Society is increasingly aware of the need to ventilate to prevent the spread of disease and to maintain the comfort of spaces where we spend long hours (living room, bedroom, living rooms) but also where we need good hygiene conditions and that in turn, they are usually wet areas (kitchens, bathrooms, changing rooms and gyms).
Both single-family homes and apartment blocks must have means so that their enclosures can be adequately ventilated, eliminating the pollutants that usually occur during normal use and providing a sufficient flow of outside air to ensure the extraction of contaminated or stale air.
In homes, the use of controlled mechanical ventilation (VMC), both self-regulating, hygrosensitive and double-flow, is especially relevant. Its objective is to guarantee the indoor air quality of buildings (both single-family homes and in the tertiary sector) without losing comfort and achieve maximum energy savings. Ventilation is a very good solution to avoid the appearance of viruses, humidity, mold and respiratory diseases.
Among the fans and accessories necessary for ventilation in a home and that Casals can offer you are:
The calculation of the extraction flow for a single-family house will be based on the number of wet rooms (bathrooms and kitchen) and the dry ones (living room or dining room and bedrooms). The CTE (spanish technical building code) establishes minimum flows in the basic HS Health document (modified in June 2017).
