To maintain microclimatic regime in car parking docs a range of parking ventilation systems can be implemented, e.g.:
- Artificial and natural extract of fresh air
- Artificial and natural inflow hoods
- Mechanical supply and exhaust ventilation
A completely natural ventilation complex is rarely installed in car underground car lots, because such systems largely dependent on weather conditions, plus they demonstrative poor performance during peak hours, when air exchange is demanded most.
A mixed ventilation (natural and mechanical ventilation) type is commonly used on semi-open parking lots, while a completely mechanical system is mounted in covered parking facilities.
The presence of CO (or carbon monoxide) components in the air may be dangerous for the health and even lives of people. Carbon monoxide is released during the process of burning, but in the cities and parking lots in particular, the main sources of hazardous gas generation is represented by automotive internal combustion engines. Carbon monoxide is dangerous because a human cannot sense of smell it, naturally taking no take steps to leave the danger zone. CO entering the lungs rapidly enters the blood and gets in contact with the hemoglobin, whereby the oxygen transfer is blocked at the cellular level, causing asphyxiation.
The ventilation management is oftentimes automated to optimse the performance of the mechanisms. Keeping the car park ventilation system enabled permanently, even with a small number of cars parked, is a waste of money. A decent ventilation system is packed with automatic sensors and controllers, so the system can turn on the necessary component separately at any time, for example, based on the analysis of air on CO presence.
