Ecodesign regulation 2016 / 2281 also applies to High Temperature Process Chillers with rated cooling capacity below 2,000 kW for industrial process applications . High temperature chillers are capable of delivering leaving water temperatures of between 2 ° C and 12 ° C . In addition regulation 1095 / 2015 affects any capacity Process Chillers operating at design capacity that can generate outlet fluid temperature of -8 ° C ( Medium Temperature ).
SEPR - Seasonal Energy Performance Ratio
Ecodesign regulation 2016 / 2281 and 1095 / 2015 introduces a new indicator called Seasonal Energy Performance Ratio ( SEPR ), which is the ratio of annual cooling demand to annual electrical energy consumption .
SEPR is calculated from an average climate reference with ambient temperature ranging from -19 ° C up to 38 ° C , and with corresponding operating hours at each temperature bin . For Process cooling the operating load ranges from 100 % down to 80 %.

Efficiency requirements set by REGULATION 2016 / 2281 High Temperature Process Chillers
Regulation 2016 / 2281 sets minimum efficiency levels for positive leaving water temperature chillers ( high temperature chillers ) rated up to 2,000 kW used in industrial process cooling applications . There is no SEPR HT requirement for chillers and heat pumps that apply to other regulations .

Efficiency requirements set by REGULATION 1095 / 2015 Medium Temperature Process Chillers
Regulation 2015 / 1095 sets minimum efficiency levels for chillers with negative leaving water temperature used in industrial process cooling applications . Medium temperature process chillers are defined as units capable of operating at -8 ° C leaving temperature . Chillers that applies to this regulation ( SEPR MT ) are excluded to the other Ecodesing regulations ( like 2016 / 2281 )
