This document supersedes EN 14037-2:2003. This European Stan
21、dard 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of an identical text or by endorsement, at the latest by March 2017, and conflicting national standards shall be withdrawn at the latest by March 2017. Attention is drawn to the possibility that some of the elements of this
22、 document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. The main changes are: the title has been changed, the introduction has been changed, the scope has been changed, a new Master panel 2 has been added, Clause
23、9 “Test Report” has been reworked. 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 for space heating - Technical specifications and re-quirements;
24、 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; Part 4: Pre-fabricated ceiling mounted radiant panels for space
25、 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 countries are bound to implement this European Standard: Austria, Bel

BS EN 14037-2:2016EN 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 hereinafter stated are traded on the basis of their thermal output. F
28、or 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 for evaluating the c
29、ooling 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 14037-2:2016EN 14037-2:2016 (E) 6 1 Scope Thi
30、s 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 Normative references The following documents, in whole or in part, are normatively

33、SO/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 a closed booth with controlled temperatures of the inside surfaces plus a
34、 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 measurement methods shall guarantee in minimum the precision obtained by weighing
35、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 mounted radiant panels shall be constructed in a way that all six surroun
36、ding 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 1; Wall 3: the wall opposite of wall 1; Wall 4: the wall to the left of w

39、 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 infiltration. 5.5 Cooling system The cooling system is to be carried out in order,
40、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 shall not be higher than 0,5 K. That condition shall be maintained at the tests for the
41、 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 means of a globe thermometer (see Figure 2). The measuring point is situated on the v

47、ich are part of the testing system consist of a model with a full direct heating surface with a width of 1 190 mm (master panel 1) and of a model with 3 tubes and a radiant sheet as indirect heat-ing surface with a width of 300 mm. 6.2 General The purpose of the master panels is the following: a) to
48、 verify if the reproducibility of test values among test laboratories is within the limits set by this Euro-pean Standard; b) to establish a common basis for all test installations to verify that the repeatability of test values in each test installation is within the limits set by this European Sta
49、ndard. To verify the reproducibility among test installations built according to this standard a single set of master panels constructed and verified according to this standard will be circulated among test installations to de-termine the relevant M,sand O,svalues. This single set of master panels is named “primary set”. Each laboratory shall equip itself with the master panel 2 constructed and verified according to this stand-ard. This panel named “secondary set” shall be used to verify the repe
