Our use of energy is changing. From the perspective of European legislation too. The ErP Directive ensures that 'Energy-related Products' have to be clearly labelled.

This page explains the key content of the ErP Directive in relation to air conditioning technology and heat pumps.

We can help you find the right solution, regardless of whether you wish to efficiently heat or cool – to meet your needs and also conserve the environment. Shape the future with us!

THE EUROPEAN UNION IS SETTING HIGH TARGETS

The European Union is pursuing ambitious climate protection targets, with important milestones to be reached by 2020 compared to 1990:

20%
Lower use of primary energy
20%
More renewable energy
20%
Fewer CO2-emissions

THE ERP OR ECODESIGN DIRECTIVE

It is against this background that the EU introduced the ErP Directive, which is intended to support and advance the resource-conserving, energy-efficient design of energy-related products. The ErP Directive applies to products that meet the following criteria:

  • Minimal annual sales in the EU of 200,000 products
  • Major impact on the environment
  • Significant potential for improving environmental tolerability at reasonable cost

From televisions and refrigerators to heaters and air conditioning units, a wide range of products and technologies correspond to these criteria.

In order to formulate product-specific stipulations, there is a further division into product groups and associated implementation measures known as lots. Multiple lots may apply to a single unit depending on its function. Lot 1, Lot 2, Lot 6, Lot 10 and Lot 21 are relevant for products from Mitsubishi Electric.

The provisions of the ErP Directive

The ErP Directive is based on two implementing regulations: the Ecodesign Directive for CE labelling and the Energy Labelling Directive.

CE- LABELLING

CE-LABELLING

The Ecodesign Directive defines so-called minimum efficiency and minimum emission standards. Products that do not meet these standards are not awarded CE marking and may no longer be imported into the EU. This required manufacturers, above all, to work with technologies that are CE compliant, now and in the future.

Energy- LABELLING

Energy-Labelling

The Energy Labelling Directive sets out how the Energy Labels should look. It defines which values are needed for classification in a specific efficiency class. The labels are intended, above all, to help consumers to compare products and select them based on their efficiency. Units that feature a higher capacity for use in the commercial sector do not need to be identified with a label.

SEASONAL MEASUREMENT CRITERIA FOR COOLING AND HEATING MODES

Formerly:
Performance measurement at only one measuring point in cooling and heating mode

Prior to 2013, air conditioning units were only rated by their EER and COP and heat pumps only by their COP. EER rated efficiency in cooling mode. COP defined efficiency in heating mode. The values were orientated towards a single operating point – less realistically and disadvantageously for consumers.

The performance data is only recorded at a single measuring point during full-load operation for the COP and EER.

Leistungsmessung bis 2013 - kühlen - EN
Leistungsmessung bis 2013 - heizen

With the ErP Directive:
Optimised performance measurement at four measuring points in cooling and heating mode

The performance data for SEER and/or SCOP is recorded at four different measuring points in line with DIN EN14825. The measuring points are weighted differently according to the temperature curves of the reference climate in Strasbourg, in order to reflect the energy efficiency of the unit under the most realistic conditions possible.

The following are also taken into consideration:

  • Thermostat-Off consumption
  • Standby consumption
  • Crankcase heating
Leistungsmessung seit 2013 - kühlen
Leistungsmessung seit 2013 - heizen

The SCOP value recorded is included in the calculation of the seasonal space heating energy efficiency (ηs) within Lot 1. Space heaters have to meet certain minimum requirements depending on the energy carrier used. The yardstick for heat pumps is significantly higher than for all other technologies. The energy efficiency of hot water heating (ηwh) is relevant for the energy efficiency classification in Lot 2.

For Lot 6 and Lot 21 (room air conditioning units and air/air heat pumps over 12 kW), the SEER and SCOP values are applied when calculating the annual performance ratios ηsc and ηsh.

ErP- Documentation

Manufacturers are required to provide corresponding ErP data sheets for all products on a public website.

The information featured on the data sheets varies depending on the lot in question. An example explanation of a data sheet for the heating and cooling operation of a room air conditioning unit is available here.
