On the series-parallel connection of heat exchangers in EDR
Thread Content
I would like to ask: in EDR heat exchangers, what does series and parallel connection refer to – the series and parallel arrangement of the tube side, or something else? If it refers to the pipe level, then how are the shells connected? Is it in series and parallel just like the pipe level, or are they all in parallel or something else?
I’m referring to the series and parallel connections within EDR. I am aware of how these work in practice, but in EDR, for example, if I choose 2 series connections and 3 parallel connections, with each unit designed to operate in counterflow mode, then how exactly are the series and parallel connections arranged in reality? Shell side, how is the flow rate distributed in the tube side?
EDR simulates heat exchangers – shouldn’t one first create the process in Aspen or some other simulation software? I’m not quite sure what you mean
This feature is available directly in EDR; there is no need to simulate it in Aspen first
It is a series connection of the tube side, with the shell side being separate; you can understand this by looking at the inlet and outlet temperatures and flow rates on the tube side and shell side as per the design.
