29、 temperature and the mean water temperature 4 Testing of dry cooling capacity 4.1 Short description The dry cooling capacity of the test sample has to be determined in its steady state with measurements of the cooling water flow and the temperature difference in the cooling water. The dry cooling ca

30、pacity shall be quoted as a function of the temperature difference between the reference temperature and the average cooling water temperature. The test is carried out in a testing system according to EN 442-2, which consists of a closed booth with controlled temperatures of the inside surfaces and

31、a secondary master radiator for dry cooling capacity (see 4.4). All laboratories performing tests according to this standard shall participate in inter-laboratory comparison exercises (according to EN 442-2). To balance the dry cooling capacity, the test booth will be heated with a number of electri

32、cally heated dry cooling load simulators which are positioned on the floor of the test booth. To obtain reproducible results, the simulators shall be arranged according to 4.2. 4.2 Test booth The test is carried out in a test booth according to EN 442-2. In deviation from these definitions the surfa

33、ces, floor and ceiling of the test booth shall be insulated in such a way as that the average heat flow in those surfaces is lower than 0,40 W/m during the test. This heat flow shall be determined by preliminary calibration tests of the booth or by calculations. In deviation from EN 442-2, the refer

34、ence air temperature shall be 28 C 0,5 K during the measurement. The temperature of the metal surfaces under the insulation of the walls, floor and ceiling of the test booth shall be regulated and be maintained at a value, which is necessary to guarantee a max. temperature difference between these s

35、urfaces and the reference air temperature of less than 1,0 K. The radiant emissivity of the surface of the insulation shall be at least 0,9. The test booth will be heated with 10 electrically heated dry cooling load simulators (see Figure 1), which are positioned on the floor of the test booth. The

36、dimension of “a“ in Figure 1 depends on the thickness of the inner wall insulation. The output of each simulator shall not exceed 180 W and shall be continually variable. The housing of the simulators consists of painted sheet steel. The emissivity of the inside and outside surfaces shall be at leas

37、t 0,9. The active power of the simulators shall be measured using an instrument with an accuracy class of 1,0 or better.

40、442-2. Analogue to the excess temperatures given, the under temperatures shall be: T = (8 K 0,5) K T = (10 K 0,5) K T = (12 K 0,5) K DIN EN 16430-3:2015-03 EN 16430-3:2014(E)8 The under temperature is the difference between the reference room temperature and the mean water temperature: 2)(21tttTr+=

41、(1) Where: tr is the reference air temperature, t1 is the outlet water temperature, t2 is the inlet water temperature. The aim of the test is to establish the standard dry cooling capacity of a radiator etc. by determining the related values of dry cooling capacity and under temperature. Neither of

42、these quantities can be measured directly, but shall be calculated using the values of other measureable quantities, either directly or with additional information (calibration test, material properties table), by using mathematical relationships. The uncertainty in measuring the dry cooling capacit

43、y shall not exceed 25 W. 4.3.2 Fan assisted radiators / convectors If the fans do not cover the entire radiator / convector, the performance of the radiator / convector is the sum of the performance of base units plus those of any resulting residual length. The basic unit is considered to be the sma

44、llest combination of a regularly repeating radiator / convector section with fan(s). This basic unit shall be indicated by the manufacturer. A combination of basic units of a length of at least 1 m is examined. The performance of the basic unit is determined from this by calculation. The length of t

45、he sample under test shall be adapted if the requirements for the minimum dry cooling capacity according to 5.5 are not fulfilled. If the total length of all basic units is less than the total length of the radiator / convector the standard dry cooling capacity of the remaining length (difference) s

46、hall be determined with a fan speed of 0, see Figure 6 and Figure 7. If a fan acts on different lengths of a radiator / convector (e. g, a fan at the end of the radiator / convector), at least 3 lengths (shortest, medium, longest) shall be measured. Hence a linear characteristic is determined (see F

47、igure 8).
