Ventilation and air extraction systems

Ventilation systems can be classified into two large groups: natural ventilation and mechanical ventilation. Natural ventilation is based on the pressure difference between the inside and the outside, which generates an air current through openings such as windows or grilles. Mechanical ventilation is produced by devices that drive or extract air by means of fans or extractors. Within mechanical ventilation, we can distinguish between:

• Simple mechanical ventilation: it consists of installing an extractor in a humid or contaminated area, such as the bathroom or the kitchen, which extracts the stale air to the outside. Fresh air enters through the natural openings of the building.
• Controlled mechanical ventilation: it is a more complete and efficient system, which incorporates a network of ducts that distribute the air throughout the house or premises. The air is renewed continuously and controlled, ensuring good indoor air quality. In addition, a heat recovery system can be incorporated, which uses the energy of the extracted air to preheat or pre-cool the incoming air, saving energy and improving thermal comfort.
• Hybrid mechanical ventilation: it combines natural and mechanical ventilation, adapting to climatic conditions and the needs of each moment.
