Ngenxa yeqabaka elikumphezulu we-evaporator kwindawo yokugcina ebandayo, ithintela ukuhanjiswa kunye nokusasazwa kwamandla okubanda e-evaporator yefriji (umbhobho), kwaye ekugqibeleni ichaphazela isiphumo sefriji. Xa ubukhulu bomaleko weqabaka (umkhenkce) kumphezulu we-evaporator bufikelela kwinqanaba elithile, ukusebenza kakuhle kwefriji kwehla ukuya ngaphantsi kwama-30%, okubangela inkcitho enkulu yamandla ombane kunye nokunciphisa ubomi benkonzo yenkqubo yefriji. Ke ngoko, kuyimfuneko ukwenza umsebenzi wokunyibilikisa iqhwa kwindawo yokugcina ebandayo kumjikelo ofanelekileyo.
Injongo yokunyibilikisa
1, ukuphucula ukusebenza kakuhle kwenkqubo yokukhenkcisa;
2. Qinisekisa umgangatho weemveliso ezikhenkcezisiweyo kwindawo yokugcina impahla
3, wonge amandla;
4, yandisa ubomi benkonzo yenkqubo yokugcina ebandayo.
Indlela yokunyibilikisa
Iindlela zokunyibilikisa i-frost yokugcina izinto ezibandayo: ukunyibilikisa igesi eshushu (ukunyibilikisa i-fluorine eshushu, ukunyibilikisa i-ammonia eshushu), ukunyibilikisa amanzi, ukunyibilikisa umbane, ukunyibilikisa ngoomatshini (okwenziwayo), njl.
1, igesi eshushu iyanyibilikisa
Ifanelekile kumbhobho omkhulu, ophakathi nomncinci wokugcina ubushushu obandayo onyibilikisa ngqo i-condensate yegesi eshushu enobushushu obuphezulu iye kwi-evaporator ngaphandle kokuyeka ukuhamba, ubushushu be-evaporator buyanyuka, kwaye umaleko weqhwa kunye nejoyinti yokukhupha ebandayo ziyanyibilika okanye emva koko ziqhekeke. Ukunyibilikisa igesi eshushu kungabizi kwaye kuthembekile, kulula ukugcinwa kunye nolawulo, kwaye ubunzima bayo botyalo-mali kunye nokwakha abubukhulu. Nangona kunjalo, kukwakho neenkqubo ezininzi zokunyibilikisa igesi eshushu, indlela eqhelekileyo kukuthumela igesi enoxinzelelo oluphezulu kunye nobushushu obuphezulu ekhutshwe kwi-compressor iye kwi-evaporator ukuze ikhuphe ubushushu kunye nokunyibilikisa, ukuze ulwelo oluxineneyo lungene kwenye i-evaporator ukuze ifunxe ubushushu kwaye iphele kwigesi enobushushu obuphantsi kunye noxinzelelo oluphantsi, ize ibuyele kwi-port ye-compressor suction ukuze igqibezele umjikelo.
2, nyibilikisa umkhenkce wesitshizi samanzi
Isetyenziswa kakhulu ekunyibilikiseni iifriji ezinkulu neziphakathi
Qho xa utshiza i-evaporator ngamanzi obushushu begumbi rhoqo ukuze unyibilikise umaleko weqhwa. Nangona isiphumo sokunyibilikisa silungile kakhulu, sifanelekile ngakumbi kwii-air coolers, kwaye kunzima ukuyisebenzisa kwiikhoyili zokufuma. Kunokwenzeka nokutshiza i-evaporator ngesisombululo esinobushushu obuphezulu bokuqanda, njenge-5%-8% ye-brine exineneyo, ukuthintela ukwakheka kweqhwa.
3. Ukunyibilikisa ubushushu ngombane
Ukunyibilikisa umbhobho wobushushu wombane kusetyenziswa kakhulu kwi-air cooler ephakathi nencinci; Ukunyibilikisa intambo yokufudumeza yombane kusetyenziswa kakhulu kwiityhubhu ze-aluminiyam zokugcina izinto ezibandayo eziphakathi nezincinci.
Ukunyibilikisa ubushushu ngombane, kwi-chiller kulula kwaye kulula ukuyisebenzisa; Nangona kunjalo, kwimeko yokugcina ebandayo yetyhubhu ye-aluminium, ubunzima bokwakha bokufakelwa kwe-aluminium fin yocingo lokufudumeza ngombane abuncinci, kwaye izinga lokusilela liphezulu kwixesha elizayo, ukugcinwa nokulawulwa kunzima, uqoqosho alulunganga, kwaye ukhuseleko luphantsi.
4, ukunyibilikisa okwenziweyo ngoomatshini
Ukunyibilikisa umbhobho omncinci wokugcina ubushushu kwipayipi yokugcina ubushushu ngesandla kubiza kakhulu, yeyona ndlela yokuqala yokunyibilikisa. Ukugcinwa okukhulu kobushushu obunobushushu bokwenziwa akunamsebenzi, ukusebenza kwentloko phezulu kunzima, ukusetyenziswa ngokomzimba kukhawuleza kakhulu, ixesha lokugcina kwindawo yokugcina impahla lide kakhulu kuyingozi empilweni, ukunyibilikisa akukho lula ukukugqiba, kunokubangela ukuguquguquka kwe-evaporator, kwaye kunokuphula i-evaporator kwaye kukhokelele kwiingozi zokuvuza kwefriji.
Ukukhetha imo (inkqubo yeFluorine)
Ngokwee-evaporator ezahlukeneyo zendawo yokugcina ebandayo, kukhethwa indlela yokunyibilikisa efanelekileyo, kwaye ukusetyenziswa kwamandla, ukusetyenziswa kwe-safety factor, ubunzima bokufakelwa kunye nokusebenza kuhlolwa ngakumbi.
1, indlela yokunyibilikisa ifeni ebandayo
Kukho iityhubhu zombane ezinyibilikisa iqhwa kwaye ukunyibilikisa amanzi kunokukhetha. Iindawo ezisebenzisa amanzi ngokulula zinokukhetha i-frost chiller ehluza amanzi, kwaye iindawo ezinqongopheleyo amanzi zikhetha i-electric heat pipe frost chiller. I-frost chiller ehluza amanzi idla ngokwenziwa kwinkqubo enkulu yokupholisa umoya kunye nefriji.
2. Indlela yokunyibilikisa umqolo wentsimbi
Kukho iindlela zokunyibilikisa i-fluorine eshushu kunye neendlela zokunyibilikisa i-frost ezenziweyo.
3. Indlela yokunyibilikisa i-aluminium tube
Kukho iindlela zokunyibilikisa i-fluoride eshushu kunye neendlela zokunyibilikisa i-thermal thermal. Ngokusetyenziswa kakhulu kwe-aluminium tube evaporator, ukunyibilikisa i-aluminium tube kuye kwanikwa ingqalelo ngakumbi ngabasebenzisi. Ngenxa yezizathu zezinto eziphathekayo, i-aluminium tube ayifanelekanga ukusetyenziswa kwe-mechanical defrosting elula nerhabaxa efana nentsimbi, ngoko ke indlela yokunyibilikisa i-aluminium tube kufuneka ikhethe indlela yokunyibilikisa i-electric wire kunye ne-hot fluorine defrosting, idibene nokusetyenziswa kwamandla, umlinganiselo wokusebenza kakuhle kwamandla kunye nokhuseleko kunye nezinye izinto, ukunyibilikisa i-aluminium tube kufanelekile ngakumbi ukukhetha indlela yokunyibilikisa i-fluorine eshushu.
Ukusetyenziswa kokunyibilikisa i-fluoride eshushu
Izixhobo zokuguqula indlela yokuhamba kwe-freon eziphuhliswe ngokomgaqo wokunyibilikisa igesi eshushu, okanye inkqubo yokuguqula eyenziwe ziivalvu ezininzi ze-electromagnetic (iivalvu zesandla) ezidityanisiweyo, oko kukuthi, isikhululo sokulawula i-refrigerant, sinokwenza ukusetyenziswa kokunyibilikisa i-fluorine eshushu kwindawo yokugcina ebandayo.
1, isikhululo sokulungisa ngesandla
Isetyenziswa kakhulu kwiinkqubo ezinkulu zokukhenkcisa ezifana noqhagamshelo oluhambelanayo.
2, izixhobo zokuguqula i-fluorine eshushu
Isetyenziswa kakhulu kwinkqubo yokukhenkcisa enye encinci nephakathi. Ezifana: isixhobo esinye esibalulekileyo sokuguqula i-fluorine eshushu.
Ukucofa kanye i-fluorine eshushu enyibilikisa iqhwa
Ifanelekile kwinkqubo yokujikeleza ezimeleyo yecompressor enye (ayifanelekanga ukufakwa koqhagamshelo lweeyunithi ezilinganayo, ezinamanqanaba amaninzi kunye nezigqithanayo). Isetyenziswa ekunyibilikiseni imibhobho yokugcina izinto ezibandayo encinci nephakathi kunye nokunyibilikisa umkhenkce kushishino.
ukungaqhelekanga
1, ulawulo lwesandla, ukuguqulwa kokucofa kube kanye.
2, ukufudumeza ngaphakathi, umaleko weqabaka kunye nodonga lombhobho zinokunyibilika kwaye ziwe, umlinganiselo wokusetyenziswa kakuhle kwamandla yi-1:2.5.
3, xa inyibilikiswa kakuhle, ngaphezulu kwe-80% yomaleko weqabaka yithontsi eliqinileyo.
4, ngokwendlela umzobo ofakwe ngqo kwiyunithi yokufunxa, awudingi ezinye izixhobo ezikhethekileyo.
5, ngokweeyantlukwano zokwenyani kubushushu obungqongileyo, ngokubanzi kuthatha imizuzu engama-30 ukuya kwe-150.
