Lub tshuab hluav taws xob hluav taws xob yog ib qho khoom siv uas hloov qee qhov cua sov los ntawm cov kua dej kub mus rau cov kua dej txias; nws tseem hu ua lub tshav kub exchanger. Thaum tshav kub kub exchangers ua lub luag haujlwm tseem ceeb hauv tshuaj lom neeg, roj av, hluav taws xob, khoom noj khoom haus, thiab ntau lwm cov txheej txheem tsim khoom. Hauv kev tsim tshuaj lom neeg, cov khoom siv hluav taws xob tau siv dav hauv cov cua sov, txias, condensers, evaporators, thiab reboilers.
1. Lub tshuab cua sov ua kom sov cov kua dej rau qhov ntsuas kub uas tsim nyog, tab sis cov kua cua kub tsis dhau ib theem hloov.
2. Lub preheater preheats cov kua dej, muab cov txheej txheem txheej txheem rau kev ua haujlwm.
3. Lub superheater yog siv los ua kom sov cov kua dej (cov txheej txheem roj los yog chav dej) mus rau lub xeev superheated.
4. Ib qho evaporator heats cov kua rau qhov kub siab tshaj qhov kub ntawm qhov kub, ua rau cov kua evaporate; Qhov no feem ntau cuam tshuam nrog kev hloov theem.
