Types of air conditioning filters: coal, air, plasma

Modern air conditioners not only provide a comfortable temperature in the room, but also improve air quality. To do this, they are equipped with a wide variety of filters: plasma, coal, air, catechin and silver. Air conditioners with air filters are equipped with fine or coarse cleaning systems. The mesh grill under the front panel delays large particles entering the air stream - wool, fluff. Smaller particles of dust remain on the thin filter. This is the minimum kit that all modern devices are equipped with. Premium models contain multi-stage filtering mechanisms.

The industry produces filter elements that are placed temporarily to protect the compressor. If necessary, they are removed or replaced. These are anti-acid cleaners in the loop system where freon circulates.
Some elements of household split systems do not change throughout the life of the air conditioner; others are subject to regular replacement or periodic cleaning of accumulated debris and dust.

Air filtration system in ducted air conditioner

Duct air conditioner filter

For fancoils and channel models, there are different types of filters that are cleaned according to a certain technique. The principle of operation of the channel system is different from the domestic one. Sometimes, along with air conditioning, ventilation functions and takes air from the street.

Maintenance of filters for ducted air conditioners is one of the most difficult types of activities, since cleaning elements that are not always included with the equipment are ordered separately. There are situations when the installation is done by a team that does not fulfill the requirements, and it is simply impossible to get the filter after installation. Over time, it becomes clogged and renders the fan unusable, which is why the climate system ceases to fulfill its functions.

The filter for duct air conditioner is installed on the air intake side. So it is more convenient to get, change or clean. If the filtration is located under the ceiling, during installation it is necessary to provide access for inspection and cleaning.

Plasma Air Filtration

The plasma filter in the air conditioner is designed for rooms where gas impurities and odors are constantly present. They are installed in the kitchen to absorb odors after cooking, while smoking rooms eliminate the smell of tobacco. In rooms where animals live, the filter will eliminate characteristic odors. In addition to the deodorizing effect, it reduces the amount of allergens in the air.

The principle of operation of the plasma filter is based on the effect of high voltage on living organisms that enter it: fungal spores, microbes and viruses, as well as plant pollen. Larger suspensions are deposited on the photocatalytic filter preceding the plasma.

30 minutes is enough for two-thirds of harmful impurities from the air to remain on the surface of the filter.

The manufacturer recommends changing the cartridge once every 5 months, but craftsmen learned how to clean it efficiently - they soak it for 15 minutes in warm water. If the contamination is very strong, add detergent. Then dried in the sun and exploited.

Antibacterial air purification system

Expensive air conditioners are equipped with a multi-stage air purification system

The antibacterial filter for the air conditioner destroys pathogens, preventing them from multiplying in the humid environment of the indoor unit. The coating has a different origin:

  • Vegetable - wasabi is a new development in which a plant is used that is similar in characteristics to domestic horseradish.
  • Filters with silver ions.
  • Catechin coating, which is also made from plant components. Filters developed by Panasonic. Catechin is an antiseptic secreted from the foliage of certain plants. It destroys most of the known viruses, microbes. Six hours is enough to completely neutralize any kind of viruses in the room.
  • Charcoal filter. It is a plate filled with activated carbon. Passing through such an obstacle, the air is cleaned of all harmful impurities and odors. Charcoal filters must be changed at least once every 5 months.
  • Photocatalytic coating. A type of air conditioner with a carbon filter. Absorbs unpleasant odors. It is restored under ultraviolet rays in a few hours, so it does not require replacement.
  • UV cleaning based on the principle of sunlight. Used as an extra for the destruction of pathogens. Removes about 87% of bacteria and viruses.
  • A biofilter with special enzymes that break down microorganisms before they begin to multiply.

Most of the filter elements are designed for a short life, as the natural components quickly exhaust their life. Many experts question many functions, for example, a filter with vitamin C.

The fine plasma air conditioner filter “Cold Plasma” is an innovation in the field of climate technology. Allows you to completely destroy the microorganisms in the room, turning them into water. The effect is achieved over the entire area of ​​the room, not only in the area of ​​the filter.

Anti-acid compressor protection split systems

An anti-acid filter for the air conditioner is necessary in the event of a compressor failure due to the destruction of its main components. The amount of acid in the refrigerant increases, which affects the composition of the oil and freon. This is due to the presence of air, dirt or moisture in the system, as well as to the low level of refrigerant in the loop system.

After replacing the compressor and cleaning the freon, two filters are installed - one in the line where the refrigerant circulates, the other in the suction line. For some time, the degree of contamination of the filter elements is checked. If necessary, replaced by new ones. If the air conditioner line is cleaned of acid residues, the core is removed or the anti-acid element is replaced with a conventional dehumidification filter.

Benefits of using antioxidants

  • cost savings, as old oil and refrigerant do not merge;
  • compressor protection against corrosion;
  • removal of acid from the circulating fluid occurs within two days;
  • no drainage of the line with nitrogen is required;
  • easy installation.

The diameter of the antacid filter element is wide enough not to increase the rate of passage of the refrigerant through it, so the pressure in the system does not change. They are installed in any position, the direction of fluid flow for ease of installation is indicated by arrows. The housing is coated with a powder paint that is resistant to corrosion.

Anti-acid filter device

Activated aluminum is the main substance that the core consists of. It is used as an adsorbent and occupies 70% of the volume. The remaining 30% is a net substance that traps both acids and residual moisture.

On the one hand, there is a grid to contain solid particles that have fallen into the liquid or formed during the chemical reaction.

Two valves, located on both sides of the device, are designed to periodically measure the pressure at the inlet and outlet of the filter to assess the degree of contamination and the need for replacement.

Copper fittings allow soldering to introduce a cleaning device into the line.

Acid devices of various modifications are designed to work with different types of refrigerants. Depending on the amount of coolant in the system, the volume of the device is selected - from 125 to 1000 cubic centimeters.

A sophisticated filter system in a domestic air conditioner requires more thorough care, but helps to achieve air features that are completely safe for health. The ability to install additional filtering elements is specified when purchasing equipment.
