Nowadays, it is really important to achieve the best ventilation and air quality in work and public spaces such as industrial kitchens, hotels, hospitals or shopping centres.

By incorporating regulation and control in the ventilation system, we can create healthy and comfortable environments that are even more efficient and profitable.

Within the regulation, our main ally is the variable frequency drive. This regulates the speed of electric motors (RPM) so that the electricity reaching the motor is adjusted to the real demand of the application, reducing the energy consumption of the motor between 40 and 50%.

The use of variable frequency drives for intelligent motor control has many operational and environmental benefits, as it improves productivity, increases energy efficiency and at the same time extends the lifetime of the equipment, preventing deterioration and avoiding unexpected stops that lead to downtime. Consequently, this also translates into economic savings, as production efficiency is a direct saving in costs and working time.
Depending on the application, there are various types and models of variable frequency drives. The first parameter to take into account is the input and output voltage, which can be single-phase or three-phase. Other aspects to take into account for a correct choice of frequency converter are the power of the motor (Kw) and its degree of protection (IP).

On the other hand, measurement will help us to analyse results and, consequently, always try to constantly improve. Having equipment that measures air quality allows you to control your installations and act efficiently. A carbon dioxide (CO₂) sensor can be used to evaluate the ventilation of a room. With a CO₂ detector you can optimise ventilation, thermal comfort and ensure a healthy environment. It is recommended to use NDIR (non-dispersive infrared) devices, which have been found to be more reliable and durable. With these devices, not only do we achieve a healthier space, but also, if we know when the air needs to be renewed, we can save energy by activating the ventilation systems only when necessary.
