本欧洲标准适用于非居住建筑物通风和室内空调系统的设计和实施，不包括工业过程等。它侧重于与这些系统相关的各种参数的定义。 本标准及其附件中的设计指导主要适用于机械供排气通风系统和混合通风系统的机械部分。 本标准不适用住宅通风用途。 CEN/TR 14788处理住宅建筑物通风系统的性能。 分类使用不同的类别。对于一些值，给出了示例，并且对于需求，呈现具有默认值的典型范围。本标准中给出的默认值不是规范性的，并且应该在没有指定其他值的情况下使用。分类应始终适用于建筑类型及其预期用途，如果不使用标准中给出的示例，则应分析基础。 注:不同的标准可能以不同的方式表示相同参数的类别，类别符号也可能不同

This European Standard applies to the design and implementation of ventilation and room conditioning systems for non-residential buildings subject to human occupancy, excluding applications like industrial processes. It focuses on the definitions of the various parameters that are relevant for such systems. The guidance for design given in this standard and its annexes are mainly applicable to mechanical supply 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 ventilation systems in residential buildings are dealt with in CEN/TR 14788. 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 standard are not normative as such, and should 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. NOTE Different standards may express the categories for the same parameters in a different way, and also the category symbols may be different.
