Kuyinto evamile yokuthi izinga lokushisa le-supermarket freezer alikwazi ukwehla futhi izinga lokushisa lehla kancane. Nakhu ukuhlaziywa kafushane kwezizathu zokuphonswa kwezinga lokushisa kancane, ngethemba lokuletha usizo kubangane embonini efanayo.

Isizathu esenza ukuthi ukusebenza kokufudumala kwe-Insulation kumpofu ukuthi ubukhulu bomenyu wokufakelwa kwamapayipi, amabhodi wokufaka ukushisa, njll. Akwanele, futhi umphumela wokuvikelwa kokushisa nokulondolozwa kokushisa akukuhle. Kubangelwa ikakhulukazi ukukhethwa okungafanele kokukhuluphawa kongqimba wokufakelwa ngesikhathi sokuklama noma ikhwalithi engeyinhle yezinto zokwakha ngesikhathi sokwakha. . Ngaphezu kwalokho, ngesikhathi sokwakha, ukufakwa kwe-thermal kanye nokusebenza komswakama - ubufakazi bezinto zokufaka umswakama bungalimala, kubangele ungqimba lokufakelwa okushisayo kube ngamanzi, akhubazekile, noma afezeke. Esinye isizathu esibalulekile sokulahleka okukhulu kokupholisa ukukwenza kahle ukubekwa uphawu, kanye nomoya oshisayo oshisayo kusuka ekuvuzeni. Ngokuvamile, uma kunokwedlulela emgqeni wokubopha uphawu lomnyango noma uphawu lokuvikelwa kokushisa kwesiqandisi, kusho ukuthi uphawu lungaqinile. Ngaphezu kwalokho, ukuvula okujwayelekile nokuvalwa kweminyango noma abantu abaningi abangena endaweni yokugcina izinto ndawonye bazokhulisa nokulahleka kwamandla okupholisa. Ukuvula umnyango kufanele kugwenywe ngangokunokwenzeka ukuvikela inani elikhulu lomoya oshisayo kusuka ekungeneni. Vele, lapho isitoko sithengwa kaningi noma inani elithengiwe likhulu kakhulu, umthwalo wokushisa uzonyusa kakhulu, futhi ngokuvamile kuthatha isikhathi eside ukupholisa amazinga okushisa acacisiwe.

Esinye isizathu esibalulekile sokudonswa kwamazinga okushisa okuhamba kancane kungukusebenza kahle kokushisa okushisayo kwe-evaporator, okubangelwa ikakhulukazi yi-frest ungqimba noma ukunqwabelana uthuli ngokweqile ebusweni bomfanekiso. Njengoba izinga lokushisa elingaphezulu kwesiqandisi sefriji sefriji liphansi kakhulu kune-0 ° C, futhi umswakama ophakeme, umswakama osemoyeni kulula kakhulu ukuthwala noma ukhulula umthombo wokudluliswa kokushisa komkhathi. Ubukhulu kakhulu ngesendlalelo seqhwa sedivayisi evimbela ukuhwamuka, dinga njalo ukuthi kufanele ihlulwe.
Nazi izindlela ezimbili ezilula ze-defrosting:
① vala phansi ukuze u-defrost. Lokho wukuthi, yeka i-compressor, vula umnyango, vumela izinga lokushisa likhuphuke, futhi liqale kabusha i-compressor ngemuva kokuhlelwa kwesithwathwa.
②fst. Ngemuva kokuhambisa izimpahla ngaphandle kwefriji, hlamba ingaphezulu lepayipi eligcwele i-evaporator ngqo ngamanzi ompompi endaweni yokushisa ephakeme ukuze uchithe noma uwe ungqimba lwesithwathwa. In addition to the poor heat transfer effect of the evaporator due to too thick frosting, the heat transfer efficiency of the evaporator will also be significantly reduced due to the thick dust accumulation on the surface of the evaporator due to long-term cleaning.
I-3. Kunomoya omningi noma amafutha esiqandisi esiqandisiwe ku-evaporator we-supermarket freezer, futhi umphumela wokudlulisa ukushisa uncishisiwe
Lapho nje uwoyela esiqandisi futhi unamathiselwe endaweni yangaphakathi ye-tube yokudluliswa kokushisa ye-evaporator, i-coeffection yayo yokudlulisa ukushisa izokwehla. Ngokufanayo, uma kunomoya owengeziwe ku-tube yokudluliswa kokushisa, indawo yokudluliswa kokushisa ye-evaporator izokwehla, futhi ukusebenza kwawo kokufudukela kwawo kuzokwehla kakhulu, futhi izinga lokushisa lokushisa lizokwehlisa ngokufanele. Ngakho-ke, ekusebenzeni kwansuku zonke nasekulungiseni, ukunakekelwa kufanele kuthathwe ukususa uwoyela endaweni yangaphakathi yokushisa okushisayo kwe-evaporator yokudlulisa ishubhu futhi kukhiphe umoya ku-evaporator ngesikhathi ukuze uthuthukise ukusebenza kahle kokushisa komkhathi.
Ukulungiswa okungafanele noma ukuguquguquka kwe-throttle valve kuzothinta ngqo ukugeleza okuqandayo ku-everator. Lapho i-throttle valve ivulwa inkulu kakhulu, isilinganiso sokugeleza esiqandisi sikhulu kakhulu, izinga lokushisa lokuhwamuka nokuhwamuka lizokhula futhi, futhi izinga lokulahla lokushisa lizokwehlisa ijubane; Ngasikhathi sinye, lapho i-throttle valve ivulwa incane kakhulu noma ivinjiwe, isilinganiso sokugeleza esiqandisi esiqandayo sizokwanda. Umthamo opholile wohlelo futhi uncishisiwe, futhi izinga lokushisa lokushisa le-warehouse lizophinde yehlise ijubane.
Ngokuvamile, kungahlulelwa ukuthi isilinganiso sokuhamba esiqandisini se-throttle valve kufanelekile ngokubuka ingcindezi yokuhwamuka, izinga lokushisa lokuhwamuka kanye nokuqalwa kwepayipi lokumunca. I-Throttle Valve Blockage iyinto ebalulekile ethinta isilinganiso sokugeleza esiqandisini, kanye nezimbangela eziphambili zeThrottle Valve Blockage kukhona ukuvaleka kweqhwa nokuvinjwa okungcolile. I-Ice Blockage kungenxa yomphumela owomile okomileyo we-dryer. Isiqandisi siqukethe umswakama. Lapho igeleza i-throttle valve, izinga lokushisa lehla ngaphansi kuka-0 ° C, kanye nomswakama osefrijini enkabeni futhi uvimbele umgodi we-throttle valve; Ukuvinjwa okungcolile kungenxa yokuqongelelwa kokungcola okwengeziwe esihlangelini se-inlet ye-throttle valve, ukusakazwa kwesiqandisi akubushelelezi, kwakha i-blockage.
Ngaphezu kwalokho, futhi ungatshela amakhasimende ezinye izindlela zokusebenzisa i-freezer:
1. I-freezer yokuhamba ibanga elide kufanele ibekwe amahora ama-2 ngaphambi kokuthi inikezwe amandla ukuvikela ukulimala kohlelo ngenxa yengcindezi eyeqile ngenxa yengcindezi eyeqile. Ngokusetshenziswa kokuqala, vumela iKhabhinethi engenalutho isebenze ihora eli-1, bese ibeka izinto lapho izinga lokushisa kwiKhabhinethi liyehla emazingeni okushisa adingekayo kwikhabhinethi.
2. Izinto kufanele zihlukaniswe lapho zifakwa. Uma zigcwele kakhulu, kuzothinta ukusakazwa komoya.
I-3. Indawo ezungezile ye-freezer akufanele isondele emthonjeni wokushisa, ukuze igweme ukukhanya kwelanga okuqondile futhi kuthinte umphumela wokupholisa.
4. Ngesikhathi senqubo yokuzenzakalelayo ye-Defrosting, izinga lokushisa ngaphakathi kwefriji lizokhuphuka esikhathini esifushane. Lapho umoya oshisayo ngaphandle kwekhabethe uhlangabezana nokudla okubandayo, amazolo azowazula ebusweni bokudla. Iningi lamazolo lizosuswa lapho umshini uvulwa ukuze uthole isiqandisi, futhi inani elincane lamazolo asazohlala ekudleni, okuyinto evamile.

7. Ukwakheka kweshalofini kwe-freezer kungakwazi ukuthwala ngaphezu kwe-50kg yesisindo ngemitha yesikwele ngasinye (kudingeka ukuthi kusatshalaliswe ngokulinganayo), okuningi kuzolimaza ishelufu.
8. Umhlabathi akufanele ube nezikhathi zokungezelela futhi kufanele ugcinwe izinga, ngaphandle kwalokho kuzothinta ama-drainage. Ukudonsa okungalungile kuzothinta ukupholisa okujwayelekile nokulimaza i-fan.
