Description
Heat exchanger / module package AC
Possible combinations at a glance
The program considers multi-pass bundles and shells. Tube pitch and arrangement are freely selectable. A variety of tube geometries is included: Plain tubes, circular, spiral and rectangular fins, lamellas, internal fins, twisted tube inserts, corrugated tubes. Shells may be round or rectangular. Free input of properties is possible.
More options:
Calculation of condensation processes (complete or partial) around the tubes and in the tubes.
Calculation of evaporation processes of pure substances (complete or partial) in the tubes
Calculation of cooling of air or flue gas with condensing humidity
