During a dedicated specialist forum at the Chillventa 2016 on 11 October in Nuremberg, the Eurovent association has released Eurovent 9/12. This industry recommendation constitutes the first European thermal performance efficiency standard for evaporative cooling equipment (cooling towers).
The document has been developed over the past 14 months in a joint effort by 10+ leading European cooling tower manufacturers within the Eurovent Product Group ‘Evaporative Cooling Equipment’ (PG-CT). The specialist forum during the Chillventa introduced, amongst others, the background, scope and outline of the new performance and efficiency rating standard, thermal energy efficiency definitions and targets, thermal testing and uncertainty calculations, and tools for an effective efficiency verification.
Eurovent 9/12 applies to mechanical draught evaporative cooling products, which transfer heat of the atmosphere primarily by the evaporation of water (latent heat transfer). Mechanical draught evaporative products include open wet cooling towers as well as closed-circuit cooling towers and evaporative condensers in the forced and the induced draught configuration using either axial or centrifugal fans.
‘As a response to the ongoing revision of the EU Fan Regulation, which so far does not rightly account for thermal efficiencies, and as a reaction to the ongoing discussion throughout Europe on cooling tower efficiencies, we are happy to present a joint industry response as a first major step to tackle these issues.’ States Georg Mager, Senior Project Manager Evaporative Cooling at the Eurovent association. ‘The major players of this industry have jointly developed a Eurovent standard, which sets strong minimum thermal energy efficiency targets underlining their energy efficiency ideals.’
The Eurovent Product Group ‘Evaporative Cooling Equipment’ is Europe’s largest working group dedicated to evaporative cooling equipment and home to all leading European manufacturers. Eurovent’s independent subunit Eurovent Certita Certification is in parallel running a ‘Eurovent Certified Performance’ scheme for cooling towers in cooperation with CTI (Cooling Technology Institute) in the USA – ensuring that the published efficiency data matches the real performance.
Eurovent 9/12 is available for download free-of-charge at the online document shop of the Eurovent association website.
