Counter flow heat exchangers yog qhov muaj txiaj ntsig ntau dua li qhov sib npaug ntawm cov khoom siv hluav taws xob sib txuas vim tias lawv tsim qhov sib txawv ntawm qhov sib txawv ntawm cov kua dej, dhau tag nrho qhov ntev ntawm cov kua dej.
Hom dej twg yog hom ntws zoo tshaj?
Counter flow heat exchangers yog qhov ua tau zoo tshaj plaws ntawm peb hom. Nyob rau hauv sib piv rau parallel flow heat exchanger, lub counter flow heat exchanger tuaj yeem muaj qhov kub tshaj plaws txias-kua dej kub siab tshaj qhov txias tshaj plaws kub-kua kub.
Qhov twg ntws zoo dua hauv cov khoom siv hluav taws xob?
Qhov twg ob lub kua yuav tsum tau coj mus rau qhov kub thiab txias, parallel flow configuration yog qhov zoo. Thaum lub txee ntws kub exchanger muaj ntau qhov zoo dua piv rau cov qauv sib npaug.
Puas countercurrent flow efficient?
Los ntawm qhov sib piv, txee ntws yog qhov ua tau zoo duathiab, nyob ntawm tus nqi ntws thiab qhov kub thiab txias, kev ua haujlwm kub hloov mus txog 15% ntau dua, muaj peev xwm ua tau Cov khoom siv hluav taws xob me me los siv, txuag chaw thiab nyiaj txiag!
Vim li cas qhov ntsuas tam sim no zoo dua?
Qhov siab tshaj plaws ntawm cov cua sov lossis huab cua hloov pauv uas tuaj yeem tau txais yog siab dua nrog cov khoom sib txawv dua li kev sib pauv tam sim no (parallel) vim countercurrent tswj qhov sib txawv qeeb qeeb lossisgradient (feem ntau yog qhov kub thiab txias sib txawv).
