ENTR Lot 1 – Professional Refrigeration (Process Chillers brine)
Published regulation 1095/2015 affects all Process Chillers operating at design capacity that can generate outlet fluid
temperature of -25°C (Low Temperature) or -8°C (Medium Temperature).
High Temperature Process Chillers operating at design capacity that can generate outlet fluid temperature of 7°C are
part of ENER Lot 21.
A new KPI
Ecodesign regulation 1095/2013 introduces a new indicator called Seasonal Energy Performance Ratio (SEPR), which is
the ratio of annual cooling demand to annual electrical energy consumption.
At this time there is no EN specification to base the SEPR calculation on. The calculation is currently based on the
“Transitional method for determination of SEPR for industrial process chillers”, published with the regulation.
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%.
A better Indicator
SEPR is a better performance indicator for process cooling, as it accounts for year round, high load profile operation typical of
process cooling applications.
The graph on the left and below displays the distribution of temperature bins and hours used by the regulation as a climate
reference. This climate reference is based on weather data from cities throughout central Europe.
The graph on the right and below displays rating points that are part of the SEPR and SEER calculations. Note that SEPR
is focused on high loads (typical of process cooling applications) and SEER is focused on variable loads (typical of comfort
applications).

Bonus for units using Low Global Warming Potential (GWP) refrigerants
As detailed in the table below, regulation 1095/2015 adjusts the Minimum Energy Performance Standard (MEPS) based on the
GWP of the refrigerant used.
