The SEER (Seasonal Energy Efficiency Ratio) is an efficiency index that considers temperature and demand variations throughout a typical cooling season.
Difference between EER and SEER
| Feature | EER | SEER |
|---|---|---|
| Test condition | Single (35°C) | Multiple temperatures |
| Load | 100% | Variable |
| Representativeness | Low | High |
| Use | Quick comparison | Real operating cost |
