You've heard a lot about NoFrost technology integrated into home appliances, but is it worth paying extra for such a refrigerator? Before deciding, find out what this function is and what it does and what are the concrete advantages it offers you compared to standard models.
For those looking for a refrigerator, the No Frost label is already a familiar one, integrated quite visibly in the promotional materials, because it is an innovative technical feature, with many benefits. If you want to buy such a device and you do not know if it is worth it or not to spend money on a model of this type, first find out what it consists of and what this function can do for you.
What is No-Frost technology
NoFrost technology was launched in 1987, so it is not as new as we think, but it is much more efficient in today's models. From a technical point of view, this system uses an evaporator, a fan and a coil to manage the freezing of water vapor, inevitable in any refrigerator.
Water vapor inside the cooler is formed by releasing moisture from stored food and by penetrating hot air from the room when the door is used. The more often and longer the refrigerator is opened, the stronger the ice formation tendency will be. Exposed to cold air, moisture in the air condenses on the walls of the device and forms layers of ice, first thin, then thicker, which affects the operation of the device.
Unlike the standard options, the NoFrost or FreeFrost models circulate the air inside with the help of a fan, stimulating the accumulation of water vapor and their freezing at the evaporator. Once the system detects ice formation, a coil begins to melt, and water is removed through a pipe behind the refrigerator into a collection tray. In order not to affect the temperature inside too much, a thermal sensor stops this process when the level of 0 o C is reached.
In other words, the No Frost system ensures the freezing of steam outside the compartments used for storage, controlling its melting and disposal without you having to intervene.
NoFrost, TotalNoFrost, FreeFrost and Auto-Defrost
All are names that indicate that the refrigerator model you are evaluating does not require defrosting, because it includes a function that does this automatically and periodically. But there is an important difference between Total NoFrost or No Frost Freezer and the rest of the callsigns used.
The options with Total NoFrost and NoFrost Freezer also include a defrost system for the freezer compartment, while the rest of the variants make this technology available only for the refrigeration compartment.
If you have defrosted a refrigerator at least once, especially in winter, then you know how complicated it can be and that it will definitely take you at least half a day. First of all, you have to take all the food out of the drawers and on the shelves and find another cold storage place to prevent degradation. Then, you need to unplug the refrigerator and leave it with the door open, to melt the ice. This process can take between 2 and 5 hours, depending on how much ice has been deposited and how hot it is in the house.
And to make things even more complicated, you can't leave it unattended because most of the time the melted water drains on the floor, despite the towels and collection containers that you have strategically placed. After thawing, you must put all the food back in each compartment. An operation that consumes time and is not at all simple.
By comparison, a refrigerator with NoFrost technology does not accumulate ice on the walls, because the integrated system takes care of its periodic melting, so that it never accumulates enough to affect its operation. Everything happens every day, while you sleep, work, eat or drink your coffee, without even having to schedule it to do so. All you have to do is periodically empty the tray in which the condensed water is collected, resulting from the melting of the ice. It therefore means increased time and comfort for the whole family.
Studies show that a 2mm deposit of ice inside the refrigeration compartment can mean up to 10% more energy consumed by this appliance. If you are not willing to defrost it manually at least once a year, we recommend that you opt for a refrigerator with NoFrost technology.
Most of them are part of the energy efficiency category A + and above, which means that, although it will probably cost more than a classic version, you will definitely recover your investment from the insured current economy.
A variety of options
Because it is an efficient and appreciated technology, you can easily find models provided with this system in the offer of most of the brands that produce home appliances. You can choose a Samsung , Beko, Ariston, Heinner, Arctic, LG or any other recognized brand that you appreciate, because each of them has developed its own range of FrostFree models, although the names used for the technology vary.
Chilled food correctly and constantly
Ice deposited on interior walls affects food stored in two ways. First of all, everything that is positioned close to the area where the deposit takes place will freeze and you will wake up with food half frozen, in the compartment where you just want to keep it cold, so you can consume it quickly.
Secondly, these deposited layers affect the efficiency of the refrigerator and it may happen that during the summer, it fails to cool well enough and some more sensitive products break down.
The NoFrost function ensures a constant and uniform temperature, without freezing areas or too high a temperature on the top shelves. Your food is safe and you can safely buy large quantities of food, because they are kept in the best conditions, even on hot days.
