Split system: what it is

Maintaining the optimum parameters of the atmosphere in homes and workplaces can be provided inexpensively. For this purpose it is necessary to make a precise choice in the study of various proposals in the thematic segment. In most situations, the best option is split-system. What is it, discussed below. In this article, there are a lot of useful information for today's pickiest consumer. It will help make the right decisions at every stage, from shopping to equipment settings to suit personal preferences.

Requirements for modern climate system, and the project as a whole

It is no accident the first posted a picture with a cheerful installer. It is well illustrated anchoring complexity external equipment unit on the outer wall surface. In some cases, it will have to seek the services of industrial climbers. Nothing to do about. It is wiser than to risk his life.

However, after finding out the general principles and design features would be easier to carry out checks. Some operations are performed indoors, so allowed some independent action. The exact cost of the project is impossible without taking into account additional costs: transportation, installation, commissioning, routine maintenance.

However, the main part of the article refers specifically to the selection. Note the general criteria to be met by high-quality contemporary climatic system level:

• maintaining the temperature with high accuracy;
• reasonable consumption of electricity;
• no unnecessary noise;
• convenient and clear controls;
• the possibility of using individual settings;
• easy to clean;
• reliability and durability.

The last point is particularly important given the complexity of access to the outdoor unit and built into the wall to repair utility lines.

This advertising poster is marked only part of the potential. Modern equipment in this category can create the premises for a favorable microclimate. It cools, heats, Cleans and dries the air. Technology should be considered in view of the enhanced functionality. Of course, do not forget about a reasonable cost.

Modern split system: what it is, the general characteristics, advantages and disadvantages

As noted above, this category of equipment is multifunctional. The trade network offer hundreds of various models with different equipment. To avoid confusion start with simple designs, common definitions.

The operating principle of a split system

With this figure will learn the basic hardware components and its functionality:

• The heated room air passed through the radiator (tube with transverse plates), which is mounted in the inner split-system unit.
• It transfers heat to the refrigerant, which in gaseous form flows through the transport pipe into the outer part. There are cooled by the same schedule.
• By reducing the temperature of the refrigerant converted into a liquid. It flows into the indoor unit, where the heat accumulates again.
• The pressure in the system provides a compressor, which is mounted in an external unit.
• Inside the set valve opening and blocking flow to move the working fluid.

Differences of a split system air conditioner from the usual

This example shows a typical single block air conditioning. There are also models that are mounted in the window opening. Their movement in service is not provided. The figure shows that all functional units are installed in a single housing. Condensate collection is a special pallet. large-diameter pipe is needed to bring the hot air out.

Pros and cons of split systems

The advantages of separate structures are shown in the following list:

• Installing the outdoor compressor can significantly reduce the noise level.
• When placing the unit with the condenser to the heat exchange efficiency is increased street.
• The resulting moisture can be removed from the system through the pipe for draining otmostku building.
• The indoor unit is not difficult to make a compact. In some embodiments, a split-systems hide it inside the building structures combined with ventilation.

It should be emphasized that the split-systems are equipped better than monoblocks. They set multistage filters. To control, settings and receipt of operational information in the standard remote controls are added. Some models can be connected to the electronic-software complexes "smart home".

It should be noted disadvantages to review was the objective:

• Installation of split systems is fraught with considerable difficulties. In addition to working at height need channels in the walls for the power cables, tubes, coolant transport routes.
• Pre-need to obtain permission of municipal authorities, if there are restrictions on changing the appearance of the facade of the building.
• In some cases it is necessary to coordinate action with the nearest neighbors.
• The cost of a split system is well equipped with higher than with a mobile device.
• Stationary equipment will not work without the high cost to move to another object in another room.

The main elements of a split system air conditioning for apartments

Functional units are connected copper tubes in which refrigerant travels. They are connected to the mains through the circuit breaker, which is selected based on the power consumption. It is recommended to use a loop grounding for security.

external power

The figure marked following typical split system components external unit:

• Radiator (1) and the fan (2), which is incorporated to enhance the heat exchange efficiency.
• The compressor (4), which creates the necessary pressure in the pipeline. To protect it from damage applied built filter solids (6).
• Four-way valve (5) installed in the models has a reverse movement of fluid. This technology is used to perform the inverse function, space heating.
• The electronics board controls the coordinated operation of block components.

The indoor unit

There is used a fan of radial type with special blades. It supplies air to a heat exchanger. Apart from simple mechanical, electrostatic and establish other filtration systems. Shutters move drive system. This allows you to direct the cooled stream in the right direction.

The main types of domestic split systems

In the study of various models take into account architectural features of your own apartment, house, office. At the same time should pay attention to personal preferences. This will simplify the selection of the optimal split-system.

wall

The compact indoor unit (1) takes up little space. Many manufacturers prefer such a neutral design so as not to hamper compliance with various interior styles. The outer part (2) and in this other embodiment is identical. It is only necessary to choose the unit suitable for power. The remote controller (3) with an infrared transmitter / receiver include cost split systems. This is reasonable, since the manual control mounted on the high-altitude technology will cause difficulties.

Note! Pay attention to the last comment, not to pay the additional component standard.

Duct

As the name implies, these internal blocks (1) are intended for mounting in the channels ventilation systems. They are supplemented by separate or built-in filters, heating devices. To display the operating parameters and settings are used like electronic components wall mount. Comfortable operation is provided by additional remotes.

When a hidden installation method are only visible aesthetic decorative lattices. Accommodation within the building structure reduces the noise level. But this option is suitable if the ceiling height is sufficient. In such devices no rotation mechanism shutters. The relatively small volume of the indoor units increases the cost. It should be noted the complexity of the service split-systems of this type.

Ceiling and cassette

These split systems are highly efficient. There are installed blinds, which feed air streams simultaneously in four directions. Acceptable use mixing mode when the blades are moved by a predetermined program up, down and sideways. The main drawback, as in the previous case, to reduce the height of ceilings.

Floor and tower

Such an embodiment, with reliable support, used for mounting heavy equipment. Indoor units of this type, if there is no speech about mobile models offer high performance. They are used to maintain comfortable conditions in large areas.

Multi-split systems

Does not necessarily limit themselves within a single structure. If desired, each room can set the original indoor unit.

Note! Components of multi split systems is better to buy one brand to provide good compatibility. In any case, the outdoor unit of a split system performance and other characteristics must conform to the terms of reference.

modifications

To reduce the difficulty in choosing here for additional versions of the equipment in this category. Some of them have improved consumer properties. Others - are better suited for specific tasks.

What is inverter split systems

In conventional equipment the compressor is turned on and off to maintain the desired temperature. Inverter technology involves sequential predobrazovanie AC to DC, then - in a high-frequency oscillations. This allows you to smoothly adjust the drive speed.

Buy inverter split system can be to quickly reduce / increase the temperature. under automatic control equipment running at peak performance to the desired parameters. After that it goes into saving mode. In addition to reducing energy costs avoided surges a shared network. This reduces the load on the connected equipment, prevents accidents, prolong the life of the individual components.

Price of inverter split systems of the type mentioned, but it is necessary to take into account the additional benefits of this choice:

• No conversion unit into an alternating current with a changed frequency, so losses are reduced.
• Field is used to create powerful magnets of rare-earth metals, which reduces electricity consumption.
• Brush contactors removed from the engine structure. In the electronic circuit does not need the control unit of the phase currents. Simplification increases the overall reliability of the external unit of a split system.

What is a split system cooling

The accommodation is set good thermal insulation, insulated doors with seals. Using the technique is maintained constantly low (around + 4 ° C) or negative temperature for a long food storage.

Is it possible to space heating using split-systems?

In the reverse direction of coolant movement obtained efficiently operating circuit. As the manufacturers claim, in some modes, it uses less energy compared to oil and other typical heaters. Individual split systems capable comparative savings of 2-3 times or more.

Do not rush to dispose of in a landfill, "antiquated" radiators. A closer examination, you can find out what are the best indicators of the universal Equipment capable of providing a narrow range of air temperatures outside (from about 0 ° C to + 6 ° C). Accordingly, the time of their application is limited transition periods off-season. They are useful in summer too cold.

However, many models are designed for a minimum value: -10 ° C. Some external units can perform the respective functions during cold to -25 ° C. The advertisements sellers focus on the best options, but modestly forget about the following disadvantages:

• In winter, the efficiency is greatly reduced, approaching the parameters of the traditional heating equipment.
• Lubricants thicken, so increases the wear of the compressor.
• Increases the risk of freezing the condensate drain pipe. This node has to be heated by a special device with additional energy consumption 20-30 watts.

How to choose a split-system

The easiest way - to take note of the official manufacturer's recommendations. simple formula can be used for independent calculations: 1 kW per 10 square meters. area at ceiling height is not more than 3 m. To prevent performance deficit during peak loads the resulting value is added to 20-25%. In more complicated algorithms, count the number window and doorsThat produce heat technology, the constant presence of people and other factors.

Note! In any case, good insulation parameters useful property.

Select the type of split systems do with all the features listed above, the individual design requirements. Especially carefully study the convenience of management, functional composition. Potential split-systems:

• Cooling, heating, draining.
• Self-cleaning technology.
• Deodorization, humidification.
• Quiet Mode the minimum speed of the indoor fan ( "Dream").
• Timer, application user settings.
• Control using wireless links Wi-Fi.

For air purification except coal and mechanical filters used ionization, photocatalytic and electrostatic devices.
