Nowadays, refrigerators are not only used during hot summer days but operate 24/7, even in winter, to preserve fresh food and enhance longevity and quality...
1. Placing a water bowl inside the fridge works wonders, surprising users with its effectiveness
This method has numerous advantages as it relies on the cooling principle of the refrigerator.
Refrigerators are no longer exclusive to summer or scorching days; they are now used around the clock for preserving fresh produce and improving overall food quality. However, this practice can lead to higher electricity bills each month.
There are many simple ways to save electricity for your refrigerator that anyone can implement. One such method is placing a bowl of water inside the fridge. So, how is this done, and what purpose does it serve that many moms swear by? The answer will leave you surprised!

Execution Method
- Before bedtime, take a bowl (or tray, box, bottle,... anything works) and place it in the freezer compartment of the fridge (preferably at night).
Place a water bowl in the freezer compartment of the fridge before going to bed.
- The next morning, after waking up, take the frozen water bowl out and leave it in the chilled compartment of the fridge.
- Repeat this procedure daily.
The purpose of placing a water bowl in the fridge
This method holds numerous advantages as it leverages the refrigeration cooling principle. During the night, when the fridge opens and closes less frequently (consuming less energy than during the day), the water bowl placed in the freezer compartment cools down faster.
As the frozen water bowl is placed in the chilled compartment, it gradually melts and defrosts until it reaches room temperature. This defrosting process provides the refrigerator with cool air (without relying on electricity), ensuring minimal power consumption.

The frozen water bowl, as it thaws, contributes cool air to the refrigerator without consuming electricity.
Moreover, this water bowl helps keep fruits and vegetables fresh for a longer time, reducing water loss, preventing quick wilting, and maintaining optimal storage duration.
With such beneficial uses, it's easy to implement. There's no reason not to try it tonight before going to bed!
Note when using the refrigerator to maximize electricity savings
- Limit the frequency of opening and closing the refrigerator door, or keeping it open for too long: This causes a loss of cold air inside the fridge, making it work harder to cool down, resulting in higher electricity consumption. It also makes food preservation challenging and increases the risk of damaging the rubber seal due to frequent impact.
- Avoid keeping the refrigerator too empty or too full: Even when there is no food, the refrigerator continues to run, leading to unnecessary power wastage. Overpacking the fridge causes continuous operation, uneven distribution of cold air, resulting in losses and reducing the system's lifespan.

Keeping the refrigerator about 70-80% full helps it run efficiently and save energy. Additionally, avoid storing hot food in the fridge as it consumes more electricity and imparts odors into the refrigerator.
- Avoid placing the refrigerator against the wall, keep it away from heat sources: Leave a certain space on both sides, the back, and around the fridge for easy air circulation, enhancing the efficiency of heat dissipation from the condenser.
- Regularly check the freezer compartment to promptly address frost and ice buildup, as a faulty ice discharge part in the cooling unit can lead to energy wastage.
- Regularly clean and maintain the hygiene of the refrigerator, especially the door seal, to prevent leaks of cold air. If any malfunction is detected, promptly report it to a repair technician or a reputable refrigerator repair center for thorough inspection.
