In our previous post we talked about Controlled Mechanical Ventilation, a system that, by avoiding the opening of windows and thanks to the heat recovery system, is much more efficient than traditional ventilation. However, in both cases we are faced with the same questions: how do we know when it is necessary to ventilate, how often and for how long do we need to ventilate a closed room?
The need for air renewal in a space will depend on its air quality, which can be measured by various indicators: indoor and outdoor temperature, relative humidity, CO₂ concentration , volatile organic compounds, formaldehyde or airborne particles, among others. Thanks to the measurement of these parameters we can have an objective reference of the ventilation needs.
This is how Demand Controlled Ventilation (DCV) systems work, a technology capable of providing people occupying a building with the right amount of air flow needed at any given moment and automatically.
This regulation is achieved by integrating a sensor (or series of sensors) that continuously measure various parameters that condition the indoor environment, such as those mentioned above. The sensor output is applied to a control system that adjusts the outdoor air flow rate through the ventilation system according to the level of demand detected, thus ensuring that good air qualityis continuously maintained in an effective and efficientmanner.
The main advantage of integrating this technology into Controlled Mechanical Ventilation systems is that the end user does not have to worry about programming: it is an intelligent automatic system that adapts to real needs.
Demand Controlled Ventilation therefore offers multiple benefits:
Thus, effective DCV systems combined with air quality monitors can achieve significant energy and cost savings while ensuring a healthy indoor environment.
Our MICA devices continuously measure the main parameters that condition indoor air quality and can be easily integrated into HVAC systems to ensure not only efficient and effective ventilation, but also guarantee high levels of health and comfort automatically.
