# 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), Annex III: Measurement and calculation

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

For establishing the values of rated and declared cooling capacity, power input, energy efficiency ratio and the seasonal energy performance ratio, measurements shall be done using the following conditions:
(a)the reference ambient temperature at the outdoor side heat exchanger shall be 35 °C for air-cooled high temperature process chillers and 30 °C water inlet temperature to the condenser (rating point with 35 °C outdoor air temperature) for water-cooled high temperature process chillers
(b)the outlet temperature of the liquid at the indoor side heat exchanger shall be 7 °C dry bulb temperature;
(c)the variations of the ambient temperature throughout the year, representative of average climate conditions in the European Union, and the corresponding number of hours when these temperatures occur, shall be as set out in Table 28;
(d)the effect of the degradation of energy efficiency caused by cycling depending on the type of capacity control of the high temperature process chiller shall be measured or a default value shall be used.
Table 16
Standard rating conditions for air-to-air heat pumps and air conditioners
The wet bulb temperature condition is not required when testing units which do not evaporate condensate.
