Controlled mechanical ventilation: a summary of how it works
The more that buildings become more energy efficient and insulated, the more important it is to ensure a high level of indoor air quality (IAQ), both to provide constant, healthy air renewal and to offer effective systems to control the temperature and humidity in domestic settings.
To complete efficient radiant systems for heating in winter and air conditioning in summer, you can rely on the above-mentioned controlled mechanical ventilation (CMV) systems, designed specifically to ensure high levels of hygiene and healthiness in the air, in every season.
What is controlled mechanical ventilation used for?
Continuous ventilation is essential for any building destined for domestic, commercial or business use. There can be numerous pollutants in the air. To keep the quantity of potentially harmful agents under the threshold, it is essential to frequently replace the stale indoor air with clean air from the outside.
Natural ventilation is obviously possible, but there are some clear disadvantages to it: the inability to control the flow, the generation of unwanted and harmful air currents, possible noise pollution, thermal energy loss and the inability to regulate humidity levels in the rooms.
CMV was designed to solve these problems and achieve the optimal recirculation of indoor air in closed spaces.
How does controlled mechanical ventilation work?
Controlled mechanical ventilation systems can be single-flow or dual-flow. Thanks to the use of suitable ventilators, single-flow CMV systems mechanically extract stale air from the room and direct it outside, while dual-flow CMV systems both extract the air and emit clean air into the space. In the latter, the presence of a high-performance heat exchanger allows the two opposite flows to exchange heat, ensuring maximum energy efficiency for temperature control systems, particularly radiant heating and cooling systems.
In both cold periods and the summer, dual-flow heat recovery systems make it easy to treat the air before re-emitting it into the spaces, through filtration, dehumidification, or the integration of heating or cooling systems to ensure optimal IAQ.
Advantages of CMV
A building with an effective air treatment system is a healthy building for those living in it and it will last longer, because mould, condensation and other problems will be rectified quickly.
When building designs include systems that can offer air filtration, controlled ventilation, free-cooling, dehumidification and heat recovery, combined with radiant temperature control systems, they will have an advanced system that aims to ensure maximum comfort and energy efficiency.
