Efficiency challenging the future: ErP 2018 ready
The European Regulation EU 2016/2281, known as ErP 2018, sets the new SEPR parameters for assessing the energy efficiency of chillers. The CyberCool 1 complies with the limits required by ErP 2018.
- E.E.R.: Energy Efficiency Ratio
Chiller efficiency at a certain condition.
- E.S.E.E.R.: European Seasonal Energy Efficiency Ratio
Seasonal efficiency of a chiller for comfort: ambient air from 25 to 35°C
- S.E.P.R.: Seasonal Energy Performance Ratio
Evaluates the load and temperature variations during the year,
relative to the chiller's electricity consumption.
