Many users of household appliances, faced with a breakdown or choosing a new model, ask the question: what exactly is the name of the freezer in the refrigerator? Often in everyday life these concepts are confused, calling the entire unit simply a “refrigerator,” although technically it is a composite device. Freezer compartment is a specialized compartment designed for deep freezing of products and their long-term storage at low temperatures. Understanding the correct terminology helps you quickly find the necessary information in the instructions or explain to the technician the essence of the problem.
In the design of modern refrigeration equipment, this unit can be designed in different ways. It can be a separate box at the bottom, the upper part, or even be placed in a separate case. Compressor and the refrigerant circulation system works to cool both circuits, but the temperature conditions in them differ significantly. In the main compartment, the temperature usually stays around +4°C, while in the deep-frozen zone it drops to -18°C and below.
When understanding the device, it is important not to confuse the chamber itself with the evaporator, which is located inside and directly cools the air. If you hear that “the freezer burned out,” most often we are talking about a compressor failure or a freon leak in the low temperature circuit. Proper use of terms will allow you to interact more effectively with service centers and better understand the operating principles of your equipment.
Official terminology and device
Technical documentation and GOSTs use a clear division. The main device that maintains cold is called refrigerator cabinet. There may be one or more compartments inside it. What we call a freezer in everyday life, engineers and manufacturers call freezer compartment or freezer compartment. If this is a separate, independently standing unit, then its correct name is freezer or chest freezer.
Structurally, this unit is a thermally insulated volume, inside which it is located evaporator. It is through the walls of the evaporator that heat is removed from the products. Depending on the defrosting system, ice may form here (in models with manual defrosting) or moisture will be removed automatically (in No Frost systems). Thermostat or an electronic sensor constantly monitors the temperature inside.
⚠️ Attention: Do not confuse the freezer chamber with a refrigeration compartment. An attempt to store perishable products (milk, fresh vegetables) in the freezer will lead to their spoilage and change in structure, since the water in the cells will freeze and tear the tissues of the product.
It is important to understand that the name also affects the energy efficiency class. Freezers consume more energy per cubic meter of volume than refrigerators due to the greater temperature difference with the environment. Therefore, manufacturers pay special attention to the quality of insulation (usually cyclopentane foam), which fills the space between the inner plastic and the outer metal casing.
Types of freezer compartment layouts
The answer to the question of what a freezer is called often depends on its location in body. The industry has developed several standard layout schemes, each of which has its own advantages. The most common scheme is where the freezer is located at the bottom. This is convenient for ergonomics, since the refrigerator compartment, which is used more often, is at eye level.
There is also a classic “Eurocabinet” layout, where the freezer is located in the upper part. This option is often found in models of the Soviet period and budget modern lines. The volume of the upper chamber is usually smaller, and it is intended for storing already frozen products, and not for their initial freezing.
- ❄️ Top Mount: Freezer on top, refrigerator compartment on bottom. Classic, time-tested design.
- ❄️ Bottom Mount: Freezer at the bottom. The most popular option in modern kitchens, often equipped with drawers.
- ❄️ Side-by-Side: Vertical division, where a narrow freezer is located on the side of a wide refrigerator compartment at full height.
- ❄️ French Door: A combination where the refrigerator compartment is on top with two doors, and the freezer is below in the form of a wide drawer.
The choice of layout affects not only convenience, but also repair. For example, in models Bottom Mount access to the compressor and condenser is often simplified, since they are located in a niche above the freezer. At the same time, in the diagrams Top Mount the pipeline system can be more branched, passing through the entire body.
Free-standing freezers: chests and cabinets
When they simply say “freezer,” they often mean a free-standing device that is not combined with the refrigeration compartment. Such units are divided into two main types: vertical cabinets and horizontal chests. Chest freezer (chest freezer) is a top-loading device that opens with a lid from the top. Thanks to physics (cold air is heavier than warm air and does not rise upward when opened), chest freezers are considered the most energy efficient.
Upright freezers look like narrow refrigerators and consist of a system of shelves and drawers. They take up less floor space but require more space to open the doors. Forced air circulation is often used inside such chambers, similar to the system in refrigerators, which eliminates the need for manual defrosting. Chests are often used for storing large volumes of products: meat, semi-finished products, berries. Their design allows you to place large items that will not fit into standard refrigerator drawers. No Frost in refrigerators, which eliminates the need for manual defrosting.
Chests are often used for storing large volumes of products: meat, semi-finished products, berries. Their design allows you to place large items that will not fit into standard refrigerator drawers. Temperature conditions in chests it can often drop to -24°C and below, which provides the so-called “shock” freezing, which preserves the maximum beneficial properties of the product.
| Parameter | Chest freezer | Upright freezer |
|---|---|---|
| Load type | Top | Front |
| Energy efficiency | High (cold does not go away) | Medium (cold goes away when opened) |
| Area occupancy | Large, low profile | Small, high profile |
| Ease of access | You need to bend over, the products are below | Everything is in sight, ergonomic |
☑️ Choosing a place for the freezer
Defrosting systems: drip and No Frost
Inside the freezer, one of two can be implemented main moisture removal systems. Found in older models and budget options static system. In it, moisture from the air settles on the back wall, freezes and turns into a fur coat. This type of freezer requires manual defrosting at least once every six months. The user must turn off the device, remove the food and wait for the ice to melt.
More modern models are equipped with a system No Frost (literally “without frost”). In such chambers there is a fan that drives dry cold air through special channels. The moisture settles on a hidden evaporator, which periodically heats up, and the water flows into the pan, from where it evaporates. Ice never forms in the compartment itself.
⚠️ Attention: No Frost freezers cannot store food without packaging (containers or bags). Dry circulating air will quickly dry out the surface of the food, leading to loss of weight and taste (the “freezer burn” effect).
There is also a combination system, often called Full No Frost. In it, both the refrigerator and freezer compartments operate using moisture removal technology. This saves the owner from any defrosting procedures, however, such models, as a rule, are more expensive and have a slightly smaller usable volume due to the thickness of the walls with channels.
Why does a No Frost freezer hum?
A hum or whistle in freezers with a No Frost system is often caused by the operation of the fan. If the noise level increases sharply, ice may have frozen on the blades or the fan motor bearing may have worn out. Also, the sound can be made by the refrigerant passing through the tubes, which is the norm.
Temperature conditions and markings
To understand the capabilities of your freezer, you need to know how its temperature conditions are marked. Snowflake symbols can be found on the front panel or inside the camera. One snowflake means temperatures down to -6°C, two - down to -12°C. Three snowflakes are the standard for long-term storage (-18°C). Four snowflakes (****) indicate the presence of a quick freezing function that allows you to cool a fresh product to -24°C and below, without defrosting existing stocks.
The climate class is also important. It indicates at what ambient temperature the freezer can operate. For example, class SN (subnormal) allows you to work at room temperatures from +10°C to +32°C. If you plan to install a chest freezer in an unheated garage or on a balcony, you must choose extended range models (N, ST, T), otherwise the compressor may not start or quickly fail.
Electronic control allows you to set the exact temperature in 1-degree increments. This is useful if you store specific products that require special conditions. Some models have a function Eco Modethat slightly increases the temperature (for example, up to -15°C) to save energy when the chamber is not completely filled.
- 🌡️ Class A: Consumption up to 0.3 kW/h per day (for chambers with a volume of up to 100 liters).
- 🌡️ Class A+: Consumption is 10-20% below the standard.
- 🌡️ Class A++: Consumption is 30-40% below the standard, the most economical models.
Typical faults and diagnostics
If the freezer has stopped freezing, but the light is on, you should first check thermostat or the temperature sensor. In mechanical models this is a rotary knob, in electronic models it is a sensor. A common problem is the sensor freezing, which is why the compressor “thinks” that the cold has already been reached and does not turn on.
Another common reason is a refrigerant (freon) leak. This can happen due to corrosion of the evaporator tubes or mechanical damage. Symptoms include quiet operation of the compressor (it turns on and off immediately) and lack of cold. In such cases, you need to call a technician to find the leak and refill the system.
⚠️ Attention: Never try to speed up the defrosting of the freezer by picking at the ice with a knife or other sharp object. There is a high probability of breaking through the evaporator wall, through which all the refrigerant will instantly escape. Repair in this case will not be economically feasible.
Problems with the door also affect operation. If seal (the elastic band around the perimeter) is worn out or dirty, warm, moist air will constantly flow into the chamber. This will lead to the formation of a thick ice crust and increased load on the compressor. Regularly checking the tightness of the door is a simple way to extend the life of the unit.
Is it possible to transport the freezer lying down?
Transporting the freezer in a horizontal position is highly undesirable. Oil from the compressor may leak into the refrigerant circuit, causing water hammer on first start-up. If transportation lying down is unavoidable, let the device stand upright for at least 12-24 hours before turning it on, so that the oil flows back into the compressor crankcase.
Why does the freezer hum or vibrate a lot?
Vibration is often caused by incorrect installation: the refrigerator must be strictly level, resting on all legs. If there is no distortion, but there is a humming noise, it may be due to wear on the compressor shock absorbers or the tubes getting on top of each other. In older models, a hum may be a sign of aging motor.
What is the service life of a freezer?
The average service life of a high-quality freezer is 10-15 years. The key component that determines durability is the compressor. Inverter models of modern brands (for example LG, Samsung, Bosch) often have a warranty on the compressor for up to 10-20 years, which indicates their reliability.
