(Main)Ventilation for non-residential buildings - Performance requirements for ventilation and room-conditioning systems
Ventilation for non-residential buildings - Performance requirements for ventilation and room-conditioning systems
This document applies to the design of ventilation and room conditioning systems for non-residential build-ings subject to human occupancy. It focuses on the definitions of the various parameters that are relevant for such systems. Naturally ventilated buildings are outside the scope of this document.
The classification uses different categories. For some values, examples are given and, for requirements, typical ranges with default values are presented. The default values given in this document shall be used where no other values are specified. Classification should always be appropriate to the type of building and its intended use, and the basis of the classification should be explained if the examples given in the standard are not to be used. National regulations must always be followed, even when they are out of the range given in this document.
Lüftung von Nichtwohngebäuden - Allgemeine Grundlagen und Anforderungen an Lüftungs- und Klimaanlagen
Dieses Dokument gilt für Planung, Bau sowie Betrieb von Lüftungs- und Klimaanlagen in Nichtwohnge-bäuden, die für den Aufenthalt von Menschen bestimmt sind. Es enthält die Definitionen der Parameter, die für derartige Anlagen relevant sind. Wohngebäude sowie Gebäude mit freier Lüftung liegen nicht im Anwendungsbereich dieses Dokuments.
Bei der Klassierung wird eine Einteilung in unterschiedliche Kategorien vorgenommen. Für einige Werte sind Beispiele angegeben, und für Anforderungen sind übliche Bereiche mit Standardwerten angegeben. Die in diesem Dokument angegebenen Standardwerte sind anzuwenden, wenn für ein Projekt keine anderen Werte festgelegt sind. Die Klassierung sollte stets dem Typ und der vorgesehenen Nutzung des Gebäudes entsprechen; wenn die in diesem Dokument angegebenen Beispiele nicht angewendet werden, sollte die Klassierungsgrundlage erläutert werden. Nationale Vorschriften sind stets zu befolgen, selbst wenn diese außerhalb des in diesem Dokument angegebenen Bereiches liegen.
Ventilation des bâtiments non résidentiels - Exigences de performances des systèmes de ventilation et de conditionnement d'air
Le présent document s'applique à la conception de systèmes de ventilation, de conditionnement d'air et de climatisation de pièce pour les bâtiments non résidentiels sujets à occupation humaine. Il porte surtout sur les définitions des divers paramètres intéressant de tels systèmes. Les bâtiments ventilés naturellement sont exclus du présent document.
La classification regroupe des catégories différentes. Des exemples sont donnés pour quelques valeurs, et des niveaux types avec des valeurs par défaut sont indiqués pour les exigences. Les valeurs par défaut données dans le présent document ne doivent être utilisées que si aucune autre valeur n'est spécifiée. Il convient que la classification soit toujours appropriée au type du bâtiment et à son utilisation présumée, et que le fondement de la classification soit expliqué. Les exemples de la présente norme ne doivent pas être utilisés. Les règlements nationaux doivent toujours être suivis, même s'ils sont en dehors des niveaux donnés dans le présent document.

is the ventilation effectiveness
cEHA
is the pollution concentration in the exhaust air
cIDA is the pollution concentration in the indoor air (breathing zone within in the occupied zone)
cSUP
is the pollution concentration in the supply air The ventilation effectiveness depends on the air distribution and the kind and location of the air pollution sources in the space. It may therefore have different values for different pollutants. If there is complete mixing of air and pollutants, the ventilation effectiveness is one. Further information on ventilation effectiveness is given in CR 1752. NOTE: Another term frequently used for the same concept is “contaminant removal effectiveness”. 3.5 Specific fan power The specific power of each fan is defined as totvSFPpη∆==qPP (2) where PSFP
is the specific fan power in W.m-3.s
P
is the input power of the motor for the fan in W
qv
is the nominal airflow through the fan in m3.s-1
∆p is the total pressure difference across the fan
ηtot is the total efficiency of fan, motor and drive in the built-in situation. The coefficient is valid for the nominal airflow with clean filter conditions any bypasses closed. It is related to an air density of 1,2 kg.m-3. 4 Symbols and Units For the purposes of this document, the symbols and units given in Table 1 shall apply. The units in brack-ets are also in use.

5.1 Specification of types of air The types of air in a building and in a ventilation or air-conditioning system are specified in Table 2 and il-lustrated in Figure 1. The abbreviations and colours given in Table 2 shall be used to mark the type of air in drawings of ventilation or air-conditioning systems. The abbreviations can also be helpful for the label-ling of system parts. Where there is a free choice of the language, the use of English is recommended. The colour code of the supply air is chosen according to the system-controlled functions in accordance with Table 15.
