4 Kutentha kwa mpweya wa galimoto yamoto sikukwanira, kutentha kwa malo otuluka sikotsika, ndipo kuwerenga pa geji yothamanga kwambiri ndipamwamba.low pressure gauge

Pambuyo pofufuza, chifukwa cha kulephera: kutsegula kwa valve yowonjezera kumakhala kochepa kwambiri, kuchuluka kwa firiji yomwe imalowa mu evaporator ndi yaying'ono, ndipo kutentha kwa mlengalenga sikumatengedwa ndi evaporation, kotero kuti mpweya wozizira umakhala wochepa kwambiri. mgalimoto ndi osakwanira.

Njira yochizira: sinthani screw screw pavalavu yowonjezerandi kutembenuzira mobwerezabwereza kuti muwonjezere kutuluka kwa refrigerant

 

Kuwongolera mpweya pagalimoto sikokwanira

Evaporator imakhala ndi chisanu, ndipo kuwerengera kwapamwamba kwambiri komanso kutsika kwapakati kumakhala kochepa.Pambuyo pofufuza, chifukwa cha kulephera: dzenje lachitsulo mu valavu yowonjezera liribe ntchito ya throttling ndi depressurization, kotero kuti refrigerant yamadzimadzi mu evaporator sichikhoza kukhazikika bwino, kotero kutentha kwa galimoto kumakhala kwakukulu.

Njira yothandizira: kumasula firiji, m'malo mwatsopanovalavu yowonjezera, ndi kudzazanso mufiriji.

 

Pambuyo pagalimoto air-conditioning kompresaimathamanga kwa nthawi, kutentha kwa galimoto kumatsika pang'onopang'ono, ndipo kuwerengera pamagetsi othamanga kwambiri kumakhala kwakukulu.Choyambitsa cholakwikacho ndi chakuti desiccant mu silinda yosungiramo madzi imalowa m'madzi, zomwe zimapangitsa kuti orifice ya valve yowonjezera ikhale yozizira, zomwe zimapangitsa kuti firiji isayende.Kuchuluka kwa refrigerant mu payipi yothamanga kwambiri kumawonjezeka pang'onopang'ono, ndipo chiwonetsero chapamwamba chikuwonjezeka;kachulukidwe wa refrigerant mu dongosolo lotsika kwambiri limachepa pang'onopang'ono, ndipo chiwonetsero chotsika kwambiri chimakhala chochepa.

Njira yochizira: tsitsani makinawo, sinthani tanki yosungiramo madzi, ndipo mudzazenso madziwo kuonetsetsa kuti makinawo alibe madzi ndi gasi.
