How to calculate the heat exchange area
Thread Content
This post was last edited by Taizhou Yijia on 2017-4-20 at 10:45. Given that the heat exchange area is 21 square meters, how can one determine the diameter of the heat exchanger, the length of the heat exchange tubes, and the number of such tubes? As shown in the image below, I’m really curious about how these values are determined. Does anyone know and can tell me? . . . . . . . . Thank you
Find the process calculation specialist at your company; he will be able to give you these answers once you tell him the heat exchange area.
Between the length of the heat exchange tubes and the number of such tubes, one must be determined first; only then can the other values be calculated based on the area.
The sequence of steps is generally as follows: given the diameter of the shell and the length of the heat exchange tubes, along with the specifications of those tubes, the task is to determine the heat exchange area; finally, the result is the layout of the tubes.
This really can’t be explained in just a couple of sentences; the basic parameters of this condenser are determined by the manufacturing process. For the equipment field, it’s a matter of strength; moreover, the heat transfer coefficient is calculated rather than looked up.
