The activity of the work group (JWG) for drafting the new regulation on the minimum efficiency of cold water pumps<\/strong> (MEI), a group Calpeda has been involved in through its experts Michele Dai Pr\u00e8 and Andr\u00e8 Kistner, is continuing.<\/p>\n

The work, which started in 2012 as part of the larger EC Regulation 547\/2012 which establishes the specifications for the eco-friendly design of water pumps<\/strong>, has already conveyed the identification of minimum efficiency values: MEI>0.1, which entered into force in January 2013, and MEI>0.4, which entered into force in January 2015.<\/p>\n

The progress of the increase in the MEI indexes fixed by the Regulation has been respected and is operative.<\/p>\n

Currently, the group is already working on additional objectives regarding energy efficiency<\/strong>.\u00a0 In the next few years we can expect the introduction of new indexes which will probably involve even swimming pool pumps and drainage pumps.\u00a0 But that is not all.\u00a0 These new objectives are tied to a changed calculation philosophy<\/strong> that will no longer be MEI, but which will become EEI<\/strong> (Energy Efficiency Index), as established for the circulators.<\/p>\n

In substance, the EEI is the result of an Extended Product Approach<\/strong>, in other words a wider approach according to which the product is considered in its entirety (pump, motor and possible frequency converter):\u00a0 As a result, even the minimum efficiency value will no longer be given by summing the minimum efficiency values requested for the single components, but will be a total\/unified value.<\/p>\n

This new approach will bring additional energy saving<\/strong>, necessary for reaching the objective of reduced CO2 emission established by the European Union.\u00a0 It has indeed been noted that this goal will be difficult to reach by only increasing the efficiency of every single component; the union of very efficient components, in fact, does not necessarily produce a highly performing system.\u00a0 The solution proposed by the Europump JWG is to add EEI values according to the application, to try and direct the installer or end client to a system that is more efficient for their installation.<\/p>\n
