Vapor Cycle Library (VCL)🔗

The Vapor Cycle Library, or the VCL, is intended for the steady-state and dynamic analysis of vapor compression cycles. Typical tasks are component selection, system performance optimization and verification and also control design and verification. The library can be used to analyze partial as well as complete cycles. Models are designed in a way that is similar to the structure of real thermodynamic cycle assemblies.

Heat Exchanger Library (HXL)🔗

The Heat Exchanger Library, or the HXL, is intended for the heat-exchanger design, dimensioning, and stacking. The library contains heat exchanger models supporting several flat-tube, louvered fin and plate designs. Users can simulate inhomogeneous airflow, temperature distribution and heat-exchanger stacking along the airflow path. The library is suitable for studying the effects of heat exchanger dimensioning and positioning on cooling performance. Heat Exchanger Library has native interfaces to Air Conditioning Library, Vapor Cycle Library, and Liquid Cooling Library for complete thermal management design. The models can be coupled to CFD-derived boundary conditions on the air side, bridging the gap between CFD and system simulations.

Key features involve
  • Geometry based heat exchanger models for system simulations,
  • Friction and heat transfer models for louvered fin designs,
  • Capture effects of inhomogenously distributed inlet air flow,
  • Coupling to CFD data, and
  • Modeling of heat exchanger stacks with different heat exchanger geometries, sizes and positioning.
Key concepts to use Heat Exchange Library (HXL)

Below is the list of parameter groups/tabs which helps the user to understand the geometry parameters:

  • Flow Design and Outer Dimensions parameter group contains the parameters which defines the heat exchanger tube orientation, refrigerant flow direction, flow scheme, flat tubes and outer dimensions.
  • Fin Rows parameter tab contains the parameter which defines the number of external fins rows
  • Channel Geometry parameter tab contains the parameter which defines the channel geometry parameters and designs
  • Fin Geometry parameter tab contains the parameter which defines the fin geometry parameters and designs
  • Receiver Geometry parameter tab contains the parameter which defines the receiver geometry parameters
