Until now, only EER (evaluation of the efficiency in cooling operation) and COP (evaluation of the efficiency in heating operation) were listed. These values were only designed for an individual measuring point.
The new SEER and SCOP performance indicators, however, define several measuring points that are all included in the classification. The "S" stands for "seasonal".
Measuring points in the cooling range:
This range covers outdoor temperatures of 20 °C, 25 °C, 30 °C, and 35 °C. For cooling operation, the climate data are accepted by Strasbourg as a representative for all of Europe.
The measuring points are weighted differently accordingly to the temperature curves.
Measuring points in heating operation:
No Europe-wide, uniform temperature profile was created for heating operation. A division has been made into three climate zones: northern, central, and southern Europe with different load profiles.
The measuring points are uniformly fixed at outside temperatures of 12 °C, 7 °C, 2 °C, and – 7 °C.
