Capacity
The temptation of many is to buy a fridge as big as possible, which is not exactly inspired by both the purchase cost and the cost of operating it, without mentioning the space occupied in the home. A refrigerator works the better and more economical, the less air inside, so the fuller. From this point of view, the ideal size is the one that under normal conditions of use is almost full, remaining an empty shelf for any unforeseen situations. A larger appliance also means a higher purchase price and a significantly higher monthly bill, so it is wasting from all points of view.
Another reason to avoid buying a larger refrigerator than is really necessary is psychological. Researchers have shown that no matter how big the fridge is, people have an instinctive tendency to fill it. Refrigerated products not having a long shelf life, large quantities of food will reach the garbage, breaking down in the refrigerator. Thus, a refrigerator too large instead of lowering food expenses will only raise them further.
Dimensions
Given the wealth of models on the market, I think we can find a device relatively easy to meet personal needs and possibilities. To avoid any pleasant surprises, it is important that before we go to buy a refrigerator, we must measure the available space in the place where we intend to place it. It should also be borne in mind that in order to ensure optimum ventilation in order to eliminate the heat, you will have to leave some space behind the refrigerator and on the sides.
Also the dimensions of the door in the open position must be taken into account and the fact that there will have to be room to move around the open door. From this point of view, the models with two doors are advantageous, these occupying a significantly smaller space in the open position than those with a single door. If you have chosen a model with a large door, pay attention to the direction in which it opens. In the models with reversible doors the sense of opening can be changed at any time, but in those without this constructive facility it is important to make sure from the beginning that they fit in the available space.
Interior compartment and doors
By size, the most important thing in a refrigerator are the possibilities of interior partitioning. The ideal situation is when the position of the shelves can be adjusted according to needs in steps of maximum a few centimeters. If the shelves are fixed, we must be careful about the distance between them. It is often the case that this distance is a few millimeters lower than the standard height of the jars in commerce, which is extremely unpleasant because removing the shelf from above creates too much space, a waste. If the refrigerator comes with plastic boxes, they should be easy to remove.
The interior of the refrigerator
Compartmentalization is equally important when it comes to the refrigerator door. The position of the door brackets should be height adjustable and their width should be sufficient to fit 2 liter juice bottles.
Elevating shelves
It is a feature found in some refrigerators at the top of the range. The elevating shelves have a mechanism that allows them to move vertically without removing them from the refrigerator and especially without emptying them of products.
Defrosting
There are three variants of defrosting refrigerators, each with its own advantages and disadvantages. In the case of refrigeration units, various combinations of them can be found.
Manual defrosting
In the past, it was the only possibility of removing the moisture accumulated indoors, today it is only found in the cheapest models. It is a rather uncomfortable operation, which must be repeated regularly. If it is too late to defrost the refrigerator, its performance decreases and the power consumption increases significantly.
Automatic defrost
Refrigerators with automatic defrosting are constructed so that the water resulting from defrosting is collected in a special compartment at the bottom, where it flows out of the refrigerator, into a tray above the compressor. From here it will evaporate, being helped and the heat released by the compressor during operation.
No ice (no frost)
In this system, the formation of ice inside the fridge is no longer possible, cooling is carried out by ventilating the interior with cold air currents. The more expensive variants use multiple air columns, something that has been passed on in marketing materials under different names, depending on the brand (MultiFlow, Multi AirFlow, Multi-Net, etc.).
