In general terms, it would be more economical to empty your fridge-freezer when going on holiday for a couple of months in the summer rather than leaving it packed. Here's why:
Energy consumption: When the fridge-freezer is fully stocked, it retains coldness more effectively because the mass of the food helps to maintain lower temperatures. However, when the unit is empty, it takes less energy to maintain a lower temperature since there is less thermal mass to cool. Therefore, an empty fridge-freezer will consume less energy during your absence, resulting in lower electricity costs.
Potential malfunctions: Even with a modern and efficient fridge-freezer, there is still a chance of malfunctions or technical issues occurring over an extended period. If you leave your fridge-freezer packed with perishable food, a malfunction could lead to spoilage and the loss of the entire contents. By emptying the unit, you eliminate the risk of food waste and potential damage to the appliance caused by prolonged exposure to an unforeseen issue.
Food spoilage: If you leave perishable food items in your fridge-freezer for a couple of months without proper temperature control, there is a high likelihood of spoilage. This can result in food waste and an unpleasant odor in the unit. Emptying the fridge-freezer and properly disposing of perishable items before your trip will prevent such issues.
However, it's important to note that there are a few considerations to keep in mind:
Non-perishable items: If you have non-perishable food items that are unopened and unlikely to spoil during your absence, such as canned goods or non-refrigerated pantry items, you can leave them in the fridge-freezer without major concerns. These items won't contribute significantly to energy consumption.
Freezer settings: If you decide to empty the fridge-freezer, ensure that you adjust the settings accordingly. You can set the refrigerator compartment to a warmer temperature, closer to room temperature, to conserve energy while keeping it fresh. The freezer can be set to its lowest temperature to prevent any frost or ice buildup during your absence.
Cleaning: Before leaving, thoroughly clean your fridge-freezer, removing any spills or food residue. This will help maintain a hygienic environment and prevent unpleasant odors when you return.
By considering these factors and assessing the contents of your fridge-freezer, you can make an informed decision about whether to empty it or leave it packed during an extended absence. Remember to consult the manufacturer's guidelines and recommendations specific to your appliance model for the best practices when leaving it unattended for an extended period.
