SEER Calculation Formula:
| From: | To: |
SEER (Seasonal Energy Efficiency Ratio) and EER (Energy Efficiency Ratio) are measures of air conditioning efficiency. SEER represents seasonal average efficiency while EER measures efficiency at a specific temperature (usually 95°F).
The calculator uses the approximation formula:
Where:
Explanation: This formula approximates SEER from EER by accounting for seasonal variations in efficiency performance.
Details: Understanding the relationship between SEER and EER helps in comparing air conditioning efficiency ratings and making informed purchasing decisions for energy-efficient cooling systems.
Tips: Enter EER value in BTU/Wh. The value must be greater than 0. The calculator will provide the approximate SEER value based on the standard conversion factor.
Q1: Why is there a conversion factor between SEER and EER?
A: SEER accounts for seasonal variations and part-load operation, while EER measures efficiency at peak conditions, requiring a conversion factor for comparison.
Q2: How accurate is the 0.875 conversion factor?
A: This is an approximation. Actual conversion may vary slightly depending on specific equipment and operating conditions.
Q3: What are typical SEER and EER values?
A: Modern air conditioners typically have SEER ratings from 14-25 and EER ratings from 11.5-14. Higher values indicate better efficiency.
Q4: When should I use SEER vs EER?
A: Use SEER for overall seasonal efficiency comparison and EER for peak cooling performance assessment in hot climates.
Q5: Are there limitations to this conversion?
A: This is an approximation and may not be precise for all equipment types or under all operating conditions.
