UNILAB Coils User Manual

Without Fins

We have added (only in the ENTERPRISE Version) a possibility to calculate coils without fins, available in all the calculation modalities. The applications of this typology of coils are a lot, both on low and high temperatures (recuperator gas-gas both mono and multi crossing, painting rooms, coils for fluids with considerable filth level, or with transportation of dust and strips of paper, fabric, etc.). With this system you can simulate the shell and tubes with non circular plate, but rather rectangular or quadrangular.

Let’s see an example of the DX-evaporator without fins (with smooth tubes).

Let us see the details of the geometry of this heat exchanger:

We see that there is no information about the fins and the selected tube is smooth.
