EN ISO 13349:2010 (E) DIN EN ISO 13349:2012-07 3 Introduction This International Standard reflects the importance of a standardized approach to the terminology of fans. The need for an International Standard has been evident for som
24、e considerable time. To take just one example, the coding of driving arrangements differs from manufacturer to manufacturer. What one currently calls arrangement no. 1 can be known by another as arrangement no. 3. The confusion for the customer is only too apparent. For similar reasons, it is essent
25、ial to use standardized nomenclature to identify particular parts of a fan. Wherever possible, in the interests of international comprehension, this International Standard is in agreement with similar documents produced by Eurovent, AMCA, VDMA (Germany), AFNOR (France) and UNI (Italy). They have, ho
26、wever, been built on where the need for amplification was apparent. Use of this International Standard will lead to greater understanding among all parts of the air-moving industry. This International Standard is intended for use by manufacturers, consultants and contractors. EN ISO 13349:2010 (E) D

It is not applicable to electrical safety. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated

30、 and ISO 5801 and the following apply 3.1 Fans 3.1.1 fan rotary-bladed machine that receives mechanical energy and utilizes it by means of one or more impellers fitted with blades to maintain a continuous flow of air or other gas passing through it and whose work per unit mass does not normally exce
31、ed 25 kJ/kg NOTE 1 The term “fan“ is taken to mean the fan as supplied, without any addition to the inlet or outlet, except where such addition is specified. NOTE 2 Fans are defined according to their installation category, function, fluid path and operating conditions. NOTE 3 If the work per unit m
32、ass exceeds a value of 25 kJ/kg, the machine is termed a turbocompressor. This means that, for a mean stagnation density through the fan of 1,2 kg/m3, the fan pressure does not exceed 1,2 25 kJ/kg, i.e. 30 kPa, and the pressure ratio does not exceed 1,30 since atmospheric pressure is approximately 1
33、00 kPa. 3.1.2 bare shaft fan fan without drives, attachments or apperturbances See ISO 12759. EN ISO 13349:2010 (E) DIN EN ISO 13349:2012-07 5 3.1.3 driven fan impeller fitted to or connected to a motor, with or without a drive mechanism, a housing or a means of variable speed drive See ISO 12759. 3
34、.2 air abbreviated term for the expression “air or other gas” 3.3 standard air by convention, air with a density of 1,2 kg/m33.4 Fan installation categories according to the arrangement of ducting See Figure 1. 3.4.1 installation category A installation with free inlet and free outlet with a partiti

37、r D (see Figures 2, 3, 4 and 5). 3.5.2 partition fan fan used for moving air from one free space to another, separated from the first by a partition having an aperture in which or on which the fan is installed NOTE This fan can be arranged in installation category A (see Figure 6). EN ISO 13349:2010
38、 (E) DIN EN ISO 13349:2012-07 63.5.3 jet fan fan used for producing a jet of air in a space and unconnected to any ducting See Figure 7. NOTE The air jet can be used, for example, for adding momentum to the air within a duct, a tunnel or other space, or for intensifying the heat transfer in a determ
39、ined zone. 3.5.4 circulating fan fan used for moving air within a space which is unconnected to any ducting and is usually without a housing See Figure 8. 3.5.5 air curtain unit air moving device which produces an air curtain See Figure 30. 3.5.5.1 air curtain airstream directionally controlled airs
40、tream, moving across the entire height and width of an opening, which can reduce the infiltration or transfer of air from one side of the opening to the other, and inhibits insects, dust or debris from passing through 3.6 Types of fan according to the fluid path within the impeller 3.6.1 centrifugal
41、 fan fan in which the air enters the impeller with an essentially axial direction and leaves it in a direction perpendicular to this axis See Figure 2. NOTE 1 The centrifugal fan is also known as a radial-flow fan. NOTE 2 The impeller can have one or two inlet(s) and might include a shroud and/or a
42、backplate (centreplate) (see Figure 16). NOTE 3 The impeller is defined as “backward-curved or inclined”, “radial” or “forward-curved”, depending on whether the outward direction of the blade at the periphery is backward, radial or forward relative to the direction of the rotation (see Figures 9 and
43、 16). NOTE 4 A centrifugal fan can be of the low-, medium- or high-pressure type, according to the aspect ratio of fan inlet diameter to outside diameter of the impeller. These terms indicate that the pressure generated at a given flow rate is low, medium or high. NOTE 5 Figure 9 shows a cross-secti
44、on through a family of impellers having the same inlet diameter. Fans with ratios of fan inlet/outside impeller diameter of greater than approximately 0,63 mm are considered “low aspect ratio”, and lower than approximately 0,4 mm are considered “high aspect ratio”. Medium aspect ratio centrifugal fa
45、ns are intermediate between these two. NOTE 6 The impeller diameter and the casing scroll radii increase with the pressure range for which the fan is designed. NOTE 7 These categories are also affected by the ability to run at the necessary peripheral speed (see 5.2 and Table 1). EN ISO 13349:2010 (
46、E) DIN EN ISO 13349:2012-07 7 3.6.2 axial-flow fan fan in which the air enters and leaves the impeller along essentially cylindrical surfaces coaxial with the fan See Figure 3. NOTE 1 An axial-flow fan can be of the low-, medium- or high-pressure type, according to the aspect ratio of hub diameter t
47、o outside impeller diameter. These terms indicate that the pressure generated at a given flow rate is low, medium or high. NOTE 2 Figure 10 shows a cross-section through a family of impellers having the same outside diameter. Fans with ratios of hub/outside impeller diameter of less than approximately 0,4 mm are considered “low aspect ratio”, and greater than approximately 0,71 mm are considered “high aspect ratio”. Medium aspect ratio axial fans are intermediate between these two figures. NOTE 3 These categories are also affected by the ability
