25、ally, also heat the incoming air (outside air) Note 1 to entry: In this context, the air is led directly to the radiator and, once heated by the radiator, fed to the room. The controlled air feed is performed mechanically, either using a fan in the primary air system or through an exhaust air system

28、ors The back wall of the test room shall be cooled to a surface temperature of 16 C 0,5 K during the test (see Figure 1). This can be done either by the back wall itself or by a flat cooling surface (emission coefficient has to be at least 0,9) covering the whole width and height of the room placed
29、in front of the back wall of the closed test room in accordance with EN 442-2. The space between the cooling plate and the booth back wall shall be closed off to prevent air from flowing through.

30、1 Positioning of the cooling surface in the test room The trench convector with its associated trench and the intended covering is installed in the booth floor in front of this cooling surface, flush with the finished floor level, in accordance with the manufacturers instructions. Unless other dimen
31、sions have been given by the manufacturer, the distance between the trench and the cooled back wall shall be 0,05 m (see Figure 2). For the purposes of the test, the trench in itself is covered with a thermal insulation shown in Figure 2 which has a thermal resistance of at least R =1,0 m2K/W. If th
32、e floor of the test booth is cooled then the floor has to have a thermal resistance of at least R =2,5 m2K/W. If the floor of the test booth is not cooled then there is no requirement for such a thermal resistance. BS EN 16430-2:2014EN 16430-2:2014 (E) 6 Dimensions in millimetres Key h height c dept

In the case of trench convectors without fan(s) the convec
35、tor length to be tested (finned length) should be 2 m; if that length is not available, the next available length 2 m shall be tested. The length of the sample under test shall be adapted if the requirements for either the minimum or maximum thermal output according to 4.2.1 are not fulfilled. In th
36、e case of finned tube convectors, a finned length of 1 m is assumed as the module. In the case of trench convectors with fan(s) the convector length to be tested (finned length) should be at least 1 m, if that length is not available, the next available length 1 m shall be tested. The length of the
37、sample under test shall be adapted if the requirements for either the minimum or maximum thermal output according to 4.2.1 are not fulfilled. The convector as such is installed in the trench, applying the manufacturers fixing material, spacers, covering, etc. and following the manufacturers instruct

The testing application shall be accompanied by drawings showing the dimensions of the trench and the convector as well as the convectors positioning in the trench and the design of the covering. 4.1.2 Fan assisted radiators and wall mounted convectors Radiators and wall mounted convectors sha

Unless other dimensions have been given by the manufacturer, the distance between the radiator / convector and the back wall of the test room shall be 0,05 m, the distance between the radiator / convector and the floor of the test room shall be 0,11 m. If it is
40、 possible to allocate the models to a certain type with a characteristic size (e. g. height) whose changes point to the fact that a continuous dependence of the thermal output can be expected, the smallest and the largest sizes each and so many intermediate sizes shall be tested that a ratio of 1:2
41、is not exceeded. In the case of radiators / convectors the length of the sample to be tested (in case of convectors: finned length) should be 1 m, if that length is not available, the next available length 1 m shall be tested. The length BS EN 16430-2:2014EN 16430-2:2014 (E) 7 of the sample under te
42、st shall be adapted if the requirements for either the minimum or maximum thermal output according to 4.2.1 are not fulfilled.

The testing application shall be accompanied by drawings showing the dimensions of the trench and the convector as well as the radiators / convectors positioning in the test room and the design of the covering. 4.2 Test procedure 4.2.1 Scope of testing The selection of the samples and the scop
44、e of testing shall be to specifications analogous to EN 442-2. The standard heating output is to be determined at different water flow rates with the following limitations: Thermal output: min. 200 W; max. 3 500 W (according at standard conditions). 4.2.2 Determination of the thermal output 4.2.2.1
45、General The procedure of the test and the determination of the thermal output are performed in accordance with EN 442-2. EN 442-2, applies analogously with regard to the requirements for measuring instruments. Here, a characteristic formula: = Km Tn(1) Where: is the thermal output Kmis the constant
46、of the model T is the excess temperature n is the exponent shall be determined on the basis of at least three measuring points, at a constant water flow rate and excess temperatures of T = (60 2,5) K; T = (50 2,5) K; T = (30 2,5) K. The standard rated thermal output results at T = 50 K. Inlet water
47、temperature t1: 75 C; Outlet water temperature t2: 65 C; Reference air temperature tr: 20 C. The standard low thermal output results at T = 30 K. BS EN 16430-2:2014EN 16430-2:2014 (E) 8 4.2.2.2 Influence of mass flow on the characteristic curve In case of an influence of the mass flow on the thermal
48、 output, it shall be estimated by performing all of the subsequent tests at standard mass flow and additionally at 50% and 200% of the standard mass flow. 4.2.2.3 Fan assisted radiators and convectors If the fans do not cover the entire radiator / convector, the performance of the radiator / convect
49、or is the sum of the performance of the basic units plus those of extension units. The basic unit is considered as the smallest combination of a regularly repeating radiator / convector section with fan(s). This basic section shall be indicated by the manufacturer. Examined is a combination of basic units of a length of at least 1 m (see 4.1). The performance of a basic unit is determined from this calculation. If the total length of all basic units is less than the total length of the radiator / convector, the standard
