Start by choosing the right balance of usable space for fresh food and frozen portions, then check that your containers can be stored without disrupting air circulation. A fridge freezer is ideal for regular use of both compartments in a single location; separate appliances may be more suitable for a consistently large frozen-food stock if you have enough space.
To store several portions for the days ahead, prioritise shelves, drawers and usable capacity that can accommodate containers without blocking airflow. Anses recommends monitoring the temperature, reserving the coldest area for perishable cooked dishes and avoiding overloading the appliance.
If prepared meals, bulk purchases or family-sized portions remain in the freezer for extended periods, compare its usable capacity separately from that of the fridge. The choice between a fridge freezer and two separate appliances mainly depends on the actual size of your stock and the space available.
In a recess or small kitchen, check the installation dimensions, overall dimensions, door-opening direction, net capacity and freezer-compartment layout before choosing a compact model.
Start with the amount you normally store, then compare the internal layout, temperature control and energy label across appliances of a similar size.
| Priority | What to check | Your needs |
|---|---|---|
| Temperature and storage | Temperature adjustment and display; door or temperature alarm, if available; location of the coldest area and space between containers. | I want to be able to place meat, fish and perishable cooked dishes in the coldest area. Anses recommends monitoring a temperature of 4 °C there and not overloading the appliance. |
| Fresh-to-frozen capacity | Fridge and freezer usable capacities shown separately; drawers, adjustable shelves and large bins; fast-freeze function if it suits the amount you are loading. | My meal boxes and frozen portions need to fit at the same time. I therefore compare both capacities rather than relying on the total capacity alone. |
| Ongoing energy use | Energy class from A to G, annual consumption in kWh, usable capacities and noise level. Compare models with similar configurations and capacities. | I am looking for an appliance sized to my actual stock, without paying to power capacity I do not need. ADEME points out that fridges and freezers run continuously, and that both size and unnecessary features can increase consumption. |
| Maintenance and frost | Cooling technology specified for each compartment; defrosting requirements; condition of the door seal and any open-door alarm. | I want to reduce defrosting, while keeping a layout that suits my needs. A No Frost function can help depending on the model, but it does not replace temperature checks or sensible loading. |
Two appliances with a similar total capacity can offer very different splits between refrigeration and freezing. For example, Bosch lists 260 l of fridge capacity and 103 l of freezer capacity for the KGN39AIAU, while Whirlpool lists 182 l and 68 l for the WHC18T132FR.
List your meal containers, your usual frozen-food stock and the fresh food you keep at the same time. Then compare both usable capacities, along with the drawers and shelves that can genuinely be used.
Anses recommends avoiding overloading so that air can circulate. A large stated capacity therefore does not remove the need to organise your boxes and reserve the coldest area for perishable foods.
Choose a layout that leaves space between containers, and check the temperature in the coldest area after loading the appliance heavily.
These functions can make defrosting, airflow or notification of an open door easier, but they do not replace correct storage and temperature practices. Anses continues to stress the need to monitor temperature and avoid overloading.
Think of these functions as useful aids. Check which compartment they apply to and plan temperature checks that are compatible with the instructions and your storage habits.
Cooling appliances run continuously. ADEME states that size and unnecessary features can increase consumption, so unnecessarily large capacity may cost more to run.
Size the appliance according to the stock you actually keep, and compare kWh/year, energy class, capacities and noise level between models of the same size.
The range includes freestanding fridge freezers, built-in one-door models with a freezer compartment, and features such as Total NoFrost, Multi Airflow and alarms, depending on the model.
Liebherr offers fridges, fridge freezers and separate freezers, with many NoFrost, EasyFresh and DuoCooling models to compare when fresh and frozen stocks change independently.
The range includes built-in and freestanding fridge freezers, models designed for kitchens with a dedicated recess, and appliances offering Total No Frost, temperature controls and fast freezing.
The built-in fridge-freezer range covers static-cooling and Low Frost models, with door and temperature alarms on selected references.
These Joybuy options are fridge freezers designed to store fresh food, prepared meals and frozen portions together.

For households with enough space and a substantial fresh and frozen-food stock.
Offers a stated 311 l of fridge capacity and 156 l of freezer capacity, with separate temperature controls, two freezer drawers, Total No Frost and an audible open-door alarm.
At 83.3 cm wide, with non-reversible doors: check the location, clearance and opening direction.

A fridge freezer for regularly organising fresh and frozen portions in a standard kitchen.
Offers a stated 235 l of fridge capacity and 125 l of freezer capacity, with three freezer drawers, Super Freezing, external electronic controls and Total No Frost.
Check that this split matches the actual volume of containers and portions you store at the same time.
Image unavailable
A built-in option for a fitted kitchen that needs separate fresh and frozen-food compartments.
Offers a stated 176 l of fridge capacity and 76 l of freezer capacity, with three drawers, digital display, door and high-freezer-temperature alarms, No Frost and Multi Air Flow.
Check the recess, mounting and ventilation compatibility; 76 l of freezer capacity may be limiting for a consistently large stock.
Image unavailable
For households that need a large fresh-food capacity while regularly freezing portions.
Offers a stated 311 l of fridge capacity and 129 l of freezer capacity, with five shelves, a meat and fish zone, Multi Airflow and a fast-freeze function.
The stated dimensions of 70 × 203 × 66.7 cm mean you should check access, flooring, ventilation and handling; the freezer compartment’s exact maintenance requirements should also be confirmed.
Image unavailable
A freestanding fridge freezer for a medium to large household that prepares meals in advance.
Offers approximately 249 l of fridge capacity and 106 l of freezer capacity, with Total No Frost, separate controls, a four-star compartment, C energy class, 240 kWh/year and 35 dB.
Check the exact capacities in the final product details, along with the clearance and access required for its dimensions of 210.2 × 76.2 × 66.1 cm.
Anses recommends monitoring 4 °C in the coldest area of the fridge, referring to the manufacturer’s instructions. Place meat, fish and perishable cooked dishes there, and check the actual temperature rather than relying solely on the figure shown on the display.
No. According to Anses, domestic freezing at -18 °C stops bacterial growth, but most microorganisms survive freezing. Freeze food as soon as you buy or prepare it, defrost it in the fridge, in the microwave using the defrost setting or quickly by cooking, and never refreeze food that has already been defrosted.
No Frost can reduce or eliminate the need for defrosting depending on the compartment and model, but it is not, by itself, a guarantee of food safety. Keep usable capacity, sensible loading, temperature control and the placement of perishable food in the coldest area as your key criteria.
The European energy label for domestic fridges and freezers uses a scale from A to G. The European Commission states that it shows, among other details, annual consumption in kWh, the capacities of the fresh and frozen-food compartments, as well as noise emissions and their class.
