Water based surface embedded heating and cooling systems - Part 3: Dimensioning

Water based surface embedded heating and cooling systems - Part 3: Dimensioning

The EN 1264 series gives guidelines for surface embedded heating and cooling systems installed in buildings, residential and non-residential (e.g. office, public, commercial and industrial buildings) and focuses on systems installed for the purpose of thermal comfort.
The EN 1264 series gives guidelines for water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. It also specifies the use of other heating media instead of water, as appropriate.
The EN 1264 series specifies standardized product characteristics by calculation and testing the thermal output of heating for technical specifications and certification. For the design, construction and operation of these systems, see EN 1264-3 and EN 1264-4 for the types A, B, C, D, H, I and J. For the types E, F and G, see the EN ISO 11855 series.
The systems specified in the EN 1264 series are adjoined to the structural base of the enclosure surfaces of the building, mounted directly or with fixing supports. The EN 1264 series does not specify ceiling systems mounted in a suspended ceiling with a designed open air gap between the system and the building structure which allows the thermally induced circulation of the air. The thermal output of these systems can be determined according to EN 14037 series and EN 14240.
EN 1264-3 specifies the use in practical engineering of the results coming from EN 1264-2 and EN 1264-5.
For heating systems, physiological limitations are taken into account when specifying the surface temperatures. In the case of floor heating systems the limitations are realized by a design based on the characteristic curves and limit curves determined in accordance with EN 1264-2.
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

Die Normenreihe EN 1264 gibt Leitlinien für in Wohn- und anderen Gebäuden (z. B. Bürogebäuden, öffentlichen Gebäuden sowie Gewerbe- und Industriegebäuden) installierte raumflächenintegrierte Heiz- und Kühlsysteme und legt einen Schwerpunkt auf Systeme, die für den Zweck der thermischen Behaglichkeit installiert werden.
Die Normenreihe EN 1264 gibt Leitlinien für Heiz- und Kühlsysteme mit Wasserdurchströmung, die in die Raumum¬schließungsflächen des zu heizenden oder des zu kühlenden Raumes eingebettet sind. Sie legt ggf. auch die entsprechende Verwendung anderer Heizmittel als Wasser fest.
Die Normenreihe EN 1264 legt die Identifizierung standardisierter Produktmerkmale durch Berechnung und Prüfung der Wärmeleistung der Heizung für technische Spezifikationen und die Zertifizierung fest. Für das Design, den Bau und den Betrieb dieser Anlagen siehe EN 1264 3 und EN 1264 4 für die Typen A, B, C, D, H, I und J. Für die Typen E, F und G siehe Normenreihe EN ISO 11855.
Die in der Normenreihe EN 1264 festgelegten Systeme grenzen an den tragenden Untergrund der Umschließungsflächen des Gebäudes an und werden direkt oder mit Befestigungshalterungen angebracht. EN 1264 trifft keine Festlegungen für in abgehängten Decken montierte Deckensysteme mit einem auslegungsgemäßen offenen Luftspalt zwischen dem System und der Gebäudestruktur, der eine thermisch induzierte Umwälzung der Luft erlaubt. Die Wärmeleistung dieser Systeme kann nach der Normenreihe EN 14037 und EN 14240 bestimmt werden.
EN 1264 3 legt die Verwendung der Ergebnisse aus EN 1264 2 und EN 1264 5 im praktischen Ingenieur¬wesen fest.
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 EN 1264 2 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.

Water based surface embedded heating and cooling systems - Part 2: Floor heating: Methods for the determination of the thermal output using calculations and experimental tests
SIST EN 1264-2:2021

The EN 1264 series gives guidelines for surface embedded heating and cooling systems installed in buildings, residential and non-residential (e.g. office, public, commercial and industrial buildings) and focuses on systems installed for the purpose of thermal comfort.
The EN 1264 series gives guidelines for water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. It also specifies the use of other heating media instead of water, as appropriate.
The EN 1264 series specifies standardized product characteristics by calculation and testing the thermal output of heating for technical specifications and certification. For the design, construction and operation of these systems, see EN 1264-3 and EN 1264-4 for the types A, B, C, D, H, I and J. For the types E, F and G, see the EN ISO 11855 series.
The systems specified in the EN 1264 series are adjoined to the structural base of the enclosure surfaces of the building, mounted directly or with fixing supports. The EN 1264 series does not specify ceiling systems mounted in a suspended ceiling with a designed open air gap between the system and the building structure which allows the thermally induced circulation of the air. The thermal output of these systems can be determined according to the EN 14037 series and EN 14240.
EN 1264-2 specifies hot water floor heating systems. The application of EN 1264-5 requires the prior use of EN 1264-2. EN 1264-5 specifies the conversion of the thermal output of floor heating systems determined in EN 1264-2 into the thermal output of heating surfaces embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings.
EN 1264-2 specifies the boundary conditions and the test methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature.
The thermal output is tested by a calculation method and by a measurement method. The calculation method is applicable to systems corresponding to the definitions in EN 1264-1 (type A, B, C, D, H, I and J). The measurement method gives guidance for systems not corresponding to these definitions. The calculation method and the measurement method are consistent with each other and provide correlating and adequate test results.
The test results, expressed depending on further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference between the heating medium and the room.

This European Standard describes the test method and the test installation for determining the thermal output of ceiling mounted heating surfaces according to the specifications of prEN 14037-1:2011, 3.3.2, 3.3.3 and 3.3.4.
This part applies to determine thermal output when chilled ceilings according to EN 14240 are also used for heating.
NOTE   Test results according to this part cannot be compared with results according to EN 14037-2 because great discrepancies are given at open ceilings, convective components and heating surfaces without upper insulation.
