External air conditioner unit: size, installation, care. Outdoor air conditioner unit: dimensions and installation tips How much does a split system air conditioner weigh

Air conditioning has become a habit household appliance. Of the variety of air cooling devices, the most popular are split systems consisting of two units-blocks, one of which is installed outside the room, and the other is inside. The indoor unit of the air conditioner is a complex device that takes warm air out of the room and sent back chilled.

Any air conditioner functions due to the properties of liquids to release thermal energy when liquid is released and absorb heat when it evaporates.

The indoor unit is always placed indoors (usually mounted on a wall or ceiling), and the outdoor unit is taken out of it. Both blocks are interconnected by electrical wiring and copper pipeline through which freon circulates continuously during operation.

Regardless of the design and dimensions, the indoor unit of a split system must have the following components in its design:

• Compressor. Responsible for the compression of the refrigerant and its circulation in a closed circuit.
• Evaporator (heat exchanger). Freon is converted from liquid to gas in this radiator.
• Fan. Forces the air flow going to the evaporator.
• thermostatic valve. Helps reduce refrigerant pressure before the evaporator. As a rule, it is a thin, spiral-curved copper tube.
• A set of filters. Detain dust and larger fractions of debris, inevitably contained in the room air.
• Air distribution system.
• Blinds responsible for the direction of air flow.
• Temperature sensors.
• LED indicators.
• Information table.

Design indoor unit

Note! Since the indoor unit of a split system is often located at an unattainable height, the device always includes a remote control.

The external unit is simpler, and instead of the evaporator, the device has a capacitor - a unit responsible for the phase transition of freon from a gaseous state to a liquid one.

Basic requirements for brackets for installing the outdoor unit of the air conditioner:

• The bracket must be strong but not heavy and support the weight of the outdoor unit of the air conditioner. And also it must fit the diameter of the holes.
• Depending on the weight of the equipment, the brackets must have an appropriate safety margin. The minimum allowable figure is twice the weight of the outdoor unit itself.
• Meet the requirements of GOST for climate technology. The material must withstand any temperature regime and have anti-corrosion and anti-oxidation coating.

outdoor unit mounted on rectangular brackets

IN Lately All more manufacturers resorts to the manufacture of stainless steel brackets, due to the susceptibility of metal to corrosion from water on their surface.

The most common types of brackets used in the installation of air conditioners

Air conditioning contracting companies use several types of brackets. Among them are the following:

• Right angle fasteners made of welded together rectangular metal corners 2-2.5 mm thick

Rectangular brackets

Brackets of this type are characterized by ease of manufacture, which is why they are cheaper than their thicker and more durable counterparts. However, this type of fastening is not quite reliable and suitable for long-term operation, since it has a rather small margin of safety. When it vibrates, it experiences heavy load which could damage the protective seam. When the anti-corrosion coating begins to diverge, the brackets will become vulnerable to the harmful effects of water and other particles that can compromise the integrity metal structure.

• U-shaped metal fasteners connected to each other. Like the previous sample, they have a right angle of 90 degrees. The thickness of the material is 2-2.5 mm and is fastened with special bolts.

This design is more expensive than conventional rectangular brackets, but it is more reliable. Vibration extends only to the connecting element, while the load on the remaining parts of the structure remains minimal. At the same time, galvanized bolts are not subject to corrosion and oxidation. The coating of the brackets reliably resists harmful effects moisture and other atmospheric particles.

• U-shaped metal structure with an elongated body, fastened from below with an additional section of the channel. The thickness of the metal elements is 2 mm.

By the look this design seems to be the most reliable of all presented. Despite the small thickness metal elements, structures successfully withstand blocks of almost any weight. They do not deform under constant vibration, which guarantees a long service life of the brackets. The coating reliably protects the structure from negative atmospheric influences, preventing deformation, corrosion and oxidative processes in the metal.

• Rectangular design of two straight metal corners 2-2.5 mm thick

This type of brackets almost completely copies the first sample. The difference between them is that here both corners are fastened together by a connecting metal bar, which significantly strengthens the brackets, allowing them to withstand blocks of almost any weight. All elements are connected to each other with bolts. The bar facilitates the load on the fasteners, and the coating reliably prevents the occurrence of corrosion and oxidative processes due to negative impact moisture and precipitation. The connecting plate greatly simplifies the mounting of the brackets.

All of the above samples of almost any outdoor unit. The size of air conditioner brackets is traditionally about 40 centimeters long for the vertical mounting sections.

To the choice of mounting bracket outdoor unit air conditioner should be approached as responsibly as possible. First of all, make sure that the load capacity of the bracket is twice the weight of the outdoor unit. This is necessary because the ice that periodically covers the block significantly increases the weight of the equipment.

The holes on the fasteners must match the bolts and other fixtures for attaching the brackets. It is strictly not recommended to drill additional holes: this may damage protective layer elements, as well as reduce their carrying capacity, which will accelerate corrosion and oxidation processes as a result of the negative influence of moisture and precipitation. But it is also fraught with a warp or collapse of the entire structure under the weight of the weight of the external unit of the air conditioner.

And also pay attention to the anti-corrosion coating. The traditionally used enamel, although it reliably protects the metal from the negative effects of moisture and precipitation, loses its properties after a year and a half, which can contribute to the deformation and corrosion of the metal structure. More reliable is polymer coating: it penetrates deeper into the material and better protects the metal from corrosion.

Among all anti-corrosion agents, metal galvanizing is recognized as the best. Specialists guarantee that galvanized brackets will last at least ten years. The split system itself can last about the same.

Above, we have analyzed what types of brackets are and what are their main advantages. To purchase a high-quality bracket and not to miscalculate with a choice, a few practical tips will help:

• When purchasing brackets yourself, do not forget to make sure that the product itself is certified. By law, the seller is required to provide relevant documents. If the product is not certified, it is better to refrain from purchasing it - there is a possibility of counterfeit or poor-quality processing. In this case, the reliability of fixation is significantly reduced, which can lead to the collapse of the structure itself and the external unit installed on it.
• Fasteners must correspond in area to the length and width of the installed unit. Maximum permissible load should be twice as high as the mass of the block itself, which will protect the brackets from collapse when ice forms on the block itself
• Among all the same products, focus on value for money. If the unit is quite light and the vibration level is low, then regular rectangular brackets will work for you. For heavier blocks, a reinforced bottom is useful U-shaped design. Here you can be helped by a sales assistant who will tell you which type of bracket is more suitable for your air conditioner.
• How simpler product, the easier it is to install and the stronger it is. If you install the bracket yourself, then a rectangular bracket is suitable for you, whose sections are fastened together with a metal bar. Such brackets are best suited for those who place brackets alone.

Thus, almost any brackets are suitable for the outdoor unit. The higher allowable level loads, the more reliable the structure itself. With proper operation, the fasteners will serve you for at least ten years, which is comparable to the life of the split systems themselves.

Which brackets for mounting the outdoor unit of the air conditioner do you prefer?

The introduction of new technological solutions in household equipment often runs counter to practical expediency. The example of climate technology is the most indicative in this sense. So, recently the market has been actively filled with which are intended for indoor use. The features of such systems include the complete exclusion of dirty installation operations, which attracts a considerable audience of consumers. But with all the convenience of installation and further maintenance, such models are not able to approach the performance characteristics provided by the external air conditioner unit as part of a split system. Another thing is that the owners of outdoor installations have to deal with troublesome tasks, but of a different kind.

What is an outdoor unit?

The composition of the outdoor segment, which is part of the split system complex, includes a condenser, valve decoupling, pipes, filter driers and a fan. Depending on the modification and design, the internal "stuffing" may vary, but the traditional air conditioner kit with a remote unit has just such a set of elements. By the way, the most noticeable differences are observed in the so-called winter systems, which provide for the presence of special controllers for controlling the fan. Modern air conditioners also use multifunctional power switching relays. Such devices are designed for non-standard operation of the compressor in conditions of high or low temperatures. Unlike the indoor segment, the outdoor unit does not have electronic modules - its operation is completely subordinated to the mechanical function.

Block sizes

The outdoor unit is available on the market in various configurations and shapes. And although manufacturers, in order to simplify the segmentation, tend to unify the model lines, the choice of sizes is still quite wide. If we talk about average parameters, then it has a width of 770 mm, a height of 450 mm and a thickness of 245 mm. At the same time, the radius of the fan varies on average from 200 to 250 mm. Of course, there are also aggregates, the sizes of which deviate from these indicators. So, in the Mitsubishi lineup, an external air conditioning unit is almost square shape, which is 880 mm wide and 840 mm high. As for the parameters of the internal segment, they are not so impressive. Usually these are long narrow modules of medium size - 700 x 200 x 200 mm.

Choosing a place to install the unit

Usually, when choosing the optimal point for installing air conditioners outside, users are faced with the problems of combining ease of use and protection of the module. For example, the location of the block at height is the best option from the point of view of its safety, but in this case, access to the air conditioner for the purpose of maintenance becomes more difficult. A good solution would be to place the module on the wall near the window opening or loggia. At the same time, other nuances must be taken into account, including the absence of direct sunlight and permission for installation from neighbors, since a noisy unit can cause inconvenience to people living on the same level of the building.

In addition, it produces condensate, which will drip down in drops. Accordingly, you will have to negotiate with neighbors on the lower floors. In case of successful coordination of the installation site of the unit with other residents, you can proceed to direct installation operations. By the way, another condition for installing an outdoor unit is the possibility of laying communications in the wall.

Installation of the external unit of the air conditioner

When installing air conditioners, special mounting kits, which include pipes with flex, brackets with sets of fixing hardware, drainage communications, etc. The physical installation of the segment is carried out using load-bearing components that are embedded in the walls using anchor elements. At the same stage, brackets are used, the power potential of which is oriented to the mass of a particular module. Also, the installation of the external unit of the air conditioner provides for its communication connection with the internal segment. To do this, a hole of the required diameter is made in the wall, which will allow organizing, in addition to the main wiring, also a gasket vacuum pump and manometric manifold. At the final stage, a direct connection of communications between the two blocks is made.

Features of installing the indoor unit

When installing the evaporative, that is, the internal module of the air conditioning system, it is especially important to observe the correct position of the unit. This unit is usually mounted directly below ceiling surface with a slight indent. Mechanical fixation is also carried out using suitable brackets. True, in this case the weight of the equipment is not so large, which simplifies the workflow. After marking, the master installs the anchor elements and, if necessary, fastens the supporting profiles. Next, the indoor unit of the air conditioner is installed with strict observance horizontal position. Also, some models of such segments, according to the instructions, should have a slight slope towards the passage of drainage.

Maintenance and care

In normal operation, every six months, the air conditioner should be subjected to after-sales service. Most of work is carried out with the external unit, which is most prone to contamination. Specialists usually check the condition of the filters, the level of refrigerant, the operating pressure of the module route, etc. The most difficult operation is the replacement of the working fluid. The refrigerant is a chemically unsafe substance, so it is better to trust its refueling experienced craftsmen. But the care of the rest of the components is quite accessible to ordinary users. For example, the answer to the question of how to clean the external unit of an air conditioner is quite simple. First of all, it should be disassembled, after which, using a rag or a vacuum cleaner, rid the internal surfaces of the module of dust and dirt deposits. In the process of such care, external filters and heat exchangers are cleaned, which prolongs the life of the air conditioner.

Outdoor unit in multi-systems

The concept of technical implementation of a split system provides for the possibility of using several indoor modules in one complex, which are serviced by one outdoor unit. Unlike standard configurations, the external module of such a system has engineering differences. For integration into a multi-system, it is equipped with an additional thermostat, which allows you to more effectively control the settings of the fan and compressor. In turn, the indoor unit of the air conditioner acts as a source of information signals that determine the control of the outdoor module. That is, the user, using the remote control, accesses the panel of the indoor unit, and the latter, in turn, regulates the system of bypass communications on the freon line via a digital channel.

A question of price

In modern modifications, split-system air conditioners are not cheap, which is largely due to the complexity of the design. Even in the initial segment, the cost of an air conditioner with a remote unit is rarely less than 20 thousand rubles. Of course, you can find options for 15 thousand rubles. from little-known brands, but their quality is questionable by both specialists and users themselves, who often complain about problems.

Decent quality models are offered by Fujitsu, Daikin, Mitsubishi, etc. average cost air conditioner from the range of these companies varies in the range of 30-40 thousand rubles. At the same time, the most technologically advanced and productive kits can be estimated at 70-80 thousand rubles.

Conclusion

The use of air conditioners with a design that involves the installation of a remote unit causes many problems during installation and further maintenance. And this is without taking into account the difficulties in transporting equipment. These factors allow us to speak of such units as obsolete. Especially against the backdrop of the spread of mobile devices with a modest size. Nevertheless, the external unit of the air conditioner remains relevant in the market. This is explained by its high performance, functionality and safety during operation, since the main work units are located outside the living quarters. And if for domestic use you can find a low-power replacement for a split system in the form of a monoblock, then in the context of maintenance office space, public buildings and institutions multifunctional complexes are still unmatched.

Affordable quality

Traditional Mitsubishi Electric quality, inverter technology that provides a quick start-up, low power consumption and no inrush currents, a comfortable noise level, and everything described fits into acceptable prices are the characteristics of the Classic inverter series.

Where additional functions or design does not play a special role, the Classic inverter will be the best choice.

Antioxidant filter

The antioxidant filter has a catalytic active substance coating.

This substance belongs to the group of flavonoids, which reduce free radicals to chemically inactive compounds.

It is very important that active substance is a catalyst, that is, it does not participate in the reaction itself and is not consumed.

Therefore, the service life of the antioxidant filter is at least 10 years.

Typically, catalysts are applied to polypropylene fibers in the form of a film.

However, during operation, the film is quickly erased. Mitsubishi Electric engineers have incorporated antioxidant molecules into ceramic fibers, which are in turn soldered into a polypropylene mesh.

Therefore, the antioxidant filter can be washed and wiped.

Automatic damper

The horizontal air damper closes automatically when the air conditioner is turned off.

At the same time, it completely hides the air supply opening and elements of the air distribution system.

Lumped winding motor stator

The stator is characterized by the use of a lumped type winding as well as a special stator pole structure called "Poki Poki Core".

Such a winding can be laid on the core in an unfolded state.

Mitsubishi Electric's motor manufacturing process greatly improves efficiency.

Engines direct current fans

To reduce power consumption, high-efficiency non-contact DC motors are installed in the indoor and outdoor units of the air conditioners to drive the fans.

The rotor of such an engine has an external permanent magnet located on the surface of the rotor.

These motors have increased torque at low speeds, which has reduced the fan speed and reduced noise from the outdoor and outdoor units.

Pipe with internal knurling

In the manufacture of heat exchangers, a more expensive pipe with an internal knurling is used, which leads to an intensification of heat transfer and an increase in the energy efficiency of the system.

Air conditioners are always used to regulate the temperature in the rooms. They can be found in residential buildings, shops, subway cars. They are reliable "suppliers" of coolness on hot days, cooling the air around them. However, such devices can be configured as heating appliances and perform the functions of an ordinary heater, stove. In this article, we will analyze specifications conditioner BK-1500.

Air conditioner

This device is capable of supporting specific installed climatic conditions indoors or in any vehicle. Most simple models they only lower the temperature, cooling the air - these are the ones that are used in every second office on hot days.

There are more complicated models that are able to combine the functions of both cooling and raising the temperature. A heat pump is built into such units, capable of playing the role of a heater. More complex installations are equipped with filters and systems that purify the air entering the room, humidify it (for example, during a hot period), saturate it with oxygen, and can spray fragrances.

Kinds

According to their functions, as well as to the place of application, all devices can be divided as follows:

• Central- are used in large-scale premises. It could be an indoor stadium, a swimming pool or industrial enterprise, factory. For uninterrupted operation, such an air conditioner needs an external source of cold: or cold water, or freon from an external unit. If the device performs the functions of a heater, then, accordingly, for operation it needs a continuously incoming and heated hot water e.g. from the central heating system.
• precision- stand in rooms where it is necessary to maintain a strictly specified temperature. These are hospitals, kindergartens, laboratories, industries related to high-precision technologies and chemical and biological reactions, as well as factories related to military production, communications, electronic support and others. Externally, the device looks like a monoblock stuffed with a fan, a filter, a water heater and an electric heater. Capable of both cooling and heating air.
• Wine- work in rooms where wine is stored. Storage parameters must be observed very clearly: air temperature - 12 degrees, humidity - 60-70%. Only under these conditions can wine be stored for a very long period of time and not lose its taste and strength. On the contrary, a product stored in rooms with precise air control systems is considered to be more mature, better and more expensive every year.
• Autonomous air conditioning systems are systems that work with external source electricity. They can lower and raise the temperature, they function, as a rule, on freon.

If the air conditioner uses outdoor air for operation, then it is supply air, if the air is inside the room, then the unit is recirculated. Air conditioners with recuperation are models that can work both ways. Above, we disassembled the models according to the place of their use. Next, we will talk about installation methods, features of various machines, as well as the technical characteristics of the BK-1500 air conditioner and other units.

What are air conditioners?

According to the method of installation and characteristics can be divided into:

• Mobile- they do not require special assembly. There are monoblock and mobile split systems. To use monoblock air conditioners, you need to remove the hose from the room and remove warm air through it. If a split system is used, a separate block is taken out. The advantages of such air conditioners are that installation and maintenance are simplified here, but not yet detachable connections freon line. Main disadvantages: high price, large dimensions, installation restrictions
• window- consist of one block. Are established in a window or on a wall where the opening breaks. Cons: they produce a lot of noise, and also due to the reduction in area, for example, windows, the room becomes darker. Pros: low price, easy to install and maintain, very high efficiency, there is the possibility of a very long use.

• Split systems- consist of two blocks: one - indoors, and the other - outside. Blocks are interconnected copper pipes through which freon circulates. Today it is the most popular and most used type of air conditioners.
• Multi-split systems- this is almost the same as described above, but the number of indoor units can be two or more. The blocks are also interconnected by copper pipes through which freon circulates. Usually they are installed in multi-room premises or where it is necessary to ventilate strongly and continuously.

The air conditioner BK-1500 belongs to the type of window. Its description will be below. Other models of the Baku Machine-Building Plant will also be presented, in fact, where this device was produced.

BK-1500: characteristics

Next, consider the technical characteristics of the air conditioner BK-1500. IN window version all parts are assembled in one all-metal housing, and air flow occurs through a hole with a valve, which is located at the rear of the machine. The air conditioner is usually mounted in a window (in fact, that's why it is called so) or in a hole that breaks through the wall. In most air conditioners of this type, the resulting condensate does not drain to the street, but collects at the bottom of the unit, from where it is collected by special devices and dispersed over the surface of the condenser to improve heat transfer.

There is also a cyclic operation of the compressor - it periodically turns off, and then turns on again. This is to ensure that the mechanism does not overheat from continuous operation. The thermal sensor monitors the on and off. The latter is either mechanical or electronic.

Strengths

Let's call positive traits device data:

• low cost of installation or dismantling; the main thing is that there is an opening where the device will be located;
• there is no freon line, which means there will be no refrigerant leakage;
• the so-called function supply ventilation, that is, the use of outdoor air, which allows it to be constantly updated, circulating through the apparatus;
• long service life, easy to use.

But there are also weaknesses.

Let's list them:

• very noisy;
• along with the noise, it should be noted the poor thermal insulation between the parts of the same air conditioner, located in the room and outside; due to the passage of cold air through the device, experts recommend dismantling the model for the winter season;
• and you can’t install it in modern window frames, only if in advance, during manufacture, provide the necessary opening.

BK-1500

So, before us is the BK-1500 air conditioner. We will describe it below. This unit is capable of operating in two modes that are set manually: ventilation and cooling. It is installed in window opening or in a hole in the wall on a special wooden or metal frame. The apparatus is divided into two equal compartments by a stainless steel partition (usually): internal and external. This partition has small hole which is closed by a valve. This allows you to regulate the flow of fresh air into the room: open the damper - start the air. At the heart of the device: refrigeration unit, two fans (one is axial, the other is centrifugal), which have a common electric motor, as well as a control panel, which also includes a start-up device.

The centrifugal fan, which is installed in the internal compartment of the air conditioner, sucks air from the room. In parallel, he is engaged in the fact that he pumps cooled and dust-free air. That is, it works on the principle of "take-give". The fan motor turns on when the compressor starts, although it is able to turn on in the ventilation mode and when the refrigeration system is off.

Remote controller

The control panel, which has a start-protective device, is, of course, the "head" of the entire model. It monitors the start and stop, controls the operation of the air conditioner, sets the desired temperature in the room and maintains it. A stable temperature around the device saves it from excessive pressure and overload. On outside remote control is a panel with various pens and switches to control the entire operation of this unit. To date, many technical characteristics of the BK-1500 air conditioner are outdated. Consoles, motors, fans, additional devices produced back in the Soviet Union - all this wears out, despite the very good quality.

Conditioner BK 1500: instructions for use

• The device can only be connected to the mains using a plug that is inserted into a special two-pole socket with a grounding contact.
• The air conditioner can only be started using the switch knob located on the remote control.
• Before restarting, a short break is necessary so that the device does not overheat.
• The air conditioner is able to work even if the mains voltage deviates from normal values ​​(220 V) by several percent. At the same time, a temperature of about 20-30 degrees above zero is desirable.

• It is necessary to monitor the cleanliness not only on the air conditioner, but also inside it. The unit should be cleaned of accumulated dust, sand and other debris, do not block the air flow as with outside, and indoors, do not place things near the device, especially those that can be damaged under the influence of air flow. It is advisable not to stand close to a running machine in order to prevent possible colds and illnesses, since the air flow is very strong and cold. Do not open doors and windows when the air conditioner is running to prevent drafts.

Despite the fact that today the BK-1500 air conditioner is considered to be a rather outdated device, it is not difficult to find instructions for it. It describes in detail and step by step all the nuances of operation. this machine. This is not due to the fact that the unit is difficult to use, but with a very rigid tracking system at enterprises during the existence of the USSR, everything had to be clear, clear, detailed, correct.

Air conditioner BK-1500: specifications, photos, reviews

In general, reviews of such devices have always been positive. The air conditioner is easy to handle, with a lightweight system that, with even a little knowledge, you can fix yourself. Many craftsmen based on the BK 1500 created their own split systems or more powerful air conditioners. A very long service life and Soviet reliability are also noted by consumers.

The technical characteristics of the BK-1500 air conditioner are certainly inferior to the new ones, but for that time such units were "up to the mark". Perhaps, almost the main disadvantage is called big weight models.

Finally

Soviet technology has always been of high quality and has been long-playing. The designs, although bulky and large in mass, were reliable in use. This also applies to the models of the Baku plant of the USSR. In this article, we reviewed the BK-1500 air conditioner. Photos clearly show that these machines are used very actively to this day.
