Choosing a Fridge this year has ceased to be a simple task based on the principle “if only it freezes.” The home appliance market is undergoing major changes, introducing new standards for energy efficiency and climate control. The buyer today faces a dilemma: overpay for innovative freshness preservation systems or limit yourself to proven classics.
The modern market dictates its own rules, and old models with mechanical controls are becoming a thing of the past, giving way to smart devices. It is important to understand that main characteristics a refrigerator is determined not only by its service life, but also by the quality of food storage, as well as noise level and electricity consumption.
In this article we will analyze in detail what parameters you should pay close attention to when purchasing, so as not to be disappointed in the choice after a couple of months of operation. We will look at the types of defrosting, compressor designs and features of the internal space.
Type of defrosting system: No Frost or Drip?
The first thing you will encounter when studying the characteristics is the type of defrosting system. Traditional drip system (Direct Cool) works on the principle of natural defrosting of the rear wall of the evaporator. The water flows into a special tray and evaporates. This is a time-tested method that provides optimal humidity for storing vegetables.
However, most buyers in 2020 prefer the system No Frost. In such refrigerators, moisture does not accumulate on the walls, but is forced out. This eliminates the need for manual defrosting and ice formation. But there is a nuance: the air in the chamber is drier, which may require packaging of products in containers.
There is also a combined system where the drip method is used in the refrigerator compartment, and No Frost in the freezer. This is a compromise option that allows you to preserve the juiciness of vegetables and avoid ice in the freezer.
⚠️ Attention: If you choose the No Frost system, be sure to check the presence of a “crying” wall in the refrigerator compartment or an air humidifier, otherwise the greens will wither faster than usual.
When choosing between technologies, consider your rhythm of life. For those who value time and do not want to monitor the condition of the back wall, Complete No Frost will be the best solution. Fans of natural storage conditions should take a closer look at drip models or hybrids.
Compressor: Inverter or conventional?
The heart of any refrigerator is the compressor. Traditional linear compressors operate on the “on, full power, off” principle. This causes temperature changes and increased noise levels during startup. In addition, constant switching cycles increase electricity consumption.
Inverter compressors work differently: they do not turn off completely, but only reduce the speed to maintain the set temperature. This ensures quieter operation and stable temperature conditions. The service life of such units is usually longer, and energy consumption is 20-30% lower.
It is worth noting that inverter models are initially more expensive. However, the difference in price pays for itself in a few years due to energy savings. Also
If the budget is limited, a regular compressor is a completely workable option, especially in models of trusted brands. But if you are looking for maximum comfort and silence, then inverter technology is the uncontested leader in 2020.
Dimensions and useful volume: how not to make a mistake with the dimensions
Buying a refrigerator does not start with a trip to the store, and from the measurement of the kitchen opening. The standard width of 60 cm is not suitable for all kitchens, especially in older houses. Narrow models with a width of 55 cm or even 40 cm can be a salvation for small-sized apartments, but they useful volume will be significantly smaller.
Height also plays a role. Tall models (up to 2 meters) can hold more, but getting food from the top shelves can be inconvenient. Low refrigerators often require the installation of an additional freezer or chest if you are stocking up for the winter.
| Size | Height (cm) | Width (cm) | Volume (l) |
|---|---|---|---|
| Compact | up to 150 | 50-55 | 150-250 |
| Medium | 150-180 | 55-60 | 250-350 |
| High | 180-205 | 60 | 350-500 |
| Side-by-Side | 170-200 | 80-120 | 500+ |
When planning the installation site, do not forget to leave gaps for ventilation. The refrigerator should not be placed close to a wall or furniture. The minimum space at the back and sides is usually 5-10 cm, which is indicated in operating instructions the specific model.
The volume of the refrigerator must be calculated based on the number of family members. The basic formula is: 50 liters per person plus 20% reserve. For a family of three people, a unit with a volume of about 250-300 liters would be optimal.
Energy efficiency and climate class
In the context of constantly rising electricity tariffs, energy consumption class comes to the fore. Models of class A+ i A++ consume significantly less resources than their predecessors of class B or C. The difference in electricity bills over 10 years of service can amount to the cost of a new budget refrigerator.
An important parameter is the climate class, which indicates at what ambient temperature the equipment operates stably. For Russia, classes N (normal) and SN (subnormal) are relevant. If the refrigerator is in an unheated room, for example, in a garage or in a country house, a class SN-T (universal) is required.
⚠️ Attention: Operating the refrigerator at temperatures below +10°C (for class N) can lead to freezing of the oil in the compressor and failure of the unit. Always check the technical data sheet.
Modern models are often equipped with “Eco” or “Vacation” modes, which allow you to switch the refrigerator to an economical operating mode when you are away for a long time. This is a useful feature for summer residents and travelers.
Shelf material and internal content
The quality of the internal space directly affects ease of use. Shelves must be able to support heavy pots and jars of pickles. The leader here is tempered glass, which is stronger and more aesthetically pleasing than plastic or grilles. Glass shelves are easier to clean and do not absorb odors.
Pay attention to the vegetable storage system. The presence of a separate zone with controlled humidity (Zero Zone or equivalent) allows you to store fruits and meat at a temperature of about 0°C, which significantly extends their shelf life without freezing.
- 🥦 Containers for vegetables: must be voluminous and have perforations for air circulation.
- 🥛 Shelves on the door: check if there are holders for tall bottles and deep cells for milk.
- 🧊 Egg tray: in modern models they are often removed, since it is better to store eggs in their original packaging, but its presence is a matter of habit.
The number of shelves should be adjustable in height. This will allow you to place tall baking dishes or watermelons inside. The mechanism for rearranging shelves should be simple and reliable so as not to require effort when rearranging the space.
Noise level and additional functions
Noise level is a critical parameter for kitchens combined with a living room or studios. A level of up to 40 dB is considered normal. Models with a noise level above 42 dB can create discomfort at night, especially if the kitchen is located next to the bedroom.
Among the additional features, it is worth highlighting the presence of a display, a quick freezing zone Super Freeze and antibacterial coating. The display is convenient for temperature control, but in budget models it is often just a decorative element that increases the cost.
What is a freshness zone?
A freshness zone is a separate compartment in the refrigerator where the temperature is maintained at about 0°C and optimal humidity. In such conditions, meat, fish and herbs remain fresh 2-3 times longer than in a conventional chamber without freezing.
The quick freezing function is useful if you often load a large amount of warm food into the freezer. It temporarily turns on the compressor at maximum power. However, it is not recommended to use this mode all the time, as it increases the wear and tear of the equipment.
Overview of popular brands and price segments
The refrigerator market in 2020 is represented by many players. European and Korean brands, such as Liebherr, Bosch, LG and Samsungare traditionally considered to be leaders in reliability. They offer advanced technology, quiet inverter compressors and high build quality, but their price is often higher than average.
Chinese manufacturers such as Haier and Hisenseare aggressively conquering the market by offering excellent value for money. Their models often copy the functionality of premium brands, but cost 20-30% less. Assembly in China has ceased to be synonymous with low quality.
The budget segment is occupied by brands Atlant, Beko i Indesit. These are “workhorses” that may not have exquisite design or quiet operation, but they perform their main function - they freeze. Repair of such models is usually cheap and available at any service center.
☑️ What to look for in the store
When choosing a brand, you should also consider the availability of service centers in your region. Buying a rare brand can turn into a problem if after 3 years you need to replace a specific part, which will have to wait for months.
Frequently asked questions (FAQ)
Do I need to let the refrigerator sit after delivery?
Yes, this is required. If the refrigerator was transported lying down or simply tilted strongly, the compressor oil needs time (from 2 to 4 hours) to drain back into the compressor crankcase. Turning on ahead of time can lead to water hammer and breakdown.
Why is the refrigerator humming loudly?
There may be several reasons: incorrect installation (legs are not adjusted), proximity to the wall, compressor or fan malfunction. If the humming appears suddenly and is accompanied by vibration, you should call a technician.
Is it possible to place the refrigerator next to the battery?
It is highly not recommended. The proximity (of heat sources) forces the compressor to work in increased mode, which leads to excessive energy consumption and rapid wear. The minimum distance from the battery should be 50-70 cm.
How often do you need to defrost a No Frost refrigerator?
Technically, the No Frost system does not require defrosting to remove ice. However, once a year it is recommended to turn off the refrigerator for general cleaning, washing and treating with antibacterial agents.
