What should be noted when feeding data into a standard HTRI heat exchanger?
Thread Content
I would like to ask experts: what should be paid attention to when entering data for standard heat exchanger calculations using HIRT? Why are the heat exchange area values I calculate different from those of standard heat exchangers?
Dirt thermal resistance? What’s the value of K?
I’m referring to piping; why is the heat exchange area of the main pipe always different from that of standard heat exchangers?
It’s very simple – it’s just a calculation of the area of the outer diameter of the pipe. Check it yourself; it’s normal for the results to differ, as different calculation methods may be used. In standard heat exchangers, the values are often rounded off
