Ukugcinwa okubandayo yindawo yokugcina impahla esebenzisa izixhobo zokupholisa ukudala ukufuma okufanelekileyo kunye neemeko zokushisa eziphantsi. Ikwabizwa ngokuba yindawo yokugcina ebandayo. Yindawo apho iimveliso zicutshungulwa kwaye zigcinwe khona. Iyakwazi ukususa impembelelo yemozulu kwaye yandise ixesha lokugcinwa kweemveliso ezahlukeneyo ukulawula ukunikezelwa kweemarike.
Injongo yesistim yefriji yokugcina ebandayo:
Umgaqo osebenzayo wenkqubo yefriji Injongo yefriji kukusebenzisa iindlela ezithile zokudlulisa ubushushu bento yokugcina ebandayo edibeneyo kumanzi aphakathi ambient okanye umoya, ukuze ubushushu bento epholileyo buthotywe ngaphantsi kweqondo lokushisa kunye nokugcinwa ngexesha elithile. ubushushu.
Ukwakheka kwenkqubo yogcino lwefriji yogcino olubandayo:
Inkqubo yokucoca umphunga opheleleyo kufuneka ibandakanye inkqubo yokujikeleza kwefriji, i-lubricating oil circulation system, i-defrosting system, i-cooling circulation system kunye ne-refrigerant circulation system, njl.
Ngenxa yobunzima kunye nobuchwephesha benkqubo yefriji yokugcina ibanda, ezinye iimpazamo eziqhelekileyo ziya kwenzeka ngokuqinisekileyo ngexesha lokusebenza.
| Ukusilela kwenkqubo yokupholisa yokugcina ebandayo | Unobangela
|
| Ukuvuza kwefriji | Emva kokuvuza kwefriji kwisistim, amandla okupholisa ayanelanga, ukufunxa kunye nokukhupha uxinzelelo kuphantsi, kwaye isandi "sokuncwina" sisandi esikhulu kunesiqhelo sinokuvakala kwivalve yokwandisa. Akukho qabaka okanye iqabaka encinci edadayo kwi-evaporator. Ukuba umngxuma wevalve yokwandisa wandiswa, uxinzelelo lokufunxa alukatshintshi kakhulu. Emva kokuvalwa, uxinzelelo lwe-equilibrium kwinkqubo ngokubanzi luphantsi kunoxinzelelo lwe-saturation oluhambelana nobushushu obufanayo.

| Ukutshaja okugqithisileyo kwefriji emva kokugcinwa | Isixa sefriji esihlawuliswa kwisistim sefriji emva kokugcinwa kudlula umthamo wenkqubo, kwaye ifriji iya kuthatha umthamo othile we-condenser, ukunciphisa indawo yokutshatyalaliswa kobushushu, kunye nokunciphisa umphumo wokupholisa. Ukufunxa kunye noxinzelelo lokukhupha luphezulu jikelele kunexabiso loxinzelelo oluqhelekileyo, i-evaporator ayiqabanga ngokuqinileyo, kwaye ukupholisa kwindawo yokugcina impahla kuyacotha. |
| Kukho umoya kwisixokelelwano sefriji | Umoya okwinkqubo yefriji uya kunciphisa ukusebenza kakuhle kwefriji. Into ecacileyo kukuba i-suction and exhaust pressures iyanda (kodwa i-exhaust pressure ayidlulanga ixabiso elilinganisiweyo), kunye ne-compressor outlet kwi-condenser inlet Ukushisa kwandisa kakhulu. Ngenxa yobukho bomoya kwisistim, uxinzelelo lokukhupha kunye nokukhupha ukushisa kwanda. |
| Ukusebenza kwecompressor ephantsi | Ukusebenza okuphantsi kwe-compressor yefriji kubhekisela kwinto yokuba umthamo wangempela wokukhupha uyancipha kwaye umthamo wefriji uyancipha ngokufanelekileyo xa iimeko zokusebenza zihlala zingatshintshi. Le nto iyenzeka kakhulu kwiicompressors eziye zasetyenziswa ixesha elide. Ukugqoka kunye nokukrazula kwe-compressors kukhulu, ukucaciswa okuhambelanayo kwecandelo ngalinye kukhulu, kwaye ukusebenza kokutywinwa kwe-valve yomoya kuncitshisiwe, okubangelwa ukuhla komthamo wangempela wokukhupha. |
| Iqabaka kumphezulu we-evaporator ingqingqwa kakhulu | ukusetyenziswa kwexesha elide kwe-evaporator yokugcina ebandayo kufuneka ihlanjululwe rhoqo. Ukuba ayincitshiswanga, umaleko weqabaka kumbhobho womphunga uya kuqokelelana kwaye ujiye. Xa wonke umbhobho usongelwe kumaleko womkhenkce ocacileyo, Uya kuchaphazela ngokunzulu ukuhanjiswa kobushushu, kubangele ubushushu kwindawo yokugcina impahla ziwe ngaphantsi koluhlu olufunekayo. |
| Kukho i-oyile efrijiweyo kumbhobho we-evaporator | Ngexesha lomjikelo wefriji, enye ioli efrijini ihlala kumbhobho we-evaporator. Emva kwexesha elide lokusetyenziswa, ukuba kukho ioli eninzi eshiyekileyo kwi-evaporator, iya kuchaphazela kakhulu umphumo wayo wokudlulisa ubushushu. , isenzeko sokupholisa kakubi kwenzeka. |
| Inkqubo yefriji ayigudi | ngenxa yokucocwa kakubi kwenkqubo yefriji, emva kwexesha lokusetyenziswa, ukungcola ngokuthe ngcembe kuqokelelwa kwisihlunu, kwaye ezinye i-meshes zivaliwe, ezinciphisa ukuhamba kwefriji kwaye zichaphazela umphumo wokupholisa. Kwinkqubo, ivalve yokwandisa kunye nesihluzi kwizibuko lokufunxa lecompressor nazo zivaliwe kancinci. |
| Umngxuma wevalve yokwandisa umkhenkce kwaye uvalekile | amacandelo aphambili kwinkqubo yefriji ayimiswanga ngokufanelekileyo, ukucocwa kwenkqubo yonke akuphelelanga, kwaye umgangatho womswakama wefriji udlula umgangatho. |
| Ukuvaleka okumdaka kwisikrini sokucoca sevalve yokwandisa |
