Seasonal Energy Efficiency Rating

 

Seasonal Energy Efficiency Rating (Varying Weather Conditions) Formula
\( SEER \;=\; \dfrac{ 1 \cdot ( EER \cdot 100\% ) + 42 \cdot ( EER \cdot 75\% ) + 12\cdot ( EER \cdot 250\%\ ) }{100 }\) 
Symbol English Metric
\( SEER \) = Seasonal Energy Efficiency Rating (varying weather conditions) \(dimensionless\) \(dimensionless\)
\( EER \) = Energy Efficiency Rating \(dimensionless\) \(dimensionless\)

Seasonal energy efficiency rating, abbreviated as SEER, also called seasonal energy efficiency ratio, a dimensionless number, measure the efficiency a residental central cooling will operate over an entire cooling season.

Seasonal Energy Efficiency Rating (EER above 14) Formula

\( SEER \;=\; \dfrac{ EER }{ 0.875 }\)     (Seasonal Energy Efficiency Rating (EER above 14))

\( EER \;=\; SEER \cdot 0.875 \)
Symbol English Metric
\( SEER \) = Seasonal Energy Efficiency Rating (when EER is above 14) \(dimensionless\) \(dimensionless\)
\( EER \) = Energy Efficiency Rating \(dimensionless\) \(dimensionless\)
