This course gives an Introduction to the Heat Exchanger Library, its contents and application areas, and how to work with it. The course teaches how to set up, configure and calibrate heat exchanger models. It also gives the insight required to efficiently use heat exchanger models in large-scale system models.

The course covers the following topics:

Library applications and overview

  • What is HXL?
  • Detailed geometry based heat exchangers
  • Flat tube geometry
  • Louvered fins
  • Liquid temperature distribution in flow direction
  • Inhomogeneous air flow distribution
  • Example uses

Library contents

  • Multiple layer and passes
  • Wall model
  • Air side interface (2D discretized connector)
  • Air flow assumptions
  • Simple experiment, single HX with some inflowing distribution

Working with the library

  • Stacking in air flow direction
  • Spatial resampling of air representation
  • Stacking where HX outer edges do not match

Who should attend?

This course is for users who want a comprehensive introduction in working with the Heat Exchanger Library. Previous knowledge about Dymola corresponding to Dymola Introduction Course, Part I is assumed.
