I-air conditioning kanyeisitoreji esibandayoukucindezela ukugcina ukusebenza kanye nezinyathelo zokuphepha.
I-ruhlelo lwesiqandisiiyisistimu evaliwe. Ukuqina komoya kwesistimu yesiqandisi ngemuva kokugcinwa kufanele kubhekwe ngokuqinile ukuze kuqinisekiswe ikhwalithi yesondlo, kuthuthukiswe ukuthembeka kokusebenza, ukunciphisa ukulahlekelwa kwesiqandisi, nokuthuthukisa umnotho wokusebenza. I-refrigerant iyangena kakhulu. Ngakho-ke, kuyadingeka ukuhlola ukuqina komoya kwesistimu yesiqandisi.
Kumele kuqashelwe ukuthi igesi ye-nitrogen kufanele isetshenziselwe ukugcina ingcindezi ohlelweni lwesiqandisi. Umoya-mpilo uyigesi evuthayo. Uma umoya-mpilo usetshenziselwa ukugcina umfutho, ungabangela umlilo noma ukuqhuma!
- Ukusebenza kokucindezela kokugcina okubandayo okuncane naphakathi nendawo:
Kunconywa ukucindezela izinhlangothi zombili zegesi kanye noketshezi ngesikhathi esisodwa. Okokuqala, xhuma i-gauge yokucindezela esiteshini esinezinjongo eziningi se-valve yokuvala ingcindezi ephezulu nephansi ye-compressor, bese ususa izingxenye ohlelweni lwangempela okungafanele zibe ngaphansi kokucindezela okukhulu, njenge-valve elawula ukucindezela kokuhwamuka nezinye izingxenye.
Uma sithatha isiqandisi esingu-R22 njengesibonelo, lapho ingcindezi ephansi ingu-1.2MPa, ukushajwa kwe-nitrogen kuyamiswa. Ngemuva kokuthi ukuhlolwa kwesigaba sokucindezela okuphansi kuqediwe, ukuhlolwa kokucindezela kwesistimu yokucindezela okuphezulu kwenziwa. Ngemuva kokuthi ingcindezi yesistimu yengcindezi ephezulu inyusiwe yaba ngu-2.5MPa, ukushaja kwe-nitrogen kuyamiswa. Gcina ingcindezi 24~48h.
| Isistimu yesiqandisi | R134a | R22 | R401A, R402A,R404A,R407A,R407B,R407C,R507 |
| Isistimu yokucindezela okuphansi | 1.2 | 1.2 | 1.2 |
| Isistimu yokushisa ephezulu | 2.0 | 2.5 | 3.0 |
Izinyathelo zokuzivikela:
Emahoreni angu-4 okuqala esistimu, ingcindezi yegeji yokwehla kwengcindezi ayidluli ku-0.03MPa, bese iqhubeka nokuzinza (ngesikhathi senqubo yokuhlola, ukwehla kwengcindezi ngenxa yokushintsha kwezinga lokushisa ngokuvamile akudluli ukucindezela kwegeji engu-0.01 ~ 0.03MPa), futhi uhlelo lwesiqandisi lungabhekwa njengolufanelekele ukuhlolwa kokuvuza.
2. I-Multi-line system ingcindezi yokugcina ukusebenza
I-multi-connector kufanele icindezeleke ezinhlangothini zombili zepayipi legesi kanye nepayipi eliwuketshezi ngesikhathi esifanayo, ngoba ukucindezela ezinhlangothini zombili zegesi noketshezi kungavikela izingxenye ze-valve ezifana ne-valve yokwandisa i-electronic ohlangothini lweyunithi yangaphakathi yesistimu ye-multi-connector ukuze ingalinyazwa. I-nitrogen eyomile kufanele isetshenziselwe ukuhlolwa kokuqina komoya. yenza i-medium.
Ngesikhathi sokuhlolwa kokuqina komoya, akuvunyelwe ukuxhuma ukuhlolwa kwepayipi lomshini wangaphandle. Ingcindezi yokuhlola yesistimu ye-R410A ingu-4.0MPa, ukuhlolwa kokuqina komoya kufanele kusebenzise i-nitrogen njengomthombo, futhi i-nitrogen kufanele yome. Cindezela kancane, ngezinyathelo ezintathu:
| Cindezela | Isikhathi | Umsebenzi |
| 0.3MPa | > 5 imiz | Ukuvuza okukhulu kungatholakala |
| 1.5MPa | > 5 imiz | Ukuvuza okukhulu kungatholakala |
| 4.0MPa | 24h | Encane ukuvuza kungatholakala |
1. Cindezela ku-0.3MPa, hlala imizuzu emi-5 ukuze uhlole ukuvuza, futhi ungathola ukuvuza okukhulu;
2. Cindezela ku-1.5MPa, hlala imizuzu emi-5 ukuze uhlole ukucinana komoya, futhi uthole ukuvuza okuncane;
3. Cindezela ku-4.0MPa, hlala imizuzu emi-5 ukuze uhlole amandla, futhi kungase kutholakale amabhamuza amahle.
Ngemuva kokucindezela ukucindezela kokuhlolwa, gcina ingcindezi amahora angu-24, futhi ubheke ukuthi ingcindezi iyehla yini. Uma ingcindezi ingehli, iyafaneleka.
I-R410A ibanga legeji yengcindezi yokuhlola uhlelo kufanele libe ngaphezu kuka-4.5MPa
Izinyathelo zokuzivikela:
Ukulungisa ukucindezela: Uma izinga lokushisa lishintsha ngo-1°C, ingcindezi ishintsha ngokuhambisanayo ngo-0.01MPa. Uma ingcindezi idinga ukugcinwa isikhathi eside, ingcindezi kufanele yehliswe ibe ngu-0.5MPa noma ngaphansi. Ukucindezela okuphezulu kwesikhathi eside kungaholela ekuvuzeni kwezingxenye zokushisela, futhi kunezingozi ezingaba khona zokuphepha;
Ingcindezi emva kokubamba ingcindezi ithintwa izinga lokushisa elizungezile. Njengoba izinga lokushisa likhuphuka, ukucindezela kuzophinde kukhuphuke, futhi njengoba izinga lokushisa liwela, izinga lokushisa lizokwehla. Uma izinga lokushisa le-ambient lalingu-10°C lapho ingcindezi igcinwa izolo, futhi izinga lokushisa likhuphuke ngokuzumayo laya ku-25°C namuhla, khona-ke Uma izinga lokushisa lingu-15°C, igeji yokucindezela izokwehla, futhi kuyinto evamile ukuthi ingcindezi yegeji ibe ngu-38.4kgf/cm².
ANgemuva kokuthi ukuhlolwa kwe-nitrogen pressure sekufanelekile, sula uhlelo. Xhuma i-vacuum gauge bese usebenzisa iphampu yevacuum isikhathi esingaphezu kwamahora ama-2. Uma ingakwazi ukufinyelela -755mmHg, qhubeka uyimpompa ihora elingu-1. Ngemva kokufinyelela -755mmHg, ingabekwa ihora elingu-1, futhi ifaneleka uma igeji ye-vacuum inganyuki.
