The thermal production equipment, chillers and heat pumps, have had a huge technological evolution in recent years. On the other hand, the legal framework during the same period and the respective classes of energy efficiency have undergone great change. 

The aim of this technical-themed afternoon was to promote a knowledge update on these subjects, particularly focusing on the following aspects:
• Eurovent certification;• European standard EN14511: 2013;
o Calculation method;
o Energy efficiency classes (EER, ESEER);
• Efficiencies at partial loads (scroll, screw and inverter compressors);
• Multifunctional unit with 4 tubes;
• Units with free - cooling.

The technical session was presented by the engineer, Roberto Bernabei, of BlueBox.
