Kuyinto evamile yokuthi izinga lokushisa le-supermarket freezer alilahli futhi izinga lokushisa lehla kancane. Manje ngihlaziya kafushane izizathu zokuphonswa kwezinga lokushisa kancane, nginethemba lokuletha usizo kozakwethu emsebenzini.

Isizathu sokuthi kungani ukusebenza kwe-thermal infargation kungukuthi ukushuba kwesendlalelo sokufakwa kwamapayipi okushisayo, amabhodi wokufaka okufakwayo, njll. Akwanele, futhi umphumela wokufakelwa okushisayo kanye nokufakelwa okushisayo akukuhle. Kubangelwa ikakhulukazi ukukhethwa okungafanele kokukhuluphawa kwesendlalelo sokufakwa kwe-thermal ngesikhathi sokuklama noma ikhwalithi engemihle yezinto zokwakha ezishisayo ngesikhathi sokwakha. . Ngaphezu kwalokho, enqubweni yokwakhiwa, ukufakwa kwe-thermal kanye nokusebenza kofakazi bobufakazi be-thermal yokufakelwa kwezinto ezishisayo kungalimala, okuholela engxenyeni yokufakelwa okushisayo kube ngamanzi, akhubazekile, noma aqede. Esinye isizathu esibalulekile sokulahleka okukhulu kokupholisa ukukwenza uphawu lokubopha uphawu, kanye nomoya oshisayo ovuzayo kusuka ekuvuzeni. Ngokuvamile, uma ukuguqulwa kwenzeka emgqeni wokubopha uphawu lomnyango noma uphawu lokuvikelwa kokushisa kwefriji, kusho ukuthi uphawu lungaqinile. Ngaphezu kwalokho, ukuvula okujwayelekile nokuvalwa kweminyango noma abantu abaningi abangena endaweni yokugcina izimpahla ndawonye bazokhulisa nokulahlekelwa ukupholisa. Ukuvula umnyango kufanele kugwenywe ngangokunokwenzeka ukuvikela inani elikhulu lomoya oshisayo kusuka ekungeneni. Vele, lapho isitoko sivame ukuthengwa noma isitoko sikhulu kakhulu, umthwalo wokushisa ukhuphuka kakhulu, futhi ngokuvamile kuthatha isikhathi eside ukupholisa okushisa okucacisiwe.
2. Isithwathwa ebusweni se-evaporator simikhulu kakhulu noma kunothuli oluningi kakhulu, futhi umphumela wokudlulisa ukushisa uncishisiwe
Esinye isizathu esibalulekile sokudonswa kwamazinga okushisa okuhamba kancane kungukusebenza okuphansi kokushisa okuphansi kokuhlelwa kwe-evaporator, okubangelwa ikakhulukazi i-frest urler noma ukunqwabelana ngokweqile kothuli emphemeni we-evaporator. Ngoba izinga lokushisa elingaphezulu le-freezer evaporator liphansi kakhulu kune-0 ° C, futhi umswakama osezingeni eliphakeme, umswakama osemoyeni uqhwa kalula noma ugcwele phezulu komphumela we-evaporator, okuthinta umphumela wokudluliswa kokushisa komkhathi. Ukuze uvikele isendlalelo seqhwa seqhwa somkhumbi ukuba ungabi namandla kakhulu, kudingeka ahlulwe njalo.
Nazi izindlela ezimbili ezilula ze-defrosting:
① Yima ukuze u-defrost. Lokho wukuthi, yeka i-compressor, vula umnyango, vumela izinga lokushisa likhuphuke, futhi liqale kabusha i-compressor ngemuva kokuhlelwa kwesithwathwa.
Ukhilimu we-②chong. Ngemuva kokususa izimpahla efrijini, hlambulula ngokuqondile ingaphezulu lepayipi le-evaporator ekhishwe ngamanzi ompompi ngamazinga okushisa aphezulu ukuze uchithe noma uwe ungqimba lwesithwathwa. Ngaphezu komphumela wokudluliswa kokushisa ompofu we-evaporator ngenxa yesithwathwa esiwugqinsi, ukusebenza kahle kokushisa kwe-evaporator kuzoncishiswa kakhulu ngenxa yokuqongelelwa kothuli ngokweqile ebusweni be-evaporator ngoba akuhlanzwa isikhathi eside.
I-3. Kunomoya omningi womoya noma amafutha esiqandisini ku-evaporator of the supermarket freezer, futhi umphumela wokudlulisa ukushisa uncishisiwe
Lapho nje uwoyela wefriji amaningi unamathiselwe endaweni yangaphakathi ye-tube yokudlulisa ukushisa komshini we-evaporator, i-coeffection yayo yokudlulisa ukushisa izokwehla. Ngokufanayo, uma kunomoya owengeziwe ku-tube yokudluliswa kokushisa, indawo yokudlulisa ukushisa komhwamuko izoncishiswa, futhi ukudluliswa kwayo kokushisa kuzoncishiswa. Ukusebenza kahle kuzokwehla kakhulu, futhi izinga lokushisa lokushisa lizoncipha. Ngakho-ke, ekusebenzeni kwansuku zonke nasekulungisweni, ukunakwa kufanele kukhokhwe ekususweni okufika ngesikhathi kwamabala kawoyela endaweni yangaphakathi ye-Evaporator Heat Transfer Tube futhi ukhiphe umoya ku-Evaporator ukuze uthuthukise ukusebenza kahle kokushisa komkhathi.
I-4. I-throttle valve ilungiswa ngokungafanele noma ivinjiwe, futhi ukugeleza okuqandayo kukhulu kakhulu noma kuncane kakhulu
Ukulungiswa okungafanele noma ukuguquguquka kwe-throttle valve kuzothinta ngqo ukugeleza kwesiqandisi Lapho i-throttle valve ivulwa inkulu kakhulu, isilinganiso sokugeleza esiqandisi sikhulu kakhulu, ingcindezi yokuhwamuka kanye nokushisa okuguqukayo kuyanda, futhi izinga lokulahla lokushisa lizokwehlisa ijubane; Ngasikhathi sinye, lapho i-throttle valve ivulwa incane kakhulu noma ivinjiwe, isilinganiso sokugeleza esiqandisini lapho umthamo opholile wohlelo naye uncishisiwe, futhi izinga lokushisa lendawo yokugcina izinto lizoncipha.
Ngokuvamile, kungahlulelwa ukuthi isilinganiso sokuhamba esiqandisi se-throttle valve kufanelekile ngokubheka ingcindezi yokuhwamuka, ukuhwamuka kwamazinga okushisa kanye nesimo seqhwa sepayipi lokumunca. Ukuvinjelwa kwe-throttle valve kuyisici esibalulekile esithinta ukugeleza kwesiqandisi. Izizathu eziphambili zokuvinjelwa kwe-throttle valve kungukuqhekeka kweqhwa nokuvinjelwa okungcolile. I-Ice Blockage kungenxa yomphumela owomileyo ongemuhle we-dryer, futhi esiqandisini siqukethe umswakama. Lapho igeleza i-throttle valve, izinga lokushisa lehla ngaphansi kuka-0 ° C, kanye nomswakama osefriji efrijini ungene eqhweni bese uvimba umgodi we-throttle valve; Ukuqhekeka okungcolile kungenxa yokuqongelelwa kokungcola okwengeziwe esikrinini sokuhlunga endaweni yokungena kwe-throttle valve, ukugeleza kwesiqandisi akubushelelezi, okuholela ekuqhekekeni.
Izindlela zokuphepha zokusebenzisa i-freezer:
1. Ifriji yokuhamba ibanga elide kufanele ibekwe amahora ama-2 ngaphambi kokuthi inikezwe amandla ukuvikela uhlelo ukuthi lulinyazwe ngenxa yengcindezi eyeqile. Ngokusetshenziswa kokuqala, vumela ikhabethe elingenalutho lisebenzele ihora eli-1, lapho izinga lokushisa elisebhokisini liya emazingeni okushisa adingekayo kwikhabethe, bese lifaka izinto.
2. Izinto kufanele zihlukaniswe lapho zifakwa. Izinsimbi eziqinile kakhulu zizothinta ukujikeleza komoya.
I-3. Ifriti akufanele isondele emthonjeni wokushisa ukuze igweme ukukhanya kwelanga okuqondile futhi kuthinte umphumela wokupholisa.
4. Ngesikhathi senqubo yokuzenzakalelayo ye-freezer, izinga lokushisa kwikhabethe lizophuma esikhathini esifushane. Lapho umoya oshisayo ngaphandle kweKhabhinethi uhlangabezana nokudla endaweni ebandayo, ingaphezulu kokudla kuzokususwa, futhi iningi lamazolo lizosuswa lapho isiqandiso sivulwa, futhi inani elincane lamazolo lizohlala ekudleni, okuyinto ejwayelekile.

7. Ukwakheka kweshalofini kwe-freezer kungathwala isisindo esingadluli ku-50kg ngemitha yesikwele (kudinga ukusatshalaliswa ngokulinganayo), futhi okuningi kuzolimaza amashalofu.
8. Umhlabathi akufanele ube nezikhathi futhi kufanele ugcinwe izinga, ngaphandle kwalokho kuzothinta ukudonsa, futhi ukudonsa okungalungile kuzothinta ukupholisa okujwayelekile nokwenza umonakalo omkhulu.
