SEER2 to SEER Conversion Formula:
| From: | To: |
The SEER2 to SEER conversion formula provides an approximate method to convert the new SEER2 efficiency rating to the traditional SEER rating. This helps in comparing new systems with older efficiency standards and understanding performance across different rating systems.
The calculator uses the conversion formula:
Where:
Explanation: The new SEER2 standard uses different testing conditions that typically result in slightly lower ratings compared to the traditional SEER system for the same equipment.
Details: Understanding the conversion between SEER2 and SEER ratings is crucial for comparing HVAC system efficiencies, making informed purchasing decisions, and ensuring compliance with energy efficiency standards across different rating systems.
Tips: Enter the SEER2 rating in BTU/Wh. The calculator will provide the approximate equivalent SEER rating. All values must be valid positive numbers.
Q1: Why was SEER2 introduced?
A: SEER2 was introduced to provide more accurate efficiency ratings that better reflect real-world operating conditions with updated testing procedures.
Q2: Is the conversion exact?
A: No, this is an approximate conversion. Actual conversion may vary slightly depending on specific equipment and testing conditions.
Q3: When should I use this conversion?
A: Use this conversion when comparing new SEER2 rated equipment with older SEER rated systems or when working with specifications that use different rating standards.
Q4: Are there limitations to this conversion?
A: This conversion provides a general approximation and may not be accurate for all equipment types or under all operating conditions.
Q5: What's the difference in testing between SEER and SEER2?
A: SEER2 uses updated testing conditions that include different external static pressure requirements, providing a more realistic representation of actual system performance.
