1. What Is EER?

Energy Efficiency Ratio (EER) is a measure of how efficiently an air conditioning system operates. It represents the ratio of cooling capacity (in BTU/h) to power input (in watts) under specific test conditions.

2. How Does The Calculator Work?

The calculator uses the EER equation:

Where:

• \( Cooling\ Capacity \) — The amount of heat the AC can remove (BTU/h)
• \( Power \) — Electrical power consumed by the AC unit (W)

Explanation: Higher EER values indicate more efficient air conditioning systems that provide more cooling per unit of electricity consumed.

3. Importance Of EER Calculation

Details: EER is crucial for comparing energy efficiency of different AC units, estimating operating costs, and making informed purchasing decisions for energy-efficient cooling solutions.

4. Using The Calculator

Tips: Enter cooling capacity in BTU/h and power consumption in watts. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What Is A Good EER Rating?
A: EER ratings typically range from 8 to 12. Higher values indicate better efficiency. Units with EER above 10 are considered energy efficient.

Q2: How Does EER Differ From SEER?
A: EER measures efficiency at a specific outdoor temperature (95°F), while SEER (Seasonal Energy Efficiency Ratio) measures efficiency over an entire cooling season.

Q3: Why Is EER Important For AC Selection?
A: Higher EER units consume less electricity for the same cooling output, resulting in lower energy bills and reduced environmental impact.

Q4: What Factors Affect EER?
A: Compressor efficiency, heat exchanger design, fan motor efficiency, and overall system design all impact the EER rating.

Q5: Is Higher EER Always Better?
A: While higher EER indicates better efficiency, higher-rated units typically cost more. The optimal choice depends on climate, usage patterns, and budget.
