Using a bowl of water is a simple but efficient approach to reduce your refrigerator’s electricity use. Here are a few suggestions on how you might make use of this idea:
1. Increase Humidity in the Refrigerator
How it Works: The bowl of water contributes to a slightly greater humidity level within the refrigerator. When the air is more humid, fruits and vegetables are less likely to dry out, reducing the need to replace food that wilts or shrivels too rapidly.
Savings: By throwing away less spoiled food, you can reduce food waste and, as a result, cut your shopping bill. It can also help keep your fridge running more efficiently by requiring less electricity to maintain the appropriate temperature and moisture level for your food.
2. Prevent Overworking Your Fridge’s Compressor
How It Works: Adding a bowl of water makes the refrigerator’s compressor function more effectively. A regular internal humidity level keeps the fridge from having to work too hard to keep the internal climate stable. Without enough moisture, fridges may have to cycle more frequently, using more electricity.
Savings: By lowering the amount of cycles your fridge must go through, you can save on power. When the refrigerator does not have to work extra to compensate for extreme temperature or humidity fluctuations, it consumes less electricity.
3. Improved Temperature Stability
How It Works: A bowl of water can assist in maintaining the temperature inside the refrigerator. Water has a high heat capacity, which means it can absorb and hold more heat than air. This is especially useful when you often open the fridge door, as it reduces temperature swings caused by warm air entering.
Savings: With a more consistent interior temperature, the fridge does not have to work as hard to cool down once you open the door. This decreases energy consumption while keeping your appliance working smoothly.
4. Use the Right Bowl
How It Works: The bowl should be shallow and wide, not deep. This provides more surface area for water to evaporate slowly, resulting in a higher degree of humidity in the fridge. You can also use a ceramic or stone bowl, which retains moisture better and releases it more slowly.
Savings: A properly placed bowl of water (not overfilled) can provide the desired humidity levels without wasting any water. It’s a small, low-cost investment that might save you money on your electricity bill while also reducing food waste.
Other Considerations
Don’t Overcrowd Your Fridge
A crowded refrigerator is less efficient. It is critical to leave enough room around the bowl of water for air to circulate freely.
Use A Refrigerator Thermometer
Make sure your refrigerator is set to the proper temperature. A refrigerator’s optimal temperature ranges from 35°F (1.6°C) to 38°F (3.3°C). This is the best range for keeping food fresh while conserving energy.
Avoid Overloading the Freezer
Overloading the freezer can make it difficult for the fridge to keep a consistent temperature, resulting in increased energy use.
