Calculate Fridge Energy Consumption

How to Use This Calculator

To calculate your fridge's energy consumption:

1. Enter your fridge's energy efficiency rating (EER) in BTU/h
2. Select the type of fridge (top-freezer, bottom-freezer, or side-by-side)
3. Enter the number of hours your fridge is used per day
4. Click "Calculate" to see your estimated annual energy consumption

The calculator uses standard assumptions about electricity costs and usage patterns. For more accurate results, you may need to adjust these values based on your specific situation.

Formula Used

The energy consumption is calculated using the following formula:

Where:

• EER = Energy Efficiency Rating in BTU/h
• Hours Used Per Day = Average daily usage in hours
• 365 = Number of days in a year
• 1000 = Conversion factor from BTU to kWh

This formula provides an estimate based on standard assumptions. Actual consumption may vary based on factors like temperature, usage patterns, and specific model characteristics.

Worked Example

Let's calculate the annual energy consumption for a fridge with:

• Energy Efficiency Rating (EER): 150 BTU/h
• Type: Top-freezer
• Hours used per day: 24

This means the fridge would consume approximately 1,314 kilowatt-hours of electricity in a year.

Interpreting Results

The calculator provides several key pieces of information:

1. Annual Energy Consumption: Total electricity used in a year
2. Estimated Annual Cost: Based on average electricity rates
3. Energy Efficiency Rating: Your fridge's efficiency classification

To reduce your fridge's energy consumption:

• Set the temperature to 37°F (3°C) or lower
• Keep the door closed as much as possible
• Clean the condenser coils regularly
• Consider upgrading to a more energy-efficient model
