本欧洲标准适用于制冷操作的非管道式空气冷却器: a）制冷剂的直接干膨胀; b）通过制冷剂的泵循环液体过量供给; c）用液体。 本标准规定了统一的绩效评估方法，以测试和确定以下内容: - 产品识别; - 标准能力; - 标准液压降; - 标准制冷剂压降（仅通过泵循环进行液体过量运行）; - 额定空气流量; - 额定风扇功率 它不包括符合性的评估。 它不适用于空气冷却器用于管道安装或自然空气对流。 本标准不包括技术安全方面

This European Standard is applicable to non-ducted unit air coolers for refrigeration operating: a) with direct dry expansion of a refrigerant; b) with liquid overfeed by pump circulation of a refrigerant; c) with a liquid. This standard specifies uniform methods of performance assessment to test and ascertain the following: - product identification; - standard capacity; - standard liquid pressure drop; - standard refrigerant pressure drop (for operation with liquid overfeed by pump circulation only); - nominal air flow rate; - nominal fan power. It does not cover evaluation of conformity. It is not applicable to air coolers for duct mounting or with natural air convection. This standard does not cover technical safety aspects.
