Understanding the cost implications of your refrigerator’s amp draw can influence purchasing decisions, energy conservation practices, and overall spending on utilities.
Calculating Monthly Cost
To determine the monthly cost associated with your refrigerator’s energy consumption, use the following formula:
Monthly Cost = Daily Energy Consumption × 30 × Cost per kWh
Assuming a cost of $0.12 per kWh, the example calculation from earlier would yield:
Monthly Cost = 17.28 kWh × 30 × $0.12 = $62.12
Tips for Reducing Amp Draw and Energy Consumption
Although you may not be able to change the size or model of your refrigerator instantly, there are several strategies to help reduce amp draw and energy consumption.
Regular Maintenance
Keep your refrigerator clean, especially the coils, which can accumulate dust and debris. Regular maintenance ensures optimal performance, potentially reducing amp draw.
Temperature Settings
Set your refrigerator temperature to a reasonable setting. The USDA recommends a refrigerator temperature of 37°F and a freezer temperature of 0°F. Overcooling can lead to unnecessary energy consumption.
