Application of the new EN14511 : 2011 chiller and heat pump performance standard:
Chiller and heat pump performances are calculated in accordance with the EN14511 : 2011 calculation standard and certified by Eurovent.
The latest version of EN14511 was ratified on July 19th, 2011. It uses a different method to take into account the contribution of water pumps, or heat exchanger pressure drops in the unit performances. The efficiency of
the pump is no longer a default value, but a function of the required hydraulic power. In January 2012, the Eurovent Certification Company decided that this method is more realistic and it is fully applied starting
from the 2012 certification campaign. The performances declared based on the new version of the standard were published on the ECC website www.eurovent-certification.com at the end of March 2012.
IMPORTANT: Only 2012 performances rated according the new EN14511 : 2011, taking in account water pump and heat exchanger pressure drop are certified by Eurovent. For units declared before 2012, the
previous gross EER and COP values without pump correction (for units with integral pump - measured with the pump not running) and the corresponding energy classes are available on ECC website.
