Umahluko kubushushu bokupholisa kwiifriji ezincinci zorhwebo ubonakala njengongafikeleliyo kumgangatho. Umthengi ufuna ubushushu obuyi-2 ~ 8℃, kodwa ubushushu bokwenyani buyi-13 ~ 16℃. Isisombululo esiqhelekileyo kukucela umenzi ukuba atshintshe ukupholisa komoya ukusuka kumbhobho womoya omnye ukuya kumbhobho womoya ombini, kodwa umenzi akanazo iimeko ezinjalo. Olunye ukhetho kukutshintsha i-compressor ngeyombane onamandla aphezulu, eya kunyusa ixabiso, kwaye umthengi usenokungakwazi ukuyihlawula. Phantsi kwemiqathango emibini yemida yobuchwephesha kunye nokuqonda iindleko, kuyimfuneko ukuqala ngokusebenzisa amandla okusebenza kwezixhobo ezikhoyo kunye nokwenza ngcono ukusebenza ukuze ufumane isisombululo esinokuhlangabezana neemfuno zokupholisa kwaye sihambelane nohlahlo-lwabiwo mali.
1.Ukuphucula ukuphambuka kwendlela yokuhambisa umoya
Uyilo lwe-air duct enye lunendlela enye, nto leyo ebangela ukuba kubekho i-gradient yobushushu ecacileyo ngaphakathi kwikhabhinethi. Ukuba akukho mava kuyilo lwe-air duct ezimbini, isiphumo esifanayo sinokufezekiswa ngokulungiswa okungekho kwisakhiwo. Ngokukodwa, okokuqala, yongeza icandelo lokuphambuka elinokususwa ngaphakathi kwe-air duct ngaphandle kokutshintsha isakhiwo se-air duct yokuqala.
Okwesibini, faka i-splitter enomfanekiso ka-Y kwindawo yokukhupha umoya ye-evaporator ukuze yahlule ukuhamba komoya omnye ibe yimijelo emibini ephezulu nesezantsi: enye igcina indlela yokuqala ngqo kumaleko ophakathi, kwaye enye ikhokelwa kwindawo ephezulu nge-30° ejonge kwi-deflector. I-engile yefoloko ye-splitter ivavanyiwe nge-fluid dynamics simulation ukuqinisekisa ukuba umlinganiselo wokuhamba kwemijelo yomoya emibini yi-6:4, engagcini nje ngokuqinisekisa amandla okupholisa kwindawo engundoqo yomaleko ophakathi kodwa ikwazalisa indawo engaboniyo enobushushu obuphezulu obuyi-5cm phezulu. Kwangaxeshanye, faka ipleyiti yokubonakalisa efana ne-arc ezantsi kwekhabhinethi. Usebenzisa iimpawu zokutshona komoya obandayo, umoya obandayo oqokelelene ngokwemvelo ezantsi ubonakaliswa kwiikona eziphezulu ukuze wenze ukujikeleza kwesibini.
Okokugqibela, faka i-splitter, uvavanye isiphumo, kwaye ujonge ukuba amaqondo obushushu afikelela kwi-2 ~ 8℃. Ukuba oku kunokwenzeka, kuya kuba sisisombululo esifanelekileyo ngexabiso eliphantsi kakhulu.
2. Ukutshintshwa kwefriji
Ukuba ubushushu abuhli, phinda ufake i-refrigerant (ugcine imodeli yokuqala ingatshintshanga) ukuze wehlise ubushushu bokufuma ukuya kwi -8℃. Olu hlengahlengiso lonyusa umahluko wobushushu phakathi kwe-evaporator nomoya okwikhabhinethi nge-3℃, nto leyo ephucula ukusebenza kakuhle kotshintshiselwano lobushushu nge-22%. Buyisela ityhubhu ye-capillary ehambelanayo (yonyusa ububanzi bangaphakathi ukusuka kwi-0.6mm ukuya kwi-0.7mm) ukuqinisekisa ukuba ukuhamba kwe-refrigerant kuyahambelana nobushushu obutsha bokufuma kwaye uphephe umngcipheko wehammer yolwelo lwe-compressor.
Kufuneka kuqatshelwe ukuba ukulungiswa kobushushu kufuneka kudityaniswe nokulungiswa ngokuchanekileyo kwengqiqo yolawulo lobushushu. Tshintsha i-thermostat yomatshini yokuqala ngemodyuli yolawulo lobushushu ye-elektroniki kwaye usete indlela yokuqalisa kabini: xa ubushushu obuphakathi kwikhabhinethi budlula i-8℃, i-compressor inyanzelekile ukuba iqalise; oku akuqinisekisi nje kuphela isiphumo sokupholisa kodwa kukwagcina ukusebenza kakuhle kokupholisa kwimeko efanelekileyo.
3.Ukunciphisa ukuphazamiseka komthombo wobushushu bangaphandle
Ubushushu obugqithisileyo kwikhabhinethi budla ngokuba ngumphumo wokungalingani phakathi komthwalo wendalo kunye namandla okupholisa. Xa amandla okupholisa engenakonyuswa, ukunciphisa umthwalo wendalo wezixhobo kunokunciphisa ngokungangqalanga umsantsa phakathi kobushushu bokwenyani kunye nexabiso ekujoliswe kulo. Kwindawo entsonkothileyo yeendawo zorhwebo, uhlengahlengiso kunye notshintsho kufuneka lwenziwe ukusuka kumacala amathathu.
Okokuqala kukuqinisa i-insulation yobushushu bekhabhinethi. Faka iphaneli ye-vacuum insulation enobukhulu obuyi-2mm (iphaneli ye-VIP) kwicala langaphakathi lomnyango wekhabhinethi. Ukuqhuba kwayo ubushushu yi-1/5 kuphela ye-polyurethane yendabuko, kunciphisa ukulahleka kobushushu bomzimba womnyango ngama-40%. Kwangaxeshanye, ncamathisela i-cotton ye-insulation ehlanganisiweyo ye-aluminium foil (ubude obuyi-5mm) ngasemva nasemacaleni ekhabhinethi, ugxile ekugubungeleni iindawo apho i-condenser idibana khona nehlabathi langaphandle ukunciphisa impembelelo yobushushu obuphezulu kwinkqubo yefriji. Okwesibini, ukuze kudityaniswe ubushushu bendalo, faka i-sensor yobushushu ngaphakathi kweemitha ezi-2 ujikeleze ifriji. Xa ubushushu be-ambient budlula ama-28℃, vula ngokuzenzekelayo isixhobo sokukhupha umoya oshushu kwindawo ekufutshane ukuze sijike umoya oshushu uye kwiindawo ezikude nefriji ukuze kuthintelwe ukwenza i-envelope yobushushu.
4. Ukuphucula isicwangciso sokusebenza: ukuziqhelanisa ngokuguquguqukayo neemeko zokusetyenziswa
Ngokuseka icebo lokusebenza elihambelana neemeko zokusetyenziswa, uzinzo lokupholisa lunokuphuculwa ngaphandle kokunyusa iindleko zehardware. Misela imida yolawulo lobushushu ngamaxesha ahlukeneyo: gcina umda ophezulu wobushushu obujoliswe kubo kwi-8℃ ngexesha leeyure zomsebenzi (8:00-22:00), kwaye wehlise uye kwi-5℃ ngexesha leeyure ezingezizo ezeshishini (22:00-8:00). Sebenzisa ubushushu obuphantsi obujikeleze imozulu ebusuku ukuze upholise ikhabhinethi kwangaphambili ukuze ugcine umthamo obandayo kwishishini losuku olulandelayo. Kwangaxeshanye, lungisa umahluko wobushushu bokuvala ngokwexesha lokujika kokutya: setha umahluko wobushushu bokuvala kwi-2℃ (ukuvala kwi-8℃, qala kwi-10℃) ngamaxesha okuzaliswa kokutya rhoqo (njengencochoyi yasemini) ukunciphisa inani lokuqalisa nokuma kwecompressor; setha umahluko wobushushu kwi-4℃ ngexesha lokujika kancinci ukunciphisa ukusetyenziswa kwamandla.
5. Uthetha-thethana ngokutshintsha icompressor
Ukuba unobangela wengxaki kukuba amandla e-compressor mancinci kakhulu ukuba angafikelela kwi-2 ~ 8℃, kuyimfuneko ukuthetha nomthengi ukuze kutshintshwe i-compressor, kwaye injongo ephambili kukusombulula ingxaki yomahluko wobushushu.
Ukusombulula ingxaki yokwahluka kobushushu bokupholisa kwiifriji ezincinci zorhwebo, eyona nto iphambili kukufumanisa izizathu ezithile, nokuba ngamandla amancinci ecompressor okanye isiphene kuyilo lwemibhobho yomoya, kunye nokufumana isisombululo esifanelekileyo. Oku kukwasixelela ukubaluleka kovavanyo lobushushu.
