A consequence of the application of large amounts of outside air ventilation and heating systems of buildings and constructions of airports cannot be a reduction, but rather an increase in the risk of negative effects of pollutants. As one of the solutions to air quality problems in these areas are invited to use the gas filtering systems.
The volume of cargo transportation by air transport has steadily increased (from 40 to 100% per year). However, this type of cargo is not completely safe for the environment. The main objective is to minimize the airline harmful effects on the environment and, in particular, the noise level. In the US, hygienic air conditions in the rooms set the standard ASHRAE 62 – 1989.
However, to meet the requirements of this standard with the help of ventilation to the outside air quality and meet regulatory requirements. Recent studies have shown that the highest level of contamination found on the leeward areas of the airport, the departure and arrival halls and ticket offices.
Thus, when it is required to increase the quality of indoor air, the use of large amounts of outside air can increase rather than reduce the risk to human health. In the design of ventilation systems at airports must be considered as the level of outdoor air pollution, and harmful substances released indoors.
