Kodi defrost ozizira yosungirako?

Kuphatikizidwa ndi chitsanzo cha kukonzanso kosungirako kozizira kosungirako, ndikuwuzani ukadaulo wa kusungirako kuzizira kozizira.

Kupanga zida zosungirako zozizira

Pulojekitiyi ndi malo osungiramo ozizira ozizira, omwe ndi malo osungiramo ozizira omwe amasonkhana m'nyumba, omwe ali ndi magawo awiri: malo osungiramo kutentha kwapamwamba komanso kusungirako kuzizira kozizira.

Zosungirako zozizira zonse zimaperekedwa ndi mayunitsi atatu a JZF2F7.0 Freon compressor condensing unit, compressor model ndi 2F7S-7.0 open piston single-unit refrigeration compressor, kuzizira ndi 9.3KW, mphamvu yolowera ndi 4KW, ndipo liwiro ndi 600rpm. Firiji ndi R22. Mmodzi mwa mayunitsiwa ali ndi udindo wosungirako kuzizira kwambiri, ndipo mayunitsi ena awiri ali ndi udindo wosungirako kuzizira kozizira. Evaporator yamkati ndi koyilo ya serpentine yolumikizidwa pamakoma anayi komanso pamwamba pa malo ozizira. Condenser ndi gawo lokakamiza la mpweya wozizira. Kugwira ntchito kwa kusungirako kuzizira kumayendetsedwa ndi gawo loyendetsa kutentha kuti liyambe, kuyimitsa ndi kuyendetsa firiji compressor malinga ndi malire apamwamba ndi otsika a kutentha kokhazikitsidwa.

General mkhalidwe ndi mavuto aakulu ozizira yosungirako

Pambuyo pogwiritsira ntchito zipangizo zosungirako zozizira, zizindikiro zosungirako zozizira zimatha kukwaniritsa zofunikira zogwiritsira ntchito, ndipo magawo ogwiritsira ntchito zipangizozo amakhalanso mkati mwazonse. Komabe, zidazo zitakhala zikugwira ntchito kwa nthawi yayitali, pamene chisanu chozizira pa coil chomwe chimatuluka chiyenera kuchotsedwa, chifukwa cha kapangidwe kake Njira yothetsera vutoli ilibe chipangizo chosungirako chosungirako chozizira, ndipo kusungirako kuzizira kwamanja kumatha kuchitidwa. Popeza koyiloyo ili kuseri kwa mashelufu kapena katundu, mashelufu kapena katundu ayenera kusunthidwa pa defrosting iliyonse, yomwe imakhala yovuta kwambiri, makamaka ngati pali katundu wambiri m'malo ozizira. Ntchito yochepetsera madzi ndiyovuta kwambiri. Ngati kukonzanso koyenera sikunachitike pazida zosungirako zozizira, ziyenera kukhudza kwambiri kugwiritsa ntchito bwino kusungirako kuzizira komanso kukonza zida.

Tikudziwa kuti pali njira zambiri zochepetsera kusungirako kuzizira, monga kutsekemera kwa makina, kutsekemera kwa magetsi, kutsekemera kwa madzi ndi kutentha kwa mpweya wotentha, ndi zina zotero. Kutentha kwa gasi wotentha ndikokwera mtengo komanso kodalirika, kosavuta kusamalira ndi kusamalira, ndipo ndalama zake ndi zomangamanga sizili zovuta. Komabe, pali njira zambiri zothetsera gasi wotentha. Njira yanthawi zonse ndi kutumiza mpweya wothamanga kwambiri komanso wotentha kwambiri womwe umatulutsidwa kuchokera ku kompresa kupita ku evaporator kuti utulutse kutentha ndi kuziziritsa, ndikusiya madzi osungunuka alowe mu evaporator wina kuti atenge kutentha ndi kuwukira mu mpweya wocheperako komanso wocheperako. Bwererani ku kuyamwa kompresa kuti mumalize kuzungulira. Poganizira kuti mawonekedwe enieni a malo osungiramo ozizira ndikuti magawo atatuwa amagwira ntchito modziyimira pawokha, ngati ma compressor atatu akuyenera kugwiritsidwa ntchito limodzi, zigawo zambiri monga mapaipi ofananitsa mapaipi, mapaipi ofananira mafuta, ndi mitu yobwereranso mpweya ziyenera kuwonjezeredwa. Kuvuta kwa zomangamanga ndi kuchuluka kwa uinjiniya sizochepa. Pambuyo pa ziwonetsero zobwerezabwereza ndikuwunika, potsirizira pake adaganiza kuti atsatire mfundo yoziziritsa ndi kutentha kutembenuka kwa pampu ya kutentha. Mu ndondomeko yokonzanso iyi, valve ya njira zinayi imawonjezeredwa kuti amalize kusintha kwa kayendedwe ka refrigerant panthawi yowonongeka kwa kusungirako kuzizira. Pa defrosting, kuchuluka kwa refrigerant mu thanki yosungirako madzi pansi pa condenser amalowa condenser, kuchititsa madzi nyundo chodabwitsa wa kompresa. Valve yowunikira ndi valve yoyendetsera kupanikizika imawonjezeredwa pakati pa condenser ndi tanki yosungiramo madzi. Pambuyo pa kukonzanso, pambuyo pa mwezi wa ntchito yoyesera, zotsatira zoyembekezeka zinatheka pa zonse. Pokhapokha pamene chisanu ndi chisanu kwambiri (chiwerengero cha chisanu> 10mm), ngati nthawi yowonongeka ili mkati mwa mphindi 30, compressor nthawi zina imakhala yofooka Pofupikitsa kuzizira kwa kusungirako kuzizira ndi kulamulira makulidwe a chisanu, kuyesera kumasonyeza kuti malinga ngati defrosting ndi theka la ola pa tsiku, makulidwe a chisanu ndi chisanu, osapitirira chisanu, osapitirira 5mm. Kugwedezeka kwamadzimadzi sizichitika. Pambuyo pokonzanso zida zosungirako zozizira, sizinangothandizira kwambiri ntchito yoziziritsa kusungirako kuzizira, komanso kuwongolera magwiridwe antchito a unit. Pansi pa kusungirako komweko, nthawi yogwira ntchito ya unityo yachepetsedwa kwambiri poyerekeza ndi zakale.
