Cov Qauv thiab Hom Lub Tub Yees Evaporator

Lub tub yees evaporator yog dab tsi?

Lub tub yees evaporator yog lwm qhov tseem ceeb ntawm kev sib pauv cua sov ntawm lub tub yees txias system. Nws yog ib qho khoom siv uas tso tawm lub peev xwm txias hauv lub tub yees, thiab nws yog qhov tseem ceeb rau "sab nqus cua sov". Lub tub yees evaporators feem ntau yog ua los ntawm tooj liab thiab txhuas, thiab muaj phaj raj hom (aluminium) thiab hlau raj hom (platinum-nickel steel alloy). Cia txias sai sai.

Kev ua haujlwm thiab cov qauv ntawm lub tub yees evaporator

Lub tub yees system ntawm lub tub yees yog tsim los ntawm compressor, evaporator, lub txias txias, thiab lub raj capillary. Nyob rau hauv lub tub yees system, qhov loj thiab kev faib tawm ntawm cov evaporator ncaj qha cuam tshuam rau lub peev xwm txias thiab txias ceev ntawm lub tub yees system. Tam sim no, lub freezer compartment ntawm lub tub yees saum toj no feem ntau yog tub yees los ntawm ntau lub tshav kub pauv txheej evaporator. Lub tub rau khoom ntawm lub freezer compartment yog nyob nruab nrab ntawm cov khaubncaws sab nraud povtseg ntawm lub tshav kub exchanger txheej ntawm lub evaporator. Cov qauv ntawm cov evaporator yog muab faib ua steel hlau coils. Muaj ob lub qauv ntawm cov raj hom thiab txhuas phaj coil hom.

Qhov twgtub yees evaporator yog qhov zoo?

Muaj tsib hom evaporators feem ntau siv nyob rau hauv lub tub yees: finned coil hom, txhuas phaj cua tshuab, steel hlau kauj hom, thiab ib leeg-ridge finned raj hom.

1. Finned coil evaporator

Lub finned coil evaporator yog intercooled evaporator. Nws tsuas yog tsim rau cov tub yees tsis ncaj. Lub raj txhuas los yog tooj liab raj nrog txoj kab uas hla ntawm 8-12 hli feem ntau yog siv los ua cov tubular, thiab cov ntawv txhuas (los yog cov ntawv tooj liab) nrog lub thickness ntawm 0.15-3nun yog siv los ua cov fins, thiab qhov deb ntawm cov fins. yog 8-12mm. Cov tubular ib feem ntawm cov cuab yeej siv tsuas yog siv rau kev ncig ntawm cov tub yees, thiab qhov fin yog siv los nqus cov cua sov ntawm lub tub yees thiab lub tub yees. Finned coil evaporators feem ntau raug xaiv vim lawv qhov kub hloov pauv coefficient, me me hneev taw, ruaj khov, kev ntseeg tau, thiab lub neej ntev.

2. Aluminium phaj tshuab tshuab evaporator

Nws siv cov ntawv luam tawm ntawm ob daim ntawv txhuas, thiab tom qab calendering, qhov tsis tau luam tawm yog kub nias ua ke, thiab tom qab ntawd tshuab mus rau hauv txoj kev xyoob los ntawm kev kub siab. Cov evaporator no yog siv nyob rau hauv lub tub yees chambers ntawm flash-txiav ib lub qhov rooj tub yees, ob lub qhov rooj tub yees, thiab me me-loj ob-qhov rooj tub yees, thiab yog ntsia rau sab sauv ntawm lub rear phab ntsa ntawm lub tub yees nyob rau hauv daim ntawv ntawm ib tug evaporator. vaj huam sib luag.

3. Tube-phaj evaporator

Nws yog khoov lub raj tooj liab lossis txhuas raj (feem ntau 8 hli hauv txoj kab uas hla) rau hauv ib qho duab, thiab daim ntawv cog lus (lossis braze) nws nrog cov phaj txhuas sib xyaw. Ntawm lawv, lub raj tooj liab yog siv rau kev ncig ntawm lub tub yees; aluminium phaj yog siv los ua kom qhov chaw conduction. Hom evaporator no feem ntau yog siv los ua lub freezer evaporator thiab cua txias ncaj qha ntawm lub tub yees txias-freezer.
