To ensure full functionality and high-quality operation of the structure, it is important to understand what temperature should be in refrigeration units. The point is that for storage different types products are provided various conditions, in particular:
- sausages, meat, confectionery cream products - from +2 to +6 degrees;
- fish (salted, preserved, cold smoked) - from zero to minus eight degrees.
How to adjust refrigerated display cases
Factory settings, as a rule, do not meet the requirements necessary in each individual case. Unlike other cooling systems, they require adjustment. This factor is associated with the need to place certain products that require special conditions. How to set up a refrigerated display case is indicated in the operating instructions, but often there are nuances that distinguish real actions from those described. Based on this, a person who has not previously encountered this type of activity and does not have experience is recommended to use the services of professional adjusters. If the connection and operating conditions are incorrect, the product will deteriorate, and the enterprise or store will suffer significant losses.
Adjustment usually occurs after installation and connection of the equipment and is carried out by setting parameters on the control unit, which in most models is located closer to the bottom of the chamber. If it is damaged, the operating cycles (on/off) are disrupted. Consequently, the regime also goes astray. For adjustments, special panels or remote controls are often used. This is only possible if the system is fully operational.
Before you begin setting up the installation, you need to check the voltage level. To avoid surges, it is advisable to install a voltage stabilizer.
Today, the refrigerator is the main household appliance in most families. Without it there will be no proper work delicious food, no family harmony. One of the most important factors in this sense is properly adjusted temperature. The more complex the technique, the more varied the settings and the greater the likelihood of making a mistake. How to avoid troubles and keep food fresh and healthy in the refrigerator?
If the temperature in the refrigerator is not set correctly
Most perishable foods stay fresh the longest at temperatures from +2 to +5. If the temperature control in the refrigerator is turned up too much, the food freezes, losing beneficial properties. After defrosting, it quickly becomes unusable - you have to cook it in a hurry. If the refrigerator is too warm, bacteria begin to actively multiply in the food: fruits and vegetables rot, sausage and cheese become moldy, and juices begin to ferment.
Even more serious high temperature affects frozen foods. A faulty temperature sensor in the freezer will turn fish or meat into a foul-smelling mass in a few hours.
Add to this the constant leakage of melted ice, as well as excess energy consumption, and it becomes clear why it is so important to properly regulate the temperature in the refrigerator. Unfortunately, not everyone even knows what the minimum and maximum operating temperatures are for the model in their kitchen. They turn the handle - it doesn’t freeze on the walls, it doesn’t drip into the pan - and thank God. How to do it right?
Optimal temperature in the refrigerator

Since the refrigerator compartment usually has a decent volume, heat is distributed unevenly throughout it. Much depends on where exactly the compressor is located and how the refrigeration unit is structurally designed. For some models, the cold zone is located closer to the top of the body, for others - in the middle part. The closer to the point of entry of cold air, the lower the temperature. To decide how to properly distribute food in the refrigerator compartment, let’s pay attention to the following facts:
At temperatures from +1 to +3 It is best to store meat, fish, chicken eggs, hard cheese, mayonnaise in open packaging.
At temperatures from +2 to +4 Sausages and culinary products, soft cheeses are preserved longer.
At temperatures from +3 to +5 store soups boiled vegetables, dairy products, bread.
For seafood, the most comfortable temperature is from +4 to +6 degrees. Fruits (with the exception of exotic ones - bananas, pineapples, etc., which are generally undesirable to store in the refrigerator) should be placed in the warmest place of the refrigerator compartment, where the thermometer shows +6...+8 degrees.
Based on this, you can roughly estimate how the food set will be distributed according to your refrigerator model.
As for the freezer, don’t forget: frozen foods are stored equally at -18 degrees and at -25°C. Therefore, it is not at all necessary to chase the freezing power.
Adjusting the refrigerator temperature

Oddly enough, most people don’t even look at the instructions before plugging in the refrigerator and adjust the temperature by randomly rotating the thermostat (in the case of electronic temperature control via an LCD display on expensive models, this procedure is still more correct). At the same time, it is not always possible to produce accurate and correct setting. However, there are “folk” methods of control. Instead of trying to interpret arbitrary numbers on switches, it is better to check the air temperature with an outdoor thermometer. Place it in a glass of water, which you place in the center of the refrigerator. Check the temperature after a few hours. If it is higher than +4 degrees, feel free to turn the regulator towards cooling. If lower than 2-3 degrees, turn it in the opposite direction. Once you have stabilized the temperature within 3-4 degrees, place the thermometer between bags of frozen food in the freezer and wait a few hours. If the temperature is below -25°C, turn the temperature control up, if above -18°C, turn it down to lower the temperature.
How to regulate the temperature in different brands of refrigerators?

In modern units, it is possible to regulate the temperature of the freezer and refrigerator compartments separately, as well as of different compartments independently of each other. Let's look at the features of thermal regulation of models from leading manufacturers presented on the domestic market:
- Gorenje— the temperature in the refrigerator is set by turning the regulator knob to a position between Max And Min. It is recommended to set the thermostat to position ECO. If the air temperature in the room where the refrigerator is installed is below 16 degrees, the manufacturer advises to unscrew the handle Max, and in the surrounding heat - vice versa.
- Liebherr- electronic temperature control, in many models - separate regulation in the refrigerator and freezer compartments. There is a mode CoolPlus- a system that protects the refrigerator from temperature changes in the external environment. As soon as the air in the room becomes colder, the compressor of the device begins to work intermittently. SmartFreeze- a special cooling technology in which, due to active air circulation, it becomes possible to quickly freeze many kilograms of food at once. Super cooling and super fast freezing modes in the freezer.
- Atlant— the temperature is regulated by turning the thermostat knob in both directions. There is a dial on it. The adjustment occurs on a seven-point scale: 0 - the compressor is turned off, 1 - the highest temperature, 7 - the lowest.
- Samsung— the temperature is regulated using the control panel separately for the freezer and refrigerator compartments:
- refrigerator: press the Fridge button to set the desired temperature in the range from +1 to +7 degrees. The default temperature is 3 degrees;
- freezer: a The temperature is set logically from -14 to -25 degrees. An accelerated freezing function is available, which is activated for 72 hours, after which the freezer returns to normal temperature conditions.
- Bosch— the temperature is regulated similarly to the previous brand, there is also a super-cooling mode, available for 6 hours (the temperature quickly and evenly drops to +2 degrees, cooling the products just put in the refrigerator - as a result, those lying next to them do not have time to thaw).
- Indesit— the temperature inside the refrigerator is automatically adjusted in accordance with the position of the thermostat knob: 1 - the warmest mode, 5 - the coldest mode.
- LG- in many models, the temperature is controlled using the control panel separately for the freezer and refrigerator compartments.
Stinol— there are two independent regulators for a two-chamber unit. Five positions on both thermostats, super cooling mode available in the freezer.
How to identify incorrect temperature control in the refrigerator?
Most often, it manifests itself either in the form of a crust of snow and ice growing on the walls of the appliance (in addition to the unaesthetic appearance, “hypothermia” also increases the energy consumption of the refrigerator), or in the form of a puddle flowing into the pan, or even spilling onto the floor. Food begins to spoil faster than usual or loses moisture and dries out in one to two days. An unpleasant odor wafts through the refrigerator compartment. If you notice these symptoms, think about it: maybe it’s just that you didn’t take the time to read the instructions?
Refrigerated display cases, unlike classic refrigerators and chests, require adjustment of the temperature and operating mode. This is due to the fact that completely different products that require different temperatures. To learn how to set up your refrigerated display case, read the instruction manual.
For meat and fish it is usually set to -2 degrees, for cakes and pastries +7, for vegetables and fruits +8 or more. Also, a lot depends on the humidity in the room and in the display case itself. A properly adjusted and configured refrigerated display case allows products not to lose their presentation for several days, does not weather them, and does not itself become covered with drizzle and condensation.
Remember that refrigerated display cases are intended for temporary storage of products. This means that the goods in it should be changed regularly, and unsold items should be sent to cabinets or chests for storage. Some devices, such as Cryspi freezer display cases, allow you to lower the temperature to -8 degrees during non-working hours, which significantly extends the shelf life of goods. But more often than not, such a function is the exception, not the rule.
How to adjust the temperature in a refrigerated display case
Refrigeration equipment is complex system, which should be set up and maintained by a professional. General information instructions for setting the temperature are in the operating instructions. Be sure to read it before you begin. If something is unclear to you, it is better to contact a specialist - this will help avoid further expensive repairs.
Temperature setting and display programming occurs via the control unit. It is usually located at the bottom of the display case on the seller's side. Majority modern models configured via the remote control - you can set the operating temperature and operating modes from it. Setting up via the block requires qualification. Determine what temperature should be in your display case and set it from the remote control. The display case has its own thermometer, which shows the current temperature - the software and physical ones must match.
There are often cases when the actual and programmed temperatures differ from each other. This situation occurs due to contamination of the heat exchanger: it becomes covered with ice, dust, various debris and grease. It is necessary to monitor its cleanliness and do “general cleaning” of the display case at least once a month. Ariada freezer display cases have an automatic defrosting system - you need to connect a special drainage to them for proper operation. Other display cases simply need to be unplugged and washed with warm water and soda.
How to set the temperature in a refrigerated display case
The initial temperature adjustment will be carried out by a specially trained person after installation of the display case. Consult him about this process - usually there is nothing complicated about it. Raising and lowering the temperature from the remote control is generally done using one button (like the volume on a TV). Setting the temperature through the block is more difficult, since any error can lead to the program being reset. Also, the settings may be lost if there is a power outage while you are changing the program. In such cases, you will have to call a professional to completely reprogram the device.
How to lower the temperature in a refrigerated display case
Sometimes situations arise when the temperature in the display case does not drop to the required level. Why is this happening? There can be many reasons - a damaged compressor, low pressure or refrigerant leak, the heat exchanger becoming clogged with ice or dirt, curtains that are not tightly closed. If the temperature does not drop to the required level, then defrost the display case, wash the heat exchanger thoroughly, remove dust from the external compressor, and clean the grooves along which the curtains run. If this does not help, then reduce the temperature via the remote control by a few degrees and see if it decreases in the display case. If yes, then just leave it as is. If not, call a specialist.
Installing refrigeration equipment of any kind is a complex and responsible process. There are many factors to consider when installing a refrigerated display case.
Basically, showcases differ in temperature conditions, features of cooling systems (refrigerants used), dimensions and external design. On modern enterprises trade and catering use low-temperature or medium-temperature refrigerated display cases. The choice of equipment of one category or another is carried out in accordance with the characteristics of the goods sold and the specifics of the enterprise’s activities.
Refrigerated display cases can be equipped with built-in and remote cooling systems. The need to install equipment with remote and built-in refrigeration is determined not only by the size of the room, but also by sales volumes. Showcases with built-in cooling systems are most often equipped with small retail outlets, and remote refrigeration is used when there is a significant amount of space.
Where should you not install a refrigerated display case?
Before installing a refrigerated display case, carefully study the possible restrictions.
Firstly, refrigerated display cases should never be installed near heat sources. In this case, we mean not only heating radiators, but also natural sources of light and heat - the sun's rays, which are not recommended to be allowed to directly hit the display case.
Secondly, the refrigerated display case should be located in an area of the retail outlet where the likelihood of drafts is minimal.
Thirdly, refrigerated display cases should not be placed close to walls or on uneven floors. Moreover, when loading products, you should pay attention to ensure that the display case does not swing.
Failure to comply with the specified rules for installing a refrigerated display case can lead to an increase in energy consumption, a decrease in the efficiency of the equipment, and a reduction in service life.
Features of setting up refrigerated display cases.
Refrigerated display cases differ not only in design, but also in operating features. It is recommended to check the compliance of the temperature regime and adjust the refrigeration units at least once a month.
The impact of many negative factors can lead not only to a decrease in the efficiency of the refrigerated display case, but also to its premature failure. To avoid this, the heat exchanger should be checked regularly. The refrigerated display case must be clean: dirt, dust, debris, fluff must be removed as it accumulates on the fins of the heat exchanger.
You can install a refrigerated display case either independently or with the help of a specialist. In any case, the first adjustment of refrigeration equipment must be done very carefully, preferably under the supervision of a professional.
Strict adherence to instructions and regulations is a mandatory factor for the effective and durable operation of a refrigerated display case.
Before directly installing the equipment, you must check the power supply. The mains voltage must be uninterrupted. Any failures and voltage surges will have a negative impact on the operation of the display case and will also lead to its breakdown. The equipment is configured using a special remote control or by adjusting the electronic control unit. Experts also recommend equipping refrigerated display cases with a system for automatically recording and regulating temperature and humidity conditions.
A special category of refrigerated display cases is equipment designed for selling and displaying products outside retail premises. Such display cases should be installed with special attention to compliance with all operating rules.
Correspondence between the type of refrigeration display and its installation location.
Refrigerated display cases are divided into several categories depending on the installation method.
Island refrigerated display cases are equipment that is installed in the center of a retail space. Access to the displayed goods is provided from all sides of the display case.
Wall display cases are installed directly along the walls of the room; the products in them are viewed from only one side.
A special category of display cases is refrigeration equipment for displaying products in retail outlets with a self-service system. Such display cases can be either open or closed. The main point of installing such equipment is to provide customers with access to them for independent selection of goods.
You can obtain additional information about the features of installing refrigerated display cases from consultants on the “Refrigerated Display Cases” website. Experienced specialists will give you valuable recommendations and answer all your questions. With the help of professionals, you can choose the best refrigeration equipment options for your business.
A refrigeration unit is a system that requires monthly inspection, adjustment, and serious maintenance. After all, one single mistake can cost more than just calling a technician.
Features of the refrigeration unit
Each refrigeration unit has its own characteristics, mode and equipment. But if you have no other choice, and you decide to install the unit yourself, you will definitely need:
- professional consultation;
- instructions;
- control unit.
Refrigerated display cases have specific design features that are significantly influenced by various factors: dirt, debris and dust. Therefore, the space near the display case between the ribs after some time becomes clogged with dust and dirt, which causes the device to fail.
To prevent this from happening, you must strictly follow the instructions for this device. There are instructions for use, as well as for setting up refrigeration chambers. Experts recommend following them carefully: all points of the instructions must be completed in the correct order, according to the document. It is better to carry out the first setup with a professional or under his clear guidance. Read the instructions carefully and make notes for yourself.
Refrigeration electronics
The electronics unit of a refrigeration unit is very important, because its smooth operation depends on it. The block is located under the bottom (on the left) of the installation. Maintaining the temperature in the refrigerated display case depends on it, turning off and turning on the refrigeration unit in a timely manner. Now they can be controlled and configured using a remote control, which is usually included with the kit. Without a remote control, adjust the refrigerator compartment by adjusting the block.
The electronic unit of the refrigerated display case is configured at the factory. Standard modes are installed there. Self-adjustment is necessary when it is important to set the temperature of the refrigerated display case in accordance with the conditions for storing goods and the climate. If the refrigerated display case is intended for storing cheeses and sausages, you need to increase the frequency and duration of defrosting. This way the evaporator will not become clogged with snow.
Remember, when starting the setup, check the voltage in the network, because its fluctuations can undo all your efforts - then you will no longer be able to do without a specialist.
Setting up a refrigerated display case yourself is a very responsible and painstaking job that requires high professionalism, clarity and increased attention in the work.
