Why You Should Choose The Right Dehumidifier?

How to choose refrigerator? Types and criteria of choice

There are many different refrigerators types and sizes. So you can choose the right model. What features do modern refrigerators have? We’ll talk about this now.

Refrigerator types

First of all: there are four refrigerator types: single-chamber, two-chamber, model Side-by-Side, multi-chambered. Such models differ from each other only in the number of cameras and freezer location.

In a single-chamber refrigerator freezer (if there is one; there are models without it) mounted in the top of the device. It usually has small volume and represents box with its own door, but it is situated behind the refrigerator door.single-chamber refrigerator

Freezer compartment is not a part of the refrigerator if we talk about two-chamber devices. Freezer may be located above the cooling chamber, but models with bottom freezer location are more popular in our country.

Side-by-Side format (it is also a two-compartment refrigerator) provides refrigeration and freezer following one near another. The most common location is: freezer at the left side (it has its own door), at the right side – the refrigerator compartment (also with an own door). Cameras can be swapped, then the freezer switches to the right side. Type Side-by-Side can boast its great roominess, so large families prefer these devices.

In multi-chambered freezer are often located under the refrigerator compartment. It may consist of 2-3 pull-out boxes (such format is also called French door).

One chamber may be a zone of storing fresh fruits and vegetables (with high humidity and own temperature settings). Sometimes camera of quick deep freeze is provided. Some models have even a camera, where the products can quickly defrost or warm up. Behind one of the doors there is hidden storing wine compartment. Multi-chamber refrigerators have a variety of layouts. These models are more expensive than two-chamber, but often their price no more than the cost of Side-by-Side devices.

Refrigerators for wine (wine cabinets) do not have a freezer. This device combines one or two (rarely – three) temperature zones for high-quality wine bottles storage. You can also set the desired temperature for the wine.

Аridge dimensions

Dimensions of refrigerator are an important criterion. You must know the place, where you’ll install the device and on this basis, choose a model.

The most popular are two-chamber refrigerators with bottom freezer. They have a height of 140-205 cm. Their depth is typically about 60 cm, and width – 60-70 cm. Single-chamber models rarely have height above 130 cm. Models without freezer may be lower (about 90 cm). Their depth is usually 50-60 cm (but there are models with depth 47 cm) and width – 50-62 cm.

Refrigerators Side-by-Side can have width over 120 cm, but their standard width is about 90 cm. Their height and depth is not different from height and depth of two-chamber devices.

Multi fridges height is usually not less than 160 cm, width -. 80 cm to 120 cm, depth is often no more than 70 cm.

Capacity

This parameter depends on the size. Larger refrigerators dimensions mean more spacious of the device. In the performance can be indicated the full of the useful volume. Here second rate determines real capacity, so pay more attention to it.great capacity

Single-chamber refrigerators have the lowest volume. It can begin with 80 liters, while the maximum – 200-250 liters. The volume of two-chamber models can reach up to 300-350 liters. In classical Side-by-Side devices the volume is about 400-600 liters, although there are several models of smaller volume (200 liters) or, alternatively, a larger (700 liters). Approximately the same performances have multi-chambered models.

Wine refrigerators capacity is usually measured by the number of bottles that can be simultaneously stored in it. The smallest typically intended for eight bottles, but there are also models for 50 bottles.

Remember that the useful volume of the refrigerator is the main indicator. Choosing a refrigerator worth consider amount of food enough for a family. If you do a lot of reserves for the winter or there is the practice of a buying a lot of food once every 2-3 weeks, you must take the model with freezer more or not less than 100 liters, and preferably about 150 liters. If you prefer fresh products pay attention to the volume of the refrigerator compartment, the presence of special zones for better storage of vegetables, fruits, meat and seafood. Refrigerator with a useful volume of 250-300 liters is enough for a family of 2-3 members. If the family is larger, and place in the kitchen is so too, you should think about more spacious model.

Defrosting

All modern fridges have auto defrost system. More often it is so-called drip system. While compressor works ice is forming on the cooling element. It is located behind the rear wall of the device. Because of the temperature differences on the cooler back wall inside the compartment moisture accumulates. It can become a small layer of hoarfrost.

However, the compressor is switched off after some time of working. Consequently, the ice melts and flows into a special container. Then it evaporates because of compressor warm. The user does not need to do anything, problems are minimal: keep the refrigerator compartment clean, and take care of channel, through which the melted water flows into the container for evaporation.

Freezer can have so-called hand-defrost system (low-end models) or auto – No Frost system. In models with such system cooling element is placed not in the walls of the freezer, but in the other “secret” place, that is out of reach for user view. There is also a fan in the freezer that blows cold air from this “secret” place. That is the No Frost system in simple words. There are also models of refrigerators with “complete No Frost» (Full No Frost), when freezer and refrigeration unit works with No Frost systems. Then both have a fan for supplying chilled air.

With No Frost user can completely forget about defrosting, but this system have certain disadvantages. For example, the smaller useful volume of the device because of the fan. Moreover, the airflow that is generated by the ventilator, is a source of additional noise. In devices with no frost system products must be well packed. Otherwise they will be rotten because of flows of dry cold air.

Fridges with No Frost or Full No Frost systems are usually more expensive than models with drip systems. However, the price difference is not as great today as a few years ago.

Number of compressors

Fridges often have one compressor. It will be enough for the cooling chamber and freezer. Modern models allow you, if necessary, to keep freezer in active mode, and cooling chamber you can off or activate eco mode, but all food you need to replace. Such a function named “Holiday”. This is possible even with one compressor.

But also there are many refrigerators with two compressors. In such models cooling chamber and freezer are completely independent of each other. You can at any time to enable or disable any camera, each has its own independent temperature control and it’s really good.

Side-by-Side or two-chamber fridges may have one or two compressor. Two-compressor devices don’t differ from single-compressor models by level of noise and energy consumption.Inverter power compressor

More and more modern refrigerators have a so-called inverter compressor. In this instance compressor has a special converter current. It works constantly but with varying intensity (power), and its optimal at any given time in order for keeping desired temperature in the refrigerator and freezer. Usual compressor works discretely: periodically turned on at full power, then switched off and so on.

Inverter compressor switches on rarely, so it runs-out a long while. Also Inverter refrigerators consume less electricity and they have lower noise level. Devices with inverter power control of the compressor are more expensive price difference isn’t very large.

Power and freezing

If it is important for you to freeze many products, for example, after buying them at the supermarket, note this option.

Freezing power measured in kilograms. It may range from 3-4 to 10-12 kg depending on the model of the refrigerator. This is amount of food that freezer can freeze per day.

Freezers power determines how long products in it will be usable. According to the generally accepted standard freezers are divided into 4 types. Each is designated with a certain number of stars (snowflakes):

  • One star (*) means that the temperature in a freezer can be reached to -6 degrees. It determines, that food will be OK in 7 days here.
  • Two stars (**) – temperature to -12 degrees and expiration date no more than 30 days.Three stars (***) – temperature to -18 degrees, expiration date 90 days.
  • Four stars (****) – temperature below -18 degrees, expiration date 6-12 months.

Often it happens, when three stars have one color and another one star denoted with more light color. It means that the freezer can temporarily maintain the temperature below -18 ° C – for quick and deep freezing.

Climate classes

Refrigerators climate class shows, at which temperature it is able to qualitatively work.  It is desirable to correlate determined climate class with a real temperature in the room where device will work.

International standards identify several climatic classes refrigerator: N, SN, ST, and T:N (normal) – device will work with ambient temperature +16…+32 °С.SN (subnormal) – +10… +32 °С.ST (subtropiс) – +18… +38 °С.T (tropic) – +18… +43 °С.

There are models with several climatic classes, so they have wider temperature range (for example, the SN, T).Energy efficiency

As with other household appliances, refrigerators also have energy efficiency classes. Marking – letters A, B, C, D, E, F, G. Class A – the most fuel-efficient models, G – high consumption of electricity. On sale, in the main, there are refrigerators with energy efficiency class not lower than B.

Class A recently became wider. So there are classes A+, A++, A+++. These models have even lower power consumption than devices with A-class. Every sign here means additional 10% electricity saving. But these refrigerators are usually more expensive, but later it will justify its cost.

Control systemBudget refrigerators typically have electro-mechanical control – by turning knob user can select intensity of refrigerator and freezer. There are two such controls in two-compressor models – for every compartment. Function “superfreezing” can be activated by a special button. That’s all control system.

Models with electronic control are more expensive, but they give the user more possibilities of refrigerators turning. Typically, such models have a display as a control panel. You can set desired temperature in both compartments, activate various additional features and functions.

Remote control

Refrigerators with electronic control can be remote controlled control from your smartphone or tablet. This is possible thanks to the application, internet connection or Wi-Fi-zone in the room, where refrigerator is located. Remote control allows you to perform all basic settings of the refrigerator work from anywhere at home, city and the world. In such a way you can change temperature, turn on “vacation” mode, activate “superfreezing” option, control energy consumption and so on…These devices also can tell the user what products are in the fridge, buy online store missing, give some propositions about cooking recipes with existing products and even tell that you need to buy for the selected recipe.

Additional modes and functions

The main task of the refrigerator is providing the preservation of food and increasing their shelf life. It has not been canceled. But modern refrigerator can offer for a user a variety of additional features. And we’ll talk about them.

Multi-cooling in the refrigerator compartment – a new system that provides a supply of cooling air to every shelf. So does a distribution fan. This system is very important in devices with glass shelves, because there movement of air is more difficult. So there temperature in different parts of the compartment may be different.

Mode “Holidays” or “Vacation” is activated just at travel time, when the owner is not necessary to use the refrigerator. If these modes are activated freezer will work normal – there is no necessity to take off all products. But the refrigerator compartment, where usually products with a short shelf life are, goes into economy mode, so user must remove all food from there.

Freshness zone is intended for different fresh products storage. There is one container can be secluded for a zone of freshness it the refrigerator compartment. And it will be so-called wet freshness zone (humid), which is ideal place for the storage of fresh vegetables, fruits.

The “door to door”. This feature is implemented in some LG models.  Behind the door of a refrigerator there is another smaller door. Behind it a small compartment for drinks and products that uses very often. So user will not open the main door, and cold air will not leave the main compartment. It involves a significant cost of electricity.

“Superfreezing” – maximum intensity mode, which is used for quick freezing of new products.

Sound alarm – if user forgot to close the door of the device, the alarm remind to close it. Also sound alarm will be activated if the temperature will quick go up (it can be if refrigerator accidentally was turned off of network).

Cold water feed. Conveniently, if the refrigerator has such a function – you can always quench thirst with cool water.

The same can be said about the automatic icemaker – you can’t find such function in budget refrigerators. An ice maker may produce a certain amount of ice cubes in an hour. Also it can grind them. If there is an ice maker, there is often cold water feed function.

The level of noise

The last criterion of choice we know. Quite an important parameter, especially if the refrigerator will work in a small apartment or studio, where the kitchen and living area are one space. The normal rate for a modern refrigerator is no more than 40 dB. That noise you almost can’t hear. If there is higher rate, it is better to look at another model.

We really hope that we helped you to select the refrigerator.
