There are two types of people in the world: those who read the fridge manual and those who press buttons until something beeps. If you belong to the second group (we are many), you’ve probably landed on the right post. We’re going to take a quick look at what each function<\/strong> on a modern fridge actually does, when it’s worth switching on<\/strong> and how it affects your electricity<\/strong> bill. We will do it with examples from Teka fridges, because that’s where we come from, but also because they cover most of the innovations you can find right now in the world of kitchen appliances.<\/p>\n

\"Teka<\/p>\n

What are the functions of a modern fridge actually for?<\/h2>\n

At this point, a fridge<\/a> is quite a bit more than the one keeping the drinks cold at your grandparents’ house every summer. It has become the indispensable appliance in any home (nearly all households in Europe and North America have one or more fridges), and it’s the appliance that spends the most time plugged in. On top of that, it regulates internal humidity to preserve each type of food,<\/strong> distributes air, separates zones by temperature<\/strong> and learns when to cool more or less. Knowing what each function does is the difference between throwing away half a kilo of fruit every fortnight or stretching the weekly shop by an extra week.<\/p>\n

\"Several<\/p>\n

The difference between a basic fridge and one with advanced technology<\/h2>\n

A basic fridge<\/a> with a freezer maintains a more or less stable temperature, and its cooling intensity is relatively adjustable depending on the season. In other words, it does the job. One with advanced technology<\/strong> distributes cold evenly,<\/strong> adjusts consumption<\/strong> based on actual use, keeps each food in the right zone under the best conditions and, above all, doesn’t need you hovering over it. The difference shows up in three main ways: less waste, lower consumption<\/strong> and less maintenance<\/strong> and effort on your part.<\/p>\n

How the functions affect preservation and energy savings<\/h2>\n

Functions used well reduce consumption and waste simultaneously. A No Frost system eliminates the need for manual defrosting and scraping sessions every other week. Good air circulation means fewer minutes of the compressor running. And a well-adjusted<\/strong> compartment stops the freezer from working flat out just to chill a bottle of water. All the small details are relevant when it comes to energy use and make for a more efficient appliance<\/a> overall.<\/p>\n

\"Teka<\/p>\n

Temperature control: the most important function and the least used<\/h2>\n

In some fridge freezers, you’ll find a dial at the back, in others on the side: you’ll come across it in fridges from any brand. When you bought the appliance, you noticed it existed, but now you can’t quite remember where it is. Which is a shame, because it matters: depending on how it’s set, your fridge cools<\/strong> more or less according to the season. When the ambient temperature<\/strong> is 10\u00b0C, your fridge isn’t working nearly as hard as when it’s 30\u00b0C outside. Bear in mind that the dial, which typically goes from 1 to 5, doesn’t refer to degrees Celsius but to cooling intensity levels,<\/strong> where 1 is the minimum and 5 (or higher) is the maximum.<\/p>\n

With Teka, all fridges come with a recommended and preset temperature, self-regulating as they go. You can see this on the digital displays, often located on the outside of the door or just inside it. But you also have the option to control these temperatures manually if you prefer, to personalise them according to your needs.<\/p>\n

\"Close-up<\/p>\n

How to set the temperature correctly depending on the time of year<\/h2>\n

The recommended<\/strong> fridge temperature is between 4 and 5\u00b0C, and the freezer should be at -18\u00b0C. In summer, with a warmer kitchen, it’s worth lowering the fridge temperature by one degree (without overdoing it) to compensate for more frequent door openings. In winter, you can ease off. Going up or down one degree can mean up to a 5%<\/strong> variation in consumption, so it’s not a minor detail.<\/p>\n

Don’t forget holiday<\/a> mode. Not every fridge on the market has it. With Teka, you can select it, and the fridge compartment will sit at 15\u00b0C while the freezer stays at its -18\u00b0C. The idea is to leave the fridge empty<\/strong> without having to unplug it entirely, because if you do unplug it and forget, you’ll come home to an entirely new ecosystem living on every shelf.<\/p>\n

\"A<\/p>\n

Temperature zones: what they’re for<\/h2>\n

Not everything keeps well at the same temperature. Meat and fish need close to 0\u00b0C; fruit and vegetables prefer something slightly warmer; dairy sits in the middle. Modern fridges integrate zones such as the Cooling Box<\/strong> (between 0\u00b0C and 3\u00b0C) or the VitaCare Box<\/strong> and FreshBox<\/strong> for controlled humidity. The FreshBox system reduces airflow to prevent vegetables from drying out, so even your half lemon has a chance.<\/p>\n

What does independent fridge\/freezer temperature control mean<\/h2>\n

DualTemp Control<\/strong> technology keeps two independent working cycles for the fridge and freezer. The upside? Opening the fridge doesn’t affect the freezer and vice versa. It also puts an end to cross-contamination of smells and flavours (ice cream that tastes faintly of last night’s leftovers is a classic nobody will miss).<\/a><\/p>\n

TotalNoFrost: no frost and no manual defrosting<\/h2>\n

How Teka’s TotalNoFrost system works<\/h3>\n

Teka’s TotalNoFrost system is one of our favourite innovations:<\/strong> it eliminates moisture before it turns into frost and builds up on freezer food and walls. This is achieved through the circulation of dry, cold air throughout the interior. So you can say goodbye to Sunday afternoons defrosting the freezer with a hairdryer.<\/p>\n

What advantages does it have over static cold systems?<\/h3>\n\n\n\n\n\n\n\n\n

How much space and energy does it save in practice?<\/h3>\n

By not accumulating ice, the freezer retains its full useful capacity for years. And by maintaining more stable temperatures, the compressor starts up less often. The actual gain depends on the model, but the improvement in convenience is immediate. And in all honesty, given the usual methods people use to defrost and remove frost, having a system like TotalNoFrost generally extends the life of the appliance.<\/p>\n

AirFlow Control: cold that reaches every corner<\/h2>\n

Why air circulation matters for better preservation<\/h3>\n

Without circulation, cold stays where it falls. AirFlow Control distributes cold air evenly across every shelf, preventing the top shelf from sitting at 6\u00b0C while the bottom is at 2\u00b0C. It eliminates temperature fluctuations, and that has a clear impact on how fresh your food stays.<\/p>\n

\"How<\/p>\n

How to activate and configure AirFlow Control<\/h3>\n

On models that include it, it works automatically from the moment you plug the fridge in. There’s nothing to adjust. The only thing to bear in mind: don’t block the air vents with oversized containers pressed against the back. That’s the equivalent of closing the radiator valves and then complaining it’s cold.<\/p>\n

FreshBox: specific preservation for each type of food<\/h2>\n

What the FreshBox drawer is and which foods it’s ideal for<\/h3>\n

The FreshBox reduces airflow and prevents fruit and vegetables from drying out.<\/strong> Lettuces don’t go limp, peppers don’t wrinkle, and blueberries last as long as they should (not as long as luck decides). A compartment like this helps preserve nutrients<\/strong> for longer. Given the kind of lives we lead (eating at home three days in a row and then not setting foot in the kitchen for anything more than a coffee),<\/a> it’s reassuring to know you won’t have to throw out half the fridge every week depending on how your work and social calendar is playing out.<\/p>\n
