1. What is COP to EER Conversion?

The COP (Coefficient of Performance) to EER (Energy Efficiency Ratio) conversion is used to compare the efficiency of cooling systems. While both measure efficiency, EER is more commonly used in the US for air conditioning systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( COP \) — Coefficient of Performance (dimensionless)
• \( 3.412 \) — Conversion factor (BTU/h per watt)
• \( EER \) — Energy Efficiency Ratio (BTU/h per W)

Explanation: The conversion factor 3.412 comes from the relationship between watts and BTU/h (1 watt = 3.412 BTU/h).

3. Importance of EER Calculation

Details: EER is important for comparing the energy efficiency of cooling devices under specific conditions. Higher EER values indicate more efficient systems.

4. Using the Calculator

Tips: Enter the COP value (must be greater than 0). The calculator will automatically compute the equivalent EER value.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between COP and EER?
A: Both measure efficiency but COP is a dimensionless ratio while EER has units of BTU/h per watt. EER is typically used for cooling systems.

Q2: What is a good EER rating?
A: Residential air conditioners typically range from 8-12. Higher values indicate better efficiency.

Q3: Can EER be converted back to COP?
A: Yes, by dividing EER by 3.412.

Q4: Why is 3.412 the conversion factor?
A: It comes from the relationship between watts and BTU/h (1 watt = 3.412 BTU/h).

Q5: Are there limitations to this conversion?
A: This is a straightforward mathematical conversion, but actual system performance may vary based on operating conditions.
