Seasonal Energy Efficiency Rating
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 Btu of cooling
- seasonal watt-hours used
Seasonal Energy Efficiency Rating (Varying Weather Conditions) formula |
||
\( SEER \;=\; 1 \; ( EER \; 100\% ) + 42 \; ( EER \; 75\% ) + 12\; ( EER\;250\%\ ) \;/\;100 \) | ||
Symbol | English | Metric |
\( SEER \) = Seasonal Energy Efficiency Rating (varying weather conditions) | \(dimensionless\) | \(dimensionless\) |
\( EER \) = Energy Efficiency Rating | \(dimensionless\) | \(dimensionless\) |
Seasonal Energy Efficiency Rating (EER above 14) formula |
||
\( SEER \;=\; EER \;/\; 0.875 \) (Seasonal Energy Efficiency Rating (EER above 14)) \( EER \;=\; SEER \; 0.875 \) |
||
Symbol | English | Metric |
\( SEER \) = Seasonal Energy Efficiency Rating (when EER is above 14) | \(dimensionless\) | \(dimensionless\) |
\( EER \) = Energy Efficiency Rating | \(dimensionless\) | \(dimensionless\) |
Seasonal Energy Efficiency Rating (EER below 14) formula |
||
\( SEER \;=\; 1.12 - \sqrt{ 1.2544 - EER \; 0.08 } \;/\; 0.04 \) | ||
Symbol | English | Metric |
\( SEER \) = Seasonal Energy Efficiency Rating (when EER is below 14) | \(dimensionless\) | \(dimensionless\) |
\( EER \) = Energy Efficiency Rating | \(dimensionless\) | \(dimensionless\) |
