Maintenance of air conditioning installations
We ensure the best air quality, safety of installations and significant savings in operating costs.
It is well known that we spend 90% of our time indoors, which for reasons of economy and safety are mechanically air-conditioned. Cleaning of air conditioning units is essential, as 50% of infectious diseases and allergies among workers are attributed to inadequate cleaning of indoor air in buildings.
Critical factors that pollute indoor air:
Particles and organisms present in the outdoor air. Particularly in cities where the atmosphere is quite polluted with particles dangerous for allergies and asthma.
Ingredients of carpets, rugs and furniture (formaldehyde).
Microbes that are shed by people themselves, especially in busy indoor environments.
Any repairs and renovations that take place within the buildings.
Biological Pollutants
The pollution of air conditioning systems by biological agents and consequently the contamination of the air of air-conditioned rooms by these agents is a serious problem for human health.
Biological factors are highly differentiated and have been the subject of extensive studies by private, governmental and international bodies.
According to the EPA, biological contaminants include bacteria, fungi, viruses, mites, insects, biological excretions, plant pollen, etc. The same report stresses that central air conditioning systems can be hotspots for the growth and spread of biological contaminants.
IAQA considers biological contaminants to be agents derived from living organisms or being living organisms themselves (e.g. viruses, bacteria, fungi, mammalian and avian antigens) that can enter the respiratory tract and cause various health effects such as allergic reactions, respiratory dysfunctions, hypersensitivities and infectious diseases.
The World Health Organisation considers that air conditioning systems can be a source of biological pollutants, especially when not properly maintained. ASHRAE, the US body with global recognition in the field of air conditioning applications, has addressed the issue of biological contaminants in indoor air in detail. ASHRAE's recent positioning specifically for the case of Legionella provides an excellent way to provide recent knowledge about the spread of a microbe through the air conditioning system.
An extensive tabular reference to the most common pathogenic species of airborne pathogens can be found at the University of Pennsylvania's Aerobiological Engineering Department on the Internet. The US Consumer Product Safety Commission has also issued a detailed report on the effects of various airborne biological contaminants on human health.
The existing legal provisions
Greek legislation includes provisions concerning the maintenance of indoor air quality at acceptable levels, in order to protect human health. The following provisions apply not only to industrial premises, where specific measures are often applied, but also to offices, hotels, restaurants, public places, etc.
Decree 307/86 on the protection of health from chemical agents.
Decree 77/93 on the protection of health from natural, chemical and biological agents.
Decree 16/1996 on the minimum safety and health requirements in workplaces.
Document Y1/oik.2393-17/5/2002 of the Public Hygiene Department of the Ministry of Health. Health on the prevention of Legionnaires' disease.
Cleaning of air conditioning units means the removal of all forms of particles and organisms, such as dust, aerobic microbes, fungi, bacteria, etc., which are deposited on the elements of the air conditioning system.
For the proper operation of an E/M installation, the first reason is its proper maintenance. Maintenance at regular intervals ensures an improvement in the quality of the incoming air, safety of the installation and significant savings in operating costs.
Our company has concluded maintenance contracts with many companies, ensuring for its customers the proper operation of air conditioning installations and their best possible performance, despite the wear and tear of time, as well as scheduled replacement of air filters in all kinds of applications.
