BS EN 162825:2017EN 16282-5:2017 (E) 4 1 Scope This European Standard specifies requirements for the design, construction and operation of the air duct in commercial kitchens, including technical safety, ergonomic and hygienic features. This European Standard is applicable to venti
27、lation systems in commercial kitchens, associated areas and other installations processing foodstuffs intended for commercial use. Kitchens and associated areas are special rooms in which meals are prepared, where tableware and equipment is washed, cleaned and food is stored and food waste areas. Th
28、is European Standard is applicable to kitchen ventilation systems except those used in domestic kitchens. A method of verification of each requirement is also specified. Unless otherwise specified, the requirements of this standard should be checked by way of inspection and/or measurement. NOTE Plea
29、se note the possible existence of additional or alternative local national regulations on installation, appliance requirements and inspection, maintenance and operation. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispens

34、 fumes through air ducts, alone or together with other elements, for a specified period of time BS EN 162825:2017EN 16282-5:2017 (E) 5 3.3 outside air air drawn from outside the building 3.4 air leakage class measure for the air leakage of an air duct system, defined by the upper limit of the air le
35、akage rate Note 1 to entry: The air leakage of air ducts is classified in accordance with EN 12237. 3.5 fire resistance period minimum time in minutes which an element of the ventilation air ducts meet the specified requirements 3.6 outlet air air discharged to the outside (positive pressure) 3.7 ai

39、.2.1 General Air ducts shall be planned and constructed in such a way to ensure low energy consumption, low leakage, low heat loss and favourable sanitary conditions during their operation. Any adverse hygienic effects of the food shall be avoided. The stability of the air ducts, their connection an
40、d mounting elements shall be dimensioned appropriately to ensure that it will permanently withstand the stress and load caused by operation. Flexible supply air ducts shall be avoided as far as possible due to difficulty in cleaning. 4.2.2 Design and loss of pressure Air ducts shall be designed in s
41、uch a way to ensure minimum loss of pressure. This may be achieved by: a) longitudinal and cross-connections which are flush at the inside, b) stiffening elements that are placed on the outside to avoid high air resistance, c) air rerouting without sharp edges, inner radius at least 100 mm, junction
42、s preferably with guiding elements, d) no sudden changes in cross section, e) in the case of changes in the cross-sectional angle of inclination shall be less than 45 f) smooth internal walls and joints. 4.2.3 Special requirements for extract and outlet air ducts Extract and outlet air ducts and the
43、ir connections shall be aerosol-proof and visible escape of aerosol is not permitted. Soldered/brazed or welded connections or connections with permanently elastic and aerosol-resistant sealing materials are deemed appropriate and may be used. The use of flexible air ducts is not permitted. Chinaman

The surface of silencers shall be abrasion-proof, smooth, easy to clean and when installed in extract and outgoing air ducts they shall be liquid-proof, water-resis
47、tant, and resistant to aerosol. Silencers shall be packaged appropriately for transport and storage to avoid any contamination. It shall be possible to dismantle silencers using basic tools. 4.2.6 Dimensioning of air ducts 4.2.6.1 Flow velocity guide values For dimensioning of air ducts, the flow ve
