DIN EN 14037-3:2016-12 EN 14037-3:2016 (E) 4 Introduction This European Standard results from the

25、recognition, that heated and chilled ceiling radiant panels falling into the field of application 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

26、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 for evaluating the cooling capacity. Installations with different free hanging heating and cooling surfaces need, for the use of space heating a test met

27、hod for evaluating the heating out-put. The test method differs from the method for ceiling mounted radiant panels. DIN EN 14037-3:2016-12 EN 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

28、pre-fabricated ceiling mounted radiant panels. Pre-fabricated ceiling mounted radiant panels exchange 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 d

29、ifferent products, but these results un-derstate the output obtained under real operating conditions. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indis-pensable for its application. For dated references, only the edition ci

30、ted applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

31、nels for space heating - Test method for thermal output 3 Terms and definitions For the purposes 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

32、the active length The mean surface temperature shall be determined by an Infra-Red (IR) system with 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 sam

33、e test conditions described in EN 14037-2:2016, Clauses 5, 7 and 8. While testing the mean surface 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

34、shall be installed with the sensitive probe directed towards the central vertical axis of the ceil-ing mounted radiant panel (see Figure 1).

35、e length of the ceiling panel Figure 1 Arrangement of the IR system and the ceiling panel in the test 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 t

36、han 80 over the length and not less than 60 over the width of the panel. The tolerance of mean surface 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

37、The determination of the emissivity shall be carried out with samples of the original sheet covered with the surface coating used at production. The test shall be done by laboratories which comply with EN 14037-2:2016, Clause 4. DIN EN 14037-3:2016-12 EN 14037-3:2016 (E) 7 5 Thermal output conversio

38、n Determination of the rated thermal output Practical experiments under real conditions and simulation exercises 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

39、sizing of products a correction factor is applied to test data to give rated thermal output D. The factor of 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

40、temperature difference. 6 Evaluation of the thermal radiant output of a tested panel The radiant output of 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: = ra
