Xaiv ib qho chaw tsim nyogdefrost rhaub cua sov rajrau cov khoom siv tub yees (tub yees, lub tub yees khov, chaw cia khoom txias, cov tshuab ua dej khov, thiab lwm yam) yog raws li 3 yam tseem ceeb: hom khoom siv / qhov chaw teeb tsa, qhov chaw teeb tsa tiag tiag, thiab qhov chaw ua haujlwm muab hluav taws xob. Kev xaiv yuav tsum ua raws li cov ntsiab cai ntawm kev sib phim qhov ntev ntawm kev teeb tsa, lub zog hloov kho tau, thiab lub zog hluav taws xob ua raws li - zam kev siv hluav taws xob tsawg (kev yaj tsis txaus) lossis cov lus qhia loj (lub zog pov tseg, kev puas tsuaj ntawm cov khoom siv).
Phau ntawv qhia no muab ib txoj kev xaiv ib kauj ruam zuj zus (haum rau cov khoom siv tub yees hauv tsev/kev lag luam/kev lag luam) thiab cov cai sib phim sai, uas tuaj yeem coj ncaj qha rau kev yuav khoom thiab hloov pauv.
Kauj Ruam 1: Paub meej tias qhov chaw siv lub hauv paus ntawm lub tshuab cua sov (Txiav txim siab qhov qauv duab)
Cov duab ntawm lublub tshuab cua sov defrostLub raj cua sov tau phim 100% rau qhov chaw teeb tsa ntawm cov khoom siv (cov kauj ruam xaiv yooj yim tshaj plaws). Cov chaw yaj dej khov sib txawv sib xws rau cov qauv ruaj khov, thiab kev xaiv cov duab tsis raug yuav ua rau tsis muaj peev xwm teeb tsa.
| Txoj Haujlwm Teeb tsa | Lub Tshuab Ua Kub Pom Zoo | Cov laj thawj xaiv tseem ceeb |
|---|---|---|
| Lub tub yees/lub tub yees khov (cheeb tsam yaj khov) | U-hom (mainstream) / M-hom (cov evaporators loj rau kev lag luam) | U-hom haum rau qhov sib nrug ntawm cov fin ntawm cov evaporators me me hauv tsev / lag luam; M-hom muaj thaj chaw cua sov loj dua rau cov evaporators loj finned |
| Lub lauj kaub dej/cov kav dej ntws (tiv thaiv kev khov/tiv thaiv kev txhaws) | Hom ncaj | Cov qauv linear yog yooj yim rau kev tso raws lub lauj kaub dej / yeeb nkab, qhov chaw me me nyob |
| Lub tshuab cua txias loj / lub tshuab cua txias rau kev lag luam | M-hom (finned xaiv tau) | Kev tsim finned ua rau thaj chaw cua sov dissipation nce ntxiv, ua tau raws li qhov xav tau defrosting loj ntawm cov khoom siv kev lag luam |

Txoj cai xaiv: lub raj cua sov txoj kab uas hla ≤ 80% ntawm qhov sib txawv (tsis txhob cuam tshuam lossis xoob qhov kev teeb tsa).
— Φ6.5mm: Qhov sib txawv tseg 6 ~ 10mm (tsev neeg ib lub / ob lub qhov rooj tub yees evaporators, cov kav dej me me)
— Φ8.0mm: Qhov sib txawv tseg 10 ~ 15mm (cov tub yees hauv tsev neeg, cov tub yees ncaj, cov txee tso saib me me)
— Φ10.7mm: Qhov sib txawv tseg ≥15mm (cov tub yees loj loj, cov khoom siv cia khoom txias, cov khoom siv lag luam)
2.2 Yuav ntsuas qhov ntev ntawm lub tshuab cua sov defrost li cas (tsis tas yuav muaj cov xov hlau txhuas/cov brackets)
— Hom Ncaj: Ntsuas qhov ntev ntawm txoj haujlwm yaj/tiv thaiv kev khov (piv txwv li, qhov ntev ntawm cov yeeb nkab ntws = qhov ntev ntawm cov yeeb nkab ncaj)
— Hom U: Ntsuas ob qhov tseem ceeb: qhov ntev ntawm ib sab caj npab (qhov ntev ntawm lub cua sov txuas rau lub evaporator fin) thiab qhov dav qhib hom U (sib phim qhov sib nrug sab laug-sab xis ntawm lub evaporator); qhov siab tag nrho yog txiav txim siab los ntawm qhov siab ntsug ntawm lub evaporator (qhov dav qhib feem ntau yog 80 ~ 150 hli rau cov khoom siv hauv tsev)
— Hom M: Ntsuas tag nrho qhov ncig ntawm lub evaporator loj; qhov ntev ntawm lub raj M-hom yog 90% ntawm qhov ncig ntawm lub evaporator (kom ntseeg tau tias tag nrho cov dej khov yaj)
— Cov raj xa dej tshwj xeeb: Kos cov duab qhia txog kev teeb tsa tiag tiag ntawm cov khoom siv, thiab cov chaw tsim khoom kho qhov ntev raws li cov duab qhia.
Cov Lus Cim Tseem Ceeb
Txhua qhov ntev yog hais txog qhov ua kom sov tau zoo ntawm lub cev raj - tsis suav nrog cov xov hlau txhuas, cov ntsia hlau kho, thiab cov qhov kawg kaw (cov chaw tsim khoom yuav ntxiv cov khoom no los ntawm lub neej ntawd, tsis tas yuav ntsuas ntxiv).
Kauj Ruam 3: Sib phim qhov Rated Voltage & Xam lub zog xav tau (Tiv thaiv kev pov tseg zog / kev yaj dej khov tsis ua haujlwm)
Qhov hluav taws xob yuav tsum sib xws 100% nrog rau lub zog ua haujlwm ntawm cov khoom siv; lub zog raug suav raws li thaj chaw yaj, qhov kub thiab txias, thiab qhov ntim ntawm cov khoom siv - lub hauv paus kom ntseeg tau tias yaj tau zoo yam tsis muaj kev kub dhau hauv zos.
3.1 Kev xaiv hluav taws xob (ib qho ntawm cov cim qhia nyuaj, tsis pub muaj qhov tsis sib xws)
| Cov Khoom Siv Ua Haujlwm Fais Fab | Lub Hwj Chim Hluav Taws Xob Pom Zoo | Hom Khoom Siv Tau |
