The Energy Efficiency Ratio (EER) is calculated by dividing the cooling output in BTU (British Thermal Units) by the power input in watts. This provides a measure of how efficiently an air conditioner cools a space using a certain amount of electricity.
Understanding EER
EER, or Energy Efficiency Ratio, is a rating that helps consumers understand the efficiency of cooling appliances, specifically air conditioners. A higher EER indicates greater energy efficiency.
EER Calculation
Here's how to calculate the EER:
- Formula: EER = BTU / Watts
Example:
According to provided context, a 12,000-BTU air conditioner that uses 1,200 watts has an EER rating of 10 (12,000/1,200 = 10).
- BTU (British Thermal Units): This measures the cooling capacity of the air conditioner. It indicates the amount of heat the unit can remove from a room per hour.
- Watts: This measures the electrical power consumed by the air conditioner.
| Metric | Description |
|---|---|
| BTU (British Thermal Unit) | Measures cooling output (amount of heat removed per hour). |
| Watts | Measures power consumption (electrical power used by the unit). |
| EER | Energy Efficiency Ratio (BTU/Watts) |
Benefits of Knowing EER
Understanding and comparing EER values helps you:
- Choose more energy-efficient air conditioners.
- Reduce energy consumption and lower electricity bills.
- Make informed purchasing decisions.
In summary, the EER is a straightforward calculation that provides valuable insight into the energy efficiency of air conditioning units, helping you make smart choices for your cooling needs.
