REFRIGERATOR NO FROST
The term does not frost comes from the English and refers to refrigerators that "do not frost" and put it in quotes because it is not quite true. It is based on a simple trick but it requires that we understand that it is a heat engine. In an internal combustion engine (or heat engine) takes advantage of the heat transfer from a point with a very high temperature, called "hot source" to one that is cooler and is called "heat sink" to work. A simple diagram explains: hot spotlight>> Motor>> Focus cold. So does a car engine, the hot is on the pistons (which heats up when the fuel explodes), the engine is the set of mechanisms to leverage the expanding gases to move the car and the cold is the radiator. A refrigerator is a heat engine is something peculiar, carries heat from the cold to the warm, which is not spontaneous, then the engine does work on the expanding gases, something like this: the cold>> Motor>> Focus hot. In refrigerators common air entering the refrigerator (the coldest part of refrigerator) moisture deposited on the walls of it and ended up freezing, as more air entering the refrigerator when you open more moisture it was entered and more ice . The remedy is simple, every so often "turned off" the refrigerator and let thaw (if you try to manually remove the ice can damage the channels through which the gas travels cold). The first solution found was simple, the engine could reverse the flow of heat so that for a few minutes a day the fridge was warm and the ice melted. The problem encountered is that no one could "calibrate" the process so simple and the energy consumption of these devices increased (remember that in and of themselves a lot of energy the refrigerator). The final solution was something simple and nothing new is put a system similar to the "air handling units" (UTA). The air is taken and passed through a condensing plate (similar to the radiator of a car but of metal) and once cold leads to the fridge. The purpose of this board is not only cool, even in the refrigerator "no frost" the water is deposited there, not in the fridge, removing frost and water is collected in a small container that is near the engine and ends evaporating. Greatly reduced power consumption with a small flaw: the water can freeze on the board of condensation. This is sometimes the weather conditions, damage to the insulators or leave the door open too long. The remedy is simple: let it thaw, check the gaskets for to be changed, lock the door

REFRIGERATOR THAT MEANS THAT IS A "NO FROST"? A refrigerator is NO FROST when you delete the icing in the freezer because it uses a permanent ventilation to prevent the same occurrence, removing internal moisture.
What other things should I consider? BE TROPICAL Make sure the refrigerator is of tropical type or at least subtropical. This is the ability of insulation that has the refrigerator with respect to the external temperature has no direct relationship with the stars. The tropical refrigerator should be indicated with the letter "T" shape, the product or the nameplate. This means that withstand temperatures up to 43 ° C without losing the values of normal internal cold. The fridge is subtropical ST order code, and achieves the same efficiency of cold ambient temperature to 35 ° C. The fridge is indicated for mild climate with the letter N and supports up to 32 ° C with normal functioning. The above them to work in temperatures that support will shorten its life.

THE STARS The stars indicate the maximum temperature that can reach the freezer or freezer. Each star equals at least six degrees (-6 ° C). To Freeze require at least -18 ° C. A 4 star freezer, ensures that reach temperatures below + a least twenty-four degrees (-24 ° C). The refrigerator-freezer (no freezer) generally have two stars, this means that cooled to -12 ° C.
ELECTRICITY CONSUMPTION Since it is difficult to determine how much you really spend the refrigerator, as advised reference to look at the nameplate power of the compressor. While this does not indicate the efficiency, at least give a rough idea.
EFFICIENCY OF THE CABINET Factors to consider are: a) integrated magnetic weather-stripping doors (no screws): When the seal is integrated into the door is sealed and virtually trouble-free oxidation of screws, it does not. b) Weather stripping widths, to prevent loss of cold. c) Quality of insulation, which for efficiency should be made of polyurethane foam. d) Quality of paint should be bright, be soft and smooth to loosen the dirt more easily. Look at the joints between metal parts and in the corners, if any chip or defects.
ADJUSTABLE SHELVES AND SHELVES IN REFRIGERATOR
If you need to adjust, raise or lower shelves or racks, should be done with simplicity and comfort. If the shelves are glass must be tempered glass spill-proof type, which may contain free liquids to continue falling at the lower shelves.
Fruit and Vegetable Crispers

Fruit and Vegetable Crispers
OPENING WITH OSCILLATING It is important to have a crisper for fruits that allows you to remove your food without having to open the door completely and remove the crisper, which usually causes the typical broken weatherstripping FRUIT TRAY HOLDER Acrylic slip resistant and edges.

Frost is no system that incorporates some currently consists of a cold air cooling system that prevents frost formation on the device and therefore need to be thawed twice a year. This is because the cool air, do not have cold surfaces where moisture condenses. It consists of a motor that cools the freezer and a fan that distributes air evenly.
The refrigeration vans can take the No Frost the entire device or only in the freezer.
In the case of vans carrying this system in the entire apparatus, as it has no two engines as the traditional (one for the fridge and a freezer) is usually translated into increases in consumption so that the energy rating of these devices usually "B" except the high end (Miele and Liebherr) they get 'A' levels.
This system preserves food for longer than the traditional system. The only precaution to take is to store food in suitable containers tightly closed as the cold and dry is issued if the well is dry we cover.
