Every day, we spend about 90% of our time indoors, mainly at home and in the workplace. Confined environments have a limited amount of air, which we consume with every breath. People take on average 22,000 breaths a day, processing about 12,000 litres of air through their lungs. Indoor air is up to 20 times more polluted It is important for our health to breathe air that is clean, rich in oxygen and free of the pollutants that unfortunately accumulate and concentrate in closed, stuffy rooms. As confirmed by numerous studies, indoor air can be 5 to 20 times more polluted than outdoor air. Without proper ventilation, indoor air tends to deteriorate, becoming saturated with harm

Harmful elements include ultra-fine dust, fumes, combustion gases, formaldehyde, volatile organic compounds released by chemical detergents, glues and furniture materials. Then there are pollutants of biological origin – microorganisms such as allergens, moulds, bacteria and viruses carried by aerosols – and those of physical origin such as the dreaded radon gas. 12 Particulates Main pollutants and health impacts cause eye, nose and throat irritation and breathing problems, headaches, fatigue and low concentration. Prolonged contact can lead to heart and respiratory diseases.

Flow wall-mounted HRV With wall-mounted HRV systems, installation is plug & play. Fitting requires two small 8 cm core-drilled holes in the masonry, insertion and sealing of the conduit in the masonry section, fixing the unit to the wall with pressure screws, electrical connection and positioning the external grilles. If the optional 10 cm conduit kit is used, the grilles can be installed directly from inside the house. For more details, please refer to the instruction manual. For improved air distribution and optimal acoustic comfort, the recommended installation position a central point of a wall of the room to be ventilated, as high as possible (compatibly with the minimum recommended distances) and preferably in a horizontal configuration.

ducted air distribution system. The alternative in these cases is between single alternating flow HRV systems and dual continuous flow HRV systems. Here are some aspects to consider carefully in order to make an informed choice. Point-wise HRV with single alternating flow (push-pull) Decentralised devices with single alternating cyclic flow are also called "push-pull" because of their operation which consists of two phases in which the air is alternately pushed out of and pulled into the rooms in which they are installed. In the first phase, extracted air passes through a porous ceramic regenerative recuperator, yielding its waste heat. In the following phase, cold external air travels through the ceramic element and absorbs part of the previously accumulated heat. Studies and experiments recently conducted on this category of equipment have shown that the average heat recovery efficiency is rather low, in the order of about 20%, compared to peak values measured during the very firs

t seconds of each cycle, which can reach 90%. These systems are very simple and inexpensive but they have low air intake filtration capacity. Example of point-wise singleconduit alternate single-flow HRV, also known as push-pull type 30 In addition, since they operate with two phases, one for intake and one for extraction, this category of equipment is permanently unbalanced, i.e. it alternately generates depression and over-pressure in the rooms. To overcome this drawback, the equipment must be installed in pairs with the operating cycles reversed and synchronised so that when one intakes the other extracts and vice versa, with the inevitable doubling of costs. Only by installing the two devices in this way can the effective flow rates be equal to those of a single device, with two balanced flows. Point-wise HRV with dual continuous flow This category of equipment offers more efficient and constant heat recovery efficiency, which reaches and even exceeds values of 90%. They are u

sually designed and built to correctly serve the ventilation needs of a single room or of rooms with a maximum surface area of 20 or 30 square metres, but they have the undoubted advantage of being easy to install and maintain. The most modern decentralised controlled mechanical ventilation systems are those with dual continuous flow, equipped with a high efficiency heat exchanger, preferably of the enthalpy type and with forced filtration of intake air. They are built around two electric fans of equal capacityy serving the same room, one extracting stale air and the other simultaneously taking in fresh air. The two airflows, extraction and intake, are simultaneous and pass through the heat exchanger without ever coming into contact or contaminating each other. Today's decentralised dual-flow balanced systems represent the best combination of functionality, low consumption as well as ease and economy of installation, maintenance and operation.

dequate ventilation. Indoor air pollution by chemical, physical, and biological agents affects the respiratory system, causes allergies and asthma, immune system disorders, and damages cardiovascular and nervous systems, exposed skin, and mucous membranes. Primary air quality deterioration factors Human activities indoors also produce CO2; when present in excess, it causes drowsiness (at times, pupils at their school desks appear lazy because of insufficient air renewal in the classroom). According to a study published by the universities of Harvard and Syracuse in the Environmental Health Perspectives journal, cognitive performance decreases with rising ambient CO2 levels. The abilities to use information, respond to crises and develop strategies are particularly affected. 58 And now, having to live with Covid-19 obliges us to rethink even more and redesign indoor areas where people can find themselves crowded in confined spaces. Ensuring effective air replacement and purified ai

r in school classrooms, kindergartens, hotels, offices, bars and restaurants, cinemas, and theatres is essential to counteract infection risks. Bioaerosol particles (droplets) of less than 10 microns produced by simply breathing, talking, singing, coughing or sneezing can circulate in the air for hours in enclosed spaces lacking adequate air renewal. If such droplets are emitted by positive, yet asymptomatic, individuals, they can be inhaled by others and cause infection (this applies to Covid-19 but also to ordinary seasonal influenza). In addition to health risks linked to the possible spread of pathogens, air quality also deteriorates due to factors such as fine dust, VOCs and possible underground radon gas emissions. The Italian National Institute of Health (ISS) has issued specific guidelines on the careful management of air renewal following reports drawn up by its National Indoor Pollution Study Group and recommendations published by the UNESCO Chair for Health Education and Su

stainable Development in collaboration with the Italian Society of Environmental Medicine (SIMA). However, natural ventilation by opening windows has several disadvantages: opening windows for at least 5 minutes every hour means letting in air that is very cold in winter or very hot in summer, unnecessarily dissipating energy expended for ambient heating or cooling. Furthermore, opening windows does not hinder smog, pollen and allergens that make indoor air unhealthy. The positive effects of HRV in classrooms and offices // A comfortable micro-climate, with stable temperature and properly controlled humidity, contributes to physical well-being and improves learning // The reduction of excess CO2 avoids drowsiness, fatigue and headaches, improving concentration and attention // The dispersal and extraction of volatile organic compounds, fine dust and biological pollutants (moulds) reduces the risks of allergies and respiratory problems 59 Community HRV FlowM150 Flow800

ing the button pressed completely deactivates the LEDs. Hyperventilation: airflow is boosted to the maximum for faster air renewal and forced room ventilation for short periods. Free Cooling/Free Heating: an intelligent technology that provides natural indoor cooling: if the outside air has a lower temperature than inside, the HRV suspends the heat recovery function before air is introduced into the room, thus maintaining optimal thermal conditions. This way, naturally fresh air is conveyed indoors to create a natural air conditioning effect. This technology is particularly beneficial during summer nights and between seasons when outdoor temperatures are more agreeable. Conversely, with Free Heating you can take advantage of the warmer air outside between seasons or on warm winter days.

cts of major concern for Helty. This is why we promote not only the creation of healthier and more comfortable homes and offices, but also a culture of energy saving, and this is manifested in the high performance of our products. Indeed, Helty Flow recovers up to 91% of the thermal energy that would normally be dispersed by opening windows for adequate room ventilation. This heat is then used to warm up the incoming air, thus providing significant savings on air conditioning costs, both for winter heating and summer cooling. Minimal energy consumption The enthalpy heat exchanger also recovers any latent heat contained in air humidity, thus achieving even greater savings. Furthermore, Helty Flow technology consumes less than 150 Wh per day, a quantity of electricity so low that keeping them running constantly costs less than 3 cents a day. With a Controlled Mechanical Ventilation system with high-efficiency heat recovery such as Helty Flow, optimal indoor air management is achieved, w
