Water based surface embedded heating and cooling systems - Part 5: Determination of the thermal output for wall and ceiling heating and for floor, wall and ceiling cooling

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 1264-5 specifies the recalculation of values determined in EN 1264-2 for the system in question. It enables the conversion of the calculation and measurement results of EN 1264-2 into results for other surface orientations in the room, i.e. for ceiling and wall heating, as well as for the application as cooling surfaces, i.e. for floor, ceiling and wall cooling. The test results of EN 1264-2 are the basis of all calculation, whether or not the system in question is used for heating or cooling application.

Raumflächenintegrierte Heiz- und Kühlsysteme mit Wasserdurchströmung - Teil 5: Bestimmung der Wärmeleistung von Wand- und Deckenheizung sowie Kühlleistung von Fußboden-, Wand- und Deckenkühlung

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 Raumumschließungsflächen 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. Die Normenreihe 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 5 legt die Umrechnung von Werten fest, die in EN 1264 2 für das betreffende System bestimmt wurden. Sie ermöglicht die Umrechnung der Berechnungs- und Messergebnisse von EN 1264 2 in Ergebnisse für andere Oberflächenausrichtungen im Raum, d. h. für die Wand- und Deckenheizung, sowie für die Anwendung als Kühlflächen, d. h. für die Fußboden , Decken- und Wandkühlung. Daher sind die Prüfergebnisse von EN 1264 2 die Basis aller Berechnungen, unabhängig davon, ob das betreffende System für Heiz- oder für Kühlanwendungen eingesetzt wird.

Systèmes de surfaces chauffantes et rafraîchissantes hydrauliques intégrées - Partie 5 : Détermination de l'émission thermique des surfaces chauffantes et rafraîchissantes intégrées dans les sols, les plafonds et les murs

La série EN 1264 fournit des lignes directrices pour les systèmes de surfaces chauffantes et rafraîchissantes intégrées dans les bâtiments résidentiels et non résidentiels (par exemple, des bureaux, des bâtiments publics, commerciaux et industriels), et se concentre sur les systèmes installés à des fins de confort thermique.
La série EN 1264 fournit des lignes directrices pour les systèmes de surfaces chauffantes et rafraîchissantes intégrées dans les parois des pièces à chauffer ou à rafraîchir. Elle spécifie également l'utilisation de fluides caloporteurs autres que l'eau, le cas échéant.
La série EN 1264 spécifie les caractéristiques normalisées des produits en calculant et en mettant à l'essai l'émission thermique du chauffage pour les spécifications techniques et la certification. Pour la conception, la construction et le fonctionnement de ces systèmes, voir l'EN 1264-3 et l'EN 1264-4 pour les types A, B, C, D, H, I et J. Pour les types E, F et G, voir la série EN ISO 11855.
Les systèmes spécifiés dans la série EN 1264 sont fixés directement ou à l'aide de supports de fixation au plancher porteur des parois du bâtiment. La série EN 1264 ne spécifie pas les systèmes de plafond montés dans un plafond suspendu, dont l'entrefer ouvert conçu entre le système et la structure du bâtiment permet la circulation de l'air induite par la chaleur. L'émission thermique de ces systèmes peut être déterminée selon la série EN 14037 et l'EN 14240.
L'EN 1264-5 spécifie le recalcul des valeurs déterminées dans l'EN 1264-2 pour le système en question. Il permet de convertir les résultats de calcul et de mesure de l'EN 1264-2 en résultats pour des surfaces orientées différemment, telles que les plafonds et les murs chauffants, ainsi que pour les applications de surfaces rafraîchissantes, telles que les systèmes rafraîchissants par le sol, les plafonds ou les murs. Les résultats d'essais de l'EN 1264-2constituent la base de tous les calculs, que le système en question soit utilisé ou non pour des applications de chauffage ou de refroidissement.

Introduction

The EN 1264 series is based on the realization that in the field of commercial trade the thermal output

of heating and cooling systems represents the basis of rating. In order to be able to evaluate and

compare different heating and cooling systems, it is therefore necessary to refer to values determined

using one single, unambiguously defined method. The basis for doing so are the test methods for the

determination of the thermal output of floor heating systems specified in EN 1264-2. In analogy to

EN 442-2, Radiators and convectors — Part 2: Test methods and rating, this test method provides

characteristic partial load curves under defined boundary conditions as well as the characteristic

output of the system represented by the standard thermal output together with the associated standard

temperature difference between the heating medium and the room temperature.

1 Scope

EN 1264 covers 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.

EN 1264 applies to water based heating and cooling systems embedded into the enclosure surfaces of the

room to be heated or to be cooled. It also applies as appropriate to the use of other heating media instead

of water.

EN 1264 applies to identify 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, EN ISO 11855 applies.

The systems covered in EN 1264 are adjoined to the structural base of the enclosure surfaces of the

building, mounted directly or with fixing supports. It does not cover 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 ISO 18566, EN 14037 and EN 14240.

EN 1264-5 deals with the recalculation of values determined in EN 1264-2 for the system in question. It

enables the conversion of the calculation and measurement results of EN 1264-2 into results for other

surface orientations in the room, i.e. for ceiling and wall heating, as well as for the application as cooling

surfaces, i.e. for floor, ceiling and wall cooling. The test results of EN 1264-2 are the basis of all calculation,

whether or not the system in question is used for heating or cooling application.
