Correct setting the temperature in refrigeration equipment is a fundamental condition for long-term preservation of food freshness and safe operation of the compressor. Many users often wonder how exactly to configure Biryusa refrigeratorso that it works efficiently, without creating excessive noise and without wasting excess electricity. Errors in the settings can lead to spoilage of food or the formation of excessive amounts of ice, which will require defrosting.
Modern models, such as Biryusa 133, Biryusa 134 or Biryusa 135, are equipped with various control systems, from mechanical rotary knobs to electronic displays. Understanding how your device works is the first step to proper operation. In this article we will analyze in detail all the nuances of adjusting the climate inside the chambers.
First, you need to determine the type of control installed on your unit. The sequence of actions and available ones depend on this. Regardless of the model, the basic principles of thermoregulation remain similar, however, there are important features that cannot be ignored during the initial setup. freezing modes. Regardless of the model, the basic principles of thermoregulation remain similar, but there are important features that cannot be ignored during the initial setup.
The principle of operation of the thermostat in different models
The main element responsible for the climate in the chamber is thermostat (thermostat). Classic Biryusa models, such as the series 632 or 131, use a mechanical control system. It is a rotary knob located inside the refrigerator compartment, usually in the upper right corner or on the ceiling.
Rotating the knob changes the tension of the bellows or the position of the bimetallic plate, which leads to the opening or closing of the electrical circuit. When the temperature reaches the set value, the circuit opens and compressor turns off. The higher the number on the scale, the lower the temperature inside should be. It is important to understand that the numbers on the scale are not degrees Celsius, but standard units of cooling power.
- 🧊 Minimum value (1 or Min) - the compressor works rarely, the temperature in the chamber is high (about +8...+10°C).
- 🌡️ Average value (2-3) — optimal mode for everyday food storage (+3...+5°C).
- ❄️ Maximum value (4-5 or Max) —intensive cooling, the compressor works almost non-stop.
⚠️ Attention: Never set the thermostat knob to the maximum value (Max) for continuous operation. This leads to overheating of the motor, freezing of the evaporator and a reduction in the service life of the seals.
In more modern models with a system No Frost or improved insulation, such as Biryusa 138 or Biryusa 139, more complex control circuits can be used, but the principle is “higher number - colder” is saved. If you have just turned on the refrigerator after transportation, let it stand for 3-4 hours before setting it up so that the oil in the compressor flows into the crankcase.
Optimal temperature conditions for storage
To ensure food safety products must be maintained within strictly defined temperature ranges. In the refrigeration chamber, the optimal range is considered to be from +2°C to +5°C. Under such conditions, most bacteria slow down their vital activity, but the food does not freeze.
In the freezer, regardless of the model Biryusa, the temperature should not be higher -18°C. This is a standard value that allows you to store meat, fish and semi-finished products for several months without loss of taste. If you plan to store supplies for more than six months, it is recommended to reduce the temperature to -24°C.
| Product type | Recommended zone | Temperature range | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat/fish | Lower shelf (freshness zone) | 0...+2°C | 1-2 days |
| Dairy products | Middle shelves | +2...+4°C | 3-5 days |
| Ready meals | Top shelves | +3...+5°C | 2-3 days |
| Vegetables/Fruits | Boxes below | +5...+8°C | up to 7 days |
The distribution of cold inside the chamber Turk is uneven if a multi-flow system is not used. It is better to store perishable foods on the coldest shelves (usually the top ones, closer to the back wall). The door is the warmest place, suitable for sauces, drinks and eggs, but not for milk.
Instructions: how to set up a mechanical thermostat
Setting the temperature in models with mechanical control, for example Biryusa 8 or Biryusa 118does not require complex tools. You only need access to the inner chamber and perhaps a thermometer for accurate calibration. The process takes only a few minutes.
First, find the regulator. In most cases, this is a round pen with numbers from 1 to 5 (or 7). Turn it to the “0” or “Off” position to turn off the cooling, then return it to the middle position. This is a standard starting point for most household conditions.
☑️ Setting up a mechanical thermostat
If you notice that the food on the top shelf is starting to freeze, and on the bottom, on the contrary, it is too warm, try changing the thermostat position down one notch. Remember that changing the settings does not take effect instantly. Stabilization of the temperature in chambers with a volume of more than 200 liters it can take up to 24 hours.
In winter, when the room is cool, minor adjustments may be required. If the refrigerator is on an unheated porch or garage, the standard thermostat may not turn on the compressor because it “seems” to be cold anyway. For such cases, some models provide winter mode or a separate switch.
Electronic display control and Super Freeze
Electronically controlled models, such as some versions Biryusa 133 K or Biryusa 135, allow you to set the temperature with an accuracy of a degree. The control panel is usually located on the outside of the door or inside in a visible place.
To change the parameters, you must press the settings button (often indicated as Temp or the image of a thermometer). After this, the digital value will start flashing. Use the "+" and "-" buttons to select the desired value. Confirmation of the choice usually occurs automatically after a few seconds of inactivity or by pressing the same button.
The function Super Freeze (Super Freeze) deserves special attention. This mode is designed for quick freezing of fresh food. When activated, the compressor runs continuously, ignoring the thermostat readings, until you manually turn off the function or until the cycle specified by the program has passed (usually 24-48 hours).
- ❄️ Activation: Press the button
Super FreezeorS.F.on the panel. - ⏳ Duration: It is recommended to use no more than 2-3 days in a row.
- 🛑 Shutdown: In older models you need to turn it off manually, in new ones - automatic return after 24-50 hours.
⚠️ Attention: Long-term use of the Super Freeze mode leads to a significant increase in energy consumption and compressor wear. Use this feature only when loading a large volume of fresh food.
What should I do if the display is flashing?
If the numbers on the display are flashing, this may indicate a temperature alarm. Check that the door is tightly closed. If the blinking continues for more than an hour after closing, the sensor may be faulty or there may be a refrigerant leak.
Factors affecting the temperature inside the chambers
Even if the thermostat is set correctly, the actual temperature inside Biryusa refrigerator may fluctuate. This is influenced by many external and internal factors. Understanding these nuances will help to avoid false diagnosis of malfunctions.
One of the main factors is loading the chambers. An empty refrigerator cools down faster, but it also loses cold faster when the door is opened. Full shelves act as a cold accumulator (especially if there are water bottles there), stabilizing the temperature. However, you cannot fill the refrigerator “to capacity” by blocking the ventilation holes.
The frequency of opening the door also plays a critical role. Each opening triggers an exchange of air: cold, heavy air comes out, and warm room air comes in. The compressor has to re-cool this volume. During the hot summer period, the load on equipment increases significantly.
It is also worth considering the technical condition of the seals. If the rubber on the door Biryusa 134 or another model is worn out, dirty or deformed, the seal is broken. The cold goes away, and moisture comes in, which turns into ice.
Diagnostics of problems with temperature conditions
Sometimes users are faced with a situation where the setting does not produce results. The refrigerator compartment is too warm, or, conversely, everything freezes. Before calling a technician, you should carry out independent diagnostics.
If the chamber is warm and the compressor does not turn on, check whether the thermostat is set to minimum. If the regulator is turned to maximum, and there is no cold for 5-6 hours, and the compressor is silent, the thermostat or start relay is likely to break down. If the motor hums but does not start (a click is heard), the problem may be in the compressor.
When everything in the refrigerator compartment freezes even at minimum settings, this often indicates a refrigerant (freon) leak or a blockage in the capillary system. In two-chamber models with one compressor (for example, Biryusa 130), a malfunction of the cold redistribution damper can also lead to temperature interruptions.
Why does a lot of ice form in the Biryusa refrigerator?
A lot of ice most often occurs due to a loosely closed door, frequent opening or storage of open containers with liquid. The moisture evaporates and settles on the cold walls, turning into ice. Also, the cause may be a clogged drainage hole.
How often do you need to defrost the Biryusa refrigerator?
Models with manual defrosting (drip system in the refrigerator) require defrosting 1-2 times a year. A freezer with manual defrosting must be cleared of ice when its layer reaches 5-7 mm. No Frost systems do not need defrosting.
Is it possible to put hot food in the Biryusa refrigerator?
It is strictly not recommended. Hot dishes create localized overheating, causing the thermostat to cycle the compressor for an extended period of time, which can overload it. In addition, steam from a hot product will cause abundant ice formation.
What does a flashing temperature indicator mean?
In models with electronics, flashing often signals an increase in temperature above a critical level (usually above +8°C). Check whether the door is tightly closed, the presence of products blocking the air flow, or the performance of the compressor.
Do the settings need to be changed in summer and winter?
Yes, seasonal adjustment is advisable. In the summer, in the heat, it may be necessary to increase the cooling (increase the number on the thermostat), and in the winter, in a cool room, to weaken it. However, modern models often have automatic compensation.
