Building environment design - Design, dimensioning, installation and control of embedded radiant heating and cooling systems - Part 3: Design and dimensioning (ISO 11855-3:2012)

This European Standard shall stipulate the processes and conditions needed to design radiant heating and cooling systems embedded in the structures of the rooms. In addition, this standard includes the determination of heating and cooling capacity, dimensioning, dynamic analysis, installation, commissioning, operation, and control methods of radiant heating and cooling system. This international standard is applicable to embedded system that is integrated with the building structure. But this is not applicable to the panel system with open air gap, which is not integrated with the building structure. This standard applies also, as appropriate, to the use of other fluids or electricity instead of water as heating or cooling medium.
Part 3 of this standard deals with system design and dimensioning method to ensure the heating and cooling capacity of the radiant heating and cooling systems.

Conception de l'environnement des bâtiments - Normes pour la conception, la construction et le fonctionnement des systèmes de chauffage et de refroidissement par rayonnement - Partie 3: Conception et dimensionnement (ISO 11855-3:2012)

ISO 11855-3:2012 définit une méthode de conception et de dimensionnement de systèmes permettant de garantir la puissance calorifique et frigorifique des systèmes de chauffage et de refroidissement par rayonnement.
La série ISO 11855 s'applique aux systèmes de chauffage et de refroidissement de surface intégrés à eau dans les bâtiments résidentiels, commerciaux et industriels. Ces méthodes s'appliquent aux systèmes intégrés dans les murs, sols ou plafonds, sans ouverture à l'air libre. Elles ne s'appliquent pas aux systèmes de panneaux avec ouvertures à l'air libre, qui ne sont pas intégrés dans une structure de bâtiment.
La série ISO 11855 s'applique également, le cas échéant, à l'utilisation d'autres fluides que l'eau en tant que medium de chauffage ou de refroidissement. La série ISO 11855 ne s'applique pas à l'essai des systèmes. Ces méthodes ne s'appliquent pas aux panneaux ou poutres de plafond chauffés ou refroidis.

Načrtovanje gradnje - Načrtovanje, dimenzioniranje, montaža in kontrola vgrajenih hladilnih in ogrevalnih sistemov - 3. del: Načrtovanje in dimenzioniranje (ISO 111855-3:2012)

Ta evropski standard določa procese in pogoje, potrebne za načrtovanje ogrevalnih in hladilnih sistemov, vgrajenih v strukture sobe. Poleg tega ta standard zajema določanje grelne in hladilne moči, dimenzioniranje, dinamično analizo, montažo, zagon, delovanje in kontrolne metode ogrevalnih in hladilnih sistemov. Ta mednarodni standard se uporablja za vgrajeni sistem, ki je vključen v strukturo stavbe. Vendar se ne uporablja za sistem plošč z odprtim vmesnim zračnim prostorom, ki ni vključen v strukturo stavbe. Ta standard, kadar je to ustrezno, velja tudi za uporabo drugih tekočin ali električne energije namesto vode za ogrevalni ali hladilni medij. 3. del tega standarda obravnava načrtovanje sistema in metodo za dimenzioniranje za zagotavljanje grelne in hladilne moči ogrevalnih in hladilnih sistemov.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11855-3 was prepared by Technical Committee ISO/TC 205, Building environment design.
ISO 11855 consists of the following parts, under the general title Building environment design — Design,
dimensioning, installation and control of embedded radiant heating and cooling systems:
— Part 1: Definition, symbols, and comfort criteria
— Part 2: Determination of the design and heating and cooling capacity
— Part 3: Design and dimensioning
— Part 4: Dimensioning and calculation of the dynamic heating and cooling capacity of Thermo Active
Building Systems (TABS)
— Part 5: Installation
— Part 6: Control
Part 1 specifies the comfort criteria which should be considered in designing embedded radiant heating
and cooling systems, since the main objective of the radiant heating and cooling system is to satisfy
thermal comfort of the occupants. Part 2 provides steady-state calculation methods for determination of
the heating and cooling capacity. Part 3 specifies design and dimensioning methods of radiant heating and
cooling systems to ensure the heating and cooling capacity. Part 4 provides a dimensioning and calculation
method to design Thermo Active Building Systems (TABS) for energy saving purposes, since radiant
heating and cooling systems can reduce energy consumption and heat source size by using renewable
energy. Part 5 addresses the installation process for the system to operate as intended. Part 6 shows a
proper control method of the radiant heating and cooling systems to ensure the maximum performance
which was intended in the design stage when the system is actually being operated in a building.

ISO 11855-3:2012(E)
Introduction
The radiant heating and cooling system consists of heat emitting/absorbing, heat supply, distribution,
and control systems. The ISO 11855 series deals with the embedded surface heating and cooling system
that directly controls heat exchange within the space. It does not include the system equipment itself,
such as heat source, distribution system and controller.
The ISO 11855 series addresses an embedded system that is integrated with the building structure.
Therefore, the panel system with open air gap, which is not integrated with the building structure, is
not covered by this series.
The ISO 11855 series shall be applied to systems using not only water but also other fluids or electricity
as a heating or cooling medium.
The object of the ISO 11855 series is to provide criteria to effectively design embedded systems. To do
this, it presents comfort criteria for the space served by embedded systems, heat output calculation,
dimensioning, dynamic analysis, installation, operation, and control method of embedded systems.
