Gazelle refrigerator: how it works and works - detailed analysis

Refrigerators Gazelle are domestic equipment that gained popularity due to its simplicity of design, reliability and adaptation to Russian operating conditions. These units are often found in domestic and commercial settings, from apartments to small shops. But how exactly do they work? How are they different from imported analogues? And why do some models continue to serve well for decades?

In this article we will look at operating principle of the Gazelle refrigerator from refrigerant circulation to the features of thermoregulation. You will learn which parts are responsible for cooling, how to recognize malfunctions by the sound or behavior of the equipment, and why some models Gazelle require specific care. The material will be useful for both owners and those who plan to buy a used unit or are engaged in repairs themselves.

Design of the Gazelle refrigerator: main components and their functions

The basis of any refrigerator Gazelle is classic compression cooling system, but with some features characteristic of domestic production. Let's consider the key components:

• 🔧 Compressor —the “heart” of the system, which pumps refrigerant through the circuit. Models Gazelle often installed domestically produced piston compressors (for example, DXM-3 or DXM-5), known for their maintainability.
• ❄️ Evaporator is a metal grid inside the chamber where the refrigerant boils and takes away heat. In older models, the evaporator could freeze over with ice, which required regular defrosting.
• 🔄 Condenser - a coil on the back wall where the refrigerant is cooled and condensed. In Gazelle it is often open (without protection), which simplifies cleaning, but increases the risk of damage.
• 📉 Thermostat - mechanical or electronic temperature controller. Early models used simple bimetallic thermostats (TAM-133), which over time could “lie” by 2–3°C.
• 💨 Fan is not present in all models. In units with a system No Frost (for example, Gazelle-160), the fan distributes cold air, preventing icing.

Feature Gazelles — use of R12 or R134a refrigerant depending on the year of manufacture.. Old models (before the 2000s) worked on R12which is now prohibited due to harm to the ozone layer. Modern analogues are converted to R134a or R600a (isobutane), but during repairs it is important to take into account the compatibility of oils and seals.

Operation principle: how the Gazelle refrigerator creates cold

The operation of a refrigerator Gazelle is based on Carnot cycle a physical process in which the refrigerant consistently changes its state, taking heat from the chamber and releasing it outside. Let's look at the process step by step:

1. Refrigerant compression: The compressor sucks gaseous refrigerant from the evaporator and compresses it to high pressure (5–10 atm), heating it to 70–90°C.
2. Condensation: Hot gas enters the condenser (coil on the back wall), where it is cooled by the room air and turns into liquid.
3. Expansion: Liquid refrigerant passes through capillary tube (thin channel), where its pressure drops sharply and the temperature drops to -15...-30°C.
4. Evaporation: Cold refrigerant enters the evaporator (inside the chamber), where it boils, absorbing heat from the air. The cycle repeats.

In models Gazelle c manual defrosting the evaporator is covered with frost, which eventually turns into ice. This worsens heat transfer, so the unit requires shutdown once every 1–2 months. In versions with No Frost the fan evenly distributes the cold, and the heating element periodically defrosts the evaporator (the cycle takes 10–15 minutes).

Temperature conditions and their adjustment

Refrigerators Gazelle are equipped with mechanical or electronic thermostats that allow you to set the temperature in the range from +2°C to +8°C (in freezer - up to -18°C). However, actual values may differ due to:

• 🌡️ Room temperatures: If the room is hotter than +30°C, the compressor will work almost non-stop, which will increase energy consumption.
• 🚪 Door opening frequencies: Every time you open it, it gets into the chamber warm air, and the thermostat gives a command to cool.
• 🍖 Quantities of products: A loaded refrigerator takes longer to cool. In Gazelle with a weak compressor, this can lead to insufficient frost.

To adjust the temperature:

1. Turn the thermostat knob (usually located inside the chamber or on the top panel).
2. In mechanical models Gazelle the scale is often indicated by numbers from 1 to 7, where 1 is the most warm, and 7 - the coldest.
3. To check, use an outdoor thermometer: place it in a glass of water on the middle shelf for 12 hours.

Typical malfunctions and their symptoms

Refrigerators Gazelle, especially those produced in the 1990–2000s, have characteristic “diseases” associated with wear of parts or factory features. Let's look at the most common problems:

• 🔊 Constant hum of the compressor: If the unit does not turn off, there may be a refrigerant leak, a clogged capillary tube, or a thermostat failure. In models Gazelle-140 the starting relay often fails.
• ❄️ Freezing of the rear wall: In drip models this is the norm, but if the ice grows in a thick layer (more than 5 mm), check door seal or defrosting system.
• 💦 Water under the refrigerator: The reason is a clogged drainage hole or a crack in the condensate collection container. B Gazelle Drainage is often located in an inconvenient place, which makes cleaning difficult.
• 🔥 The compressor does not start: Check surge filter, start relay i thermal fuse. In older models, the contacts may have oxidized.

Check the voltage in the socket (there should be 220–230 V)|Inspect the door seal for cracks|Listen to the compressor - it should hum quietly, without clicks|Make sure that the thermostat is not stuck in the “Off” position-->

Particular attention should be paid refrigerant. If there is less than 50% freon left in the system, the compressor will work for wear, but no cold will be produced. Signs of a leak:

• The compressor is hot, but the refrigerator does not freeze.
• Oil stains are visible on the circuit tubes (the refrigerant carries oil with it).
• After turning it off and on again, cold appears on the 10-15 minutes, then disappears.

What to do if the Gazelle refrigerator does not freeze, but the light inside is on?

This means that the problem is not in the electrics, but in the refrigeration circuit. Most likely there is a refrigerant leak or a clogged capillary tube. Self-repair is only possible if you have equipment for vacuuming and refilling. Otherwise, contact a specialist - the cost of refilling R134a freon for a Gazelle is about 3-5 thousand rubles (for 2026).

Differences between Gazelle models: what affects the operation

Over the years of production, refrigerators Gazelle have undergone several modifications that have affected for their work. Main differences:

Old models (Gazelle-106, Gazelle-120) are different simple design, but require regular maintenance: cleaning the condenser, replacing the seal and defrosting. New versions (Gazelle-Nord) are equipped protection against voltage surges and can work in garages or dachas without heating.

⚠️ Attention: Models Gazelle before 2000 could have used refrigerant R12, which is now prohibited. When repairing such refrigerators, a complete replacement of oil and freon with compatible analogs is required (R134a + oil PAG). Self-refueling without evacuation of the system will lead to repeated leakage!

Operation and care: how to extend the life of the refrigerator

Refrigerators Gazelle known for their durability, but only with proper care. Here are the key recommendations:

• 🧊 Defrosting: For models with a manual system - at least once every 2 months. Use a plastic scraper (not metal!) to remove ice.
• 🧽 Cleaning: Wipe the door seal with a weak soda solution (1 tablespoon per 1 liter of water). Clean the capacitor with a vacuum cleaner or brush 2 times a year.
• 🔌 Power supply: Connect through a voltage stabilizer (especially in rural areas). Gazelle sensitive to surges above 240 V.
• 📦 Product placement: Do not place hot dishes - this increases the load on the compressor. In the freezer, leave a gap of 2-3 cm for air circulation.

For models with No Frost important:

• Do not block the ventilation holes with food.
• Once per year, clean the drainage hole (located on the back wall of the refrigerator compartment) with a cotton swab.
• If the refrigerator is turned off for a long time (for example, at the dacha in winter), leave the door ajar to avoid mold.

⚠️ Attention: In refrigerators Gazelle with a mechanical thermostat, you cannot turn it on abruptly the handle from the maximum position to the minimum - this can cause water hammer in the compressor. Change the temperature gradually, at intervals of 10–15 minutes.

Comparison with imported analogues: pros and cons

Refrigerators Gazelle is often compared with imported brands (Atlant, Indesit, Samsung). Their key advantages:

• ✅ Maintainability: Parts (compressors, thermostats, evaporators) are easy to find on the secondary market. The price of spare parts is 2–3 times lower than for LG or Bosch.
• ✅ Adaptation to Russian conditions: Operate at a voltage of 180–240 V and temperatures up to +40°C (imported ones often turn off at +35°C).
• ✅ Simplicity of design: There are no complex electronics that are difficult to repair in the provinces.

Disadvantages:

• ❌ Energy consumption: Old models (Gazelle-106) consume 1–1.5 kW/day (class D), while modern Atlant - 0.5 kW (class A+).
• ❌ Noise: Noise level 45–50 dB (for imported ones - 38–42 dB). The compressor may “rattle” when the shock absorbers wear out.
• ❌ Design: Outdated appearance, thin shelves, lack of freshness zone.

Choice between Gazelle and an imported refrigerator depends on priorities:

• If you need reliable, cheap to repair a unit for a summer house or garage - Gazelle is ideal.
• If important silence, efficiency and modern functions (for example, super freezing) - it is better to consider Atlant or BEKO.

FAQ: Frequently asked questions about Gazelle refrigerators

Why does the Gazelle refrigerator make a loud noise during operation?

Loud noise can be caused by:

• Wear compressor shock absorbers (replacement of rubber tires is required gaskets).
• Touching condenser tubes to the body (carefully bend them with a screwdriver).
• Clogged capillary tube (refrigerant does not circulate, the compressor is running under load).

If the refrigerator Gazelle makes noise clicks - this is normal: this is how the start relay works.

Is it possible to transport the Gazelle refrigerator lying down?

Transport Gazelle in a horizontal position possiblebut with with reservations:

• After transporting lying down, you need to wait 6–8 hours before turning on (the oil from the compressor must drain).
• Place the refrigerator on its sidebut not on the door - this can damage the hinges.
• Secure the compressor (wrap it with a rope) to avoid impacts on the body.

For models with No Frost horizontal transportation is not recommended - the ventilation system can be damaged.

What refrigerant is used in the Gazelle-160?

In the model Gazelle-160 (production 2000–2010 gg.) refrigerant was installed R134a (in earlier versions - R12). Refill volume:

• Refrigerator compartment: 60–80 g.
• Freezer compartment: 100–120 g.

When refilling, use PAG 46 oil (for R134a) or mineral oil (for R12). You cannot mix oils!

Why does food spoil quickly in the Gazelle refrigerator?

Causes of food spoilage:

• Incorrect temperature (higher +5°C). Check the thermostat or seal.
• Frequent door opening (especially in hot weather).
• Clogged drainage hole - water accumulates at the bottom of the chamber, creating mold.
• In models without No Frost ice on the back wall can block air circulation.

Solution: defrost the refrigerator, clean the drainage and set the thermostat to the position 3–4.

How much does it cost to repair a compressor in a Gazelle?

The cost of repair depends on the problem:

• Replacement starter relay: 800–1,500 rubles.
• Repair compressor (oil change, cleaning): 2,000–3,500 rubles.
• Complete replacement of the compressor: 4,000–7,000 rubles. (including operation and refilling with freon).

For models older than 15 years, it is often cheaper to buy a used refrigerator than to repair an old one.
