Air-side Development of Evaporator Unit

Workpackage 7: Air-side Development of Evaporator Unit

The WP 7 involves the Design, assembly and test rig characterization of the complete evaporator unit

  1. Significantly enhancing the knowledge of the condensation and subsequent icing processes in combinations of heat exchanger packages and fans based on velocities, relative humidity and temperature conditions;
  2. Development and application of numerical condensation and icing models for all air-touched parts in the evaporator unit;
  3. Development and investigation of a new fin design for micro channel HEXs used in evaporators;
  4. Investigation of new concepts for high performance axial fans with optimized airflow system enabling low energy demand and low noise emissions.
