DIN EN 1264-2:2013-03EN 1264-2:2008+A1:2012 (E) 4 Introduction This European Standard is based on the realisation that in the field of commercial trade, the t
28、hermal output of heating and cooling systems represents the basis of rating. In order to be able to evaluate and compare different heating and/or cooling systems, it is, therefore, necessary to refer to values determined using one single, unambiguously defined method. The basis for doing so are the
29、prove methods for the determination of the thermal output of floor heating systems specified in Part 2 of this European Standard. In analogy to the European Standard EN 442-2 (Radiators and convectors Part 2: Test methods and rating), these prove methods provide characteristic partial load curves un
30、der 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. DIN EN 1264-2:2013-03EN 1264-2:2008+A1:2012 (E) 5 1 Scope Th
31、is European Standard specifies the boundary conditions and the prove methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature. This standard shall be applied to commercial tr
32、ade and practical engineering if proved and certifiable values of the thermal output shall be used. This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This Part of this European Standard applies to hot water fl
33、oor heating systems. Applying of Part 5 of this European Standard requires the prior use of this Part of this European Standard. Part 5 of this European Standard deals with the conversion of the thermal output of floor heating systems determined in Part 2 into the thermal output of heating surfaces
34、embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings. The thermal output is proved by a calculation method (Clause 6) and by a test method (Clause 9). The calculation method is applicable to systems corresponding to the definiti
35、ons in EN 1264-1 (type A, type B, type C, type D). For systems not corresponding to these definitions, the test method shall be used. The calculation method and the test method are consistent with each other and provide correlating and adequate prove results. The prove results, expressed depending o
36、n further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference
37、 between the heating medium and the room. 2 Normative references !The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of t
38、he referenced document (including any amendments) applies.

39、s of this document, the terms and definitions given in !EN 1264-1:2011“ apply. 4 Thermal boundary conditions A floor heating surface with a given average surface temperature exchanges the same thermal output in any room with the same indoor room temperature (standard indoor room temperature i). It i
40、s, therefore, possible to give a basic characteristic curve of the relationship between specific thermal output and average surface temperature that is independent of the heating system and applicable to all floor heating surfaces (including those having peripheral areas with greater heat emissions)
41、 (see Figure A.1). In contrast, every floor heating system has its own maximum permissible specific thermal output, the limit specific thermal output, qG. This output is calculated for an ambient (standard) indoor room temperature DIN EN 1264-2:2013-03EN 1264-2:2008+A1:2012 (E) 6 i= 20 C. The other
42、condition is the maximum surface temperature F, max= 29 C1)at temperature drop between supply and return of the heating medium = 0 K. The maximum specific thermal output for the peripheral area will be achieved at a maximum surface temperature F, max= 35 C2)and = 0 K. For the calculation and for the
43、 test procedure, the centre of the heating surface is used as the reference point for F, max, regardless of system type. The average surface temperature F, m, determining the specific thermal output (see basic characteristic curve) is linked with the maximum surface temperature. In this context, F,
44、m4 000 kg/(h m). There is no lateral heat flow. The heat-conducting layer of the floor heating system is thermally decoupled by thermal insulation from the structural base of the building. NOTE The aforementioned last condition does not concern the test procedure of Clause 9. 5 Documents for testing
45、 The system suppliers documents are taken as the basis for the determination of the thermal output. The following documents shall be provided: Installation drawing (section) of the floor heating system, covering two pipe spacing, including the peripheral area and giving information on the materials
46、used (if necessary, the test results regarding the heat conductivity values of the materials shall be provided). Technical documentation of the system. This information shall contain any details necessary for the calculation of the construction customary on site. It shall be submitted to the install
47、er in the same form. With a member of the testing body present, a demonstration surface of approximately 2 m 2 m is constructed to represent the actual construction used on site. 1) National regulations may limit this temperature to a lower value. 2) Some floor covering materials may require lower t
