本欧洲标准适用于作为工厂制造的单组件的水力风机盘管单元（FCU），其提供冷却和/或加热功能，但不包括冷却或加热源。 该标准涵盖无空气输送和空气管道单元，由于管道电阻最大为120 Pa，具有最大的外部静压力。 本欧洲标准提供了确定风机盘管单元的声学性能，确定标准工作条件和安装的方法。 指定用于生产或现场测试的测试不是本标准的目的。 注意为了剩余的条款，术语“单位”用于表示“FprEN 1397:2015”3.1中定义的“线圈单位”

This European Standard applies to hydronic fan coil units (FCU) as factory-made single assemblies which provide the functions of cooling and/or heating but do not include the source of cooling or heating. The standard covers both air free delivery and air ducted units with a maximum external static pressure due to duct resistance of 120 Pa max. This European Standard provides methods for the determination of the acoustical performance of fan coil units, defining standard working condition and installation. It is not the purpose of this standard to specify the tests used for production or field testing. NOTE For the purpose of remaining clauses, the term “unit” is used to mean “fan coil unit” as defined in 3.1 of FprEN 1397:2015.
