Txoj cai ntawm lub tsheb cua txias evaporator
Ua ntej, hom evaporator
Evaporation yog txheej txheem lub cev uas cov kua hloov mus rau hauv cov pa. Lub tsheb cua txias evaporator muaj nyob rau hauv HVAC chav tsev thiab txhawb cov vaporization ntawm cov kua refrigerant los ntawm lub tshuab blower.
(1) Cov qauv tseem ceeb ntawm cov evaporator: tubular hom, tubular hom, cascading hom, parallel flow
(2) Cov yam ntxwv ntawm ntau hom evaporator
Lub vane evaporator yog tsim los ntawm txhuas lossis tooj liab puag ncig lub raj npog nrog txhuas fins. Aluminium fins yog nyob rau hauv kev sib cuag nrog lub round raj los ntawm raj expanding txheej txheem
Hom tubular vane evaporator no muaj cov qauv yooj yim thiab kev ua haujlwm yooj yim, tab sis qhov kev hloov hluav taws xob hloov hluav taws xob tsis zoo. Vim qhov yooj yim ntawm kev tsim khoom, tus nqi qis, yog li tus nqi qis, cov qauv qub tseem siv tau.
Hom evaporator no yog welded los ntawm ntxeem tau lub raj thiab serpentine txias aluminium strip. Cov txheej txheem yog qhov nyuaj dua li ntawm hom tubular. Ob chav sided composite aluminium thiab porous ca tube cov ntaub ntawv yuav tsum tau.
Qhov kom zoo dua yog tias cov cua sov hloov pauv tau zoo dua qub, tab sis qhov tsis zoo yog qhov tuab yog qhov loj thiab muaj pes tsawg leeg ntawm cov qhov hauv qhov loj, uas yog ib qho yooj yim uas yuav ua rau qhov tsis sib xws ntawm cov tub yees nyob rau hauv lub qhov thiab qhov nce ntawm irreversible poob. .
Cascade evaporator yog cov qauv siv dav tshaj plaws tam sim no. Nws yog tsim los ntawm ob daim hlau txhuas uas tau ntxuav rau hauv cov duab nyuaj thiab welded ua ke los tsim cov tub yees channel. Nyob nruab nrab ntawm txhua ob txoj kev sib xyaw ua ke muaj wavy fins rau cua sov dissipation.
Cov txiaj ntsig zoo yog qhov ua haujlwm siab hloov hluav taws xob, cov qauv compact, tab sis kev ua haujlwm nyuaj tshaj plaws, nqaim channel, yooj yim los thaiv.
Parallel flow evaporator yog ib hom evaporator feem ntau siv tam sim no. Nws yog tsim los ntawm lub hauv paus ntawm lub raj thiab siv evaporator qauv. Nws yog ib qho compact heat exchanger muaj li ntawm ob kab ntxeem tau lub raj ca thiab louver fin.
Qhov zoo yog cov kub hloov pauv coefficient (piv nrog cov tubular kub exchanger muaj peev xwm nce los ntawm ntau tshaj 30%), lub teeb yuag, compact qauv, tsawg dua refrigerant them nqi, thiab lwm yam. Qhov tsis txaus yog tias cov roj-kua ob-theem refrigerant ntawm txhua ca lub raj yog qhov nyuaj kom ua tiav kev faib tawm tsis sib xws, uas cuam tshuam rau kev hloov pauv cua sov thiab qhov kub ntawm qhov chaw faib khoom.
