Saib xyuas qhov kub thiab txias sab nraud ua ntej thiab tom qab hloov pauv
Xaiv qee qhov chaw saib xyuas kom txuag hluav taws xob Kev rwb thaiv tsev kub kev hloov pauv ntawm cov khoom siv thermal thiab cov kav dej, thiab ntsuas qhov kub sab nraud ntawm cov ntsiab lus saib xyuas ua ntej thiab tom qab kev hloov pauv. Tom qab ua tiav kev rwb thaiv tsev thiab kev hloov pauv txuag hluav taws xob, qhov kub ntawm cov khoom siv tau ua raws li cov qauv tsim nyog, thiab kev rwb thaiv tsev kub thiab kev txuag hluav taws xob ntawm cov khoom siv cua sov thiab cov kav dej tau txhim kho zoo heev kom ua tiav cov kev cai rwb thaiv tsev thiab txuag hluav taws xob.

Ua ntej lub qhov kaw tsis raug rwb thaiv tsev, qhov kub ntawm qhov chaw yog 371 Fahrenheit, uas yog sib npaug rau 188.44 Celsius, raws li pom los ntawm lub koob yees duab.

Tom qab lub qhov kaw tau raug rwb thaiv tsev thiab ua haujlwm tau 10 hnub, qhov kub ntawm qhov chaw yog 119 Fahrenheit, uas sib npaug rau 48.3 Celsius, raws li lub koob yees duab pom.

Kev sib piv ntawm cov cua sov poob ua ntej thiab tom qab kev hloov kho
Kev siv q (W/m2) qhia tau hais tias qhov kub thiab txias ntawm cov cua sov, qhov ntau ntawm cov cua sov uas tsim los ntawm thaj chaw yog qhov poob cua sov thiab cov khoom ntawm thaj chaw, thiab thaj chaw ntawm qhov xwm txheej rwb thaiv tsev muaj kev sib raug zoo nrog kev kuaj pom cov khoom siv thermal thiab cov nyhuv rwb thaiv tsev thermal ntawm cov kav dej, qhov ntsuas yog qhov qhia tseem ceeb ntawm cov nyhuv ntawm kev tshuaj xyuas cov khoom siv thermal thiab cov kav dej. Nws muab tus nqi siab tshaj plaws ntawm kev poob cua sov uas tso cai rau cov khoom siv thermal thiab cov kav dej hauv qab qhov kub sib txawv.
q=a×(TW-TF)
q qhia txog qhov kub poob/qhov kub ntws ceev, (W/m2) cylindrical phab ntsa pipeline nto cua sov hloov system a=9.42+0.05×(TW-TF)W/(m2-K); TW qhia txog qhov kub sab nraud ntawm Kev rwb thaiv tsev Sqauv; TF qhia qhov kub thiab txias ib puag ncig.

Tom qab txhim kho lub tes tsho rwb thaiv tsev, qhov hloov pauv kub ntawm cov khoom feem ntau yuav qeeb qeeb, uas tau pom hauv cov xwm txheej hauv qab no:
Rau cov khoom kub siab: xws li khiav cov khoom siv kev lag luam, cov kav dej kub siab, thiab lwm yam, tus Lub Tes Tsho Rwb Thaiv Kub tuaj yeem txo qhov cua sov poob rau ib puag ncig. Vim tias lub tes tsho rwb thaiv tsev thermal muaj qhov thermal conductivity qis, tuaj yeem cuam tshuam qhov cua sov los ntawm kev conduction thiab convection mus rau lub ntiaj teb sab nraud, yog li ntawd qhov kub poob ntawm cov khoom qeeb qeeb, kom tswj tau qhov kub siab dua, txo qhov cua sov poob, thiab txhim kho kev siv hluav taws xob zoo.
Rau cov khoom kub qis: xws li cov thoob dej txias qis, kev thauj khoom txias, thiab lwm yam, qhov thermal Lub tsho rwb thaiv tsev tuaj yeem tiv thaiv kev hloov pauv cua sov sab nraud. Qhov no tuaj yeem ua rau cov khoom kub qis qis dua, txo qhov poob ntawm qhov txias, thiab tiv thaiv lawv qhov kub kom tsis txhob nce sai dhau thiab cuam tshuam rau qhov zoo ntawm cov khoom, piv txwv li, tiv thaiv cov khoom noj hauv cov saw hlau txias kom tsis txhob puas tsuaj vim qhov kub nce.
Rau cov khoom lossis ib puag ncig uas qhov kub yuav tsum tau tswj kom ruaj khov: piv txwv li, qee cov khoom siv hauv chaw kuaj mob thiab cov cuab yeej hluav taws xob uas xav tau qhov kub kom raug, lub tsho rwb thaiv tsev thermal pab tswj kom qhov kub ruaj khov. Nws tuaj yeem txo qhov cuam tshuam ntawm qhov kub thiab txias sab nraud ntawm cov khoom, yog li qhov kub ntawm cov khoom nyob rau hauv ib qho ntau yam kom tswj tau qhov kub tas li, uas pab txhawb kev ua haujlwm ib txwm ntawm cov khoom siv thiab qhov tseeb ntawm cov txiaj ntsig sim.
