Thaum tshav kub kub exchangers ua lub luag haujlwm tseem ceeb hauv kev tsim khoom, uas yog qhov tseem ceeb hauv cov hauv qab no:
1. Kev txuag hluav taws xob thiab txo kev siv hluav taws xob: cov khoom siv hluav taws xob txo qis kev siv hluav taws xob thiab txhim kho kev siv hluav taws xob los ntawm kev rov ua dua thiab siv cov khoom siv hluav taws xob pov tseg. Piv txwv li, hauv kev lag luam petrochemical, los ntawm kev rov ua dua thiab siv cov khoom siv hluav taws xob pov tseg thaum lub sij hawm cov txheej txheem tshuaj tiv thaiv, kev siv hluav taws xob thiab cov nqi tsim khoom tuaj yeem txo qis.
2. Txhim kho cov khoom zoo: cov khoom siv hluav taws xob tuaj yeem tswj tau qhov kub thiab txias kom ntseeg tau tias cov txheej txheem tsim khoom tau ua raws li qhov ntsuas kub zoo, yog li txhim kho cov khoom zoo. Piv txwv li, hauv kev lag luam tshuaj, los ntawm kev tswj xyuas qhov kub thiab txias los ntawm cov khoom siv hluav taws xob, cov khoom xyaw nquag ntawm cov tshuaj tuaj yeem ua kom tsis txhob raug puas tsuaj, yog li txhim kho cov tshuaj zoo.
3. Ua kom muaj kev nyab xeeb ntawm cov khoom siv: cov khoom siv hluav taws xob tuaj yeem hloov kho qhov kub thiab txias ntawm cov khoom siv los tiv thaiv cov cuab yeej los ntawm kev puas tsuaj vim overheating lossis overcooling. Piv txwv li, hauv kev lag luam hluav taws xob, cov khoom siv xws li cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob yuav tsum tau tswj xyuas qhov kub thiab txias kom ua haujlwm ruaj ntseg ntawm cov khoom siv thiab txuas ntxiv nws lub neej kev pab cuam.
4. Kev tiv thaiv ib puag ncig thiab txo qis emissions: cov khoom siv hluav taws xob txo cov cua sov ua kom muaj kuab paug rau ib puag ncig los ntawm kev rov ua dua tshiab thiab siv cov khoom siv hluav taws xob pov tseg. Tib lub sijhawm, qee qhov siab -kev ua tau zoo thiab lub zog- txuag cov khoom siv hluav taws xob kuj tuaj yeem txo cov pa hluav taws xob hauv tsev thiab ua rau muaj kev tiv thaiv ib puag ncig.
