Water based surface embedded heating and cooling systems - Part 3: Dimensioning
This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled.
This document deals with the use in practical engineering of the results coming from part 2 and 5 and is applicable to floor-, ceiling- and wall heating systems, as well floor-, ceiling- and wall cooling systems.
For heating systems, physiological limitations are taken into account when specifying the surface temperatures. In the case of floor heating systems the limitations are realised by a design based on the characteristic curves and limit curves determined in accordance with part 2 of this Standard.
For cooling systems, only a limitation with respect to the dew point is taken into account. In predominating practice, this means that physiological limitations are included as well.
Raumflächenintegrierte Heiz- und Kühlsysteme mit Wasserdurchströmung - Teil 3: Auslegung
Diese Europäische Norm gilt für raumflächenintegrierte Heiz- und Kühlsysteme, welche in die Raumumschließungsflächen
des zu heizenden oder des zu kühlenden Raumes integriert sind.
Dieses Dokument behandelt die Anwendung der Ergebnisse aus den Teilen 2 und 5 im praktischen
Ingenieurswesen und gilt sowohl für Fußboden-, Decken- und Wandheizsysteme als auch für Fußboden-,
Decken- und Wandkühlsysteme.
Im Falle von Heizsystemen werden die physiologisch bedingten Grenzen bei der Festlegung der Oberflächentemperaturen
berücksichtigt. Im Falle von Fußbodenheizsystemen wird den Grenzen durch eine Auslegung
Rechnung getragen, die auf den nach Teil 2 dieser Norm ermittelten Kennlinien und Grenzkurven basiert.
Im Falle von Kühlsystemen wird eine Leistungsbegrenzung ausschließlich durch den Taupunkt berücksichtigt.
In der Praxis bedeutet dies in der Regel, dass dadurch zugleich die physiologisch bedingten Grenzen
einbezogen werden.
Systèmes de surfaces chauffantes et rafraîchissantes hydrauliques intégrées - Partie 3 : Dimensionnement
La présente Norme européenne s'applique aux systèmes de surfaces chauffantes et rafraîchissantes
intégrées dans le sol, les plafonds et les murs d'une pièce devant être chauffée ou rafraîchie.
Le présent document traite de l'utilisation, dans l'ingénierie pratique, des résultats émanant des parties 2 et 5
et s’applique aux systèmes de chauffage par le sol, les plafonds et les murs, ainsi qu’aux systèmes de
rafraîchissement dans les sols, les plafonds et les murs.
Pour les systèmes de chauffage, les limites physiologiques sont prises en compte lors de la définition des
températures de surface. Dans le cas de systèmes de chauffage par le sol, les limites sont calculées à l'aide
de courbes caractéristiques et de courbes limites déterminées conformément à la partie 2 de la présente
Norme européenne.
Pour les systèmes de rafraîchissement, seule une limite par rapport au point de rosée est prise en compte.
Dans la majorité des cas, cela signifie que les limites physiologiques sont également comprises.

For heating systems, physiological limitations are taken into account when specifying the surface temperatures. In the case of floor heating systems the limitations are realised by a design based on the characteristic curves and limit curves determined in accordance with part 2 of this Standard. For cooling systems, only a limitation with respect to the dew point is taken into account.

(1) 4.1.1.2 Characteristic curve The characteristic curve describes the relationship between the specific thermal output q of a system and the required temperature difference between heating water and room ∆ϑH. For a simplification, the specific thermal output is taken directly proportional to the temperature difference:
q = KH ⋅ ∆ϑH (2) where the gradient is KH = B )(iimia, calculated in accordance with clause 6 of part 2 of this Standard, or the gradient KH is experimentally determined in accordance with clause 9 of part 2 of this European Standard. 4.1.1.3 Field of characteristic curves The field of characteristic curves of a floor heating system with a specific pipe spacing T shall at least contain the characteristic curves for values of the thermal resistance Rλ, B = 0, Rλ, B = 0,05, Rλ, B = 0,10 and Rλ, B = 0,15 (m2 K)/W in accordance with part 2 of this European Standard (see Figure A.1). Values of Rλ, B > 0,15 (m2 K)/W shall not be used if possible. 4.1.1.4 Limit curves The limit curves in the field of characteristic curves describe in accordance with part 2 of this European Standard the relationship between the specific thermal output q and the temperature difference ∆ϑH between the heating water and the room in the case where the physiologically agreed limit values of surface temperatures ϑF,max = 29 °C (occupied area) or ϑF,max = 35 °C (peripheral area) are reached1. For bathrooms (ϑi = 24 °C) the limit curve for (ϑF,max - ϑi) = 9 K also applies. For design purposes, i.e. the determination of design values of the specific thermal output and the associated temperature difference between heating water and room, the limit curves are valid for the temperature drop σ of the heating water in a range of 0 K < σ ≤ 5 K. The limit curves are used to specify the maximum permissible flow temperature (refer to clause 4.1.3.2 and Figure A.4).
