Ecodesign Lot 6 for non-residential ventilation units!

  1. All ventilation units, except fans with more than one range of application (for example fans used for both ventilation and combustion gas extraction) shall be equipped with a step-bystep or a variable speed controller.
  2. All ventilation units with two directions of airflow shall have a heat recovery system.
  3. The heat recovery system shall have a thermal bypass. This means heat recovery regulation between 1-100%.
  4. In ventilation units with two directions of airflow, the minimum thermal efficiency of all heat recovery systems (except run-around liquid systems) shall be the following: as from 1 January 2016: Min. 67% and as from 1 January 2018: Min. 73%.
  5. In ventilation units with two directions of airflow, the minimum thermal efficiency of run-around liquid heat recovery systems shall be the following: as from 1 January 2016: Min. 63% and as from 1 January 2018: Min. 68%.
  6. The ratio between specific fan power (SFPint ) and the heat recovery system’s efficiency is specified in a formula. If the efficiency on heat recovery for example is higher than 67%, a higher specific fan power (SFPint ) is permissible. This requirement will be implemented in two steps. The first step will be implemented on 1 January 2016, and the second, with more stringent demands, on 1 January 2018.
