该欧洲标准涵盖空调，热泵和液体冷冻包装，包括舒适和加工制冷机。它适用于EN 14511-1中定义的工厂制造的单元，单管，双管，控制柜和关闭控制单元除外。它还涵盖了EN 15879-1定义的直接膨胀水（盐水）热泵（DX-水）。 本欧洲标准还包括本标准中定义的混合式热泵。 本欧洲标准给出了温度和部分负荷条件以及季节能效SEER和SEERON的确定的计算方法，季节性空间冷却能效η，c季节性能SCOP，SCOPon和SCOPnet的季节性系数以及季节性空间加热能效率α，h和季节能量性能比SEPR。 这种计算方法可以基于计算值或测量值。 在测量值的情况下，本欧洲标准涵盖在部分负载条件下在活动模式期间确定容量，EER和COP值的测试方法。它还涵盖了恒温关闭模式，待机模式，关闭模式和曲轴箱加热器模式下的电力消耗测试方法。 注1使用单词“unit”而不是产品的全部条款。 注2:“冷却”一词用于

This European Standard covers air conditioners, heat pumps and liquid chilling packages, including comfort and process chillers. It applies to factory made units defined in EN 14511-1, except single duct, double duct, control cabinet and close control units. It also covers direct expansion-to-water(brine) heat pumps (DX-to-water) as defined in EN 15879-1. This European Standard also covers hybrid heat pumps as defined in this standard. This European Standard gives the temperatures and part load conditions and the calculation methods for the determination of seasonal energy efficiency SEER and SEERon, seasonal space cooling energy efficiency ηs,c seasonal coefficient of performance SCOP, SCOPon and SCOPnet, and seasonal space heating energy efficiency ηs,h and seasonal energy performance ratio SEPR. Such calculation methods may be based on calculated or measured values. In case of measured values, this European Standard covers the test methods for determination of capacities, EER and COP values during active mode at part load conditions. It also covers test methods for electric power consumption during thermostat-off mode, standby mode, off-mode and crankcase heater mode. NOTE 1 The word "unit" is used instead of the full terms of the products. NOTE 2 The word "cooling" is used to refer to both space cooling and process cooling. NOTE 3 The word "heating" is used to refer to space heating.
