  2. Seasonal energy efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/Seasonal_energy_efficiency...

    Typical EER for residential central cooling units = 0.875 × SEER. SEER is a higher value than EER for the same equipment. [1] A more detailed method for converting SEER to EER uses this formula: EER = −0.02 × SEER² + 1.12 × SEER [2] Note that this method is used for benchmark modeling only and is not appropriate for all climate conditions ...

    A realistic indication of energy efficiency over an entire year can be achieved by using seasonal COP or seasonal coefficient of performance (SCOP) for heat. Seasonal energy efficiency ratio (SEER) is mostly used for air conditioning. SCOP is a new methodology that gives a better indication of expected real-life performance, using COP can be ...
