BS EN 14037-5:2016EN 14037-5:2016 (E) 4 Introduction This European Standard results from the recognition, that heated and chilled ceiling radiant panels falling into the field of application hereinafter stated are traded on the basis of thei

22、r thermal output. For evaluating and comparing different heated and chilled ceiling surfaces it is therefore necessary to refer to a heating stipulated value. As installations with ceiling mounted radiant panels can also be used in practice for space cooling, it is nec-essary to have a test method f

23、or evaluating the cooling capacity. Installations with different free hanging heating and cooling surfaces need, for the use of space heating a test method for evaluating the heating out-put. The test method differs from the method for ceiling mounted radiant panels. BS EN 14037-5:2016EN 14037-5:201

24、6 (E) 5 1 Scope This European Standard describes the test method and the test installation for determining the thermal out-put of ceiling mounted heating surfaces according to the specifications 3.1, 3.2. and 3.3. This part applies to determine thermal output when chilled ceilings according to EN 14

25、240 are also used for heating. NOTE Test results according to this part cannot be compared with results according EN 140372 because great discrepancies are given at open ceilings, convective components and heating surfaces without upper insulation. 2 Normative references The following documents, in

36、ystem, which consists of a closed booth with controlled temperatures of the inside surfaces plus a set of two master panels built according to EN 14037-2:2016, Clause 6. Differing from the definitions of the test booth according to EN 14037-2:2016, the ceiling and the upper part of the vertical wall

37、s of the test booth shall be insulated until 0,5 m (0,02 m) below the ceiling with a specific thermal resistance of 2,5 (m K)/W. The method for measuring the thermal output consists of the measurement of mass flow and enthalpy dif-ference between inlet and outlet (by weighing method). Other measurem

38、ent methods shall guarantee in minimum the precision obtained by weighing method. The natural convection within the test booth shall not be affected by additional means. All laboratories that make tests according to this standard have to make comparable measurements with the other laboratories (acco
