Kev xaiv ntawm cov phaj kub exchanger flow rate tuaj yeem ua rau muaj kev cuam tshuam tseem ceeb ntawm kev hloov hluav taws xob, kev siv hluav taws xob, thiab cov nqi khiav lag luam.Hauv qab no peb yuav qhia meej txog cov kev ceev faj thaum siv lub phaj kub exchanger ua condenser thiab evaporator.
1. Feem ntau, ob qho tib si condensation thiab boiling tuaj yeem ua tiav hauv ib txheej txheem.Yog li ntawd, cov theem hloov pauv feem ntau yog txheej txheem ib zaug, thiab cov kua sab tuaj yeem npaj tau raws li ib qho dhau los lossis ntau dhau raws li xav tau.Hauv thaj chaw ntawm HVAC thiab tub yees, sab dej feem ntau yog ib qho txheej txheem.
2. Rau cov phaj condensers, feem ntau tsis tso cai rau seem condensation thiab subcooling seem kom coexist thaum tsim.Vim tias qhov kev sib pauv cua sov ntawm qhov subcooling yog qhov tsawg, yog tias xav tau subcooling, hauv txoj cai, yuav tsum tau nruab ib lub subcooler cais.
3. Kuj tseem muaj qhov tso cai rau kev poob siab hauv kev tsim cov phaj condensers thiab evaporators.Lub siab loj poob rau hauv lub condenser yuav txo qhov condensation kub ntawm lub chav, ua rau ib tug me me logarithmic nruab nrab kub sib txawv;ib tug loj poob siab nyob rau hauv lub evaporator yuav ua rau kom lub superheat ntawm lub qhov hluav taws xob chav.Ob leeg yuav ua rau thaj tsam ntawm lub tshav kub exchanger, uas yog teeb meem rau qhov teeb meem.Thaum tshav kub kub pauv yog qhov tsis zoo.Yog li ntawd, thaum xaiv lub phaj evaporator, koj yuav tsum sim xaiv cov phaj nrog me me tsis kam, thiab tus naj npawb ntawm cov phaj yuav tsum tsis txhob ntau dhau;sim faib cov kua dej sib npaug.Phaj condensers yuav tsum siv qhov nruab nrab muab faib ua kua rau ob sab.
4. Thaum xaiv, cov qauv ntawm cov phaj condenser thiab phaj evaporator yuav tsum tau muab qhov tseem ceeb.Yog tias tsis muaj tus qauv tsim nyog, feem ntau siv cov phaj kub hloov pauv tuaj yeem xaiv tau.
5. Rau phaj kub exchangers siv nyob rau hauv lub tub yees thiab cov khoom cua txias, vim lub siab refrigerant siab thiab muaj zog to, yuav tsum tau siv brazed phaj kub exchangers.
Cov teeb meem uas yuav tsum tau them sai sai rau thaum siv phaj kub exchangers raws li condensers thiab evaporators yog cov ntsiab lus saum toj no.Cov neeg siv uas yuav cov phaj kub hloov pauv rau lub hom phiaj no yuav tsum tau them nyiaj tshwj xeeb rau cov teeb meem saum toj no thaum siv, kom ua kom nws tuaj yeem ua kom zoo tshaj plaws ntawm cov phaj hloov pauv, txo cov peev txheej engineering, thiab xyuas kom meej tias nws lub neej kev pab cuam tsis cuam tshuam.
