FprEN ISO 11855-8

Building environment design - Design, dimensioning, installation and control of embedded radiant heating and cooling systems - Part 8: Electrical heating systems (ISO/FDIS 11855-8:2023)

This part of ISO 11855 specifies procedures and conditions to enable the heat flow in water based and electrical surface heating and cooling systems to be determined relative to the medium differential temperature for systems. The determination of thermal performance of water based surface heating and cooling systems and their conformity to this part of ISO 11855 is carried out by calculation in accordance with design documents and a model. This should enable a uniform assessment and calculation of water based surface heating and cooling systems.
The surface temperature and the temperature uniformity of the heated/cooled surface, nominal heat flow density between water or electrical heated layer and space, the associated nominal medium differential temperature, and the field of characteristic curves for the relationship between heat flow density and the determining variables are given as the result.
The ISO 11855 series is applicable to water based embedded surface heating and cooling systems in residential, commercial and industrial buildings. The methods apply to systems integrated into the wall, floor or ceiling construction without any open air gaps. It does not apply to ceiling mounted panel systems with open air gaps which are not integrated into the building structure.
The ISO 11855 series also applies, as appropriate, to the use of fluids other than water as a heating or cooling medium. The ISO 11855 series is not applicable for testing of systems. The methods do not apply to heated or chilled ceiling panels or beams.
Part 7 of the ISO 11855 series can also be used for electrical heated embedded systems.

Umweltgerechte Gebäudeplanung - Planung, Auslegung, Installation und Steuerung flächenintegrierter Strahlheizungs- und -kühlsysteme - Teil 8: Elektrische Heizsysteme (ISO/FDIS 11855-8:2023)

Dieses Dokument legt Verfahren und Bedingungen fest, welche die Bestimmung der Wärmestromdichte von elektrischen Flächenheizsystemen anhand der Temperaturdifferenz des Mediums für diese Systeme ermög
lichen. Die Bestimmung der thermischen Leistung von elektrischen Flächenheizsystemen und ihrer
stimmung mit diesem Dokument wird durch Berechnung nach den Planungsdokumenten und einem Modell vorgenommen. Dies ermöglicht eine einheitliche Bewertung und Berechnung von Flächenheizsystemen.
Als Ergebnis erhält man die Oberflächentemperatur, die Temperaturgleichmäßigkeit der beheizten Oberfläche sowie die Nenn-Wärmestromdichte zwischen der elektrisch beheizten Schicht und dem Raum.
Die NormenreiheISO11855 gilt für integrierte Flächenheiz- und -kühlsysteme mit Wasserdurchströmung in Wohn-, Gewerbe- und Industriegebäuden
1. Die Verfahren gelten für in Wände, Böden und Deckenkonstruktio
nen flächenintegrierte Systeme ohne offene Luftspalte. Sie gelten nicht für an der Decke montierte
teme mit offenen Luftspalten, die nicht in die Gebäudekonstruktion integriert sind.
Die NormenreiheISO11855 gilt gegebenenfalls auch für die Verwendung von anderen Flüssigkeiten als Wasser als Heiz- oder Kühlmedium. Die Prüfung von Systemen ist in der NormenreiheISO11855 nicht erfasst. Die beschriebenen Verfahren gelten nicht für beheizte oder gekühlte Deckenpaneele oder Träger und Balken.
