Umthamo wefriji awukwazi ukuhlangabezana neemfuno zomthwalo wedepho (ukusebenza kakuhle kwecompressor ephantsi)
Kukho izizathu ezibini eziphambili zokunqongophala kobuninzi bokujikeleza kwefriji. 
Enye kukuba intlawulo yefriji ayanelanga, ngeli xesha, kufuneka nje uzalise inani elaneleyo lefriji;
Esinye isizathu kukuba kukho ukuvuza okuninzi kwe-refrigerant kwinkqubo, kule meko, kufuneka siqale sifumane ukuvuza, sigxile ekujongeni uqhagamshelo lwepayipi kunye neevalvu, sifumanise ukuvuza size sikulungise, size emva koko sihlawulise inani elaneleyo le-refrigerant.
Ukungabikho komthamo wokufaka ifriji (ubuninzi befriji engonelanga kwinkqubo)
Ubungakanani obungonelanga be-refrigerant kwinkqubo buya kuyichaphazela ngokuthe ngqo indlela ye-refrigerant eya kwi-evaporator. Xa i-expansion valve ivuleka kakhulu, i-expansion valve ayilungiswanga kakuhle okanye ayivalwanga. Xa i-refrigerant flow inkulu, uxinzelelo lwe-evaporation kunye nobushushu be-evaporation buya kunyuka, kwaye ukwehla kobushushu be-warehouse kuya kuncitshiswa; okwangoku, xa i-expansion valve incinci kakhulu okanye ivalwa, ukuhamba kwe-refrigerant kuya kuncitshiswa, kwaye amandla e-refrigerant yenkqubo aya kuncitshiswa, kwaye ukwehla kobushushu be-warehouse nako kuya kuncitshiswa. Ngokubanzi, singabona uxinzelelo lwe-evaporation, ubushushu be-evaporation kunye ne-frost yombhobho wokufunxa ukuze sibone ukuba ukuhamba kwe-refrigerant ye-expansion valve kufanelekile na. Ukuvaleka kwe-expansion valve yinto ebalulekileyo echaphazela ukuhamba kwe-refrigerant, kwaye izizathu eziphambili zokuvaleka kwe-expansion valve kukuvaleka komkhenkce kunye nokuvaleka okungcolileyo. Ukuvaleka komkhenkce kungenxa yokuba isiphumo sokomisa somileyo asilungile, i-refrigerant inamanzi, kwaye xa ihamba nge-expansion valve, ubushushu buyehla bube ngaphantsi kwe-0.℃, amanzi akwi-refrigerant aya kuba ngumkhenkce aze avale umngxuma wevalvu yomphunga; ukuvaleka okungcolileyo kungenxa yokuba isihluzo sokungena sevalvu yokwandisa sinokungcola okuninzi, kwaye i-refrigerant ayihambi kakuhle, nto leyo eyenza ukuvaleka.
Ukuhamba kwefriji kukhulu kakhulu okanye kuncinci kakhulu (ivalvu yokwandisa elungisiweyo okanye evalekileyo ngendlela engafanelekanga)
I-coefficient yayo yokudlulisa ubushushu iya kuncitshiswa, xa ityhubhu yokudlulisa ubushushu ye-evaporator ineoyile engakumbi yefriji enamathele kwimbonakalo yayo yangaphakathi. Ngokufanayo, ukuba kukho umoya omninzi kwityhubhu yokudlulisa ubushushu, indawo yokudlulisa ubushushu ye-evaporator iyancitshiswa, kwaye ukusebenza kwayo kokudlulisa ubushushu kuya kuncitshiswa kakhulu, kwaye ubushushu begumbi lokugcina buyancipha. Ke ngoko, ukusebenza kwemihla ngemihla kunye nokugcinwa, kufuneka kuthathelwe ingqalelo ekucoceni ngexesha elifanelekileyo ityhubhu yokudlulisa ubushushu ye-evaporator ngaphakathi kwembonakalo yeoyile kwaye kukhutshwe umoya kwi-evaporator, ukuze kuphuculwe ukusebenza kokudlulisa ubushushu ye-evaporator.
Isiphumo sokudluliselwa kobushushu siyancipha (i-evaporator xa kukho umoya omninzi okanye ioyile eqandisayo)
Oku kungenxa yokuba umaleko weqabaka yangaphandle ye-evaporator utyebile kakhulu okanye uthuli oluninzi kakhulu olubangelwa yindawo ebandayo yokubeka ubushushu bangaphandle be-evaporator buphantsi kakhulu kune-0℃, nto leyo ebangela esinye isizathu esibalulekileyo sokwehla kancinci kobushushu bethala leencwadi kukuba ukusebenza kakuhle kokudluliselwa kobushushu kwi-evaporator kuphantsi. Kwaye ukufuma kwendawo yokugcina impahla kuphezulu, ukufuma emoyeni kulula kakhulu ukukuqandisa ngaphandle kwe-evaporator, kwanomkhenkce, okuchaphazela isiphumo sokudluliselwa kobushushu se-evaporator. Ukuze kuthintelwe ukuba umaleko weqabaka yangaphandle ye-evaporator ube mkhulu kakhulu, kufuneka unyibilikiswe rhoqo.
Nazi iindlela ezimbini ezilula zokunyibilikisa:
①yeka ukunyibilikisa iqabaka. Oko kukuthi, yeka ukusebenza kwecompressor, vula ucango, vumela ubushushu bethala leencwadi bunyuke, ukuze bunyibilike ngokuzenzekelayo, uze uqalise kwakhona icompressor.
②Ukukhuhla iqabaka. Emva kokukhupha iimpahla kwindawo yokugcina impahla, hlamba ngokuthe ngqo umphezulu wetyhubhu yomqolo we-evaporator ngamanzi ompompo obushushu obuphezulu ukuze umaleko weqabaka unyibilike okanye uwe. Ukongeza kwiqabaka elityebileyo kakhulu kuya kukhokelela ekubeni isiphumo sokudlulisa ubushushu be-evaporator asilunganga, ukubonakala kwe-evaporator ngenxa yokungacocwa okwethutyana kunye nokuqokelelwa kothuli kukhulu kakhulu, ukusebenza kwayo kokudlulisa ubushushu kuya kuncipha kakhulu.
Isiphumo sokudluliselwa kobushushu siyancipha (iqabaka yangaphandle ye-evaporator ityebile kakhulu okanye iqokelela uthuli oluninzi kakhulu)
Isiphumo sokuthintela ubushushu kunye nokuthintela ubushushu asisihle, umsebenzi wokuthintela ubushushu awulunganga kungenxa yokuba ubukhulu bomaleko wokuthintela ubushushu bombhobho, udonga lokuthintela ubushushu lwendlu yokugcina impahla, njl. alwanelanga. Oku kubangelwa ikakhulu kukukhetha okungafanelekanga kobukhulu bomaleko wokuthintela ubushushu xa kusenziwa okanye umgangatho ophantsi wezinto zokuthintela ubushushu xa kusakhiwa.
Ukongeza, inkqubo yokwakha nokusetyenziswa, umsebenzi wokukhusela ukufuma kwezinto zokugquma ungonakaliswa nto leyo ebangela ukufuma komaleko wokugquma, ukuguqulwa, kwanokubola, amandla ayo okugquma kunye nokukhusela ayancipha, ithala leencwadi ngokuchasene nokulahleka kwengqele liyakhula, ukwehla kobushushu kwithala leencwadi kuyehla kakhulu.
Esinye isizathu esibalulekileyo sokulahlekelwa yingqele kukungavali kakuhle kwendlu yokugcina impahla, kukho umoya oshushu ngakumbi ovela emoyeni ovuzayo ungene kwindawo yokugcina impahla. Ngokubanzi, ukuba itywina lomnyango okanye indawo yokugcina izinto ezibandayo itywina udonga xa itywina liqina, oko kuthetha ukuba itywina aliqinanga.
Ukongeza, ukuvulwa nokuvalwa rhoqo kocango okanye abantu abaninzi abangena kunye kwindawo yokugcina impahla kuya kwandisa ukulahleka kwendawo yokugcina ebandayo. Kufuneka uzame ukuthintela ukuvula ucango ukuze kuthintelwe umoya oshushu omninzi kwindawo yokugcina impahla. Kakade ke, indawo yokugcina impahla ingena rhoqo okanye kwisitokhwe mkhulu kakhulu, umthwalo wobushushu uyanda kakhulu, ukuze uphole uye kubushushu obucacileyo kudla ngokuthatha ixesha elide.
Oku kubangela ukulahleka okukhulu kwengqele (indawo yokugcina ebanda ngenxa yokungasebenzi kakuhle kwe-insulation okanye umsebenzi wokuyivala)
I-cylinder liner kunye ne-piston ring kunye nezinye iindawo ngenxa yokuguga okukhulu, i-compressor ngenxa yokusebenza okwethutyana. Xa indawo ivuliwe, umsebenzi wokutywina uya kuncipha ngokufanayo, i-coefficient yokuhambisa umoya ye-compressor nayo iyancitshiswa, amandla okukhenkceza aya kuncipha. Xa amandla okuphola engaphantsi komthwalo wobushushu we-warehouse, kuya kukhokelela ekwehleni kancinci kobushushu be-warehouse. Ingabonwa ngokujonga uxinzelelo lokufunxa kunye nokukhupha i-compressor luqikelela ubungakanani be-friji ye-compressor. Ukuba amandla okuphola e-compressor ayancipha, indlela eqhelekileyo kukutshintsha i-compressor cylinder sleeve kunye ne-piston ring, ukuba ukutshintshwa akusebenzi, kufuneka kuqwalaselwe ezinye izinto, kwaye kususwe umatshini ukuze kuvavanywe, ukuze kukhutshwe izinto ezingalunganga.
