What does air conditioning
and ventilation entail?

Property managers and owners are responsible for systematically servicing and cleaning ventilation systems because their efficiency determines indoor air quality. The equipment should meet both technical standards and hygienic standards for indoor air quality and cleanliness.

Failure to perform periodic maintenance can affect indoor air quality or jeopardize the health of property users. Dirty ventilation and air conditioning systems can be a source of indoor proliferation of unwanted bacteria, viruses and fungi.

Help FAQ

Frequently Asked Questions:

What does dry cleaning of ventilation systems entail?

Systematic cleaning of ventilation ducts is required by national construction law and EU law. It is necessary to remove any waste (dust, grease, deposits, vapor particles, etc.) that have settled in the ducts as a result of various technical and chemical processes taking place on the premises. First, the ventilation ducts are inspected to diagnose the hygienic condition of the entire system. The most common way to do this is to use mobile devices with cameras attached, which allow visual assessment of the degree of installation contamination. We also measure dust content in flowing air or on duct surfaces. Afterwards, we unclog and clean the remaining part of the system with brushing or compressed air.

What are the methods for wet cleaning ventilation systems?

After performing dry duct cleaning, wet cleaning can be additionally used for better results. One method is disinfection. The service of removing pathogenic biological substances from ventilation systems consists in fogging the ducts with appropriate chemical agents. The mist from the biocides has the right consistency to work effectively and disinfect the areas through which air flows into the ventilated rooms. After cleaning and fogging the ventilation ducts, we take some bacteriological samples to verify the quality of service.

What are advanced biocidal systems in ventilation?

Ventilation systems may additionally be equipped with specialized filters and devices that have a much greater ability to capture or neutralize pollutants, thereby improving air quality in buildings. The service of building advanced biocidal systems consists in equipping the ventilation systems with electrostatic filters, UVC lamps or UV lamps with ozone function. Various configurations of electrostatic filters, UV lamps and the ozone module are the most effective in the fight against viruses and contamination. The devices inactivate pathogenic compounds thus increasing the lifetime and effectiveness of electrostatic filters.

How do electrostatic filters work?

Electrostatic filters used in ventilation systems have a very high filtration level. They work by generating an electrostatic field. The polluted air particles are loaded with a positive electrical charge by using a high voltage capacitor. The filter element, which has a negative charge, attracts and captures the ionized particles. The purified air, after passing through the filter, is supplied to the rooms.

What is the effect of UVC lamps used in ventilation on air purity?

UVC lamps used in ventilation systems emit radiation beams that neutralize bacteria, viruses and fungi present in the air. UVC radiation with a wavelength of 250-265 nm is the most effective. This type of radiation changes the structure and protein conformation in living organisms. Consequently, this leads to a change in the DNA structure of microorganisms, thus destroying any pathogens. The lamps are installed in the ventilation duct in the supply air stream - which is why they can remove as many pollutants present in the room as possible. Properly installed lamps in the ventilation system are at a safe distance from people using the premises and thus do not affect the human body in any way. They generate effective radiation at a distance of about 1m, so they should be installed in such a way as to cover the entire cross-section of the air stream with radiation.

How to use ozone in ventilation systems?

To achieve an even better effect of air purification from pathogens, UV lamps with an additional ozone module are installed in ventilation systems. Ozone is a very strong oxidant and has substantial ability to neutralize viruses and bacteria. It can also remove all kinds of organic and inorganic odors. An additional ozone module permanently installed in the installation definitely improves the quality of the air supplied to the rooms. However, excessive amounts of ozone are harmful to people, so it is important that the power of ozone generators is properly matched to the cubic capacity of the facility and the air flow rate, and that they are only activated when the ventilation systems are running.
