Maintain indoor climate by ensuring that the specified parameters is possible by means of a complex of means, united under the title "air conditioning system".Modern air conditioning systems are very diverse technical characteristics and performance variance.The general purpose is to: create and maintain the necessary air parameters (list parameters depends on the variety of systems, among others can be noted 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.

  2. power (household and commercial).By
  3. device (multizone, precision, systems chiller-fan coil, central, roof, Cabinet).

comfort and technological system - Identify the difference ↑

comfort air conditioning system designed to create and maintain the conditions necessary microclimate in the premises.Such systems are household and commercial.There is no clear demarcation, just in everyday life, as a rule, use the air conditioner at the performance.

details on household air conditioners ↑

Domestic air conditioners are one and multi-block.In single unit air conditioners all components are assembled in a single package.Examples are window and cell models.The multi-block system is arranged in 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 cables.

Multi-split system
powerful outdoor unit multi-split system allows operation of several indoor units

advantage of the single-block units is easy installation does not require highly skilled third-party assistance and the main drawback - high noise operation.Installation of air conditioning on the basis of split systems is much expensive, requires the participation of experts with high-tech equipment.As for the features of work: split system virtually silent, their cooling capacity is several times higher than the power consumption.

Timely maintenance of air conditioning systems of this type (clean or replace the filters of the indoor unit, the outdoor unit to protect from freezing 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 apartment or cottage is done by installing a split system required power.Commercial air-conditioners with high productivity, it is also a kind of split-systems.Depending on how the device of the indoor unit distinguish channel, cassette, ceiling and columns.Features

technological systems ↑

Technological conditioning system provide optimum 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 materials (e.g., in the food industry, various laboratories), maintaining the relative humidity in the designated part (e.g., to eliminate the possibility of static electricity when working with explosive atmospheres).

Multizone air conditioning facilities
particularly useful application of multizone systems in buildings where you want air conditioning facilities with varying degrees of thermal stress.

multizone air conditioning system provides simultaneous multiple service 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.) Is also possible simultaneous operation of various units in 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 the building of any architectural complexity.

Introduction to Precision air conditioning ↑

In conditions that require great precision to meet the required parameters of the microclimate necessary precision air conditioning.We are talking about a continuous clock security and maintenance of air purity required humidity, temperature (up to 1 degree).

example, precision air-conditioning system ensures uninterrupted operation of data center equipment, mobile operators and pharmaceutical laboratories.Air Conditioning, guaranteeing high accuracy performance microclimate typically diblock contains an external condenser unit and fan in the internal automation system, humidifier, air compressor, an evaporator and a fan.Air can deliver this type of air through the bottom panel (through the raised floor air distribution space).

Air conditioning chiller-fan coils ↑

system is fundamentally different from the others using antifreeze or water as a coolant for heat exchange interconnect.

operation of the system chiller-fan coils
In this system, the distance between the air-conditioning units can reach up to 50m in height

Chiller - is the outdoor unit system, a refrigerator cooling water that is supplied by insulated pipelines to fan coil units.Water circulation system used for the pumping station.Fancoils purpose and device resembles indoor units of split systems, installed inside the serviced apartments contain a heat exchanger, fan, filter and control unit.

Advantages of

  • maximum distance between the units and the number of fan coil units is practically unlimited, depends on the capacity of the pumping station and the performance of the unit used;
  • no need to use costly copper lines, they may be steel or PVC;
  • range of power produced by chillers 5-9000 kW, which allows you to use these systems to carry out air conditioning cottages, apartment buildings or industrial premises.

features central air conditioning systems ↑

central air-conditioning system - a multifunctional complex is located in a separate room of the building or in a separate building, design air-conditioning in this case there is still at the design stage of the building.Each project is in addition to the air search for the optimal technical solution, includes a circuit design of the ventilation system and the layout of the air conditioning system.

obvious that the air conditioning in closed concert halls or stadiums is made by means of more powerful devices than those made to apply to maintain the microclimate in the usual cottage or city apartment.Only a responsible approach at the stage of system design, the purchase of all the components, installation and sound operation ensures high efficiency of the air conditioning system.
