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 ?s,c seasonal coefficient of performance SCOP, SCOPon and SCOPnet, and seasonal space heating energy efficiency ?s,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.
