ABOUT THE INTERPRETATION OF ECODESIGN REGULATION (EU) 2016/2281 

After the consultations done with TC 113/WG 7, who is in charge of EN 14825 standard, it has been clarified that F(2) factor is only applied to the calculation of 'seasonal space cooling efficiency’ (ηs,c) of the ground coupled water-to-water and brine-to-water units. Correspondingly, all ηs,c values of concerned units have been corrected in the ‘Certified Product Directory’. The further information related to this modification can be found in the article of Eurovent Association, titled as “Eurovent 6/17 - 2020: Ecodesign Regulation (EU) 2016/2281”. 

Scope of the programme

The Eurovent Certified Performance (ECP) programme scope for Chillers & Heat Pumps (LCP-HP) covers the standard air and water (brine) source chillers and hydronic heat pumps used for heating, air conditioning and refrigeration applications, which are equipped with any type of electrically-driven compressor. The intended use of the certified models can be residential, commercial, or industrial. 

For the full programme scope and exclusions please view the Technical Certification Rules.

Certify-all principle

For the LCP-HP programme, the certify-all rule applies as defined in the Certification Manual in force and in the Technical Certification Rules. Whenever a company participates in the LCP-HP programme, all liquid chilling packages and hydronic heat pumps (packaged or split), which are promoted by the applicant/participant to the endusers, specifiers, trading companies, and the contractors in the European market, (as defined in the Certification Manual in force), by means of paper or electronic catalogue, price list or in a selection tool
within the scope of the programme shall be certified. This shall be done in accordance with the Technical Certification Rules (TCR) and includes all the models in modular ranges. 

Notes on certification:

  • The capacity limits of the certified units can be found in table 1 of the TCR.
  • The scope of the Certify-all Principle of the LCP-HP Programme can be found in table 2 of the TCR.
  • Other unit types and units with higher capacities than the limits given in the TCR can be certified as an option. 
  • Market-specific certification for India and/or Middle East is also available as an option for participants. 

Product type

Chillers and heat pumps in the LCP-HP programme can used for heating, air conditioning and refrigeration, in buildings and processes. Units can be used in a wide range of residential, commercial, or industrial applications. The definitions for the product types covered by this program are as follows. 

Comfort Chiller: A unit designed to either cool, or cool and heat, liquid using an evaporator, a condenser, a refrigerant compressor, and appropriate controls. Leaving chilled water temperatures for cooling mode are greater than or equal to + 2 °C. Also known as a liquid chilling package. 

Heat pump: A unit designed to only heat liquid, using an evaporator, a condenser, a refrigerant compressor, and appropriate controls. Also known as a hydronic heat pump. 

2+2-pipe Multipurpose chiller: A chiller designed to cool and heat the liquid simultaneously with two different water loops. For its cooling-only and heating-only function, the same water loop can be used. The second water loop is generally used for domestic hot water during heating-only or during the simultaneous cooling and heating function. 

4-pipe Multipurpose chiller: A chiller designed to cool and heat the liquid simultaneously with two different water loops. For its cooling-only and heating-only function, the same water loop cannot be used. 

Process chiller: A chiller capable of cooling down and continuously maintaining the temperature of a liquid in order to provide cooling to a refrigerated appliance, or to a process cooling system. 

The heat source options of the units are as follows.  

Air-cooled or air to water: Means that heat is taken from the outside air and transferred to the indoor water-based system during the unit’s heating function. For cooling function, the unit extracts the heat from the indoor water-based system and transfers it to the outside air. 

Water-cooled or water to water: Means that heat is taken from the outdoor water loop and transferred to the indoor water-based system during the unit’s heating function. For cooling function, the unit extracts the heat from the indoor water-based system and transfers it to the outdoor water, which might be sent to a cooling tower/water loop system or a ground loop. 

Unit structure is split in two different categories: 

  • Packaged: Factory assembly of components of refrigeration system, fixed on a common mounting to form a discrete unit. 
  • Split: Factory assembly of components of refrigeration system, fixed on two mountings to form a discrete matched functional unit.

With the combinations of the main characteristics above, product types are defined. 

Definitions

While exploring our certified products you’ll come across a number of technical terms relating to certification. The below definitions help explain the search criteria in our certified product directory.

You should note that due to the large number of certified product types in the LCP-HP programme, performance can be certified against differing criteria and conditions. The conditions of certified performances are provided by using the initials of the heat sources (A-air and W-water) and by giving first the outdoor side and then the indoor side. Such as:

A35/W12-7 = Outdoor side air temperature 35 °C / Indoor side water inlet 12 °C and water outlet 7 °C.

W30-35/Wm19-m25 = Outdoor side water inlet 30 °C and water outlet 35 °C / Indoor side water inlet -19 °C and water outlet -25 °C.

If a unit has an integrated water pump, then available (serviceable) pressure performance filter should be used.
