BS EN 14037-3:2016EN 14037-3:2016 (E) 4 Introduction This European Standard results from the recognition, that heated and chilled ceiling radiant panels falling into the field of applic

22、ation hereinafter stated are traded on the basis of their 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

23、 space cooling, it is nec-essary to have a test method for 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

24、mounted radiant panels. BS EN 14037-3:2016EN 14037-3:2016 (E) 5 1 Scope This European Standard describes the procedure to determine the rated thermal output (D) and the mean surface temperature (trp) of pre-fabricated ceiling mounted radiant panels. Pre-fabricated ceiling mounted radiant panels exch

25、ange heat mainly by radiation. The test methods for determining the thermal output of pre-fabricated ceiling mounted radiant panels, as described in EN 14037-2:2016, give reliable results for comparing different products, but these results un-derstate the output obtained under real operating conditi

28、of this document, the terms and definitions given in EN 14037-1:2016 apply. 4 Testing of the mean surface temperature and the emissivity of the panel 4.1 Determination of the mean surface temperature of the active length The mean surface temperature shall be determined by an Infra-Red (IR) system wi

29、th the following features: automatic mean temperature of the measured surface including the emissivity, the distance and the ambient temperature. The test is made in the same test booth and under the same test conditions described in EN 14037-2:2016, Clauses 5, 7 and 8. While testing the mean surfac

30、e temperature, the connecting components shall be insulat-ed. The mean surface temperature shall be determined with the IR system for each testing point according to EN 14037-2:2016, 8.10. The IR system shall be installed with the sensitive probe directed towards the central vertical axis of the cei

32、booth during determination with only one testing point The distance between the surface of the ceiling mounted radiant panel and the sensor shall be two meters. The field of view shall be not less than 80 over the length and not less than 60 over the width of the panel. The tolerance of mean surface

33、 temperature shall be not more than 1,0 K. The results of the determination of the radiant output shall be reported in accordance with EN 14037-2:2016, Clause 9. 4.2 Determination of the emissivity The determination of the emissivity shall be carried out with samples of the original sheet covered wi

34、th the surface coating used at production. The test shall be done by laboratories which comply with EN 14037-2:2016, Clause 4. BS EN 14037-3:2016EN 14037-3:2016 (E) 7 5 Thermal output conversion Determination of the rated thermal output Practical experiments under real conditions and simulation exer

35、cises indicate that test booth results under-state output from radiant ceiling mounted panels by a factor of about 10 %. In order to ensure that designers are able to use test data for correct sizing of products a correction factor is applied to test data to give rated thermal output D. The factor o

36、f 1,1 shall be introduced in the characteristic equation determined according to EN 14037-2:2016, 8.13. The rated thermal output shall be taken from this equation in correspondence of standard temperature difference. 6 Evaluation of the thermal radiant output of a tested panel The radiant output of

37、the tested panel can be calculated for each measuring point as follows: = 44rad rp rp w rp()TTA The referred percentage of radiant output is calculated for each measuring point as follows: = radact100r BS EN 14037-3:2016EN 14037-3:2016 (E) 8 Bibliography 1 EN ISO/IEC 17025, General requirements for
