33、 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

34、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 matter

35、s 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 circulat

36、ed 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

37、 for identifying any or all such patent rights. ISO 11855-4 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 h

38、eating 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)

39、 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-

40、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

41、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 heat

42、ing 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. DIN EN ISO 11855-4:2016-11EN ISO 11855-4:2015(E)4 Introduction The radiant heating and cooling system consists of heat emitting/absorbing, heat s

43、upply, 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 ser

44、ies 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 flu

45、ids 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, installatio

46、n, operation, and control method of embedded systems. DIN EN ISO 11855-4:2016-11EN ISO 11855-4:2015 (E) 5 1 Scope This part of ISO 11855 allows the calculation of peak cooling capacity of Thermo Active Building Systems (TABS), based on heat gains, such as solar gains, internal heat gains, and ventil

47、ation, and the calculation of the cooling power demand on the water side, to be used to size the cooling system, as regards the chiller size, fluid flow rate, etc. This part of ISO 11855 defines a detailed method aimed at the calculation of heating and cooling capacity in non-steady state conditions

48、. 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 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
