EER Correction: Chillers w/o Modulation Part load EER for chillers (compressors) w/o capacity modulation: Calculation according to EN 14825 Degradation Coefficient (Cd), (Cdc) at part load (CR = capacity ratio): Cdc can be determined by test (EN 14825) A/C Chillers incl. power demand of all auxiliaries during standstill (e.g. oil heater). If not to be determined by test Cdc = 0,9 Process Chillers: Due to very high running hours over the year, power demand for oil heaters is not relevant for Cdc Schaffhausen, 25 th / 26 th June, 2015 Page 16

ENTR Lot 1 / ENER Lot 21 Status Following slides are showing the current status of minimum efficiency requirements (MEPS) Process Chillers: MEPS are accepted by Commission Officials and Stakeholders and will most likely not be changed in the final Regulation Comfort A/C Chillers: Very challenging (some non-plausible) MEPS were not lowered during the current Inter-service Consultation Process despite of convincing counter proposals from Stakeholders at an earlier stage Further initiatives are taken with the target to reach a consensus with the hope that MEPS (at least for Tier-1) will be changed Schaffhausen, 25 th / 26 th June, 2015 Page 19
