Split system for a refrigerator: types + nuances of calculation and selection of the necessary equipment
The importance of such an element as a split system for a refrigerator cannot be underestimated.This is the main element, the core of the refrigerator, which plays the role of maintaining a constant temperature.
Split systems are used in medium-sized thermally insulated chambers, ideal for storing products in production.
Next, we will talk about the features of refrigeration split systems, give advice on choosing suitable equipment, and also name the best manufacturers of such equipment.

Fundamental differences between split refrigeration systems
Such split systems consist of two blocks. The external node is located outside the chamber. It can be located at a distance of up to 50 meters from the indoor unit, usually attached to the wall.
The indoor unit is placed inside the chamber. The blocks are connected using copper tubes, and their connection is provided by a power cable. You can read more about installing split systems in this material.
Also on the market you can find a number of models of refrigeration units that are paired with two or more compressors. Due to their reliability, these devices are ideal for production. After all, if one compressor fails, others can take over its functions.
Unlike air conditioners of other classes, refrigeration units are characterized by high performance and fairly low energy consumption.
To achieve this, they are equipped with automatic restart switches as well as a carefully designed capillary system for the refrigerant.
Another important advantage of the air conditioners presented above is their protection from environmental influences and sudden voltage changes. Most models have a built-in system that protects them from exposure to high or low pressure.
The presence of an automatic defrosting function significantly extends the service life of the split system. As a result, the housing, as well as all components of the external and internal units, are reliably protected from the negative effects of ice.
In addition to separate (split) systems, refrigeration monoblocks are popular. This is a fully equipped device that is installed on the chamber wall.
It consists of two parts, identical to a split system, but both parts are interconnected into one device, in a single housing.
This important difference gives them a great advantage, since it allows them to be placed in refrigeration chambers where other units simply do not fit in height or wall thickness. The remaining features of the two options are almost the same.
Types of climate control equipment
It is important to correctly determine the temperature level. Today, manufacturers offer two variations: medium-temperature and low-temperature split systems.Each of them has its own purpose, as well as a number of features.
Features of medium-temperature units
The main task of this class is to maintain the room temperature in the range from +10 to -5 degrees Celsius. Typically, medium temperature air conditioners are used to cool food. For example, such systems can be found in wine cellars.
Devices of this type are divided into three subcategories:
- the first - can lower the temperature down to -5 degrees;
- the second - supports + 10;
- the third - cools the room to zero.
As for functionality, medium-temperature split systems are equipped with an electric defrosting system and can also automatically maintain a user-specified temperature.
Pros and cons of low temperature air conditioners
Low temperature refrigeration units are purchased for freezers. They help freeze any food and maintain temperatures between -5 and -35 degrees Celsius.
A standard low-temperature split system consists of two components: a compressor-condensing unit and an evaporator. Their body is most often made of stainless steel, which is coated with a layer of polymer for additional protection.
Speaking about the advantages of the air conditioners presented above, we should especially highlight:
- compactness — thoughtful design allows you to save space inside the refrigerator;
- efficiency — manufacturers managed to achieve high device performance with extremely low power consumption;
- noiselessness — low-temperature split systems during operation produce a sound no higher than 40-50 dB. Therefore, they can be installed without problems even in residential buildings;
- safety — the devices have a built-in alarm system.
The complete set of freezer air conditioners usually includes a scroll, screw or piston type compressor, two types of filters (dryer and suction), a condenser, a pressure switch, and a liquid receiver.
The box may also contain solenoid or thermostatic valves, as well as one or more air coolers.
Recommendations for choosing the right equipment
The complexity of choosing split systems for industrial use cannot be compared with buying an air conditioner for home use.
Indeed, in this case, you need to make the right decision and choose equipment for servicing huge premises. In order not to make a mistake with the choice, we will look at the main technical characteristics.
Device size and power calculation
Before purchasing a refrigeration air conditioner, a summary table is usually compiled. It contains all possible information about the operating conditions of the device.
For example, the document indicates the temperature range for storing certain products, the necessary additional functions, the volume of the storage chamber and the climatic conditions of the region.
Drawing up a summary table helps to avoid unnecessary costs and extremely complex refrigerator design. Thanks to it, you can calculate the desired power of the device.
If you don’t want to create a table, then online calculators will help you calculate the power. There are a huge number of them on the Internet.
To obtain the recommended value, you will only need to indicate the area of the room, ceiling height, degree of illumination, and the number of other household appliances.
Functionality and equipment of climate control equipment
The most common additional option for refrigeration units is a remote control panel. This engineering solution can significantly simplify operation. You will not need to go into the storage room to change the device settings.
In addition to the main components - compressor and air-cooling units - the device is supplied with connecting heat-insulated copper tubes.
The kit may include wires, all the necessary installation for hanging blocks, soldering tubes, and tools for refilling with freon.
The best manufacturers of refrigeration split systems
Today, manufacturers offer simply a huge range of air conditioners. Such diversity creates a lot of inconvenience for an unprepared buyer.The problem will be partially solved by narrowing the search to devices only from the most reliable and trusted suppliers.
Brand #1 – Polus
If you need to order an inexpensive refrigeration split system, then choose the Polus brand. These are relatively cheap units that show good power, and their service life is calculated in decades.
Brand #2 – Polair
Polair company offers refrigeration air conditioners in two lines: Professionale And Standard. As is already clear from the names, the first class is intended for industrial enterprises with huge warehouses.
The features of Polair devices are as follows:
- High build quality. The manufacturer uses only first-class stainless steel, aluminum, and connecting tubes are made exclusively of copper.
- Simplicity. Anyone can figure out how to change the temperature regime. Split systems have basic controls and are often equipped with a remote control panel.
- Silence. The entire “noisy” part of the air conditioner can be taken outside. As a result, it will be comfortable to be in the room.
As for the shortcomings of devices from this supplier, the limitation on the installation location is confusing. So, the distance between the external and internal blocks cannot be more than 5 meters.
It is also better to entrust installation to experienced craftsmen.After all, Polair split systems usually have a complex design. Therefore, you won’t be able to handle the installation yourself.
Brand #3 – Ariada
The Ariada company stands out among competitors with a wide range of low and medium temperature devices. At the same time, the price of most air conditioners is more than affordable, which makes them an excellent choice for everyone.
The list of manufacturer advantages should be supplemented by the fact that engineers use modern technologies in the production of blocks and components. Each model also undergoes rigorous testing.
