The standard focuses onthe system-aspectsfor typical applications and covers the following: Aspects important to achieve and maintain a good energy performance in the systems withoutanynegative impact on the quality of the internal environment. Relevant parameters o

27、andard applies to the design and implementation of ventilation and roomconditioning systems for non-residentialbuildings subject to human occupancy, excludingapplicationslike industrial processes. It focuses on the definitions of the various parameters that are relevant forsuch systems.The guidance
28、for design given in this standard and its annexes are mainly applicable to mechanicalsupply and exhaust ventilation systems, and the mechanical part of hybrid ventilation systems.Applications for residential ventilation are not dealt with in this standard. Performance of ventilationsystems in reside
29、ntial buildings are dealt with in CEN/TR 14788. The classification uses different categories. For some values, examples are given and, forrequirements,typical ranges with default values are presented. The default values given in thisstandard are not normative as such, and should be usedwhere no othe
30、r values are specified.Classification should always be appropriate to the type of building and its intended use, and the basisof the classification should be explained if the examples given in the standard are not to be used.NOTE Different standards may express the categories for the same parameters
31、 in a different way, and also the category symbols may be different. 2 NormativereferencesThe following referenced documents are indispensable for the application of this document.

39、occupancyand is definedas a volume of air that is confined by specified horizontal and vertic al planesNOTE1 The verticalplanes are usually parallel with the walls of the room. Usually there is also a limit placed on the height of the occupied zone. Thus, the occupied zone in a room is that space in
40、 which the occupants are normally located and where the requirements for the indoor environment shall be satisfied. Definitions are givenin 7.2. NOTE2definition of the occupied zone is dependent on the geometry and the use of the room andshould bespecified case by case 3.4ventilation effectiveness r

It is defined asSUPIDASUPETAv cccc= (1) where: v is the ventilation effectivenessc ETA is the pollution concentration in the extract air in mg.m-3c I DA
42、 is the pollution concentration in the indoor air (breathing zone within the occupied zone)in mg.m-3c SUP is the pollution concentration in the supplyair in mg.m-3NOTE1The ventilation effectiveness depends on the air distribution and the kind and location of the airpollution sources in the space. It
43、 may therefore have different values for different pollutants. If there is completemixing of air and pollutants, the ventilation effectiveness is one. BS EN 13779:2007EN 13779:2007 (E)8 NOTE 2 Further information on ventilation effectiveness is given in Annex E and CR 1752.NOTE 3 Another term freque
44、ntly used for the same concept is “contaminant removal effectiveness”.3.5specific fan power for the building or the whole system (SFP) is the combined amount of electric power consumed by allthe fans in the air distribution system divided by the total airflow rate through the building underdesign lo

It is related to an air density of 1,2 kg.m-3. It should be taken into account that the designperformance is not usually the rated maximum pe
47、rformance of the ventilation components, but typically between40 and 60 % of the maximumperformance.NOTE 2 Further guidance for the applications, calculation and validation of the specific fan power is presentedin Annex D.3.6demand controlled ventilation ventilation system where the ventilation rate
48、 is controlled by air qualit y, moisture, occupancyor some other indicator for the need of ventilation 3.7ventilation system combination of appliances designed to supplyinteriorspaces with outdoor air and to extract polluted indoor airNOTE The system can consist of mechanical components (e.g. combin
49、ation of air handling unit, ducts andterminal units). Ventilation system can also refer to natural ventilation systems making use of temperaturedifferences and wind with facade grills in combination with mechanical exhaust (e.g. in corridors, toilets etc.).Both mechanical and natural ventilation can be combined with operable windows. A combination of mechanicaland non-mechanical components is possible (hybrid systems). BS EN 13779:2007EN 13779:2007 (E)9 4 Symbols and units For the purposes of this document, the symbols and unit
