8、in this document are as follows: ISO 7726 DIN EN ISO 7726 ISO 7730 DIN EN ISO 7730 ISO 13731 DIN EN ISO 13731 Amendments This standard differs from DIN EN 15377-1:2009-02 as follows: a) comfort conditions have been described in more detail; b) acoustical aspects of the heating system are now covered
9、; c) methods of determining the heating and cooling capacity are dealt with in DIN EN ISO 11855-2; d) the standard has been editorially revised. Compared with DIN EN ISO 11855-1:2015-11, the following corrections have been made: a) a national footnote has been included in Clause 3; b) in Subclause 3
10、.35, the letter symbol denoting the heating or cooling surface area has been corrected to read “AF” instead of “Af” (applies to the German version only); c) the term “maximale zulssige Oberflchentemperatur” given in Subclause 3.45 has been corrected to read “maximale Auslegungs-Wrmestromdichte”. In
11、addition, a national footnote on the underlying error in Subclause 2.45 of the original ISO document (where “maximum permissible surface temperature” is incorrectly stated instead of “maximum design heat flow density”) has been included; d) in Subclause 3.88, the letter symbol denoting the thermal o

DIN EN ISO 11855-1:2016-11 ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing Int
33、ernational 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 w
34、ith 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 technica
35、l 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

ISO 11855 consists of the following

38、ioning Part 4: Dimensioning and calculation of the dynamic heating and cooling capacity of Thermo Active Building Systems (TABS) Part 5: Installation Part 6: ControlPart 1 specifies the comfort criteria which should be considered in designing embedded radiant heating and cooling systems, since the m
39、ain 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 e
40、nsure 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 add
41、resses 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.

42、5 (E) DIN EN ISO 11855-1:2016-11 4IntroductionThe 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 sp
43、ace. 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 str
44、ucture, 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 co
45、mfort criteria for the space served by embedded systems, heat output calculation, dimensioning, dynamic analysis, installation, operation, and control method of embedded systems.EN ISO 11855-1:2015 (E) DIN EN ISO 11855-1:2016-11 5 1 ScopeThis part of ISO 11855 specifies the basic definitions, symbol
46、s, and a comfort criteria for radiant heating and cooling systems.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 w
47、ithout any open air gaps. It does not apply to 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 tes
48、ting of systems. The methods do not apply to heated or chilled ceiling panels or beams.2 Normative referencesISO 7726:1998, Ergonomics of the thermal environment Instruments for measuring physical quantitiesISO 7730:2005, Ergonomics of the thermal environment Analytical determination and interpretat
