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 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 (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 | \(dimensionless\) | \(dimensionless\) |
Seasonal Energy Efficiency Rating (EER below 14) Formula |
||
| \( SEER \;=\; \dfrac{ 1.12 - \sqrt{ 1.2544 - EER \cdot 0.08 } }{ 0.04 }\) | ||
| Symbol | English | Metric |
| \( SEER \) = Seasonal Energy Efficiency Rating (when EER is below 14) | \(dimensionless\) | \(dimensionless\) |
| \( EER \) = Energy Efficiency Rating | \(dimensionless\) | \(dimensionless\) |
