Esinye isizathu esibalulekile sehla kancane lokushisa kwesitoreji kungukusebenza okuphansi kokushisa okuphansi komkhathi, okubangelwa ikakhulu ukunqwabelana kwesithwathwa kwesithwathwa. Njengoba izinga lokushisa elingaphezulu komkhumbi esiqongweni esibandayo liphansi kakhulu kune-0 ℃, futhi umswakama osendaweni yokugcina impahla uphakeme, umswakama emoyeni kalula, othinta iqhwa ebusweni be-evaporator, ethinta umphumela wokudluliswa kokushisa komkhathi. Ukuze uvikele isendlalelo seqhwa seqhwa somkhumbi ukuba ungabi namandla kakhulu, kudingeka ahlulwe njalo. Izindlela ezimbili ezilula ze-defrosting zethulwa ngezansi: ① Stop Defrosting. Okusho ukuthi, yeka ukusebenza kwe-compressor, vula umnyango we-warehouse, vumela izinga lokushisa lendawo yokugcina izimpahla, bese uqala kabusha i-compressor ngemuva kokuncipha kwesithwathwa. ② geza ukhilimu. Ngemuva kokuhambisa izimpahla ngaphandle kwendawo yokugcina izimpahla, hlambulula ngokuqondile ingaphezulu lepayipi le-evaporator ngamanzi ompompi anamazinga okushisa aphezulu ukuze ancibilike noma awele 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.

Ukusebenza kwe-infration okumpofu kungenxa yokubhema okunganele kongqimba lokufakwa kwamapayipi okushisayo kanye nezindonga zokufaka okushisayo okushisayo, kanye nokufakelwa okushisayo okushisayo kanye nomphumela wokufakelwa okushisayo. Kubangelwa ikakhulukazi ukukhethwa okungafanele kokukhuluphawa kwesendlalelo sokufakwa kwe-thermal ngesikhathi sokuklama noma ikhwalithi engemihle yezinto zokwakha ezishisayo ngesikhathi sokwakha. Ngaphezu kwalokho, kwinqubo yokwakhiwa nokusetshenziswa, ukufakwa kwe-thermal kanye nokusebenza kobufakazi bobufakazi bezinto ezibonakalayo zokufakwa okushisayo kungalimala, okuholela ekuhlolweni okushisayo okushisayo kube ngamanzi, akhubazekile, noma afezeke. yehlisa kancane ijubane. Esinye isizathu esibalulekile sokulahleka okukhulu kokupholisa ukuncipha kokufakwa uphawu okumpofu kwendawo yokugcina izinto, kanye nomoya oshisayo ovuthayo ungene endaweni yokugcina izinto. Ngokuvamile, uma kunokwedlulela emgqeni wokubopha uphawu lomnyango we-warehouse noma uphawu lodonga lokugcina olubandayo lokugcina, kusho ukuthi ukubekwa uphawu akuqinile. Ngaphezu kwalokho, ukuvulwa okujwayelekile nokuvalwa komnyango we-warehouse noma abantu abaningi abangena endaweni yokugcina izimpahla ndawonye bazokhulisa nokulahleka kwamandla okupholisa esitolo sokugcina. Gwema ukuvula umnyango we-Warehouse ngangokunokwenzeka ukuvimbela inani elikhulu lomoya oshisayo ungangeni esitolo. Kuyiqiniso, lapho indawo yokugcina izinto ivame ukugcwaliswa noma isitoko sikhulu kakhulu, umthwalo wokushisa ukhulisa kakhulu, futhi ngokuvamile kuthatha isikhathi eside ukupholisa okushisa okucacisiwe.
I-3. 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 okuqandayo ku-everator. Lapho i-throttle valve ivulwa inkulu kakhulu, isilinganiso sokugeleza esiqandisi sikhulu kakhulu, ukufuthelwa kwengcindezi yokuhwamuka kanye nokushisa okuguqukayo kuzokhula, futhi izinga lokushisa lokushisa lizokwehlisa ijubane; Ngasikhathi sinye, lapho kuvulwa i-throttle valve encane kakhulu noma ivinjiwe, isiqandisi sokugeleza futhi sincishisiwe, umthamo wokupholisa wohlelo futhi uncishisiwe, futhi izinga lokushisa lokushisa lincishisiwe, futhi izinga lokushisa lokushisa 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.
4. Ukusebenza kahle kwe-compressionar compressor kuphansi, futhi amandla apholile awakwazi ukubhekana nezidingo zomthwalo ze-warehouse
Ngenxa yokusebenza isikhathi eside kwe-compressor yefriji, i-cylinder liner kanye nendandatho ye-piston nezinye izingxenye zigqokwa ngokuqinile, futhi ukucaciswa kokuqhathanisa kuzokwehla, amandla okuhambisa uphawu azokwehla, futhi amandla apholile ancipha. Lapho umthamo wokupholisa ungaphansi komthwalo wokushisa we-warehouse, izinga lokushisa lesilondolozi lizokwehla kancane. Umthamo wesiqandisi we-compressor ungahlulelwa cishe ngokubheka ukucindezela kokumunca nokukhipha kwe-compressor. Uma umthamo wefriji we-compressor wehla, indlela esetshenziswa kakhulu ukufaka esikhundleni se-cylinder liner ne-piston ring ye-compressor. Uma ukushintshwa kusasebenza, ezinye izinto kufanele zibhekwe, noma zisatshalaliswe futhi ziguqule, futhi zixazulule inkinga.

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 lokuphonsa kokushisa kwama-warehouse lizokwehlisa ijubane. 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-6. Inani lesiqandisi elisesistimu alwanele, futhi amandla apholile awanele
Kunezizathu ezimbili eziyinhloko zokujikeleza okunganele esiqandisini. Okokuqala, inkokhiso eqandekile ayanele. Ngalesi sikhathi, inani elanele lesiqandisi esidinga ukungezwa. Esinye isizathu ukuthi kunezikhathi eziningi zokuvuza esigamekweni. Kulokhu, kufanele uqale uthole iphuzu lokuvuza, gxila ekubhekeni ukuxhumeka kwepayipi ngalinye ne-valve, bese ugcwalisa inani elanele lesiqandisi ngemuva kokulungisa izingxenye ezivuthiwe ngemuva kokulungisa izingxenye ezivuthiwe.
