Yinto eqhelekileyo ukuba ubushushu befriji yesuphamakethi bungakwazi ukwehla kwaye ubushushu buyancipha kancinci. Nantsi uhlalutyo olufutshane lwezizathu zokwehla kobushushu kancinci, ngethemba lokuzisa uncedo kubahlobo abakwishishini elifanayo.
1. Ngenxa yokungasebenzi kakuhle kobushushu okanye ukusebenza kokutywina kwefriji, ukulahleka kwamandla okupholisa kukhulu
Isizathu sokuba ukusebenza kakuhle kokuthintela ubushushu kukuba ubukhulu bomaleko wokuthintela ubushushu kwiipayipi, iibhodi zokuthintela ubushushu, njl. alwanelanga, kwaye isiphumo sokuthintela ubushushu kunye nokugcinwa kobushushu asilunganga. Oku kubangelwa ikakhulu kukukhethwa okungafanelekanga kobukhulu bomaleko wokuthintela ubushushu ngexesha loyilo okanye umgangatho ophantsi wezixhobo zokuthintela ubushushu ngexesha lokwakhiwa. Ukongeza, ngexesha lenkqubo yokwakha, ukuthintela ubushushu kunye nokusebenza okumelana nokufuma kwezinto zokuthintela ubushushu kunokonakala, okubangela ukuba umaleko wokuthintela ubushushu ube manzi, ugogeke, okanye ubole. Esinye isizathu esibalulekileyo sokulahleka okukhulu kokupholisa kukungasebenzi kakuhle kokuthintela ubushushu, kwaye umoya oshushu ngakumbi ungena ngenxa yokuvuza. Ngokubanzi, ukuba kukho ukufuma kumcu wokuvala womnyango okanye isitywina sokuthintela ubushushu sefriji, kuthetha ukuba isitywina asiqinanga. Ukongeza, ukuvulwa rhoqo nokuvalwa kweengcango okanye abantu abaninzi abangena kwindawo yokugcina impahla kunye kuya kwandisa ukulahleka kwamandla okupholisa. Ukuvula ucango kufuneka kuthintelwe kangangoko kunokwenzeka ukuthintela inani elikhulu lomoya oshushu ekungeneni. Kakade ke, xa isitokhwe sithengwa rhoqo okanye ubungakanani obuthengwayo bukhulu kakhulu, umthwalo wobushushu uya kwanda kakhulu, kwaye ngokubanzi kuthatha ixesha elide ukupholisa ukuya kubushushu obuchaziweyo.
2. Iqabaka elikumphezulu we-evaporator lijiyile kakhulu okanye kukho uthuli oluninzi kakhulu, kwaye isiphumo sokudluliselwa kobushushu siyancipha.
Esinye isizathu esibalulekileyo sokwehla kobushushu obucothayo kukusebenza kakuhle kokudlulisa ubushushu kwe-evaporator, okubangelwa kakhulu ngumaleko weqhwa otyebileyo okanye ukuqokelelwa kothuli olugqithisileyo kumphezulu we-evaporator. Ekubeni ubushushu bomphezulu we-evaporator yefriji buphantsi kakhulu kune-0°C, kwaye ukufuma kuphezulu, ukufuma emoyeni kulula ukukuqandisa okanye nokuba kuqande kumphezulu we-evaporator, nto leyo echaphazela isiphumo sokudlulisa ubushushu se-evaporator. Ijiyile kakhulu kumaleko weqhwa womphezulu wesixhobo othintela ukufuma, kufuneka inyibilikiswe rhoqo.
Nazi iindlela ezimbini ezilula zokunyibilikisa:
① Cima ukuze unyibilike. Oko kukuthi, yima icompressor, vula ucango, vumela ubushushu bunyuke, uze uyiqalise kwakhona icompressor emva kokuba umaleko weqabaka unyibilike ngokuzenzekelayo.
②Iqabaka. Emva kokukhupha iimpahla kwifriji, hlambulula umphezulu wombhobho wokukhupha i-evaporator ngqo ngamanzi epompo kubushushu obuphezulu ukuze unyibilikise okanye uwe kumaleko weqabaka. Ukongeza kwisiphumo esibi sokudlulisa ubushushu se-evaporator ngenxa yokuqandisa kakhulu, ukusebenza kakuhle kokudlulisa ubushushu kwe-evaporator kuya kuncipha kakhulu ngenxa yokuqokelelwa kothuli olukhulu kumphezulu we-evaporator ngenxa yokucoca ixesha elide.
3. Kukho umoya omninzi okanye ioyile efrijini kwi-evaporator yefriji yesuphamakethi, kwaye isiphumo sokudlulisa ubushushu siyancitshiswa.
Xa ioyile yefriji iqhotyoshelwe kumphezulu ongaphakathi wetyhubhu yokudlulisa ubushushu ye-evaporator, i-coefficient yayo yokudlulisa ubushushu iya kuncipha. Ngokufanayo, ukuba kukho umoya omninzi kwityhubhu yokudlulisa ubushushu, indawo yokudlulisa ubushushu ye-evaporator iya kuncipha, kwaye i-coefficient yayo yokudlulisa ubushushu nayo iya kwehla kakhulu, kwaye izinga lokuhla kobushushu liya kuncipha ngokufanelekileyo. Ke ngoko, ekusebenzeni nasekugcinweni kwemihla ngemihla, kufuneka kuthathwe ingqalelo ukususa ioyile kumphezulu ongaphakathi wetyhubhu yokudlulisa ubushushu ye-evaporator kwaye kukhutshwe umoya kwi-evaporator ngexesha ukuphucula ukusebenza kakuhle kokudlulisa ubushushu kwe-evaporator.
Ukulungiswa okungafanelekanga okanye ukuvaleka kwevalvu ye-throttle kuya kuchaphazela ngokuthe ngqo ukuhamba kwe-refrigerant kwi-evaporator. Xa ivalvu ye-throttle ivuliwe inkulu kakhulu, izinga lokuhamba kwe-refrigerant likhulu kakhulu, uxinzelelo lokuphuma komphunga kunye nobushushu bokuphuma komphunga nazo ziya kwanda, kwaye izinga lokuhla kobushushu liya kwehla; kwangaxeshanye, xa ivalvu ye-throttle ivuliwe incinci kakhulu okanye ivaliwe, izinga lokuhamba kwe-refrigerant liya kwanda. Amandla okupholisa enkqubo nawo ayancitshiswa, kwaye izinga lokuhla kobushushu kwindawo yokugcina impahla nalo liya kwehla.
Ngokubanzi, kunokugwetywa ukuba izinga lokuhamba kwe-refrigerant yevalvu ye-throttle lifanelekile na ngokujonga uxinzelelo lokuphuma komoya, ubushushu bokufuma kunye nokuqandisa kombhobho wokufunxa. Ukuvaleka kwevalvu ye-throttle yinto ebalulekileyo echaphazela izinga lokuhamba kwe-refrigerant, kwaye izizathu eziphambili zokuvaleka kwevalvu ye-throttle kukuvaleka komkhenkce kunye nokuvaleka okungcolileyo. Ukuvaleka komkhenkce kungenxa yesiphumo esibi sokomisa sesomisi. I-refrigerant iqulethe ukufuma. Xa ihamba ngevalvu ye-throttle, ubushushu buyehla ngaphantsi kwe-0°C, kwaye ukufuma kwi-refrigerant kuyabanda kwaye kuvale umngxuma wevalvu ye-throttle; ukuvaleka okungcolileyo kungenxa yokuqokelelwa kokungcola okuninzi kwisihluzi sokungena sevalvu ye-throttle, ukujikeleza kwe-refrigerant akulunganga, okwenza ukuvaleka.
Ukongeza, ungaxelela abathengi ezinye iindlela zokuzikhusela ekusebenziseni ifriji:
1. Ifriji yokuthutha umgama omde kufuneka ibekwe iiyure ezi-2 ngaphambi kokuba ivulwe ukuze kuthintelwe umonakalo kwinkqubo ngenxa yoxinzelelo olugqithisileyo. Ukusetyenziswa kokuqala, yivumele ikhabhinethi engenanto isebenze iyure e-1, uze ufake izinto xa ubushushu kwikhabhinethi buyehla bufikelele kubushushu obufunekayo kwikhabhinethi.
2. Izinto mazihlulwe xa zifakwa. Ukuba zixinene kakhulu, oko kuya kuchaphazela ukujikeleza komoya opholileyo.
3. Indawo ejikelezileyo yefriji akufuneki ibe kufutshane nomthombo wobushushu, ukuze kuthintelwe ukukhanya kwelanga ngqo kwaye kuchaphazele isiphumo sokupholisa.
4. Ngexesha lenkqubo yokunyibilikisa ngokuzenzekelayo, ubushushu obungaphakathi kwifriji buya kunyuka ngexesha elifutshane. Xa umoya oshushu ongaphandle kwekhabhathi udibana nokutya okunomphezulu obandayo, umbethe uya kujika phezu komphezulu wokutya. Uninzi lombethe luya kususwa xa umatshini uvuliwe ukuze ufrijiwe, kwaye umbethe omncinci uya kuhlala phezu kokutya, into eqhelekileyo.
5. Ivalvu yenaliti ekwi-evaporator yefriji isetyenziselwa uvavanyo lwenkqubo kunye nokuzaliswa kwefriji, kwaye akufuneki ivulwe ngamaxesha aqhelekileyo ukuthintela ukuvuza kwefriji.
6. Isikhenkcezisi asifanele sigcine ulwelo kunye neegesi ezinokutsha, eziqhumayo nezinokutsha.
7. Ulwakhiwo lweshelufu yefriji alunakuthwala ubunzima obungaphezulu kwe-50kg ngemitha yesikwere (kufuneka isasazwe ngokulinganayo), ukuba ininzi kakhulu iya konakalisa ishelufu.
8. Umhlaba akufuneki ube nzulu kwaye kufuneka ugcinwe ulungelelene, kungenjalo uza kuchaphazela ukukhupha amanzi. Ukukhupha amanzi kakubi kuya kuchaphazela ukupholisa okuqhelekileyo kwaye konakalise ifeni.
