Kuphatikiza ndi chitsanzo cha kukonzanso makina osungira zinthu zozizira, ndikukuuzani ukadaulo wosungunula zinthu zozizira zosungiramo zinthu zozizira.
Kapangidwe ka zida zosungiramo zinthu zozizira
Pulojekitiyi ndi malo osungiramo zinthu zozizira omwe amasunga kutentha kwabwino, omwe ndi malo osungiramo zinthu zozizira omwe amakonzedwa mkati, omwe ali ndi magawo awiri: malo osungiramo zinthu zozizira otentha kwambiri ndi malo osungiramo zinthu zozizira otentha kwambiri.
Malo onse osungiramo zinthu zozizira amaperekedwa ndi mayunitsi atatu a JZF2F7.0 Freon compressor condensing, mtundu wa compressor ndi 2F7S-7.0 open piston single-unit refrigeration compressor, mphamvu yoziziritsira ndi 9.3KW, mphamvu yolowera ndi 4KW, ndipo liwiro ndi 600rpm. Refrigerant ndi R22. Chimodzi mwa mayunitsicho chimayang'anira malo osungiramo zinthu zozizira kutentha kwambiri, ndipo mayunitsi ena awiri amayang'anira malo osungiramo zinthu zozizira kutentha kochepa. Evaporator yamkati ndi serpentine coil yolumikizidwa ku makoma anayi ndi pamwamba pa malo osungiramo zinthu zozizira. Condenser ndi unit ya coil yoziziritsidwa ndi mpweya wokakamizidwa. Kugwira ntchito kwa malo osungiramo zinthu zozizira kumayendetsedwa ndi gawo lowongolera kutentha kuti liyambe, liyimitse ndikuyendetsa compressor yoziziritsa malinga ndi malire apamwamba ndi otsika a kutentha komwe kwakhazikitsidwa.
Mavuto onse ndi mavuto akuluakulu osungira zinthu zozizira
Zipangizo zosungiramo zinthu zozizira zikagwiritsidwa ntchito, zizindikiro za malo osungiramo zinthu zozizira zimatha kukwaniritsa zofunikira zogwiritsidwa ntchito, ndipo magawo ogwirira ntchito a zidazo ali mkati mwa nthawi zonse. Komabe, zidazo zitagwira ntchito kwa nthawi yayitali, pamene chisanu pa coil yotuluka madzi chikufunika kuchotsedwa, chifukwa cha kapangidwe kake. Yankho lake lilibe chipangizo chosungunula madzi chodzipangira chokha, ndipo ndi njira yokhayo yosungunula madzi yosungiramo zinthu zozizira yomwe ingachitike. Popeza coil ili kumbuyo kwa mashelufu kapena katundu, mashelufu kapena katundu ayenera kusunthidwa pa kusungunula madzi kulikonse, zomwe zimakhala zovuta kwambiri, makamaka pamene pali katundu wambiri mu malo osungiramo zinthu zozizira. Ntchito yosungunula madzi imakhala yovuta kwambiri. Ngati kukonza kofunikira sikukuchitika pa zipangizo zosungiramo zinthu zozizira, zidzakhudza kwambiri kugwiritsa ntchito bwino malo osungiramo zinthu zozizira komanso kusamalira zipangizozo.
Ndondomeko yokonzanso kusungunuka kwa madzi oundana
Tikudziwa kuti pali njira zambiri zosungunula chisanu chosungiramo zinthu zozizira, monga kusungunula chisanu ndi makina, kusungunula chisanu ndi magetsi, kusungunula chisanu ndi madzi ndi kusungunula chisanu ndi mpweya wotentha, ndi zina zotero. Kusungunula chisanu ndi makina komwe kwatchulidwa pamwambapa kuli ndi zovuta zambiri. Kusungunula chisanu ndi mpweya wotentha ndikotsika mtengo komanso kodalirika, kosavuta kusamalira ndikuwongolera, ndipo ndalama zake ndi kapangidwe kake sikovuta. Komabe, pali njira zambiri zothetsera chisanu ndi mpweya wotentha. Njira yachizolowezi ndikutumiza mpweya wotentha ndi wothamanga kwambiri womwe umatuluka mu compressor kupita ku evaporator kuti utulutse kutentha ndi kusungunula, ndikulola madzi oundana kulowa mu evaporator ina kuti atenge kutentha ndi kusungunuka kukhala mpweya wotentha ndi wothamanga pang'ono. Bwererani ku compressor suction kuti mumalize kuzungulira. Poganizira kuti kapangidwe kake ka malo osungiramo zinthu zozizira ndi kakuti magawo atatuwa amagwira ntchito pawokha, ngati ma compressor atatuwa agwiritsidwa ntchito limodzi, zigawo zambiri monga mapaipi oyezera pressure, mapaipi oyezera mafuta, ndi ma air header obwerera ziyenera kuwonjezeredwa. Kuvuta kwa zomangamanga ndi kuchuluka kwa uinjiniya sikochepa. Pambuyo pa ziwonetsero ndi kufufuza mobwerezabwereza, pamapeto pake adaganiza zogwiritsa ntchito mfundo yoziziritsa ndi kutentha kwa chipangizo chotenthetsera. Mu dongosolo lokonzanso ili, valavu ya njira zinayi imawonjezedwa kuti ikwaniritse kusintha kwa kayendedwe ka refrigerant panthawi yosungunula malo osungira ozizira. Panthawi yosungunula, kuchuluka kwa refrigerant mu thanki yosungiramo madzi pansi pa condenser kumalowa mu condenser, zomwe zimapangitsa kuti compressor ipange nyundo yamadzi. Valavu yowunikira ndi valavu yowongolera kuthamanga zimawonjezedwa pakati pa condenser ndi thanki yosungiramo madzi. Pambuyo pokonzanso, patatha mwezi umodzi woyeserera, zotsatira zomwe zimayembekezeredwa zimachitika kwathunthu. Pokhapokha ngati chisanu chili chokhuthala kwambiri (chiwerengero cha chisanu chapakati > 10mm), ngati nthawi yosungunula ili mkati mwa mphindi 30, compressor nthawi zina imakhala yofooka. Mwa kufupikitsa kuzungulira kwa kusungunula kwa malo osungira ozizira ndikuwongolera makulidwe a chisanu, kuyeseraku kukuwonetsa kuti bola ngati kusungunula kuli theka la ola patsiku, makulidwe a chisanu sadzapitirira 5mm, ndipo chodabwitsa cha compressor chamadzimadzi chogwedezeka chomwe chatchulidwa pamwambapa sichidzachitika kwenikweni. Pambuyo pokonza zida zosungiramo zinthu zozizira, sizinangothandiza kwambiri ntchito yosungunula zinthu zozizira, komanso zinathandiza kuti chipangizocho chigwire bwino ntchito. Pansi pa mphamvu yosungira yomweyi, nthawi yogwirira ntchito ya chipangizocho yachepa kwambiri poyerekeza ndi kale.
