Uyazi na indlela yokunyibilikisa ezi gumbi zibandayo – i-Defrost Heating Tube?

A. Isishwankathelo

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. 

B. Injongo yokunyibilikisa iqhwa

1, ukuphucula ukusebenza kakuhle kwenkqubo yokukhenkcisa;

2. Qinisekisa umgangatho weemveliso ezikhenkcezisiweyo kwindawo yokugcina impahla;

3, wonge amandla;

4, yandisa ubomi benkonzo yenkqubo yokugcina ebandayo.

C. iindlela zokunyibilikisa iqhwa

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 kwimibhobho yokugcina ebandayo emikhulu, ephakathi nencinci:

I-condensate yegesi eshushu enobushushu obuphezulu ingena ngqo kwi-evaporator ngaphandle kokuthintela, kwaye ubushushu be-evaporator buyanyuka, nto leyo ebangela ukuba umaleko weqhwa kunye ne-cold discharge joint zinyibilike okanye zisuswe. Ukunyibilikisa igesi eshushu kungabizi kwaye kuthembekile, kulula ukugcinwa nokulawulwa, kwaye ubunzima bayo botyalo-mali kunye nokwakha abubukhulu.

2, nyibilikisa umkhenkce wesitshizi samanzi

Isetyenziswa kakhulu ekunyibilikiseni i-chiller enkulu nephakathi:

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% ukuya kwi-8% ye-brine exineneyo, ukuthintela ukwakheka kweqhwa.

3, ukunyibilikisa umbane

Umbhobho wobushushu wombane usetyenziswa kakhulu kwiifriji eziphakathi nezincinci:

Intambo yokufudumeza yombane isetyenziselwa kakhulu ukunyibilikisa ityhubhu yomgca we-aluminiyam kwindawo yokugcina ebandayo ephakathi nencinci, elula kwaye kulula ukuyisebenzisa kwi-chiller; Nangona kunjalo, kwimeko yokugcina ebandayo yetyhubhu ye-aluminiyam, ubunzima bokwakha bokufakelwa kwephini ye-aluminiyam yocingo lokufudumeza yombane abuncinci, kwaye izinga lokusilela liphezulu kwixesha elizayo, ukugcinwa nokulawulwa kunzima, uqoqosho luphantsi, kwaye ukhuseleko luphantsi.

4, ukunyibilikisa okwenziweyo ngoomatshini

Isicelo sokunyibilikisa umbhobho omncinci wokugcina ubushushu:

Ukunyibilikisa umbhobho ogcina izinto ezibandayo ngesandla kubiza kakhulu, indlela yokuqala yokunyibilikisa. Ukugcinwa okukhulu kwento ebandayo kunye nokunyibilikisa okwenziweyo akwenzeki, ukusebenza kwentloko kunzima, ukusetyenziswa ngokomzimba kukhawuleza kakhulu, ixesha lokugcina kwindawo yokugcina impahla lide kakhulu kwaye liyingozi empilweni, ukunyibilikisa akukho lula ukucokisa, kunokubangela ukuguquguquka kwe-evaporator, kwaye kunokwaphula i-evaporator ekhokelela kwiingozi zokuvuza.

D. Ukukhetha indlela yokunyibilikisa inkqubo ye-fluorine

Ngokwee-evaporator ezahlukeneyo zendawo yokugcina ebandayo, khetha indlela efanelekileyo yokunyibilikisa. Inani elincinci leendawo zokugcina ezibandayo ezincinci zisebenzisa ucango oluvaliweyo ukuze zinyibilikise ngokwendalo zisebenzisa ubushushu bomoya. Ezinye ii-chillers zelayibrari ezinobushushu obuphezulu zikhetha ukumisa ifriji, zivule ifeni ye-chiller ngokwahlukeneyo, zisebenzise ifeni ukuhambisa umoya ukuze unyibilikise, kwaye azivumeli umbhobho wobushushu wombane ukufezekisa injongo yokonga amandla.

1, indlela yokunyibilikisa iqhwa ye-cooler:

(1) Kukho iityhubhu zombane ezinyibilikisa iqhwa kwaye ukunyibilikisa amanzi kunokukhethwa, iindawo ezinamanzi alula zinokukhetha i-chiller yokunyibilikisa amanzi, iindawo zokunqongophala kwamanzi zikhetha i-chiller yokunyibilikisa iqhwa yombane.

(2) ukunyibilikisa ityhubhu yombane kusetyenziswa kakhulu ekunyibilikiseni i-air cooler encinci; I-frost chiller ekhupha amanzi idla ngokwenziwa kwinkqubo enkulu yokupholisa umoya kunye neyokukhenkceza.

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-fluoride eshushu ngombane.

Ixesha lokunyibilikisa iqhwa kwindawo yokugcina ebandayo

Ngoku uninzi lokunyibilikisa iqhwa kwindawo yokugcina izinto ezibandayo kulawulwa ngokwe-probe yobushushu bokunyibilikisa okanye ixesha lokunyibilikisa. Ubuninzi bokunyibilikisa, ixesha, kunye nobushushu bokumisa ukunyibilikisa kufuneka kulungiswe ngokwenani kunye nomgangatho weempahla ezipakishiweyo.

Ekupheleni kwexesha lokunyibilikisa, uze emva koko uye kwixesha lokuthontsiza, ifeni iyaqala. Lumka ungalibekeli ixesha lokunyibilikisa ixesha elide kakhulu kwaye uzame ukufikelela ekunyibilikiseni okufanelekileyo. (Umjikelo wokunyibilikisa ngokubanzi usekelwe kwixesha lombane okanye ixesha lokuqalisa kwecompressor.)

F. Uhlalutyo lwezizathu zeqhwa eligqithisileyo

Zininzi izizathu ezichaphazela ukwakheka kweqabaka, ezinje: ulwakhiwo lwe-evaporator, imeko-bume yomoya (ubushushu, ukufuma) kunye nesantya sokuhamba komoya. Iziphumo ekwakhekeni kweqabaka kunye nokusebenza komoya opholileyo zezi zilandelayo:

1, umahluko wobushushu phakathi komoya wokungena kunye nefeni yokugcina ebandayo;

2, ukufuma komoya ophefumliweyo;

3, isithuba phakathi kwamaphiko;

4, izinga lokuhamba komoya ongenayo.

Xa ubushushu bokugcina bungaphezulu kwe-8℃, inkqubo eqhelekileyo yokugcina ebandayo phantse ayiqandi; Xa ubushushu obuphakathi buyi-5℃ ~ 3℃ kwaye umswakama womoya mkhulu, kulula ukuyiqandisa; Xa ubushushu obuphakathi buphantsi, isantya sokwakheka kweqabaka siyancipha kuba umswakama emoyeni uyancipha.
