Frost Free

What execatly is a frost free fridge freezer.

The mechanism on a refrigerator involves letting the cooling element heat up for a short period, melting any ice that has formed upon it and having it drain through a collecting duct at the back of the unit.

Inside the freezer, dry air is circulated around the cabinet using fans (this is why such kind of appliances are also called "dynamic", whereas non frost free fridge freezers are called "static"). Instead of the traditional cooling elements assembled within all the freezer liner, those of a frost-free system are compact and separated from the main cabinet space, allowing them to be heated for short periods to dispose of any ice forming.

While this technique was originally and is mostly applied to freezer compartments, it can also be used for fridge compartments. A combined fridge freezer which applies the frost free system to the freezer compartment only is usually called "partial frost free", while one which also applies it to the fridge compartment is called "total frost free". The latter features an air connection between the two compartments, with the air passage to the fridge compartment regulated by a dumper. In such a way, a controlled minor part of the dry and fresh air coming from the dynamic cooling element located within the freezer can reach the refrigerator.

Some newer fridge freezer models have built-in electronics that monitor how many times each door is opened and could also average the door open time which will automatically adjust defrost scheduling, therefore optimizing power dissipation.

What Exactly Is Frost Free

Frost Free - choose a Frost Free fridge freezer and you will never have to worry about defrosting your freezer again.

Advantages of frost free
No need to manually defrost the ice buildup
Food packaging is easier to see because it's clear of frost
Most frozen foods don't stick together
Smells are limited, especially in total frost free appliances, since the air is constantly circulating

Disadvantages of frost free
The system is more expensive to run due to higher power consumption
A safety device is required to be connected with the heating element, due to the high instant-power values that can be reached
The temperature of the freezer contents rises during the defrosting cycles
On hot humid days condensation will sometimes form around the refrigerator doors
