From semi-industrial and industrial systems. A detailed description of the types of air conditioners. Connect Access Control Card

Depending on the application of the application, all air conditioners are customary to divide into three groups:

• Household air conditioners (RAC - Room Air Conditions).
• (PAC - Packages Air Conditions).
• Industrial ventilation and air conditioning systems (Unitary).

Each group includes air conditioners of various types. Their features and scope are shown in Table:

Monoblock air conditioners, split systems and multi-split systems

By constructive performance, air conditioners can be divided into the following classes.

Models of semi-industrial air conditioners are characterized by significant power. They are able to work smoothly for many days, since their internal units are more reliable than those that are included in the package of household split systems. The main task of industrial air conditioning systems is accurate maintenance of climate parameters at a given level required for this technological process or conditions for the storage of inventory-material values.

Area of \u200b\u200buse of industrial air conditioners - production of various directions, shopping areas, catering enterprises, public buildings, date centers, server, etc.

Precision air conditioning

Precision or cabinet systems of air conditioning during the full period of their operation are 100% complied with their name - they support the climate in the maintenance room on the exact (English Precision) level of the parameters that are specified. The temperature in the room where the precision air conditioner works, will correspond to the accuracy plus / minus 1 o C, the humidity is to be maintained at a given level with accuracy plus / minus 5%. Cabinet air conditioners are designed for non-stop operation during the full calendar year, provided that time and service life is timely service - over 10 years.

Externally, precision air-conditioning devices look unavoidable, compared to household models of air conditioners - however, the exquisite design of them is not required. This segment of climatic equipment is highly specialized and intended for technical premises, which have a significant amount of technological equipment - medical, hardware, telecommunications, etc. Also precision air conditioners are also used to maintain a given climate in the warehouses of museums and warehouses. They are indispensable in conditions when storage facilities need a strictly defined climate or in a small area there is a significant amount of technological equipment, which is the successful activity of which affect the temperature and humidity differences.

According to the overall construction and the principle of operation, precision air conditioners do not differ from the device of other refrigeration instruments. Depending on the model of the cabinet air conditioning systems, the cooling of the condenser is air or water. The air cooled air can enter the room in several ways, the most common flow through the air duct, located at the floor or at the top of the air conditioner. If there is a raised floor in the room, then the cooled air is sent to the subfield, and beaten by each device in need of cooling, the air-permeable grille is satisfied in the raised floor. For technical premises with a raised floor, special models of precision climatic devices are made - they are placed directly in the subfield, only air intakes come out. In floor cabinet air conditioners for preparation enters through air intakes, located on top, side or behind the device.

Among the models of precision air conditioners there are monoblock and double-block devices - the first externally resemble window monoblocks, only much larger, and the second are similar to household splits with a simplified design. The full factory equipment of cabinet air conditioners is designed for year-round use - the devices are equipped with electrotheans and air humidification system. Cooling capacity of precision climate control devices can be from seven to one hundred kilowatt, the weight of an internal (room) unit is from 200 kg. The least powerful models (7 kW) cost about half a million rubles.

Multi-gone air conditioning systems (VRV and VRF)

Split systems consisting of a common external unit and several (from two to one hundred) of internal blocks were developed in the 80s in order to expand the line of domestic climatic devices. In the late 90s, the cost of air conditioners decreased significantly, which contributed to their mass distribution - more and more street split blocks appeared on the facades of buildings, worsening the appearance of cities. Against this background, a number of city holders introduced restrictions on the number and location of the street units of air-conditioning systems on the walls of the buildings, which made it impossible to install climatic devices into each room. And then the first place the multizonal air conditioners came out, the powerful external split unit allowed to connect several indoor block hairdryers to it - multizone split systems were highlighted by manufacturers in a separate class of climate control devices.

In the lineup of multizonal air conditioners, household and semi-industrial models: the first are formed by an external unit and several internal (as four); The second is from several external blocks combined into a common section, and up to hundreds of internal blocks. The range of cooling capacity of external blocks of household VRV and VRF air conditioning systems - 5-25 kW, the power of semi-industrial models is four times higher - 22-100 kW. The calculated power of the external block (blocks) of multizone air conditioners is actually higher than indicated in the instrument passport - this is necessary to compensate for the total load generated by internal blocks during operation. The street split-block of the multizone air-conditioning system is able to withstand 40% excess of the load. The cooling capacity of internal block hairdryers is 2-18 kW.

Indoor (internal) blocks VRV and VRF climatic systems are no different from the hairdresses of ordinary household split systems - their control and the setting is carried out by the remote control, and each internal unit is connected to external independently of others. Semi-industrial models of multizone split systems can be equipped with wall, ceiling, floor, cassette, cassette, the total power of which does not exceed the power characteristics of the external split block or section of the external blocks. The unlined multizone air conditioner unit is connected to the inner blocks by means of a two-or three-pipe highway. The freon contour of two copper pipes allows one to warm up to one and cool, or cool all the serviced premises, and formed three pipes - to work to each inner block in cooling mode or heating, regardless of others.

Household models of multi-zone split systems with a 5 kW outdoor unit and two internal blocks with five kilowatts of total power on cooling are about 170000 rubles. Rates for semi-industrial multizone climate systems are determined by the complexity of constructing the freon highway, the required power characteristics of the section of external blocks and the total number of internal hairdryers, the objectives of building such systems.

Channel and roofing systems

Both types of data of climate systems are supplied to the premises of the air through the air duct channels, otherwise their device is not the same and the most noticeable difference - two split blocks at channel air conditioners and one in the roof.

Channel conditioners. Their system includes an internal block, referred to as Fan Coil, and an external - chiller. Fan coil is placed in the most remote and sound insulated part of the building (usually in the basement), as far as possible from the workplaces of personnel - the device in the included state makes loud hum. The freon highway, uniting fankyl and chiller into the air conditioning system, does not exceed the maximum length of 50 m. Air outside the building is pumped through the air duct into the fan coil, passes cleaning and temperature preparation, then sent to consumers. Chiller, exhibited outside at some distance from the building, depending on the system's working mode, serves to remove heat or cold from fan coil. Being equipped with thin air filters, the channel air conditioners are able to perform a multistage air purification, up to the elimination of mud particles into one micron.

The cooling power range of the air conditioning channels is 5-140 kW, the maximum air flow rate is 25,000 cubic meters per hour. In the line of channel air conditioners model of three types - low-pressure pressure in a system up to 50 Pa, the range, developing maximum pressure in 150 Pa, as well as high-pressure systems, with the highest pressure of 300 Pa.

Roof conditioners. The only block of roof air-conditioning systems is exhibited on the roof of the building with the help of a special frame. The air is injected into the device, cleaned and exposed to temperature preparation, then headed through branched ducts to consumption points. Such equipment can perform the ventilation of the building - supply the air purified from dust without heating or cooling.

The overall design of the roof monoblock is almost indistinguishable from the device of household monoblock air conditioners, for example, window. The difference is that these devices are much larger and powerful, their control is carried out by a complex automation complex, carefully tracking each operating operation to avoid overheating. During operation, the climatic installation is strongly heated, it is extremely necessary for unlimited air access on all sides.
Power range of roof air conditioners - 8-140 kW, air consumption - 1500-25,000 cubic meters per hour. Compared to air conditioning channel systems, the roof air conditioners are more compact, and the presence of one block and the complete absence of an external freon highway seriously simplifies the installation work - the impressive size of the channel fan coil may require a partial dismantling of the wall to carry it into the basement room.

Both air conditioning systems are installed secretly, without hanging their elements on the building facade, it is easy to cope with air intake of the entire building, capable of operating in recirculation mode (ventilation). Their disadvantages are a significant noise of installations during operation, noise in air ducts caused by air movement.

Minimize noise will allow a careful calculation of the installation site of the climate system, equipping the air ducts by sicochifers.

Cassette air conditioners

The spread of a false-brake - suspended ceiling - the promotion of engineers-designers of leading climate techniques to create an internal split block, which could be embedded in the suspended ceiling. The external block of the cassette air conditioner is not different from the device from similar blocks of other split systems, and the room block hairdryer is a cassette installed in the suspended ceiling using an independent fastening system, the front panel of which is removed by one level with the plane of the false-roll.

The cassette air conditioner is installed in the premises with the height of the ceilings more than 2.5 m, for hiding its body in space behind the suspended ceiling, it is necessary at least 250 mm distance from the plates of the plane to the plane of the real ceiling. In addition to the height of the inner block of the cassette split system, it will be important to pay attention to the power characteristics of the pump, pumping condensate from the instrument pallet - there are models with a pump, raising moisture by 400 mm height, and there are more powerful capable of pumping fluid to a height of 800 mm. Manually cassette air conditioners are usually not managed - too high are located, so they are equipped with a remote control, infrared or wired.

Cutting power of cassette split systems is directly related to the size of the inner hair dryer, their two-compact (Eurosiz) with a wall of 600 mm and with a capacity of up to 6 kW, the usual with a wall is 800 mm and a capacity of up to 15 kW. Models with a capacity of 15 kilowatt are designed for the premises, the total area of \u200b\u200bwhich is 130-150 m 2.

Air from the room for subsequent purification and temperature preparation The cassette hairdryer pumps through the air intake in the central part of the device. Air refund is carried out from two or four sides of the front panel - this is another advantage of cassette air conditioning systems, allowing you to quickly create an atmosphere with the required parameters.

Rates for cassette air conditioners are comparable with prices for other split systems with a close cooling capacity. For example, 3.5 kW model costs about 17,000 rubles.

Ceiling conditioners

The internal block hairdryer ceilings of split systems is placed under the ceiling and attached to the ceiling plane, so that the air jet from the device moves along the most hot layer of the room atmosphere, and cooling it effectively. In addition, the flowing free ceiling flow of cooled air is guaranteed not to come to the bodies of people in the room serviced by the ceiling air conditioner. Some models of ceiling split systems allow them to be installed both on the ceiling and on the wall - they are equipped with two pallets for collecting condensate (under the horizontal and vertical installation of the device).

Cooling power in ceiling climatic systems is 2.5-18 kW, respectively, the power of the model is designed to maintain the necessary parameters of the atmosphere on the area of \u200b\u200b25-180 square meters. The maximum serviced area of \u200b\u200bceiling split systems is slightly higher than in other semi-industrial models of air conditioners - due to higher air flow velocity, they are generated. Depending on the power characteristics, the width and length of the ceiling block pixels may be different, but their thickness (height) is always in the range from 180 to 250 millimeters. The cost of the least powerful model is 2.5 kW - is about 30000 rubles.

Calculated for the preparation of air in spacious premises, ceiling air conditioners are installed in the halls of large offices, in which sections of partitions do not reach the ceiling, in industrial and trading enterprises, restaurants and libraries.

In completion

In addition to the types of conditioning devices, the semi-industrial air conditioners include column split systems whose cooling capacity reaches 50 kW and is sufficient to control the climate in rooms up to 300 m 2. But since this climate technique has already been intended to be intended to return to its description, we will not.

Due to the increased performance and high reliability, semi-industrial air conditioners are in demand in the commercial sphere and everyday life. They provide a comfortable microclimate in large apartments, country houses, offices, cafes, restaurants and shops.

This type of climate machinery is different from household models in the following parameters:

• increased productivity and cooling efficiency;
• effective and volumetric filtering elements with a long service life;
• the ability to work in more "severe contaminated conditions" and with severe frosts (up to -15 and below).

High cooling capacity, characteristic of semi-industrial air conditioners (5-30 kW), allows you to cool large halls and halls. Devices are distinguished by a wide range of applications. Effective and functional semiconduction solutions provide comfort and comfort in the premises of any destination.

They are mounted in the following objects:

• offices;
• country houses;
• cottages;
• apartments;
• cottages;
• the shops;
• premises of shopping centers;
• cafe;
• restaurants;
• workshops and workshops;
• hotels.

Taking into account the characteristics and capabilities of semi-industrial air conditioners, they cost noticeably more than household models. The price of such devices is 500-5000 dollars.

Selection of semi-industrial air conditioners

The devices are selected according to the size of the room, the quality of thermal insulation and financial capabilities. Kilowatta
power is enough to efficiently cool 10 square meters of apartment. In offices, stores and other objects with high ceilings, the capacity calculation should be made taking into account the cabbage of the room.

Depending on the external block compressor device, inverter and conventional split systems differ. The first option is more preferable in household conditions: inverter air conditioners are quieter and consume less electricity. And traditional systems are completely suitable for the rest of the premises, since their prices are lower.

Types of air conditioners "Polisa"

Semi-industrial air conditioning systems are classified based on the method of placing the inner block and design features. Let's start a review of semi-industrial air conditioners with the most common category - wall-mounted systems.

Wall-mounted air conditioning systems

The most popular climate machinery for shops, cafes, offices and residential premises are up to 100 meters. The appearance and design of wall-mounted semi-industrial air conditioners are not different from household analogs. The difference is only dimensions and high power.

This type of climate machinery is distinguished by the available price and a wide selection of models. The disadvantages include relatively low power (up to 10 kW) and strict installation requirements. There are also restrictions on the length of communication between external and internal blocks. This imposes restrictions on their placement places.

Channel conditioners

The climate system intended for installation for suspended ceilings or in attic rooms. As a rule, channel semi-industrial air conditioners have a function of partial ventilation. They can take the fresh air from the street and mix into the stream.

The power of such systems is 5-25 kW, which allows you to organize the simultaneous cooling of several rooms.

For separate temperature adjustment in each of the rooms, air flows in each of the channels coming from the inner unit are adjusted by manual or electromechanical valves controlled by thermostats.

The advantages of channel semi-industrial air conditioners:

• high performance;
• fresh air is the function;
• hidden installation;
• air conditioning multiple rooms.

Lack of system:

• labor-intensive installation;
• the need to repair the ceiling after installing communications.

Cassette systems

Unlike channel air conditioners, cassette blocks are designed to be installed directly to the suspended ceilings. Only lattice cassettes remain in sight. Air is supplied to the heat exchanger through the center of the cassette, after which it returns to the room through the side blinds. There is no substitute for fresh air. Therefore, when installing cassette air conditioners, it is necessary to separately take care of the inflow of fresh air indoors.

Advantages of cassette air conditioners:

• hidden installation;
• high performance;
• attractive appearance of the lattice;
• uniform air distribution through lattice blinds.

Installation of such air conditioners requires interference in the design of the suspended ceiling.

Column air conditioners

Stationary installations are mounted on the floor of the cooled room. The devices are characterized by increased power and are designed to quickly efficiently cool the room. Collected semi-industrial air conditioners are installed in server rooms, industrial premises and large shopping centers.

Advantages:

Disadvantages:

• Large dimensions.
• Not too attractive design.
• Large weight.

The main minus column technique is that it occupies a significant useful area.

Ceiling Systems

If the attic room is absent, and there is not enough space between the suspended ceiling and the ceiling, the installation of outdoor ceiling air conditioners is relevant. They are also used in premises with plastered or plasterboard ceilings, interference in which is undesirable. An attractive design of outdoor-ceiling devices does not spoil the appearance of the room, and the functionality does not differ from cassette models.

The outdoor ceiling semi-industrial systems are mounted in two ways:

• Fastening above the floor at the wall. Cold air is directed up to not create discomfort;
• Installation under the ceiling. In this case, the air flow is directed parallel to the ceiling.

The "Anti-Square" feature available in premium-class models allows you to control airflows using blinds. This is relevant with the zoning of the room and the creation of warmer and cold regions.

Benefits:

• Installation without interference in the design of plasterboard and plastered ceilings.
• The possibility of zoning (at the top models).

The only deficiency of the outdoor ceiling systems is that they are not intended for hidden editing.

Also there are semi-industrial multispit systems with the possibility of connecting several different internal blocks to one external. Such solutions allow you to place in each room internal block, which perfectly fit into the designer concept.

The assortment presents both the classic series of semi-industrial Split systems Heavy Classic and the inverter series of Heavy DC Inverter with internal blocks of a cassette, channel, outdoor-ceiling type in a full range of power from 12 kBTU * up to 60 kBTU. Special attention, Hisense engineers paid the development of additional solutions in the field of individual and group management.

This allows you to apply this equipment on objects of different levels and to solve any tasks: from cooling server rooms before creating a comfortable air conditioning system of an office building.

Wide range of work

Thanks to the use of modern control algorithms and high-quality components of the semi-industrial Split systems Hisense all types can operate in heating mode in the extended outer temperature range.

Highly efficient compressors

In all models of semi-industrial Hisense air conditioners, only highly efficient compressors (rotary type and scroll) are used specifically designed for use in professional equipment.

Increased track length and height difference

The use of professional class compressors, systems of trapping oil and an adaptive operational control system made it possible to increase the length of the track and the difference in height between the inner and outer blocks. This gives greater flexibility when installing semi-industrial air conditioning systems Hisense.

Divided into two boards management system and control with duplication of functions

More reliable control: With the help of a Dual PCB Control, the control system reads all performance without the slightest delays.

This allows you to achieve optimal control, intellectual defrost, protection against breakdowns. A split control system is protected from damage or hazard associated with incorrect power connections.

Additional control system capabilities

Connect Access Control Card

This function makes it very convenient to use semi-industrial Hisense systems in rooms where you need to automatically disable the air conditioning system in the absence of people indoors. For example, apartments or rooms in hotels.

Connecting a fire system

The control system of semi-industrial systems allows you to connect smoke sensors or other devices or control systems that signal fires. When this contact is triggered, the air conditioning system will be immediately disabled.

Safe work

Semi-industrial Hisense air conditioning systems are equipped with several protection steps. One of them is the control of high and low refrigerant pressure. By controlling these parameters, the control system can stop the operation of the air conditioner in the case of an abnormal mode of operation, without allowing the accident.

Smooth soft start *
