This article we will explain what an exhaust fan is and its implication in ventilation systems, indoor air quality and people's health. The CTE (Technical Building Code) decrees that homes must have a ventilation system (hybrid or mechanical) so that air circulates from dry to humid rooms. To do this, intake openings must be provided in the living rooms, dining rooms and bedrooms, and extraction openings in the toilets, kitchens and bathrooms. The purpose is to ensure appropriate ventilation throughout the home, thanks to the supply of sufficient ventilation flow to guarantee the extraction of contaminated air from inside the rooms . The air extractor and current regulations The air extractor plays a fundamental role in the ventilation process, since it is the device responsible for locally expelling the contaminants that are produced as a result of normal and habitual use. To ensure proper functioning of the ventilation system and not put people's health
Rsk, it is essential to take into account the criteria dictated by current regulations. The CTE DB HS 3, Indoor Air Quality establishes the following requirements regarding its design, dimensioning and maintenance operations. Design: They must be arranged in accessible places for sanitation. They will be connected to extraction ducts at a distance from the ceiling of not less than 20 cm Chinese Overseas Africa Number Data and at a distance from any corner of not less than 10 cm. Dimensioned: They must be sized according to the extracted flow and for a depression that compensates for the expected pressure losses. The total surface area of the extraction openings in each room must be the largest of the products of the following statements: 4 × qv or 4 × qve (where qv = minimum required ventilation flow rate (15 l/s in bathrooms) [l /s] and qve = ventilation flow rate corresponding to each extraction opening of the enclosure [l/s]). Maintenance operations: Cleaning operations: once a year. Condition review: 1 time every 5 years. Types of extractors Extractors can be classified based on the movement of the air flow: Axial or helical : the air flow has the same direction as the axis. Centrifugal : the air flow has the same direction as the spokes. H
Elicocentrifugal : the air flow enters in the axial direction and leaves in the radial direction. Beyond current regulations: the air extractor on the market If you want to guarantee optimal ventilation that ensures quality indoor air for you and yours, it is important to take into account the following recommendations: Installation of an extractor that has self-regulating technology . This will allow for a constant ventilation flow rate, regardless of the depression. Installation of hygro-regulatable vents . This will make it possible to vary the ventilation flow depending on the relative humidity. Installation of a stato-mechanical air extractor (for hybrid ventilation). This will allow ventilation to be carried out as in natural ventilation when conditions are favorable and as in mechanical ventilation when pressure and ambient temperature conditions are not favorable.
