The ErP Directive
The European Union is setting ambitious targets for climate protection with the ErP Directive. Compared to 1990 levels, the 20/20/20 energy policy aims to achieve the following by 2020:
- 20% reduction of greenhouse gas emissions
- 20% increased use of renewable energies
- 20% reduction of CO2 emissions
ErP stands for Energy related Products and specifies the framework conditions & minimum requirements of different groups of energy-consuming products. This includes the regulation of energy consumption and permitted sound power levels:
- Lot 10 applies to room air conditioner units with a cooling capacity up to 12 kW
- Lot 1 applies to heat pumps with a heating capacity up to 400 kW
These regulations came into force in 2013 and almost every consumer can be identified by its EU energy label. All values are documented on this label and allow for easy comparison, so that a high-quality product can be recognized at the first glance. Furthermore, every manufacturer or importer must make their data accessible in brochures and on their website. You can find the link to the Ecodesign website below.
Questions and Answers
Air conditioning systems have been established for a long time in the private sphere. More and more home and apartment owners are relying on the comfort of pleasant cooling.
Due to innovative technologies, many of the air conditioners available, for example from TOSHIBA, are highly efficient. Room air conditioner units can even better differentiate themselves regarding their economic efficiency due to the new ErP Directive.
The suppliers of inefficient units will lose their market access.
Starting January 2013, the scale of energy efficiency class A was expanded with classes A+, A++, and A+++.
In addition, the classification now also takes into account the noise emission (sound power level of the indoor and outdoor units).
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.
Climatic conditions have a major influence on the performance of air conditioning systems in heat pump mode. Therefore, this is divided into three zones within the EU:
Northern Europe: cold
Central Europe: medium
Southern Europe: warm
The ErP Directive for room air conditioner units (lot 10) took effect on Jan 1, 2013 and is valid in all countries of the EU without any national transitional periods.
