluphezulu lunyuswe ukuya kwi-2.5MPa, ukutshaja kwe-nitrogen kuyamiswa. Gcina uxinzelelo kangangeeyure ezingama-24-48.
| Inkqubo yokukhenkcisa | R134a | R22 | R401A, R402A,R404A,R407A,R407B,R407C,R507 |
| Inkqubo yokucinezela ephantsi | 1.2 | 1.2 | 1.2 |
| Inkqubo yobushushu obuphezulu | 2.0 | 2.5 | 3.0 |
Ukulumkela:
Kwiiyure ezi-4 zokuqala zenkqubo, uxinzelelo lwegeyiji yokwehla koxinzelelo aludluli kwi-0.03MPa, kwaye luyaqhubeka luzinzile (ngexesha lenkqubo yovavanyo, ukwehla koxinzelelo ngenxa yotshintsho lobushushu ngokubanzi akudluli uxinzelelo lwegeyiji oluyi-0.01~0.03MPa), kwaye inkqubo yokufriji ingathathwa njengefanelekileyo yokuvavanya ukuvuza.
2. Ukusebenza koxinzelelo lweenkqubo ezininzi
Isixhumi esinee-multi-connector kufuneka sixinzelelwe kumacala omabini ombhobho wegesi kunye nombhobho wolwelo ngaxeshanye, kuba uxinzelelo kumacala omabini egesi kunye nolwelo lunokukhusela iindawo zevalvu ezifana nevalvu yokwandisa ye-elektroniki kwicala leyunithi yangaphakathi yenkqubo yesixhumi esinee-multi-connector ekonakalisweni. I-nitrogen eyomileyo kufuneka isetyenziswe kuvavanyo lokuqina komoya. Yenza i-medium.
Ngexesha lovavanyo lokuqina komoya, akuvumelekanga ukuqhagamshela uvavanyo lombhobho womatshini wangaphandle. Uxinzelelo lovavanyo lwenkqubo ye-R410A yi-4.0MPa, uvavanyo lokuqina komoya kufuneka lusebenzise i-nitrogen njengesixhobo, kwaye i-nitrogen mayibe yomile. Cinezela kancinci, ngamanyathelo amathathu:
| Cinezela | Ixesha | Umsebenzi |
| 0.3MPa | >5 imizuzu | Kunokufumaneka ukuvuza okukhulu |
| 1.5MPa | >5 imizuzu | Kunokufumaneka ukuvuza okukhulu |
| 4.0MPa | iiyure ezingama-24 | Encinci ukuvuza kunokufumaneka |
1. Faka uxinzelelo oluya kwi-0.3MPa, hlala imizuzu emi-5 ukuze kuhlolwe ukuvuza, kwaye unokufumana ukuvuza okukhulu;
2. Faka uxinzelelo kwi-1.5MPa, hlala imizuzu emi-5 ukuze kuhlolwe ukuqina komoya, uze ufumane ukuvuza okuncinci;
3. Faka uxinzelelo kwi-4.0MPa, hlala imizuzu emi-5 ukuze kuvavanywe amandla, kwaye kungafunyanwa amadyungudyungu amancinci.
Emva kokucinezela ukuya kuxinzelelo lovavanyo, gcina uxinzelelo iiyure ezingama-24, kwaye ujonge ukuba uxinzelelo luyehla na. Ukuba uxinzelelo aluhli, lufanelekile.
Uluhlu lovavanyo lwenkqubo yovavanyo lwe-R410A kufuneka lube ngaphezulu kwe-4.5MPa
Ukulumkela:
Ukulungiswa koxinzelelo: Xa ubushushu butshintsha nge-1°C, uxinzelelo luyatshintsha ngokuhambelanayo nge-0.01MPa. Ukuba uxinzelelo lufuna ukugcinwa ixesha elide, uxinzelelo kufuneka lwehliswe luye kwi-0.5MPa okanye ngaphantsi. Uxinzelelo oluphezulu lwexesha elide lunokukhokelela ekuvuzeni kweendawo zokuwelda, kwaye kukho iingozi zokhuseleko ezinokubakho;
Uxinzelelo emva kokubanjwa koxinzelelo luchaphazeleka bubushushu obuphakathi. Njengoko ubushushu bunyuka, uxinzelelo nalo luya kunyuka, kwaye njengoko ubushushu busehla, ubushushu nalo buya kwehla. Ukuba ubushushu obuphakathi bebuyi-10°C xa uxinzelelo belugcinwe izolo, kwaye ubushushu bunyuke ngequbuliso ukuya kuma-25°C namhlanje, ngoko ke ukuba ubushushu buyi-15°C, igeyiji yoxinzelelo iya kwehla, kwaye kuqhelekile ukuba uxinzelelo lwegeyiji lube yi-38.4kgf/cm².
AEmva kokuba uvavanyo loxinzelelo lwe-nitrogen lufanelekile, yomisa inkqubo nge-vacuum. Qhagamshela i-vacuum gauge kwaye usebenzise i-vacuum pump ixesha elingaphezulu kweeyure ezi-2. Ukuba ayikwazi ukufikelela kwi--755mmHg, qhubeka nokupompa iyure e-1. Emva kokufikelela kwi--755mmHg, ingafakwa iyure e-1, kwaye iyafaneleka ukuba i-vacuum gauge ayinyuki.
