Lub phaj kub exchanger muaj ib tug me me ntim thiab high tshav kub hloov efficiency. Hom phaj yog tsim los rau cov kua-kua hluav taws xob hloov pauv, yog li nws tuaj yeem siv los ua lub condenser yam tsis muaj kev hloov kho, thiab cov txiaj ntsig kev sib hloov cua sov kuj zoo dua li cov raj hom. Txawm li cas los xij, thaum siv phaj kub exchangers ua evaporators thiab condensers ntawm lub tub yees thiab cua txias cua kub twj tso kua mis, cov teeb meem hauv qab no yuav tsum tau xav txog:
1. Feem ntau, condensation thiab boiling tuaj yeem ua tiav hauv ib txheej txheem. Yog li ntawd, cov theem hloov sab feem ntau yog teem rau hauv ib qho txheej txheem, thiab cov kua sab tuaj yeem npaj tau raws li ib txoj kev lossis ntau dhau raws li xav tau. Hauv thaj chaw ntawm HVAC tub yees, sab dej feem ntau kuj yog ib qho txheej txheem.
2. Rau phaj condensers, tsis txhob cia qhov condensing seem thiab subcooling seem ua ke. Vim tias qhov kev sib pauv cua sov tsawg ntawm cov ntu subcooled, yog tias xav tau subcooling, lub subcooler yuav tsum tau muab rau hauv txoj cai.
3. Kuj tseem muaj teeb meem poob siab hauv kev tsim cov phaj condensers thiab evaporators. Lub siab loj poob rau hauv lub condenser yuav txo qhov kub ntawm lub hws ntawm lub chav, uas ua rau ib tug me me logarithmic txhais tau tias kub sib txawv; Kev poob siab loj hauv lub evaporator yuav ua rau muaj kev kub ntxhov ntawm lub qhov hluav taws xob, ob qho tib si yuav ua rau thaj tsam ntawm lub phaj kub exchanger.
Yog li ntawd, thaum xaiv lub phaj evaporator, nws raug nquahu kom xaiv cov phaj uas muaj kev tiv thaiv qis kom ntau li ntau tau, thiab cov phaj ntawm ib phaj yuav tsum tsis txhob ntau dhau. Sim kom ntseeg tau tias txawm tias cov kua dej. Lub phaj condenser yuav tsum siv qhov chaw nruab nrab kom cais cov kua ntawm ob sab.
Thaum xaiv hom, hom qauv ntawm phaj condenser thiab phaj evaporator yuav tsum nyiam dua. Yog tias tsis muaj tus qauv tsim nyog, feem ntau siv universal phaj kub exchangers tuaj yeem xaiv.
Rau phaj kub exchangers siv nyob rau hauv lub tub yees thiab cua txias khoom, vim siab refrigerant siab thiab muaj zog to, yuav tsum tau siv brazed phaj kub exchangers.
Cov ntsiab lus saum toj no yog cov teeb meem uas yuav tsum tau muab sau tseg thaum siv phaj kub exchangers ua condensers thiab evaporators.
