Many modern refrigerators are equipped with the Nou Frost system. The owners of such models may not be engaged in defrosting, because ice formations do not appear on the walls of the chambers. Let's take a look at the advantages and disadvantages of refrigerators with the No-Frost system.
Principle of operation
No-Frost is a cooling technology using circulating cold air. The air is evenly distributed throughout the refrigerator and freezer compartments, preventing temperature fluctuations. Such a system prevents the formation of ice: water vapor does not condense and does not freeze, therefore, frost does not form on the walls.
Refrigerator with No-Frost technology "Know Frost" does not need to be defrosted. Formally, frost appears, but this occurs in the case behind the back or side wall, or above the freezer - at the location of the evaporator, which is blown out using the fans located behind. They pump air through the ducts diverted into the chamber and ensure stable circulation.
Frost builds up on the evaporator rather than inside the compartments as in drip models. From time to time the compressor stops working, the heater turns on and removes the ice crystals. The moisture then flows down the grooves into the tank to quickly evaporate.
Despite all the advantages of the know-frost system, the device remains a refrigerator that needs to be periodically defrosting. It is worth disconnecting it from the network not only because of defrosting, but also before cleaning. If you have a Frost Free refrigerator model, then the container where the liquid is drained must be periodically cleaned.
Do not forget about the standard care: cleaning from dirt and dust from the inside and outside, using a damp cloth and gentle detergents.
80 percent of how home appliances work depends on the user and how he handles the device. Therefore, it is so important to comply with the operating conditions, and so that the advice from the manufacturer is not lost, we have collected the most important of them:
Do not defrost the know frost refrigerator by hand. Auto defrosting once a year will be enough.
The drip-type compartment is defrosting separately.
The device should be located away from walls, heat and direct sunlight.
All products are stored in packages and cling film.
The front and back of the refrigerator must be cleaned.
When cleaning the appliance, avoid chemicals with abrasive particles; there is enough soda and water to wash off the dirt.
Unplug the refrigerator when defrosting and cleaning.
No Frost refrigerators are a simplified brand of refrigerators of our time, but this does not negate their care. Observing the rules of operation, regularly cleaning the device, you extend its service life and save on repairs and replacement of parts.
