BS EN 14825:2022
This standard BS EN 14825:2022 Air conditioners, liquid chilling packages and heat pumps, with electrically driven compressors, for space heating and cooling, commercial and process cooling. Testing and rating at part load conditions and calculation of seasonal performance is classified in these ICS categories:
This document is applicable to 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 exchange-to-water(brine) heat pumps (DX-to-water(brine)) as defined in EN 15879-1. This document also applies to hybrid units as defined in this standard. This document specifies the temperatures, 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, seasonal space heating energy efficiency ηs,h and seasonal energy performance ratio SEPR. Such calculation methods can be based on calculated or measured values. In case of measured values, this document specifies the test methods for determination of capacities, EER and COP values during active mode at part load conditions. It also establishes test methods for power input 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 "heating" is used to refer to space heating.
