Scope of the programme

This programme applies to standard chillers and hydronic heat pumps used for heating, air conditioning and refrigeration. They may operate with any type of compressor (hermetic, semi-hermetic and open) but only electrically driven chillers are included. Only refrigerants authorised in EU are considered. Units may be air-cooled or liquid cooled. Reverse cycle liquid chillers shall be certified in cooling and heating mode.

Heating-only hydronic heat pumps can be certified as an option.

The following units are specifically excluded from the certification programme:

  • chillers and heat pumps powered by other than electric motor drives
  • free cooling units
  • heat recovery mode
  • Total heat recovery mode
  • 4-pipes and 6-pipes chiller / heat-pumps
  • Evaporative cooled units

Note 1: Heat recovery units are included in the scope but the heat recovery function is not certified.

The programme covers all chillers and hydronic heat pumps with the limitation of cooling capacities of approved independent laboratories. The company participating in this certification programme shall certify all standard production models below the following cooling capacity at standard conditions (see Table 1).

Options:

For higher capacities

Air source units above 600 kW capacities can be certified as an option in Participant Laboratory.

Maximum capacities for air source units are defined for each participant according to the capacity of the participant’s laboratory and with a maximum at 1500 kW in cooling and heating mode (for the air conditioning application).

For heating-only hydronic heat pumps

Heating-only hydronic heat pumps can be certified as an option. If a participant applies to this option, all standard production models below the above mentioned maximum heating capacities at standard conditions have to be declared.

For 60 Hz units

As the “certify all” principle only applies to units intended for the European market (see definition of “Europe” in the Certification manual), it is not mandatory to declare 60 Hz units.

Moreover, these units can be certified by range.

Part Load Certification and ESEER calculation

Chillers usually operate at full load only during a limited period of time during a year.
Therefore the part load performance is much closer to reality and Eurovent decided to certify, together with full load efficiency, an average annual part load efficiency of chillers.

A study partly funded by the European Commission through SAVE Programme was performed and an index called ESEER – Seasonal energy efficiency ratio- has been defined.
This index similar to IPLV – Integrated part load value - used by ARI in the US, takes into account several parameters in order to establish an average use of chillers throughout Europe: weather data, building load characteristics, operational hours etc. Therefore the ESEER is realistic tool, much better than full load EER, to be used to compare average efficiency of two chillers. However it must be kept in mind that ESEER cannot be used to calculate exact energy consumption for a particular use in a particular geographic position.

In order to compute ESEER the three part load EER for 25%, 50% and 75% load are combined with full load EER. This global single figure is published in the Eurovent Directory of certified products together with cooling capacity and power input for standard conditions at full load. The operating temperatures and average weighting coefficients for Europe are given in the table below.

Method of calculation has been established for chillers not able to operate at fixed part load.

Operative ESEER temperatures and coefficients for air cooled and water cooled chillers in Europe:


ESEER parameters
Part Load Ratio
Air temperature (°C) Water temperature (°C) Weighting coefficients
100 3530 3 %
75 30 26 33 %
50 25 22 41 %
25 20 18 23 %

ESEER is calculated as follows:
ESEER = A.EER100% + B.EER75% + C.EER50% + D.EER25%
With the following weighting coefficients:
A = 0.03 ; B = 0.33 ; C = 0.41 ; D = 0.23

Energy efficiency classification

The purpose of Eurovent Energy Efficiency Classes is to simplify the selection of the best units for each type of Chillers. The classification is entirely voluntary, not related to any European Directive.

The energy efficiency of chillers is designated by “Eurovent Class A” or “Eurovent Class B” in catalogues and in the present Eurovent Directory of Certified products.

Based on existing chillers presented to Eurovent certification the following limits between classes are defined:
