According to data from Vietnam Electricity Corporation (EVN), a standard household refrigerator consumes between 50 to 75 kWh per month, making it one of the top three energy-consuming appliances in a home, following electric stoves and water heaters. Given that refrigerators run continuously throughout the year to maintain a stable temperature, their energy efficiency is directly influenced by external factors such as climate and seasonal changes.
During the summer, refrigerators have to work harder to keep food cool, as the surrounding environment is much warmer. However, in the winter, when ambient temperatures drop, refrigerators naturally require less energy to maintain their internal cooling levels. This is why adjusting the temperature settings on your refrigerator based on the season is a smart move—it optimizes energy usage, reduces strain on the appliance, and can significantly lower electricity bills.
Adjusting Your Refrigerator Temperature for Winter
Most modern refrigerators come with an adjustable temperature dial ranging from 1 to 5 or 1 to 6. During hot summer months, people tend to set the cooling level higher to ensure food stays fresh. However, in colder months, you can safely reduce the cooling intensity without affecting food preservation.
For optimal energy efficiency and food safety during winter, consider the following settings:
Fridge Compartment: Set it at level 1 or 2, maintaining a temperature between 35–41°F (2–5°C). This ensures perishable foods like dairy products, fruits, and vegetables remain fresh without overcooling.
Freezer Compartment: Keep it at approximately 0°F (-18°C) to ensure frozen foods, meats, and seafood remain at safe storage temperatures.
By lowering the cooling level in winter, the refrigerator compressor doesn’t have to work as hard, leading to reduced power consumption and noticeable savings on your electricity bill. However, your refrigerator’s cooling needs will also depend on how much food it stores:
Lightly stocked fridge: A lower cooling level is sufficient.
Heavily stocked fridge: More cooling power may be necessary to maintain consistent temperatures.
Additional Energy-Saving Tips for Your Refrigerator
Beyond adjusting the temperature settings, adopting a few smart habits can further enhance your refrigerator’s efficiency and extend its lifespan. Here are some best practices:
