Advantages of a split system

Why did it have to be so complicated? Indeed, in a monoblock, all these elements get along perfectly in a single case.This arrangement gives the split system a number of advantages:

Saving space in the room is one of the main advantages of split systems. The compressor block occupies a fairly large volume, but it occupies it in another room or even on the street. True, for work in the winter period, you will have to take care of additional equipment - the so-called "winter kit", with which the compressor is not afraid of even 30-40-degree frosts.

Lots of installation options. The ability to separate two split system units at a considerable distance from each other (but not more than 15-20 meters) opens up many layout options. For example, you can completely turn a utility room into a cold store by sheathing the walls with sandwich panels. It remains only to make a small hole in the wall for the cable and copper pipes, and then install the compressor outside and the fan unit inside.

The ability to bring noise and heat out. Even the most expensive and high-quality compressor makes noise during operation. And this is not very conducive to creating the right working atmosphere in the kitchen. And if you have a quiet cozy place, then the compressor rumble will reach the dining room. The output of the "noisy" part of the street - an excellent solution to this problem. Similarly, with the excessive heat that this block emits.

It should be noted that the installation of a split system is a rather complicated and time-consuming process. You will have to make various holes and recesses in the walls. In addition, a drainage sewer supply will be required to drain the condensate.

Design

The most popular type of air coolers are finned tubular models. Inside this device there are tubes inside which the refrigerant circulates. The fan directs the air flow so that it passes through the accumulation of these tubes. Upon contact with the cooled elements, the air masses lower their temperature, and a cool air stream is obtained at the outlet of the installation.

For more efficient cooling, engineers strive to maximize the area of ​​​​contact of the cooled air with the refrigerant. To do this, the tubes are equipped with fins made of heat-conducting material. With this design, the air comes into contact with the cooling elements in a larger space, which allows much faster cooling.

Tubes and ribs are attached inside the frame. This design is mounted inside the ventilation and with the help of fans it pumps cool air into the room.

Household appliances are not built into ventilation systems, they remain mobile and can be moved between rooms. These units produce cooling by taking air masses from the room and passing them through a grid of refrigerant tubes.

The best manufacturers of refrigeration split systems

Today, manufacturers offer just a huge range of air conditioners. Such a variety creates a lot of inconvenience for an unprepared buyer. Partially solve the problem by narrowing the search circle 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.

Polus engineers paid particular attention to ease of maintenance. Almost all air conditioners of this brand have an easily removable panel.

It provides full access to all internal components and systems of the unit

Brand #2 - Polar

Polair offers refrigeration air conditioners in two lines: Professionale and Standard. As is clear from the names, the first class is designed for industrial enterprises with huge storage facilities.

Split systems Standard are perfect for small shops and catering establishments. Often chosen by small business owners

The features of Polaris 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. Understand how to change the temperature regime everyone can. Split systems have elementary control and are often equipped with a remote control panel.
• Noiselessness. The entire "noisy" part of the air conditioner can be taken out into the street. As a result, it will be comfortable to be in the room.

As for the shortcomings of devices from this supplier, the restriction on the installation site is confusing. So, the distance between the outdoor and indoor units cannot be more than 5 meters.

It is also better to entrust the installation to experienced craftsmen. After all, Polair split systems usually have a complex design. Therefore, the installation itself will not work.

Brand #3 - Ariada

Ariada stands out from the competition with a wide range of low and medium temperature devices. That being said, the price of most air conditioners is more than affordable, making them a great choice for everyone.

Refrigeration split-systems from "Ariada" will cope with the freezing of products, cooling, as well as maintaining the set temperature. At the same time, the high quality of the materials used guarantees a long and trouble-free service.

The list of manufacturer's advantages should be supplemented by the fact that engineers use modern technologies in the production of blocks and components. Each model is also thoroughly tested.

Principal differences between refrigeration split systems

Such split systems consist of two blocks. The outdoor unit is placed outside the chamber. It can be located up to 50 meters away from the indoor unit, usually attached to the wall.

The indoor unit is placed inside the chamber. The blocks are connected by 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, then others can take over its functions.

Unlike air conditioners of other classes, refrigeration units are characterized by high performance and relatively low energy consumption.

To do this, they are equipped with automatic reset switches as well as an elaborate refrigerant capillary system.

The device is controlled by the built-in monitor. It supports the coordinated work of all systems and electrical components located inside the refrigeration split system.

Another important advantage of the air conditioners presented above is their protection from environmental influences and sudden voltage drops.Most models have a built-in system that protects them from exposure to high or low pressure.

Significantly extends the life of the split system, the presence of an automatic defrosting function. As a result, the housing, as well as all the components of the outdoor and indoor 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 wall of the chamber.

It consists of two parts, identical to the split system, but both parts are interconnected into one device, in a single housing.

This important difference gives them a great advantage, as it allows them to be placed in cold rooms where other units simply do not fit in height or wall thickness. The rest of the features of the two options are almost the same.

Split system selection options

Before buying a domestic air conditioner, you should compare its characteristics with the upcoming operating conditions.

It is important to determine the location of its location and the necessary functionality.

The main selection criteria include:

• constructive execution;
• compressor type;
• power;
• noise level;
• operating modes.

Also important when choosing is additional functionality, which, on the one hand, adds comfort during the operation of the equipment. On the other hand, the price tag of equipment increases significantly

Preferred system type

Based on the device, wall, window, mobile, cassette, channel splits and multi-systems are distinguished.

In everyday life, wall-mounted air conditioners are most in demand. These are traditional two-block split systems.Their advantages: affordability, compactness, quiet operation

Features of other options for climate technology:

1. Window. Easy to install, but partially block the flow of daylight. In addition, they are distinguished by more noisy operation, insufficient power for spacious rooms, limited use of curtains.
2. Mobile. Compactness and the ability to move from one room to another are the main arguments in favor of such splits. Cons: low power, noisy, the need to equip holes to remove warm air.
3. Cassette. Differ in high productivity, the hidden installation. Installation is carried out in the subceiling space, which is not always possible.
4. Channel. The installation method is similar to cassette splits, but here one unit serves several rooms. This option is suitable for private homes, offices.
5. Multi-systems. A complex of equipment from one outdoor unit and several indoor modules. The system is used if it is not possible to install an air conditioner in each room. Cons: complexity and high cost of installation.

The main disadvantage of the last three models is the complexity of installation. It is better to entrust all installation work to a specialist. And with the installation of the first three varieties, you can handle it yourself. Read on for how to do this.

Compressor type and equipment power

Split systems are equipped with a rotary or inverter compressor. The first type works according to the scheme: turning on, reaching the set temperature, turning off. Start-up cycling increases the load on the unit and the power grid.

The inverter compressor operates at different speeds, adjusting to the room temperature. Pros: quiet running, long service life, reduced energy consumption.

We talked in more detail about the principles of operation of inverter and conventional split systems in this material.

When choosing the power of the air conditioner, you must follow the rule: 1 kW per 10 square meters. m. The norm is relevant for rooms with ceilings up to 3 meters

Determining the required power of the air conditioner by the area of ​​​​the room, it is desirable to increase the indicator by a quarter in the following cases:

• the location of the room on the south side;
• an abundance of technology;
• residence of a large number of people.

The comfort of use is affected by the noise emitted by the indoor unit. The average sound indicator is 32-33 dB, which is comparable to a whisper.

Main and additional functions

It is desirable that the split could function in the following modes:

• turbo - fast heating, cooling;
• night - silent operation at reduced speeds;
• timer - the ability to select the start or shutdown time;
• auto - equipment adjusts the intensity of work to the microclimate.

Additional, practical functions include self-diagnosis of problems. The unit with the help of light and sound indication will tell the user in which area the failure occurred.

A handy feature is the motion sensor. The air conditioner switches to standby mode when activity decreases - this contributes to economical energy consumption

It is advisable to provide a system against the accumulation of ice on the outdoor unit

This is especially important if the air conditioner is planned to be used in winter to heat the air.

ballu bse-09hn1

The list of the best is headed by a modern two-component system with the Combo2 function.This is filtration with the addition of catechin, vitamins C and ozone-safe freon R410. These components allow you to purify the air through circulation.

The technique has an advantage that distinguishes it from other similar ones: micro-adjustment of temperature without sudden transitions significantly reduces energy consumption by 30-35%. The Bse-09hn1 model is equipped with an auto-restart, which helps to set the time and mode of operation in advance.

pros

• Quality build.
• Beautiful design.

Minuses

No.

In conclusion about industrial premises

The above aggregated calculation is not suitable for industrial buildings due to the inconsistency specific thermal characteristic q different types of building structures. Although the methodology proposed by SNiP is also based on the summation of all heat inputs.

The algorithm for determining the refrigeration capacity for air conditioning a production facility looks like this:

1. Determine the amount of heat flow through external enclosures by calculating the thermal resistance of the walls, roof and floor. The methodology is described in detail in the publication on the calculation of the heat load on heating - from the point of view of heat engineering, there is no difference.
2. Find out the number of personnel, calculate heat generation from office equipment and people depending on the intensity of work.
3. Sum up the heat output of all electric motors and other equipment, taking into account the simultaneity and frequency of switching on.
4. If hot technological tanks, furnaces or parts are located in the workshops, it will be necessary to determine the amount of heat flow from heated surfaces.
5. Find out the amount of supply air supplied by ventilation units, calculate the energy consumption for its cooling.

The air conditioning of some industrial premises (server rooms, large offices, cafes) is easier to calculate - there are less heat gains. The master installer will tell about this technique in his video.
