View of an expensive kitchen in a modern house
It is present in every household; everyone knows it and knows its advantages – the refrigerator. Surely you know this when the electricity fails, and everything starts to defrost in the refrigerator or the fridge/freezer combination?
Not only does it do a lot of work until everything is cleaned up because before you get it, everything is spoiled and has to be disposed of. This is not only annoying but expensive. Then you quickly come to the realization that without this “cool helper” it is hardly possible in the household.
The question now is: which refrigerator is best for me (or us)? Does this home appliance fit into my (or our) kitchen? So, this blog or some forums can help and give you some tips.
What is a Refrigerator?
A Refrigerator is a complex household appliance in the form of a cabinet, which is able to cool the interior down to a minimum temperature (or to a temperature of your choice) by means of integrated coolant and electrical power supply, thus extending the shelf life and freshness of your food.
The outer shell is thermally insulated, preventing the cabinet’s cooling from escaping to the outside or from allowing the heat of the outside temperature to penetrate inwards. Through an exhaust air system, the heated air is transported outwards, room air is attracted and cooled again, in a continuous cycle.
What Types of Refrigerators Are There?
When people started to want to make their food more durable, and that’s more than 2,000 years ago), they encountered cold. This prevents rapid soiling and leaves meat, vegetables, fruit, drinks and other foods fresh for longer.
First of all, it was a box of wood, laid out with insulation materials, and in it, there were blocks of ice, which a coachman transported to the respective places. This was called a freezer, which is still a common term for the refrigerator.
Fortunately, since the middle of the 18th century, capable minds have thought about it and developed it further. Since the 1930s, it has been part of the basic household budget, or something similar to what we know it to be. At this time, there are numerous devices on the market that you are spoilt for choice.
The thermoelectrics is used in a portable Refrigerator, better known as a cooling box, uses and works according to the so-called Peltier effect. They can be used in different ways, have a 12 V connection and work very quietly. Since the power consumption is relatively high, this household appliance should not be used for long-term use.
The absorb refrigerator can be found, for example, in caravans and mobiles, some also in hotels. The principle is based on an ammonia/water mixture, which is heated in different ways (e.g. with gas, 110 V / 220 V power source or solar technology) so that these two elements can separate. The water now flows back into the absorber without ammonia. However, the ammonia, by heating, has become gaseous, hot steam and enters the capacitor via the intended connections. By now dissipating its heat back to the outside, it goes back to a liquid state, is transported into the evaporator to connect with hydrogen. This turns the liquid ammonia back into gas. This whole process then causes the interior to be cooled. But even this method is not necessarily suitable for continuous use.
The compressor refrigerator is found in most cases in our households, but also in industry. The operation is similar to that of the absorber device, but much more efficient. The gas does not have to be separated from the water first, is operated exclusively via the socket and cools faster and better.
These household appliances have, of course, also been adapted to the tastes of consumers.

Benefits & Function
the advantages of a refrigerator, a freezer, box or any other version of this device are obvious. Although it is not too problematic in winter, when there is a maintenance or repair or simply a failure of the household appliance, it is already a real disaster in the hot days of the summer months when the refrigerator is broken.
As with any household appliance, the better it is maintained, the longer you enjoy it. If you also looked at the efficiency classes before you buy, the joy is twice as great when the electricity bill comes into the house.
Since the functions are almost the same for every refrigerator, there is not much to be said for this. However, the commissioning of the various devices is also different. All you need to do for the home appliance is to find a suitable power source (socket) so that the refrigerator can start and cool.
The various settings can be taken from the operating instructions, and it can be cooled effectively.
A little Tip:
If you pay attention to how you store your fridge or freezer, then you can get even more efficiency in the shelf life of your food. It is also good to know how the temperature is distributed in the cooling device. It is actually the same as at room temperature, the warm air rises and cool air sinks to the bottom. This can also cause differences of up to 7°C in your refrigerator. The coldest month is, therefore, on the glass plate and the very back, so the back wall is the mildest temperature in the storage compartments in the door and in the drawer below the glass plate, where the vegetables and fruit (except sensitive tropical Fruits) are best.
In the rear part and on the glass plate easily perishable, i.e. sausage, fish and meat, should be admitted and the freshly bought again and again to the rear clear. In addition, you can store dairy products (cream, cottage cheese, yogurt, etc.). At the top, you can make room for smoked fish or meat, cheese and leftovers. Light refrigerated goods and bottles fit in the door of the refrigerator.
The packaging also usually contains information about the optimum cooling temperature, in addition to the expiry date.
