All about household refrigerator and how to buy it

+

   The site “Optimal Choice” survey was conducted on the topic: “What is the device in your home the most important?” It received 250 votes, and the results were as follows:

  • Refrigerator (40%, 99 votes)
  • The computer (26%, 65 votes)
  • TV (7%, 19 votes).

As you can see from the results, a fridge is the most important item of household appliances. The poll was a bit playful, but we can see general tendencies through it.

What is an electric refrigerator?

This is a device designed to store food and other substances by maintaining low temperatures in special insulated containers (cameras).

History of the kitchen refrigerator begins with the use of special facilities for the storage of ice, which was intended for the ancient kings. The technology of reception of artificial ice in a special device was invented in 1850 and used today.

The first industrial refrigeration units began to be used in 70-80 years of the 19th century, while the first household refrigerator appeared only in 1913. Mass production of fridges on the market began to develop only in the 30 years of the 20th century.

Today storing of food in a fridge is perhaps the core technology of storage, and refrigeration equipment has become very significant dissemination. Drying of products with using of household driers can be some alternative but it can’t to provide a full replacement.

The principle of refrigerator work is as follows: compressor sucks refrigerant (mostly Freon) and submit it to the condenser where the refrigerant cools, thus going from gas to liquid, after which it enters the evaporator, where he again goes into the gaseous state, cooling evaporator wall and through it the fridge camera.

Let’s get acquainted with the basic characteristics of the refrigerator in order to understand which of them is better suited for purchase:

1. Refrigerator form factor.

The first thing is to determine the form factor of refrigerator.

There are built-in and separate refrigerators.

A built-in refrigerator is designed so that it can be hidden in any niche, such as kitchen cabinet. This arrangement saves space and improves design.

Separate refrigerators are familiar to us “cases” which could be installed even on the middle of the room :).

The choice of form factor depends on the specifics of your interior and financial capabilities, because built-in refrigerator models are much more expensive than their separate analogs.

2. Type of refrigerator.

Refrigerator types depend on its functional design.

Most often we can see these types: single-chamber and two-chamber.

Multi-chambered household refrigerators and other types of refrigerators are a quite rarity.

Single-chamber refrigerator consists only of the camera or can also have a small freezer compartment. These models have only one door.

Two-door refrigerator has separate camera and freezer. Such device can also have one common to two cameras door (single door), but more often it has separate doors for each of the cameras. Having of two doors allows more efficient use and helps to avoid unnecessary loss of cold. That is why we can recommend buying of refrigerator with two doors.

3. The size and volume of refrigerators.

The sizes (dimensions) of the refrigerator often depend on the all interior.In addition to the size you need to pay attention to the refrigerator volume – the volume of its cameras, because this volume depends on what – how many products you can put in the fridge.

Single-chamber home refrigerators often have a relatively small size – an average of 150 (height) x 60 (width) x 60 (depth) centimeters.

A useful volume of such fridge can be of 250 liters maximum (an average of 130-150 liters). Such small compact refrigerator can be useful to small office or hostel.

The new large two-chamber refrigerator may have a height of 2 meters, while the width and depth are not very different from the single-chamber (an average of 80 x 80 cm.).

The volume of large refrigerators can be up to 550-600 liters. The most popular models have average volume about 250-300 liters.

Here you need to just focus on your needs and the size of living space. For the average family 250 liters model will be quite sufficient.

4. The number of compressors.

A refrigerator compressor is a device that provides coolant circulation and, as a result, cooling of chambers.

The model may have one or two compressors. One compressor works on all cameras simultaneously.

In fridges with two compressors each camera has its own compressor.

The presence of two compressors enables the independent cooling of each chamber and increase the efficiency of the device as a whole.

5. Energy class.

Energy consumption is a very important aspect in refrigerator choosing, because this device must be switched on permanently and therefore constantly consumes electricity at an average power of 300-400 watts.

To summarize the various energy options adopted a special classification. According to this classification different classes marked with Latin letters from A to G in the growth of energy consumption. That class A is the most economical.

But Class A also has several categories that are marked with the addition “+” sign. It can be of Class A+ or A++. The logic is simple – the more + – the more economical.

Basically class A++ have single-chamber household refrigerators, normal two-chamber fridges have class A or A+.

6. Thawing method.

Because fridge produces cold, then sooner or later it will begin to form frost and ice. So it becomes necessary to implement defrosting. For this purpose all models have a special defrost system.

The most common systems of refrigerators defrosting (thawing):

  • Manual system. Well, here everything is clear. This system can now be found only in some old refrigerator.
  • Drip (static) system. Its essence is that the moisture collected on the rear wall and drains into a special evaporator, from where evaporate with time.
  • No Frost system. No Frost is the most advanced system. With its use a special fan promotes such distribution of cold air that frost does not form at all.

In the two-chamber models can be used combined thawing, i.e. one camera can be defrosted by drip system and the other using No Frost.

7. Additional characteristics.

Additional refrigerator options, which should be assessed include:

  • Control features. The control of device work can be provided with a mechanical (via the handles) or electronic system. Many people say that electronic refrigerator control is more convenient and accurate, but mechanics seem more reliable.
  • Antibacterial coating availability. This coating helps preserve food longer due to exposure of silver ions.
  • The presence of wheels for easy transport.
  • Ability to select the direction of the refrigerator door opening.

Now you’ll know what is the best refrigerator for you.
