# Commission Regulation (EU) 2016/2281 of 30 November 2016 implementing Directive 2009/125/EC of the European Parliament and of the Council establishing a framework for the setting of ecodesign requirements for energy-related products, with regard to ecodesign requirements for air heating products, cooling products, high temperature process chillers and fan coil units (Text with EEA relevance), Division 5: Seasonal space cooling energy efficiency of comfort chillers and air conditioners using internal combustion engine:

Extent: E+W+S+N.I.

(a)The seasonal space cooling energy efficiency ηs,c shall be calculated on the basis of the seasonal primary energy ratio in cooling mode SPERC, corrected by contributions accounting for temperature control and, for water/brine-to-water comfort chillers, or water/brine-to-air air conditioners only, the electricity consumption of ground water pump(s);
(b)The seasonal primary energy ratio in cooling mode SPERC shall be calculated on the basis of seasonal gas utilisation efficiency in cooling mode SGUEC , the seasonal auxiliary energy factor in cooling mode SAEFC taking into account the conversion coefficient for electricity CC;
(c)The seasonal gas utilisation efficiency in cooling mode SGUEC shall be based on the part load for cooling Pc (Tj ) divided by the bin-specific gas utilisation efficiency for cooling at partial load GUEc,bin , weighted by the bin-hours the bin conditions occurs, using the conditions set out in point 5(h);
(d)The SAEFC shall be based on the reference annual cooling demand QC and the annual energy consumption for cooling QCE ;
(e)The reference annual cooling demand QC shall be based on the design cooling load Pdesign,c multiplied by the equivalent active mode hours for cooling HCE as set out in Table 29;
(f)The annual energy consumption for cooling QCE shall be calculated as the sum of:
(1)the ratio of the reference annual cooling demand QC and the seasonal auxiliary energy factor in cooling mode in active mode SAEFc,on ; and
(2)the energy consumption during standby, thermostat-off, off and crankcase heater mode during the season;
(g)The SAEFc,on shall be based (insofar as relevant) on the part load for cooling Pc (Tj ) and the auxiliary energy factor in cooling mode at partial load AEFc,bin , weighted by the bin-hours the bin conditions occurs using the conditions set out below;
(h)The conditions to calculate the SGUEc and the SAEFc,on shall take into account:
(1)the reference design conditions set out in Table 24;
(2)the European average cooling season set out in Table 27;
(3)if applicable, the effects of the degradation of the energy efficiency caused by cycling depending on the type of control of the cooling capacity.
