Nrog rau kev txhim kho thev naus laus zis, kev tsim thiab cov khoom siv ntawm cov khoom siv hluav taws xob hloov pauv tau txuas ntxiv ua kom zoo dua qub. Piv txwv li, cov qauv corrugated tshiab tsom txhawm rau txhim kho kev sib pauv hluav taws xob thaum txo qis kev ua haujlwm. Hais txog cov ntaub ntawv, daim ntawv thov ntawm cov ntaub ntawv sib xyaw lossis cov alloys tshwj xeeb nthuav qhov kev siv ntawm cov phaj kub exchanger. Kev txhim kho hauv kev tsim cov txheej txheem txhim kho qhov tseeb thiab sib xws ntawm daim hlau. Cov kev tsim kho no pab txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov phaj kub exchanger, ua tau raws li cov kev xav tau ntawm kev lag luam ntau dua.
Raws li cov khoom tseem ceeb, kev tsim, cov khoom siv, thiab kev saib xyuas ntawm cov phaj kub exchanger muaj qhov cuam tshuam loj rau kev ua haujlwm ntawm tag nrho cov cuab yeej. Kev xaiv thiab siv tau zoo tuaj yeem ua kom muaj txiaj ntsig thiab ruaj khov ntawm cov khoom siv hluav taws xob sib pauv. Hauv kev siv tswv yim, cov neeg siv yuav tsum xaiv qhov tsim nyog raws li lawv tus kheej xav tau thiab cov lus qhia tshaj lij.
