Yuav ua li cas koj txiav txim siab evaporation thiab condensation kub?

1. Condensation kub:

Lub condensation kub ntawm lub tub yees system yog hais txog qhov kub thiab txias thaum lub refrigerant condenses nyob rau hauv lub condenser, thiab cov refrigerant vapor siab yog lub condensation siab.Rau cov dej-txias condenser, qhov condensing kub yog feem ntau 3-5 ℃ siab tshaj qhov txias dej kub.

Condensation kub yog ib qho ntawm cov haujlwm tseem ceeb hauv lub voj voog tub yees.Rau cov khoom siv tub yees, vim qhov sib txawv me me ntawm lwm cov qauv tsim, condensing kub tuaj yeem hais tias yog qhov tseem ceeb tshaj plaws ntawm kev ua haujlwm, uas yog ncaj qha cuam tshuam rau lub tub yees, kev nyab xeeb, kev ntseeg siab thiab kev siv lub zog ntawm lub tub yees.

2. evaporation kub: evaporation kub yog hais txog qhov kub thiab txias thaum lub tub yees evaporates thiab boils nyob rau hauv lub evaporator, uas yog sib xws rau evaporation siab.evaporation kub kuj yog ib qho tseem ceeb parameter nyob rau hauv lub tub yees system.Qhov ntsuas kub evaporation feem ntau yog 2-3 ℃ qis dua li qhov xav tau dej kub.

Qhov ntsuas kub evaporation yog qhov zoo tshaj plaws ntawm lub tub yees, tab sis qhov tseeb evaporation kub yog 3 txog 5 degrees qis dua lub tub yees txias.

3. Yuav ua li cas los txiav txim qhov kub thiab txias condensation feem ntau: evaporation kub thiab condensation kub yog raws li qhov yuav tsum tau, xws li cua txias chav tsev, qhov condensation kub feem ntau yog nyob ntawm qhov kub thiab txias, thiab evaporation kub nyob ntawm seb dab tsi. koj siv rau, txawm tias nyob rau hauv qee qhov chaw kub, qhov yuav tsum tau evaporation kub yog qis dua.Cov kev ntsuas no tsis zoo ib yam, feem ntau pom cov kev siv tswv yim.

Thov xa mus rau cov ntaub ntawv hauv qab no:

Feem ntau,

dej txias: evaporation kub = dej txias qhov hluav taws xob kub -5 ℃ (dry evaporator)

yog tias tag nrho evaporator, evaporation kub = dej txias qhov hluav taws xob kub -2 ℃.

Condensation kub = dej txias qhov hluav taws xob kub +5 ℃

cua txias: evaporation kub = dej txias qhov hluav taws xob kub -5 ~ 10 ℃,

condensation kub = ambient kub +10 ~ 15 ℃, feem ntau 15.

Txias cia: evaporation kub = txias cia tsim kub -5 ~ 10 ℃.

Kev tswj qhov kub thiab txias: ua ntej peb yuav tsum paub tias qhov qis dua qhov evaporation siab, qhov kub ntawm evaporation qis dua.Kev tswj hwm qhov kub thiab txias, hauv kev ua haujlwm tiag tiag yog tswj cov evaporation siab, uas yog, kho cov nqi siab ntawm qhov ntsuas qhov ntsuas qis, kev ua haujlwm los ntawm kev kho lub thermal expansion valve (los yog lub valve) qhib los kho qhov tsis tshua muaj siab.Lub expansion valve qhib degree yog qhov loj, evaporation kub nce, qhov qis siab kuj nce, lub peev xwm txias yuav nce;Yog hais tias lub expansion valve qhib degree me me, qhov kub thiab txias evaporation txo, qhov qis siab kuj txo, lub peev xwm txias yuav raug txo.
