Definitions/Units of Measure/Symbols 3.1 Definitions 3.1.1 Fan A device that uses a power-driven rotating imp
15、eller to move air or gas (see note below). The internal energy increase imparted by a fan to air is limited to 25 kJ/kg (10.75 Btu/ lbm). This limit is approximately equivalent to a pressure of 30 kPa (120 in. wg) (AMCA 99-0066). Note: for the purpose of this standard, the term “air“ is used in the
16、sense of “gaseous fluid.“ 3.1.2 Fan inlet and outlet boundaries The interfaces between a fan and the remainder of the air system; the respective planes perpendicular to an airstream entering or leaving a fan. Various appurtenances (inlet boxes, inlet vanes, inlet cones, silencers, screens, rain hood
17、s, dampers, discharge cones, evass, etc.), may be included as part of a fan between the inlet and outlet boundaries. 3.1.3 Fan input power boundary The interface between a fan and its drive. When mechanical input power is reported, it is the interface between a fan and its drive, which in this conte
18、xt is either a dynamometer or calibrated motor. When electrical input power is reported, it is the interface between mains and the drive. 3.1.4 Driven fan A fan equipped with a drive. 3.1.5 Drive Components used to power the fan, such as a motor, motor control and transmission. Not all of these comp
19、onents are required to constitute a drive. A calibrated motor used to measure fan input power is generally not considered part of the drive. 3.1.6 Transmission A system that transmits mechanical power from the motor to the fan shaft. Examples of transmissions are belts/sheaves, couplings and gears.
20、3.1.7 Fan outlet area The gross inside area measured in the planes of the outlet openings. 3.1.8 Fan inlet area The gross inside area measured in the planes of the inlet connections. For converging inlets without connection elements, the inlet area shall be considered to be that where a plane perpen
21、dicular to the airstream first meets the mouth of the inlet bell or inlet cone. 3.1.9 Dry-bulb temperature Air temperature measured by a temperature-sensing device without modification to compensate for the effect of humidity (AMCA 99-0066). 3.1.10 Wet-bulb temperature The air temperature measured b
22、y a temperature sensor 2 | ANSI/AMCA 210-16 ANSI/ASHRAE 51-16 covered by a water-moistened wick and exposed to air in motion (AMCA 99-0066). 3.1.11 Wet-bulb depression The difference between the dry-bulb and wet-bulb tempera- tures at the same location (AMCA 99-0066). 3.1.12 Stagnation (total) tempe
23、rature The temperature that exists by virtue of the internal and kinetic energy of the air. If the air is at rest, the stagnation (total) temperature will equal the static temperature (AMCA 99-0066). 3.1.13 Static temperature The temperature that exists by virtue of the internal energy of the air. I
24、f a portion of the internal energy is converted into kinetic energy, the static temperature is decreased accordingly. 3.1.14 Air density The mass per unit volume of air (AMCA 99-0066). 3.1.15 Standard air Air with a standard density of 1.2 kg/m 3(0.075 lbm/ft 3 ) at a standard barometric pressure of
25、 101.325 kPa (29.92 in. Hg). 3.1.15.1 Standard air properties Standard air has a ratio of specific heats of 1.4 and a viscos- ity of 1.8185 10 -5Pas (1.222 10 -5lbm/fts). Air at 20C (68F) temperature, 50% relative humidity, and standard barometric pressure has the properties of standard air, approxi
26、mately. Note: The values of the standard air density in the SI and I-P systems of units are not exactly equivalent. This may have an impact on the accuracy of the fan performance data when the data is shown in both systems of units or converted from one system to the other. 3.1.16 Pressures in the a
27、ir The pressures in the air relevant to the fan performance testing have dimension as a force per unit of area. These pressures also have a meaning of specific energy defined as energy per volume of the air or specific power defined as power per unit of the airflow. In either case, the result- ing d
28、imension is the same. The pressures in the SI system are expressed in Pa, while in the I-P system they are expressed as inches of water or mercury. The conventional conversion of 1 in. of water equals 249.089 Pa (see note below). Pressures in inches of mercury are referenced to the mercury density o
29、f 13595.08 kg/m 3in the SI system or 848.656 lbm/ft 3in the I-P system. Note: This conventional conversion is based on water density of 1000 kg/m 3in the SI system or 62.427 lbm/ft 3in the I-P system. 3.1.17 Absolute pressure The pressure when the datum pressure is absolute zero. It is always positi
30、ve. 3.1.18 Barometric pressure The absolute pressure exerted by the atmosphere. 3.1.19 Gauge pressure The differential pressure when the datum pressure is the barometric pressure at the point of measurement. It may be positive or negative. 3.1.20 Total pressure The air pressure that exists by virtue
31、 of the state of the air and the rate of motion of the air. It is the algebraic sum of velocity pressure and static pressure at a point. If air is at rest, its total pressure will equal the static pres- sure. 3.1.21 Dynamic (velocity) pressure The portion of air pressure that exists by virtue of the
32、 rate of motion of the air. 3.1.22 Static pressure The portion of air pressure that exists by virtue of the state of the air. If expressed as a gauge pressure, it may be positive or negative. 3.1.23 Pressure loss A decrease in total pressure due to friction and/or turbulence. 3.1.24 Fan air density
33、The density of the air corresponding to the total pressure and the stagnation (total) temperature of the air at the fan inlet. 3.1.25 Fan airflow rate The volumetric airflow rate at fan air density. 3.1.26 Fan total pressure The difference between the total pressure at the fan outlet and the total p
34、ressure at the fan inlet. 3.1.27 Fan dynamic (velocity) pressure A pressure calculated from the average air velocity and air density at the fan outlet. 3.1.28 Fan static pressure The difference between the fan total pressure and the fan dynamic (velocity) pressure. Therefore, it is the difference AN
