This European standard covers air conditioners, heat pumps and liquid chilling packages. It applies to factory made units defined in EN 14511-1, except single duct, control cabinet and close control units.
This standard gives the calculation methods for the determination of reference seasonal energy efficiency
SEER and SEERon and reference seasonal coefficient of performance SCOP, SCOPon and SCOPnet.
Such calculation methods may be based on calculated or measured values.
This standard serves as an input for the calculation of the system energy efficiency in heating mode of specific heat pump systems in buildings, as stipulated in the standard EN 15316-4-2.
