I-evaporator yenkqubo yokugcina ebandayo kufuneka inikele ingqalelo ekugcinweni. Ukuba i-evaporator frosting iya kuchaphazela ukusetyenziswa okuqhelekileyo kwendawo yokugcina ebandayo, indlela yokucima ngexesha? Ingcali yethu yokufakela ukugcinwa okubandayo kwiingcebiso zokupholisa ebusuku kufuneka ubeke ingqalelo kumanqaku e-evaporator frosting iya kukhokelela ekwandeni kokumelana ne-thermal, i-coefficient yokudlulisa ubushushu iyancipha. Kwi-chiller, indawo ye-cross-sectional of flow flow iyancitshiswa, ukuchasana kokuhamba kwanda, kwaye ukusetyenziswa kwamandla kwanda. Ngoko ke, kufuneka ihlanjululwe ngexesha.
Izicwangciso zangoku zokugcina ezibandayo zezi zilandelayo:
1. I-frosting Manual ilula kwaye ilula, kwaye inefuthe elincinci kwiqondo lokushisa lokugcina, kodwa ubuninzi bomsebenzi bukhulu, ukuchithwa akukona ngokucokisekileyo, kwaye kukho imida.
2. Amanzi ahlanjululwe, kwaye amanzi eqabaka atshizwe kumphezulu we-evaporator ngokusebenzisa isixhobo sokutshiza ukunyibilikisa i-double layer, kwaye ikhutshwe ngumbhobho wokuhambisa amanzi. Iskimu sinokusebenza okuphezulu, inkqubo yokusebenza elula kunye nokuguquguquka okuncinci kobushushu bokugcina. Ukusuka kwindawo yokujonga amandla, umthamo wokupholisa ngemitha yesikweri yendawo yokuphuphuma kwamanzi unokufikelela kwi-250-400kj. Ukugungxulwa kwamanzi kwenza kube lula ukugrumba ngaphakathi kwendawo yokugcina impahla, nto leyo ebangela ukuthontsiza kwamanzi kuphahla olubandayo, nto leyo enciphisa ubomi benkonzo.
3. Ukutshatyalaliswa komoya oshushu, usebenzisa ubushushu obukhutshwe ngumphunga ogqithisiweyo okhutshwe kwi-compressor ukuze unyibilike umaleko ophindwe kabini kumphezulu we-evaporator. Iimpawu zayo kukusebenziseka okuqinileyo kunye nengqiqo ekusebenziseni amandla. Kwinkqubo yefriji ye-ammonia, i-defrosting ingaphinda ikhuphe ioli kwi-evaporator, kodwa ixesha lokutshatyalaliswa lide, elinempembelelo ethile kwiqondo lokushisa lokugcina. Inkqubo yefriji inzima.
I-4, ukufudumeza kombane kunye nokutshitshiswa, usebenzisa into yokufudumeza ukufudumeza ukugcinwa okubandayo ukuze kuncitshiswe. Inkqubo ilula, kulula ukuyisebenzisa, kulula ukuzenzela, kodwa isebenzisa amandla amaninzi.
Xa isicwangciso sangempela sichongiwe, ngamanye amaxesha kusetyenziswa iskimu sokuqhaqha, kwaye ngamanye amaxesha amacebo ahlukeneyo adityaniswa. Njengombhobho weshelufu yokugcina ebandayo, udonga, umbhobho ogudileyo ongaphezulu, ungasebenzisa indibaniselwano eyenziweyo yendlela yegesi eshushu, ngokuqhelekileyo iqabaka ngesandla, i-defrost yomoya oshushu rhoqo, ukuqonda kakuhle iqabaka etshayela ngokwenziwa akukho lula ukususa iqabaka kunye nokukhupha ioli. kumbhobho . I-air blower igungxulwa ngamanzi kunye nomoya oshushu. Ukwenza iqabaka engakumbi, ukunyibilika rhoqo kunokwenziwa ngumoya oshushu odityaniswe nokuthotywa kwamanzi. Xa inkqubo yefriji yokugcina ebandayo isebenza, ubushushu bomphezulu we-evaporator buhlala bungaphantsi kwe-zero. Ngoko ke, i-evaporator ixhomekeke kwi-frosting, kwaye i-frost layer inokumelana ne-thermal enkulu, ngoko ke kufuneka unyango oluyimfuneko lwe-defrosting xa iqabaka inzima.
I-evaporator yogcino olubandayo lwahlulwe lube luhlobo lombhobho wodonga kunye nohlobo lwe-fin ngokwesakhiwo sayo, uhlobo lokufuduswa eludongeni lugqithiso lwendalo lokuhambisa ubushushu, uhlobo lwe-fin lunyanzeliswa ukuhanjiswa kobushushu, kunye nendlela yokuphelisa umbhobho. iqhele ukwenziwa ngesandla. I-Frost, i-fin type ene-cream yokufudumala yombane.
Ukunyibilikiswa kweqhwa ngesandla kuyingxaki ngakumbi. Kuyimfuneko ukunyibilika ngesandla, ukucoca iqabaka, kwaye uhambise imixholo yethala leencwadi. Ngokuqhelekileyo, umsebenzisi kufuneka aye kwi-defrosting ixesha elide okanye iinyanga ezimbalwa. Xa i-defrosting, i-frost layer sele inzima. Ukumelana ne-thermal yomaleko kwenze i-evaporator kude nokufikelela kwifriji. Ukutshatyalaliswa kokufudumeza kombane linyathelo elinye elingaphaya kokunciphisa i-manual defrosting, kodwa kukhawulelwe kwii-evaporators ezifakwe emanzini, i-evaporators eludongeni kunye ne-tube ayinakusetyenziswa.
Uhlobo lokufudumala kombane kufuneka lufakwe kwi-tube yokufudumala yombane kwi-evaporator yohlobo lwe-fin, kunye ne-tube yokufudumala yombane kufuneka ifakwe kwi-tray yokufumana amanzi. Ukuze ususe iqhwa ngokukhawuleza, amandla ombane wokufudumeza ityhubhu akakwazi ukukhethwa amancinci, ngokuqhelekileyo Kuya kuba ngama-kilowatts ambalwa. Indlela yokulawula ukusebenza kwetyhubhu yokufudumala yombane ithatha ngokubanzi ixesha lokulawula ukushisa. Xa ukufudumala, ityhubhu yokufudumeza yombane idlulisela ubushushu kwi-evaporator, kwaye inxalenye yeqabaka kwi-coil yokuphefumula kunye ne-fin iyanyibilika, kwaye inxalenye yeqabaka ayinyibiliki ngokupheleleyo i-tray yamanzi ewayo, kwaye iyafudumala kwaye inyibilike. ityhubhu yokufudumeza yombane kwitreyi yokufumana amanzi. Le yinkcitho yombane, kwaye umphumo wokupholisa ubi kakhulu. Ngenxa yokuba i-evaporator izele yiqabaka, i-coefficient yokutshintsha ubushushu iphantsi kakhulu.
Indlela engaqhelekanga yokugcina ebandayo yokuphelisa iqhwa
1. Ukutshatyalaliswa kwegesi eshushu yeenkqubo ezincinci, inkqubo kunye nendlela yokulawula ilula, isantya sokutshatyalaliswa ngokukhawuleza, iyunifomu kwaye ikhuselekile, kwaye uluhlu lwesicelo kufuneka lwandiswe ngakumbi.
2. I-pneumatic defrosting ifaneleke ngokukodwa kwiinkqubo zefriji ezifuna ukuchithwa rhoqo. Nangona kuyimfuneko ukongeza umthombo okhethekileyo womoya kunye nezixhobo zonyango lomoya, nje ukuba izinga lokusetyenziswa liphezulu, uqoqosho luya kuba luhle kakhulu.
3. I-ultrasonic defrosting yindlela ecacileyo yokunciphisa amandla okugcina amandla. Uyilo lweejeneretha ze-ultrasonic kufuneka lufundwe ngakumbi ukuze kuphuculwe ukucokiseka kokutshatyalaliswa kwezicelo zobunjineli.
I-4, i-refrigerant ye-liquid defrosting, inkqubo yokupholisa kunye nenkqubo yokuqhaqha ngexesha elifanayo, akukho kusetyenziswa kwamandla ongezelelweyo ngexesha lokuqhaqha, ukupholisa iqabaka kusetyenziselwa ifriji yolwelo phambi kwevalve yokwandisa i-supercooling, ukuphucula ukusebenza kakuhle kokupholisa ukuze ubushushu bethala leencwadi bugcinwe ngokusisiseko. Ubushushu befriji yolwelo bungaphakathi kwiqondo lokushisa eliqhelekileyo, kwaye ukunyuka kweqondo lokushisa kwe-evaporator ngexesha lokutshatyalaliswa kuncinci, okunempembelelo encinci ekudakaleni kokutshintshwa kobushushu be-evaporator. Ukungalungi kukuba ulawulo olunzima lwenkqubo lunzima.
Ngethuba lexesha lokuqhaqha, ngokuqhelekileyo kungakhathaliseki ukuba iqondo lokushisa. Ixesha lokuqhaqha liphelile, kwaye emva kwexesha lokuthontsiza, i-fan iqala kwakhona. Ixesha lakho lokunciphisa akufanele libekwe ixesha elide, kwaye ukhilimu wokufudumeza kombane akufanele udlule imizuzu engama-25. Zama ukufezekisa ukutshatyalaliswa okufanelekileyo. (Umjikelo wokuthomalalisa ngokuqhelekileyo usekwe kwixesha lothumelo lwamandla okanye ixesha lokuqalisa icompressor.) Olunye ulawulo lobushushu be-elektroniki lukwaxhasa ubushushu bokuphela kweqhwa. Iphelisa ukunyibilika kwiindlela ezimbini, i-1 lixesha kunye no-2 ngukwen. Oku kusebenzisa ngokubanzi i-2 probes yobushushu.
Ekusetyenzisweni kwansuku zonke kokugcinwa okubandayo, kuyimfuneko ukususa rhoqo iqhwa kwindawo yokugcina ebandayo. Iqhwa eligqithisileyo kwindawo yokugcina ebandayo ayihambisani nokusetyenziswa okuqhelekileyo kwendawo yokugcina ebandayo. Ephepheni, iinkcukacha zeqhwa kwindawo yokugcina ebandayo kufuneka zithathwe. Indlela yokuyisusa? Ziziphi iindlela zobugcisa eziqhelekileyo?
1. Khangela ifriji kwaye ukhangele ukuba kukho iqamza kwiglasi yokubona. Ukuba kukho i-bubble ebonisa ukungonelanga, yongeza ifriji ukusuka kumbhobho woxinzelelo oluphantsi.
