The size of refrigerator is a choice of your lifestyle. However you can reduce your carbon emissions by choosing the right one. The general rule of thumb is shown in the table on the right:
|Family size||Capacity of the fridge* (Litre)|
|Two-member||Between 200 to 230|
|Every additional member||+25|
|* It shows the fridge capacity only. Freezer space should be added on top of that.|
1. A packed refrigerator will block the interior air circulation thus lower the efficiency and spoil the food. However, an empty refrigerator will need more power to cool its interior than a full one because an appropriate amount of fillings will help trap coolness. You can simply keep jugs with water in your fridge if it is always empty.
2. Keep all food and liquid covered. Uncovered food and drink add moisture to the air, and more energy is consumed to cool the interior.
3. It takes more power to cool the interior of the refrigerator when heated things are put inside. It is recommended that food should be cooled down before being put into the refrigerator.
4. It is most efficient to run the fridge section of a refrigerator at a constant 3°C. Every degree cooler will increase the energy consumption by 5%.
5. When placing your refrigerator, leave some room for ventilation.
