according to national regulations, aeraulic systems must periodically undergo controls, maintenance and sanitation to protect workers’ health?

Legionellosis often represents a not considered risk in biological risk evaluation of schools, but epidemics have been discovered in environments like schools, hotels and hospitals
Security measures has been immediate for the infected rooms. These measures have been activated by a major's decree to debilitate the dangerous bacterium
Balancing analysis of aeraulic systems is Alisea’s service that checks the air flow. To guarantee that the system works properly, or that it provides the correct quantity of fresh air, the right temperature and humidity to the environment served, is necessary considering different parameters:
Very often the initial conditions of these parameters change over time. Some office spaces are designed with movable walls, so when the ambient is modified, the size and volume of the environment served change. At other times increases or reductions in staff often determine a difference in the number of people who first used a determined space.
Even invasive and unsuitable maintenance of the system can cause malfunctioning due to several factors, establishing an air circulation at a different speed from that envisaged.
Alisea analyses the balancing of the aeraulic system estimating every possible aspect of the problem. Balometers and anemometers are used to measure the air flow rate of the ducts and of the speed of air circulation, the temperature of the premises is taken with sensitive thermometers and the humidity is calculated with a hygrometer; structural analysis is also carried out on the system to check working conditions. The information collected is compared with the data used in the planning stage of the system and estimates are made according to the new needs.
