21、 and room-conditioning systems EN 12097:2006 (E) 5 3 Definition and symbols For the purposes of this document the terms definitions given in EN 12792:2003 and the following apply. 3.1 Access panel permanent duct component intended to permit access into ducts for inspection and maintenance. An access

22、 panel according to this standard can be opened and closed repeatedly, without cutting or damaging the duct. Refer to “Door and inspection panel” in EN 12792 4 Requirements 4.1 General The air distribution system shall be designed, manufactured and installed in such a way that cleaning of internal s

23、urfaces and components is possible. The design and installation documentation shall indicate by dimensions, the location of all access components and provide details of the size and type of component required. The documentation shall also indicate the location of the components mentioned in 4.3 to e

24、nable proper service and re-adjustment. The cleaning method may vary depending on the category of the air distribution system. The arrangements for cleaning depend on the category of air system, as specified in EN 13779. This category influences the frequency of access covers, the method for cleanin

25、g and the cleaning intervals. All equipment or components inside the ductwork that inhibits cleaning shall be avoided. Stiffeners, or other equipment necessary inside the ducts shall be smooth. Sufficient free space shall be provided around the ductwork so that cleaning operations can be carried out

26、 without obstruction. The requirements for the strength and air tightness of ducts equipped with access components shall conform to those for the whole ductwork, as specified in EN 12237 and in EN 1507. The requirements for strength of ductwork hangers and supports shall conform to EN 12236. For duc

27、twork in dimensions unsuited for mechanized cleaning and where human access is needed, the type and location of access components shall allow the cleaning person to safely and without hindrance enter and exit from the ducts. 4.2 Openings 4.2.1 General Covers, access panels and doors shall be easy to

28、 open. All access components shall be constructed and installed to match the performance, including air tightness and strength, of the system and facilitate the cleaning process. In ductwork where thermal, acoustic or fire insulation is specified, the design documentation shall define how the insula

29、tion value is maintained across the opening. Access components shall be constructed and installed in the ductwork such that the integrity of the thermal, acoustic or fire insulation is maintained. EN 12097:2006 (E) 6 A duct-mounted component, which may be dismounted for cleaning may also be regarded

30、 as an opening, provided it fulfils the requirements stated for openings. 4.2.2 Installation and location of openings Consideration shall be given to the security of access panels and doors installed in public areas. Detachable access panels and doors shall be secured to prevent them from causing in

31、jury or falling into the duct. Access components shall be provided to ensure that the whole ductwork system can be cleaned (see 4.4). Unobstructed access to the access panels of the ducts shall be provided. See annex A. 4.2.3 Dimensions 4.2.3.1 General Unless cleaning conditions are specified in tec

32、hnical agreement, the dimensions shall conform to 4.2.3.2 and 4.2.3.4. Openings could reduce the stability of ducts. This should be prevented by an adequate fixing. 4.2.3.2 Openings for rigid circular ducts For cleaning access, the ducts shall be provided either with openings of sizes according to T

33、able 1 and Figure 2 or T-pieces with removable end caps with a minimum nominal diameter (EN 1506) according to Table 1 and Figure 2. Table 1 Access panels in circular ducts, minimum dimensions Rectangular or oval opening Branch/T-piece + end cap with minimum diameter Duct diameter nominal (mm) D Min

35、r side 4.2.3.2 (Openings for rigid circular ducts) applies. For access panels fitted to the flat side 4.2.3.4 (Openings for rectangular ducts) applies. 4.3 Duct-mounted components For duct-mounted components that cannot be cleaned through without obstruction, access according to 4.4 shall be provide

36、d from both sides, or it shall be possible to remove the component for maintence. Examples of such components are: adjustment and shut-off dampers; fire dampers; heating and cooling coils; humidifiers; sound attenuators with internal pods or baffles; filter sections; in-duct fans; heat recovery devi

37、ces; air flow control devices; air turning vane. NOTE If a component is to be removed for service, the service instructions shall include sufficient guidance for the checking its function. Airflow direction shall be labelled on all these components and they shall be installed in such a way, that the

38、 intended removal, servicing or inspection is possible. If re-setting of equipment, e.g. fire damper or controller, inside a duct is required, the access panel shall be located to allow the necessary work and inspection. EN 12097:2006 (E) 9 4.4 Location and frequency of access panels The ductwork sh

39、all be equipped with sufficient access panels in order to ensure that no part of the ductwork is located with more than: a) one dimensional change from an access panel; b) one change of direction of more that 45 from an access panel; c) 7,5 meters of duct from an access panel. NOTE The top and botto

40、m of vertical risers should be equipped access panels. Flexible ductwork shall be complemented with rigid access components at a minimum of every 6 m. 4.5 Screws and rivets It is accepted that screws or preferably rivets used during installation intrude into the ductwork, provided that they do not o

41、bstruct cleaning and maintenance. Screws of maximum length 13 mm may be used. Sharp pointed screws shall not be used nearby openings where they can cause injury to persons. They are therefore not to be used within a distance of 1 m from terminal devices or access panels. When mounting access panels

42、in old ductwork, existing screws within 1 m from the access opening shall be replaced with rivets. EN 12097:2006 (E) 10 Annex A (informative) Service and access recommendations An example of access to service openings is given in Figure A.1. Care should be taken to avoid that access panels later are

43、 found to be inaccessible. Special consideration should be given to the practical problems associated with gaining personnel access to heavily congested ceiling areas and multi-layered ductwork systems.
