frost

Nowadays most refrigerators are “No Frost”, but… what does this really mean? Perhaps what you have heard the most is that they do not make frost, but they also have other peculiarities with respect to the more traditional models. For this same reason, today we are going to review the differences between both types of refrigeratorswith the advantages and disadvantages in each case. How a No Frost refrigerator works No Frost refrigerators use fans that constantly remove the coldwhich prevents water vapor from condensing on its walls. Since there is a constant, dry air flow, moisture does not accumulate in the form of ice, which prevents us from having to remove it ourselves. In addition, many models have a system that allows you to eliminate small traces of ice if they appear. This No Frost system has some especially interesting advantages beyond not forming frost. By having a constant air flow, this cold air reaches all corners of the refrigerator equally, homogeneously, which allows all foods to be preserved better for longer. Now, it’s not all advantages. When using a No Frost refrigerator, it is advisable that we take into account that your air system is dryand by reaching all corners evenly it can dry out food, especially fresh items such as fruit, sausages or vegetables. We must also pay special attention to another point: No Frost refrigerators consume a little more because they have a resistance that heats up to melt the ice automatically. For this reason, we recommend looking at the annual consumption in kWh, and not only at the letter of energy efficiency. How a cycle refrigerator works Cyclic refrigerators (also called Low Frost either Less Frost by some brands) are the traditional ones, the traditional ones. They work through a refrigerant gas that travels throughout its circuit until it reaches the desired temperature, at which point the air flow stops. It does not work using fans, so they can generate less noise than No Frost. As the cold of these refrigerators is humid and they do not have a fan that constantly stirs the air, plaques of frost can form on the walls, which forces us to remove them manually so as not to compromise their efficiency and durability. Additionally, if too much frost forms, the refrigerator motor may have to work harder, which means possible increase in electricity bill. The good thing about these refrigerators is that by having a system that generates humid cold, food is usually better hydrated, preserving it better for longer. This occurs especially in fresh foods such as vegetables, which hold up better without drying out. The good of both worlds We can also find refrigerators that bring together the best of both worlds: hybrid refrigerators. In this case, they come with both systems, but separate: the No Frost system in the freezer and the cyclic system in the refrigerator. This prevents frost from forming in the freezer and allows the fresh food in the refrigerator to stay moist for longer. In other words: mixed models come with a No Frost freezer which prevents us from having to chip away at the ice that forms every so often and they also have a cyclical or dynamic refrigerator that prevent fresh foods, such as lettuce, from drying out. The good and the bad of both options, face to face No Frost Cyclic (traditional) THE GOOD 🟢 You do not need to remove the ice manually, the temperature is more homogeneous on all shelves and the food tends to cool faster thanks to the fan air system. They keep food fresh for longer and are usually quieter and cheaper. THE BAD 🔴 Their dry air can dry out fresh foods and they tend to be noisier due to the operation of the fan. Plus, they tend to be more expensive. They can form frost on your walls and can cause uneven temperatures on different shelves. Ideal for: Storing a lot of food in the freezer without the ice blocking the drawers or for families that open and close the freezer constantly, thus recovering the optimal temperature in a short time. Eat a lot of fruits or vegetables without losing moisture in a short time or if you want a refrigerator that makes little noise. We do the math to see which one can compensate you more. Each of the refrigerators has its advantages or disadvantages, so to see everything much clearer we are going to give a couple of practical examples. If you are looking for a refrigerator that allows you to use it without further ado, without worrying about removing frost every few months, a refrigerator with a No Frost system will compensate you much more. Actual use: Let’s say you usually freeze a lot of food. The accounts: No Frost refrigerators allow you to better recover the temperature by opening and closing the freezer many times. In addition, you avoid emptying it to defrost the ice every few months. So? It is a choice that lies in both the comfort and the usefulness of the freezer: fresh foods dry out more, but in exchange we have a freezer that better maintains its ideal temperature. If you opt for these refrigerators, at least have one or more drawers with humidity control, generally called VitaFresh or BioFresh. Although there are fewer of them in stores today, refrigerators that are cycled or have a traditional system can be very attractive, both for the preservation of certain foods and for other characteristics. Actual use: You don’t usually freeze a lot of food and you usually eat a lot of it fresh. The accounts: Having a cycle refrigerator allows fresh food to last better. In addition, by not using a fan constantly, they tend to make less noise. So? It is ideal if you consume more fresh foods than frozen foods or if you have the refrigerator next to, for example, the living room and you are looking for as little noise as possible. … Read more
