The quality of the air in the interiors

Indoor air quality (IAQ) is a very important parameter, especially given the practical implications that pollutants and allergens can have particularly on children, who are more vulnerable because of an immune system which is not yet able to respond to external attacks adequately. Most students in Italy are exposed to particulate matter in concentrations much higher the values per cubic meter set by the WHO as a hazard threshold.

 

The increase in chronic respiratory diseases (asthma, chronic acute bronchitis) in industrialized countries even in younger people has led to a series of studies and reports that directly correlate poor air quality in school buildings with numerous diseases.

The European Federation of Allergy and Airways diseases patients' Associations (EFA) estimates that over 64 million European students and 4,5 million teachers are exposed to poor air quality effects in school buildings; for many months a year, students and teachers spend about one-third of their day at school, in a closed environment where ventilation is poor or insufficient.

Poor ventilation during lesson hours affects especially in crowded classes, where it is associated with an increase in CO2 levels and particulate matter, and does not cause chronic bronchitis and asthma only, but it also causes a considerable increase in migraine compared to air perceived to be “good”, and an increase in infections of the respiratory tract.

In some cases, students and teachers can contribute to the improvement of some aspects of the air in the classrooms with a series of “good practices,” respecting a series of measures that are somewhat trivial, but not to be overlooked.

Good habits help, but alone are not sufficient; the realization of adequate Controlled Mechanical Ventilation systems is the ideal solution to renew and purify the circulating air and always guarantee the best quality.

 

 

Recupera One-60H is a ventilation unit equipped with heat recovery unit dedicated to air renewal without energy waste, particularly suitable for individual environments where ducted systems cannot be realized.
It consists of:

- self-supporting sheet metal frame with polyethylene insulated internal structure;

- aesthetic covers with matt RAL9003 epoxy paint;

- very high efficiency polypropylene cross-flow counter-current heat exchanger;

- Brushless forward blades centrifugal fans with electronic motor and modulating control, with very high efficiency, high flow rates and low noise levels;

- F7 filters with low load losses, easily extractable by removing the side panels;

- Electric board complete with 4-speed fan management board, anti-freeze, automatic bypass (Free-Cooling operation), temperature probes and automatic reporting of dirty filters.

The unit is supplied as standard with:

- pair of external grids Ø200 mm;

- remote control panel with capacitive touch, for wall or 503 box installation, equipped with humidity sensor, air quality sensor, Wi-Fi interface for app management (coming soon).

 

Features available from the remote control panel

- On/off (from keypad or contact)

- Fan speed selection: silent/nominal/maximum (booster only by external contact)

- Auto fan speed selection: the air flow will be adjusted based on humidity, air quality detection, or both

- Humidity and air quality (IAQ) setpoint setting

- Change of season

- Brightness adjustment

- Key lock
