BS EN 162821:2017EN 16282-1:2017 (E) 4 1 Scope This European Standard specifies general requirements, such as ergonomic aspects in relation to ventilation of the kitchen (temperature, air aspects, moisture, noise, etc.)
29、, including a method for calculating the airflows. This European Standard is applicable to ventilation 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 prepar
30、ed, where tableware and equipment is washed, cleaned and food is stored. This European Standard is applicable to kitchen ventilation systems except those in domestic kitchens. Unless otherwise specified, the requirements of this standard should be checked by way of inspection and/or measurement. NOT

41、on of odours, pollutants and humidity so the indoor air quality shall not be affected negatively. If the extract and supply airflows are designed according to this standard, this requirement concerning the air quality is assumed to be fulfilled. The ventilation system shall be capable of separating
42、aerosol from the extract air. NOTE Extract and supply air systems are necessary in commercial kitchens because: the air is polluted by odours, particles of fat and gaseous products of combustion and other particulates, this pollution needs to be removed; indoor air quality needs to be suitable for p
43、eoples health, hygiene and comfort; heat is created to a considerable extent due to convection and radiant heat and this heat needs to be kept at an acceptable level; moisture is created by various kitchen processes and this moisture needs to be kept at an acceptable level; it is necessary to renew
44、the air in the rooms by an exchange with outside air and maintain comfortable or specified room air conditions. 5 Classification of kitchens Kitchens are classified according to the following features: spatial arrangement of appliances; types of meal preparation; number of portions to be prepared wi
45、thin the time limit; variety of meals to be prepared; work sequence; The kitchen shall be classified in accordance with Table A.2 in normative Annex A. The following are possible ways of connecting the kitchen to the meal dispatch point: kitchens with a directly-connected meal dispatch point to the
46、dining room; kitchens with a separately-arranged meal dispatch point or with a distribution kitchen; BS EN 162821:2017EN 16282-1:2017 (E) 7 kitchens within dining areas without a spatial separation, e.g. snack bars etc. There are zones within kitchens which can be subject to special hygiene needs. T
47、hese are for example. cold areas; hot areas; meat preparation areas; fish preparation areas; meal dispatched areas. 6 Design principles 6.1 General requirements Kitchens with kitchen equipment of a nominal power supply exceeding 25 kW shall have mechanical extract and supply air. All other kitchens
48、shall have at least a mechanical exhaust air system (one passive air inlet may be tolerated). NOTE 1 Please note the possible existence of National regulations regarding exhaust and supply air to kitchens. NOTE 2 Typical kitchen equipment emitting critical air pollution: Dish Washer; Microwave Oven/
49、Toaster; Bains Marie/Hot Cupboard; Induction Hob/Glass ceramic hob; Pastry/Bakery Oven; Oven; Boiling Pan/Tilting Kettle; Bratt Pan/Tilting Skillet; Open Top Range and Oven; Griddle; Fryer; Rotisserie; Chain Broiler (Burger Conveyor); Salamander/Steak Grille; Chargrille/Charbroiler; Wok Range.
