Translation of "Couche d'absorption de chaleur " (French → English) :

The lower part of the atmosphere (tropospheric layer) contains an important beneficial concentration of carbon dioxide that holds the sun heat (however a higher concentration of the CO2 causes an enhanced greenhouse effect with climate change as a possible result).

The product group ‘electrically driven, gas driven or gas absorption heat pumps’ shall comprise heat pumps, which can concentrate energy present in the air, ground or water into useful heat for the supply of space heating or the opposite process for space cooling.

In order to be awarded the Community eco-label under Regulation (EC) No 1980/2000, a heat pump must fall within the product group ‘electrically driven, gas driven or gas absorption heat pumps’ and must comply with each of the criteria set out in the Annex to this Decision.

The primary energy ratio (PER) is given by: COP × 0,40 (or COP/2,5) for electrically driven heat pumps and by COP × 0,91 (or COP/1,1) for gas driven or gas absorption heat pumps, where 0,40 is the current European average electricity power generation efficiency including grid losses and 0,91 is the current European average gas efficiency including distribution losses according to Directive 2006/32/EC of the European Parliament and of the Council of 5 April 2006 on energy end-use efficiency and energy services and repealing Council Directive 93/76/EEC

7 ". Surfactant" means any organic substance and/or preparation used in detergents which has surface-active properties, and which consists of one or more hydrophilic and one or more hydrophobic groups of such a nature and size that it is capable of reducing the surface tension of water , forming spreading or adsorption monolayers at the water-air interface, forming emulsions and/or microemulsions, forming micelles and adsorption at water-solid interfaces ;

6. “Surfactant” means any organic substance and/or preparation used in detergents which is intentionally added to achieve cleaning, rinsing, fabric softening and/or any other purpose due to its surface-active properties, and which consists of one or more hydrophilic and one or more hydrophobic groups of such a nature and size that it is capable of reducing the surface tension of water, forming spreading or adsorption monolayers at the water-air interface and forming emulsions and/or microemulsions and micelles, and of adsorption at wa ...[+++]ter-solid interfaces;
