Ubushushu bompompo we-compressor yefriji bubhekisa kwi-valve yokukhupha kwiqondo lobushushu le-refrigerant, ukuqinisekisa ukusebenza ngokukhuselekileyo kwe-compressor, amalungiselelo obushushu bompompo wesixhobo se-R12 awakwazi ukudlula i-130℃, ii-R22 kunye neenkqubo ze-ammonia azinakudlula i-50℃. Ubushushu bomphunga buphezulu kakhulu, nto leyo eya kubangela ukuba ioyile yokuthambisa inciphise i-viscosity ngenxa yokunyuka kobushushu, kwaye yenze isiphumo sokuthambisa sibe sibi, nto leyo eya kubangela ukuba iindawo ezisebenzayo zonakale ngokulula. Xa ubushushu bomphunga bunyuka kufutshane nendawo yokutsha ye-lubricant, akulula ukuba yingozi, kwaye ubushushu bomphunga buphezulu kakhulu kunobushushu bokujiya.
Ubushushu bekhabhinethi ebandayo buphezulu kwiimeko ezimbini: Okokuqala, i-fluorine evuzayo efrijini kwaye akukho khabhinethi ebandayo efrijini ebisebenza, kodwa ubushushu obungaphakathi kwekhabhinethi abunakuncipha. Ixesha elide kakhulu, ukulahleka kokutya ngaphakathi kwekhabhinethi kubi kakhulu, nceda uyilungise ngexesha langempela iya kuba njalo. Njengesiqhelo, ayisiyofriji entsha nje kuphela, kodwa ngokuqhelekileyo kwigumbi elibandayo eliphakathi kweqabaka ukukunika olu luvo luhlala lucotha kakhulu. Elinye icala alinaqabaka kwaye lityebile kwicala leqabaka. Ifriji ayikhe yaqabaka ixesha elide. Ngeli xesha, kunokubakho amanqaku ambalwa ebhalbhu yamanzi abonakalayo, ubushushu obungaphakathi kwekhabhinethi buphezulu.
Ifriji enjalo idla ngokuba nzima ukuyilungisa. Kunzima ukufumana ukuvuza ixesha elide emva kokulungiswa kuba kunzima ukufumana ukuvuza. Isizathu sesibini sobushushu obuphezulu yi-evaporator frost, le meko ikakhulu zii-freezers ezipholisiweyo ngumoya, olu hlobo lwefriji lufuna i-evaporator, ukuba ayikuko ukulahleka kweqhwa kule evaporator, iya kuvala indlela yomoya. Umkhuhlane awuyi kukhutshwa kwaye i-freezer ayinakupholiswa. Le meko isenokuba ngenxa yengxaki yenkqubo yokunyibilikisa okanye ngenxa yokuba i-defrost timer inempazamo okanye ityhubhu yokufudumeza yonakele.
1. I-compressor ayizukuqalisa
Ukuba akukho mbane kwifriji kwaye isibane sesalathisi sangaphakathi sinokuvula, ungaluvala ucango lwefriji. Ukuba ifriji ithi kukho umbane, ukuba isibane asikhanyi, jonga ukuba umbane oyintloko uvuliwe uze uqinisekise ukuba ifuse yefriji ayisiyo yonke ifriji. Ngaba kukho ingxaki ngokudibana kwe-thermostat?
2. I-compressor isenokutsha, i-motor coil itsha, kwaye i-starter ingajongwa. Xa isikhuselo sobushushu obugqithisileyo sisebenza, kufuneka ulinde ixesha elithile ukuze ubushushu be-compressor buqale ukwehla.
3. Ingxaki yenzeka kuba i-thermostat ayinakusetwa kwakhona, kuba oonxibelelwano badibene kwaye abanakwahlulwa.
3. Iqabaka elingaphakathi kwifriji likhulu kakhulu kwaye ukumelana nobushushu kukhulu, nto leyo echaphazela ukuqhutywa komoya obandayo.
4, ifriji ayibekwanga kakuhle okanye ukuqokelelana kothuthu lwe-condenser kukhulu kakhulu, nto leyo echaphazela ukusasazwa kobushushu be-condenser.
5, itshaja yenkqubo yokufriji ininzi kakhulu, umthwalo womsebenzi wecompressor unzima, i-condenser ishushu kwicala eliphezulu, icala elingezantsi lisondele kubushushu begumbi. Itshaja yefriji eninzi kakhulu ebangelwe kwi-evaporator ayinakupheliswa ngokupheleleyo, nto leyo ebangela ukuba amandla okupholisa e-evaporator ehle, ukuba i-orifice yenkqubo iqhagamshelwe kwitheyibhile yoxinzelelo ihlolwe, uxinzelelo oluphantsi lunokufumaneka ngaphezulu kwexabiso eliqhelekileyo.
Ubushushu bokufunxa i-refrigerator refrigerator compressor bubushushu be-refrigerant kwi-inhalation valve. Ukuze kuqinisekiswe ukusebenza ngokukhuselekileyo kwe-compressor, kuthintelwe isiganeko se-liquid shock cylinder. Ubushushu bokufunxa kufuneka bube phezulu kancinci kunobushushu bokufuma, oko kuthetha ukuba i-refrigerant gas iba yi-superheated gas, enobushushu obuphezulu. Ngokubanzi, akukho subcooler ye-gas-liquid.
Kwinkqubo yeFreon efrijini, ubushushu begesi yokufunxa kufuneka bube yi-5℃iqondo lobushushu lobushushu liphezulu kunelokufuma, kwaye iqondo lobushushu begesi yokufunxa lifanelekile. Kwisixhobo sokufrijisa se-ammonia, iqondo lobushushu be-suction superheat ngokubanzi liyi-5~10℃, iqondo lokufunxa i-superheat likhulu kakhulu okanye lincinci kakhulu kufuneka liphetshwe, ukuba iqondo lobushushu obukhulu kakhulu, liya kwenza ukuba umthamo wefriji wehle, ubushushu bokukhupha umoya bunyuke, ukusetyenziswa kwamandla kunyuke, ukuba iqondo lobushushu obukhulu kakhulu lincinci kakhulu, kulula ukuvelisa isiganeko se-liquid strike cylinder.
