Air Conditioning Systems
Maintain indoor air, providingcompliance with specified parameters is possible with the help of a set of technical means, united under the common name of "air conditioning system". Modern air conditioning systems are very diverse technical characteristics and performance of variance. The common purpose is to: create and maintain the necessary air parameters (list parameters depends on the variety of the system, among others, can be mentioned air quality, temperature, speed, relative humidity). Draw an overview of types of air conditioning systems to identify the main features of and familiarization with the technical specifications.

Classification of air conditioning systems
- By purpose (on the comfort and technology).
- On capacity (domestic and commercial).
- On the device (multizone, precision, chiller, central, roof, Cabinet).
Comfort and technology systems - Identify the difference
Comfortable air-conditioning systemdesigned to create and maintain the necessary microclimate conditions in the rooms. Such systems are household and commercial. There is no clear distinction here, just in everyday life, as a rule, used air conditioners at the performance.
Details about household air conditioners
Domestic air conditioners are one and multi-block. In single-block air-conditioning units all together in one package. An example can be window and mobile models. Multibank system constructed of two (split-system) or more (multi-split system) towers. Simple split-system consists of external and internal units. In the external unit contains a condenser, refrigerant is pumped and a fan. In the indoor unit arranged evaporator, fan and condensate collector. Both units are interconnected freon line and control wiring.
The advantage of single-block units iseasy installation does not require highly skilled third party assistance and the main drawback - high noise operation. Installation of air conditioning systems on the basis of split systems more expensive, requires the participation of experts with high-tech equipment. As for the features of work: split-system is almost silent, their cooling capacity is several times higher power consumption.
Timely maintenance of systemsThis type of conditioning (cleaning or replacing filters the indoor unit, outdoor unit protection from frost in winter) guarantee long trouble-free operation. Multi-split systems are composed of a single powerful outdoor unit and several (up to seven) inland. Such a device makes it possible to serve multiple premises at a relatively low energy consumption. The most common air conditioning an apartment or cottage is done by installing a split system the required power. Commercial air-conditioners with high productivity, it is also a kind of split systems. Depending on the method of the indoor unit are distinguished duct, cassette, ceiling, column.
Features of technological systems
Process air conditioning systemsprovide optimal conditions for the passage of technological processes and the smooth operation of the various devices. Such systems are used, if required constant temperature and moisture content of raw material (for example, in the food industry, various laboratories), maintaining the relative humidity at designated part (e.g., to eliminate the possibility of static electricity when working with explosive environments).
Multizonal conditioning systemsprovide simultaneous service of several areas. In multi-zone systems can connect up to 40 indoor units to one outside. And internal blocks can differ not only power, but also the embodiment of the (floor, wall, wall, ceiling, channel, etc.) And simultaneous operation of the various blocks in the cooling or heating. Qualitative strength of such systems is that the distance from the outer to the inner block can be up to 150 m at the same level and vertically up to 50 m, without sacrificing performance. These systems are economical and suitable for buildings of any architectural complexity.
Introduction to Precision air conditioning
In applications requiring extreme precisioncompliance with the set parameters of the microclimate necessary precision air conditioning. We are talking about a continuous round the clock security and maintenance of air purity required humidity, temperature (up to 1 degree).
For example, precision systemconditioning equipment ensures uninterrupted operation of computer centers, mobile operators and pharmaceutical laboratories. Air Conditioning, guaranteeing high precision climate indicators typically diblock contains an external condenser and fan unit, the internal automation system, humidifier, air compressor, evaporator and fan. Air-conditioning of this type can supply the air through the bottom panel (through the raised floor air distribution space).
conditioning chiller-fan coil
The system is fundamentally different from the use of other anti-freeze or water as the coolant for heat exchange interconnect.
Chiller - this outdoor unit system isa refrigerator cooling water that is supplied by insulated pipelines to the fan coil units. For the circulation of water at a pumping station used in the system. Fan coil units for the purpose and the device resemble indoor units of split systems, installed inside the serviced apartments contain a heat exchanger, fan, filter and control unit.
Advantages of the system
- the maximum distance between the units and the number of fan coils is practically unlimited, depends only on the capacity of the pumping station and used chiller performance;
- no need to use costly copper lines, they may be steel or PVC;
- range of power produced chillers 5-9000 kW, which allows you to use these systems to carry out air conditioning cottage, an apartment building or industrial premises.
Characteristics of central air conditioning systems
Central air-conditioning system - itmulti-functional complexes, placed in a separate room or in a free-standing building, design air-conditioning in this case, there is still at the design stage of the building project. Each air-conditioning project in addition to the search for optimal technical solutions, including the design of the ventilation system diagrams and location of the elements conditioning.
Obviously, in the air conditioningclosed concert halls or stadiums is made by means of more powerful devices than those that made use for climate control in the cottage or the usual city apartment. Only a responsible approach at the stage of system design, the purchase of components, installation and sound operation ensures high efficiency of the air conditioning system.
