This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2017, and conflicting national standards shall be withdrawn at the latest by March 2017. Attenti

25、on is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

The European Standard EN 14037, Free hanging heating and cooling surfaces for water with a temperature below 120C, consists of the following parts: Part 1: Pre-fabricated ceiling mounted radiant panels

27、 for space heating - Technical specifications and re-quirements; Part 2: Pre-fabricated ceiling mounted radiant panels for space heating - Test method for thermal output; Part 3: Pre-fabricated ceiling mounted radiant panels for space heating - Rating method and evaluation of radiant thermal output;

28、 Part 4: Pre-fabricated ceiling mounted radiant panels for space heating - Test method for cooling capacity; Part 5: Open or closed heated ceiling surfaces - Test method for thermal output. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following count

29、ries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Pol

30、and, Portu-gal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 14037-2:2016-12 EN 14037-2:2016 (E) 5 Introduction This European Standard results from the recognition, that heated and chilled ceiling radiant panels falling into the field of application

31、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 space

32、 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 mounte

33、d radiant panels. DIN EN 14037-2:2016-12 EN 14037-2:2016 (E) 6 1 Scope This European Standard describes the test method and the test installation for determining the thermal out-put of pre-fabricated ceiling mounted radiant panels according to the specifications of EN 14037-1:2016, 3.3.1. 2 Normativ

36、requirements for the competence of testing and calibration laboratories (ISO/IEC 17025:2005) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 14037-1:2016 apply. 4 Testing of thermal output The test is carried out in a testing system, which consists of

37、 a closed booth with controlled temperatures of the inside surfaces plus a set of two master panels built according to Clause 6. 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. All laboratories that make tests according this standard have to make comparable measurements with the other laboratories (according to Clause 6 of this standard). 5 Test booth 5.1 General The booth for testing ceiling

39、 mounted radiant panels shall be constructed in a way that all six surrounding surfaces can be chilled. Figure 1 shows the schematic lay-out of a test booth with a six-wall cooling. The walls are defined as follows: Wall 1: the wall parallel to the inlet header; Wall 2: the wall to the right of wall

40、 1; Wall 3: the wall opposite of wall 1; Wall 4: the wall to the left of wall 1; DIN EN 14037-2:2016-12 EN 14037-2:2016 (E) 7 Wall 5: the floor; Wall 6: the ceiling.

42、 0,02) m. 5.3 Emissivity of the inside surrounding surfaces Walls, ceiling and floor shall have smooth inside surfaces covered with a coat of mat paint having a degree of emissivity of minimum 0,9. 5.4 Tightness of the test booth The test booth construction shall be sufficiently tight to prevent air

43、 infiltration. 5.5 Cooling system The cooling system is to be carried out in order, that the difference between the 6 chilled surrounding inside surfaces of the test booth and the average temperature of all 6 surfaces is not higher than 0,5 K. The temper-ature difference between inlet and outlet sha

44、ll not be higher than 0,5 K. That condition shall be maintained at the tests for the determination of the characteristic equation. 5.6 Temperature measuring points 5.6.1 Reference room temperature The reference room temperature is measured at a height of 0,75 m above the floor of the test booth by m

45、eans of a globe thermometer (see Figure 2). The measuring point is situated on the vertical axis through the central point of the ceiling mounted radiant panel.
