Many modern refrigerators today are equipped at the production stage with the Low Frost system. The old appliances have been replaced by improved and multifunctional models. It is easy to find a refrigerator for every taste in stores. Depending on financial possibilities and preferences, specialists will choose the most suitable option.
Many inexperienced users do not know what Low Frost in refrigerated cabinets is, and how the development differs from No Frost. Similar terms mean completely different technological modes of defrosting. Let’s try to find out what features each system has in order to choose the right refrigerator in the future.
Over time, a refrigerator that has served for many years, no matter how reliable, will want to be replaced with a new, beautiful unit that will fit harmoniously into the newly completed kitchen renovation.
Soviet-era refrigerators, inherited from grandparents, have to be defrosted often, but modern models are equipped with special features that prevent frost marks on the walls of the chamber for a long time.
In refrigerators with the Low Frost system, the evaporator is placed behind the walls of the freezing chamber and fills the free space around it.
The advantage of this technology is that the temperature changes inside the cabinet are minimized. As a result, there is no formation of an ice layer on the walls due to condensation, which cannot be said about the old classic models. The resulting cold air gradually coats the surface of the cabinet with a thin layer of ice, which is not noticeable at first glance.
Low Frost refrigerators have to be defrosted manually anyway. However, defrosting means regular wet cleaning of the chamber, which is recommended at least once every six months.
How to deal with ice in refrigeration units
To begin with, you can try to set the regulator or control panel to a plus temperature inside the cabinet, for example, as provided in the Free Frost system. Then gradually achieve cooling of the entire freezer volume. This process is performed automatically. As a result, a “weeping wall” effect is observed in the refrigerator.
This method cannot be called completely effective. Low Frost technology is considered to be the most advanced development in the field of household refrigerator appliance research. The device of a refrigerator equipped according to this principle generates cold according to the following scheme:
- There are no tubes in the evaporative appliance. The chamber is surrounded by double walls.
- Refrigerant is supplied and transferred through the evaporator. The chamber is cooled uniformly as the temperature decreases.
How Low Frost works in a refrigerator
The low Frost system applies only to a certain part of the cabinet – this is the cooling compartment. It has no effect on other compartments that are not intended for freezing.
If you examine the order of the technology in more detail, it is worth noting that the evaporator is outside the walls of the freezer compartment and completely covers the perimeter. When the cold is produced evenly, the formation of the ice crust is slowed down, because optimal conditions are created, under which the temperature drop is practically not felt.
The cold air is smoothly distributed on the walls and fills the space, creating a stable environment. As a consequence, there is no ice build-up. This feature allows you to defrost the refrigerator much less frequently. You can safely fill the shelves and drawers with the necessary products without fear of losing their freshness and formation of an ice crust.
Evaporator, which produces cold, is responsible for maintaining the microclimate in the general compartment. Food in the refrigerator does not spoil for a long time. The natural moisture creates favorable conditions for the storage of food products.
Pros and cons of the Low Frost system
The advantages of the Low Frost system include the following:
- The system is configured so that there is no risk of a sudden drop in temperature. Condensation hardly accumulates on the walls, so there is no danger of large ice build-up.
- Minimum air temperature difference between the chamber and the walls.
- Cooling affects the entire internal air of the freezer compartment, which causes condensation droplets to appear even on the surface of the food.
- The defrosting session in refrigerators that use this system is considered to be less time-consuming.
- The refrigerators with Low Frost have low costs in comparison with other models. The design is easy to use, reliable, and ergonomic and is designed for mass service of the population.
The disadvantages of Low Frost technology are the small amount of moisture that accumulates on the walls of the appliance. If the consumer wants to avoid defrosting at all, this refrigerator model is not suitable for him. Nevertheless, the technology deserves attention and is gaining popularity among middle-class consumers.
