In order to choose the appropriate fan, it is necessary to know its performance characteristics, given as the volume flow rate as a function of fan pressure. These characteristics are strongly influenced by upstream flow conditions (velocity profile, possible presence of a swirl and wind). Downstream conditions do not usually affect the fan operation, but the nature of flow downstream from the fan, especially the swirl, can have an effect on pressure losses in the circuit and should be taken into account during installation design. The four following categories of installations are defined in EN ISO 5801: SIST EN 13141-11:2015
EN 13141-11:2015 (E) 10 — category A: free inlet and free outlet; — category B: free inlet and ducted outlet; — category C: ducted inlet and free outlet; — category D: ducted inlet and ducted outlet. For each category, EN ISO 5801 defines the installation in the immediate proximity of the fan, as well as the position of the pressure measurement. Test installation and conditions are described in EN 13141-4. 6.2 External leakage Pressure method applies to classify external leakage by using Table 2. External leakage tests shall only be applied to products intended to be connected in a category C or category D configuration. Table 2 — External leakage classification – pressure method Class Pressurization test External leakage Centralised unit for whole dwelling Single Room (at 150 Paa) (at 50 Paa) % % A1 ≤ 2 ≤ 2 A2 ≤ 5 ≤ 5 A3 ≤ 10 ≤ 10 not classified > 10 > 10 a Pressure at which the external leakage test is performed at. This test pressure depends on the type of unit tested. The external leakage shall be measured according to Annex D. The external leakage air volume flow qve at over and/or under pressure, according to Table 2, shall be measured and reported as such and also compared to the declared maximum air volume flow of the unit as a percentage. If all components (filters, battery, etc.) are situated: — upstream of the fan, the external leakage should be measured under pressure; — downstream of the fan, the external leakage shall be measured in over pressure; — on either side of the fan, the external leakage shall be measured in over and under pressure. During the pressurization tests for external leakage, the fan of the unit under tes
