1. What is Energy Efficiency Rating (EER)?

Energy Efficiency Rating (EER) is a measure of how efficiently a cooling system operates. It represents the ratio of cooling capacity (in BTU/h) to power input (in watts). Higher EER values indicate more energy-efficient systems.

2. How Does the Calculator Work?

The calculator uses the EER equation:

\[ EER = \frac{Cooling\ Capacity\ (BTU/h)}{Power\ Input\ (W)} \]

Where:

\( Cooling\ Capacity \) — The cooling power of the system in British Thermal Units per hour (BTU/h)
\( Power\ Input \) — The electrical power consumption in watts (W)

Explanation: The equation calculates how many BTUs of cooling are produced per watt of electrical energy consumed.

3. Importance of EER Calculation

Details: EER is crucial for evaluating energy efficiency of air conditioning and refrigeration systems. It helps consumers choose more efficient appliances, reduces energy costs, and minimizes environmental impact.

4. Using the Calculator

Tips: Enter cooling capacity in BTU/h and power input in watts. Both values must be positive numbers. The calculator will compute the Energy Efficiency Rating.

5. Frequently Asked Questions (FAQ)

Q1: What is a good EER rating?
A: Generally, EER values above 10 are considered good, with higher values indicating better efficiency. The minimum EER requirements vary by region and equipment type.

Q2: How does EER differ from SEER?
A: EER measures efficiency at a specific operating condition, while SEER (Seasonal Energy Efficiency Ratio) measures average efficiency over an entire cooling season.

Q3: Why is EER important in the Philippines?
A: In tropical climates like the Philippines with high cooling demands, energy-efficient systems with high EER ratings can significantly reduce electricity costs.

Q4: Can EER be used for all cooling systems?
A: EER is primarily used for room air conditioners and smaller cooling systems. Larger systems may use different efficiency metrics.

Q5: How can I improve my system's EER?
A: Regular maintenance, proper sizing, clean filters, and upgrading to more efficient equipment can improve EER performance.
