When the cooling system works efficiently, the compressor won't strain to chill your food. This ensures better food preservation and reduces energy consumption.
1. Tips to Keep Your Refrigerator Fresh and Energy-Efficient
Regularly Clean the Condenser Coils
The condenser coils, typically made of metal and located at the back of the fridge, play a crucial role in dissipating heat from the compressor. Therefore, make it a habit to clean the coils at least every 6 months (or once a year) to prevent dust buildup.
As a result, your fridge will run smoothly, and you'll save on energy costs.
When the cooling system operates efficiently, the compressor won't overwork to chill your food. This results in better food preservation, and the refrigerator will consume less electricity.

Seal Food Before Placing it in the Refrigerator
Before placing food in the refrigerator, use a food container or wrap it tightly. This helps the food retain freshness and moisture in the cold environment.
Moreover, the refrigerator compressor will work more efficiently to regulate the humidity inside the fridge. In essence, properly sealing food contributes to making the compressor work at a lower capacity, leading to the refrigerator using less energy.
Avoid Keeping the Refrigerator Door Open for Too Long
Frequent opening and closing of the refrigerator door causes the compressor to continuously adjust the temperature to maintain a certain level of cold and humidity inside the fridge.
Even a slight opening of the refrigerator door increases the temperature of the food inside, and the compressor has to operate to lower the temperature again.
Therefore, constant door opening and closing will make your home refrigerator consume more energy. Avoid keeping the refrigerator door open for too long to prevent energy wastage!

Keep the Refrigerator Moderately Full
This may sound strange! When you keep the refrigerator moderately full, you inadvertently create a temperature balance inside the fridge. This is because the cold items help cool each other.
Therefore, if your home refrigerator doesn't contain much food, you can place additional containers of ice or ice packs inside.
Ensure Optimal Temperature
Inside the refrigerator, if the temperature is too warm, the food will quickly lose its freshness. On the other hand, if the temperature is too cold, the food may spoil.
So, you need to maintain the right temperature to ensure the refrigerator uses energy efficiently.
Adjust the temperature appropriately for the refrigerator
Expert advice:
- Refrigerator compartment temperature: 37 °F – 40 °F (approximately 2 °C – 4 °C).
- Freezer compartment temperature: 5 °F (~-15 °C).
>> Handy Tips to Determine Refrigerator Temperatures:
- For the refrigerated section: Place a thermometer in a glass of water in the center of the fridge, and check after 24 hours.
- For the freezer section: Place a thermometer among frozen foods, and check after 24 hours.
Use a Compact Refrigerator for Small Families
With a larger refrigerator capacity, more refrigerant is required to cool the entire space inside the fridge. Therefore, the energy consumption of the refrigerator will be higher.
For instance, small families (2 people) or newlyweds don't need to buy a refrigerator with a capacity of 300 liters. Instead, they can opt for a refrigerator with a capacity of approximately 90 – 150 liters.
Choose a Refrigerator Capacity that Suits Your Needs
Regularly Check the Door Gasket
The refrigerator door – the inner side, is often equipped with a gasket lining to prevent the leakage of temperature from inside to outside when closed.
If the gasket is bent or torn, the cold air (inside the fridge) will escape outside. Simultaneously, the room-temperature air (outside the fridge) can easily seep into the fridge. Consequently, the refrigerator will have to use more energy to regulate the temperature again.
Therefore, when you notice an issue with the door gasket, promptly replace them!

Avoid Putting Hot Food in the Refrigerator
You inadvertently place hot food, even a pot of freshly cooked stew, inside the fridge right after cooking. All the heat from the food will dissipate, warming the air inside the refrigerator.
At that point, the refrigerator's compressor will have to use more energy, operating more to cool the air inside the fridge. In this way, it's challenging to save energy when using the refrigerator.

Regularly Defrost the Freezer Compartment (For Frost-Free Refrigerators)
If the freezer compartment of the refrigerator doesn't have an automatic defrost feature, then you need to regularly defrost it.
Note: Don't let the frost layer exceed 0.5 cm, as it will impede the airflow in the ice compartment and retain the moisture of the food.
By minimizing the lingering moisture of food inside the refrigerator, you will save a significant amount of energy. Moist air requires more energy for quick cooling.
Regularly defrosting the refrigerator also helps save energy
Turn off the Automatic Ice Maker Feature
If the automatic ice maker feature is enabled, the refrigerator will consume more energy. Therefore, turn off this feature when not in use or when there is already plenty of ice in the bin.

Keep Away from Heat Sources
Try to avoid placing your refrigerator near the oven or other heat-emitting devices, especially under direct sunlight. Because these factors will warm up your home refrigerator, particularly affecting the efficient operation of the compressor.
Position the Refrigerator Away from Heat-Emitting Devices and Sunlight
