本欧洲标准涵盖了冷却发电系统的运行参数和能耗的计算。冷却代码包括: - 冷却发电机，如压缩和吸收式冷水机组; - 其他（通用）发电机类型，例如地面或地表水或直接使用钻孔的地热;和 - 不同类型的排热（干燥，潮湿，与室外空气混合，其他水槽类型）。 方法涵盖: - 通过使用与M3-1标准的接口，热回收的可能性被排除以供加热和/或家用热水生产使用;和 - 多发生器计算。 该文件不包括分别由模块M4-5，M4-6和M4-7标准涵盖的散热，分配和存储系统。它直接连接到冷却系统的一般部分，即M4-1标准。 表1显示了在prEN ISO 52000 1:2015中规定的模块化结构范围内，本标准在EPB标准集中的相对位置。 注1:在FprCEN ISO/TR 52000 2中，可以找到相同的表格，每个模块的相关EPB标准和相关技术报告的编号已经发布或正在准备中。 注2:

This European Standard covers the calculation of the operational parameters and the energy consumption of cooling generation systems. The cooling generation consists of: - cooling generators like compression and absorption chillers; - other (generic) generator types such as ground or surface water or direct use of ground heat from boreholes; and - different types of heat rejection (dry, wet, hybrid with outdoor air, other sink types). The methods cover: - the possibility of heat recovery of heat to be rejected for the use of heating and/or domestic hot water production, through the use of an interface to the M3-1 standard; and - a multi generator calculation. The document does not cover the cooling emission, distribution and storage systems, which are covered by the Module M4-5, M4-6 and M4-7 standards, respectively. It is directly connected to the general part of the cooling systems, the M4-1 standard. Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1:2015. NOTE 1 In FprCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying Technical Reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1. Table 1 - Position of this standard (in casu M4–8) within the modular structure of the set of EPB standards .
