35、characteristics 4.1 Flow rate/pressure 4.1.1 Principle This test consists of measuring several volume flow rates induced through a device by the applied static pressure difference to define the flow rate/pressure characteristic curve in the operating range specified by the manufacturer. In the case
36、of manually adjustable devices this test shall be carried out at maximum and minimum opening conditions specified by the manufacturer. Some exhaust ATD are of the bi-function type, i.e. they are designed to work under both natural and mechanical ventilation system. In that case the manufacturer may
37、have to specify two operational ranges, and the device shall be tested for each of them according the standard procedure. 4.1.2 Test installation, conditions and uncertainty of measurement 4.1.2.1 Test installation and conditions The device to be tested shall be installed in accordance with Figure 2
38、a) for exhaust air terminal device or Figure 2b) for supply air terminal device. The test installation shown in Figure 2a) and Figure 2b) comprises: a test duct with an airflow meter, a static pressure gauge and an airflow straightener in accordance with ISO 5221. Other measurement devices may be us
39、ed, provided they allow measurements with an uncertainty in accordance with 4.1.2.2; a fan with means to vary the pressure difference across the device, covering the range of Table 1 given in 4.1.3. NOTE In order to avoid pumping effect, an adequate device may be added after the airflow meter. BS EN
40、 13141-2:2010EN 13141-2:2010 (E) 8 The test facilities shall have a range: for extraction: 300 Pa to 0 Pa; for supply: 0 Pa to + 300 Pa. The air terminal device shall be mounted in a test duct with cross-sectional dimensions equal to the nominal size of the device or to the duct dimensions normally
41、recommended by the manufacturer. For supply only, the duct shall be straight and at least 20 Delong to guarantee a uniform velocity profile or shall include an efficient flow straightener located at a position at least 3 Defrom any part of the air terminal device. It is recommended that straightener
42、 cells have an axial length at least equal to six times the hydraulic diameter of their cross-section. a) For exhaust air terminal device b) For supply air terminal device Key 1 airflow 7 flow straightener 2 airflow meter 8 connection to fan, flowrate control and airflow meter 3 plane of temperature
