Indoor Air Quality Measurement

Humans spend around 90% of their lifetimes inside closed rooms, therefore its essential to have a pleasant room climate. Air quality, in particular, has a significant impact on our health and well-being. Airtight building shells may well be superior in terms of energy, but they prevent natural air exchange. However, buildings can be fully automated using appropriate ventilation systems and sensors.
The Right Room Climate is Essential
People can survive around thirty days without food, up to four days without water, but only a matter of minutes without air. The essential component of air, i.e., oxygen, is needed to burn nutrients. The brain is particularly sensitive to a lack of oxygen. In rooms without ventilation, the concentration of CO2 increases, performance drops rapidly, we are unable to concentrate, feel tired, suffer from headaches, and much more. It's not just oxygen and the air's CO2 content, which indicates a pleasant room climate. The air humidity (ideally 40-60%), air temperature, differential temperature, air ions, air quality, and air velocity are crucial for a healthy room climate.

Therefore, indoor air needs to be "clean" for our health and well-being. Belimo's solutions for the heating, ventilation, and air conditioning industry are making a vital contribution towards ensuring clean indoor air quality. Belimo's range of sensors for measuring the most critical factors affecting room climates, such as air quality, temperature, air humidity, and flow, provide superior reliability, easy installation, and seamless integration with major Building Automation Systems (BAS). Also, Belimo's Variable Air Volume (VAV) and pressure-independent control valve technology ensure a perfectly balanced air and water flow at all times, resulting in optimum comfort.

Good Air Quality for Greater Performance

The air around us comprises 21% oxygen, 78% nitrogen, 0.04% carbon dioxide (CO2), and traces of noble gases, water vapor, and pollutants. Today, one of the most important indicators of air quality in closed rooms is the CO2 value. Because humans also produce CO2 by breathing, the concentration of CO2 continually increases in closed places where people are present. An airtight building shell means that the air exchange rate falls, resulting in an increased level of harmful substances in the indoor air. The indoor air can be counteracted by regularly venting rooms or, if this isn't possible, by fitting a ventilation system. A ventilation system can also reliably remove air pollutants; it improves the air quality of rooms in which people are present over the long term. The system will run reliably and independently if spaces are equipped with sensors that deliver accurate and dependable readings over the entire life cycle of the building. BACnet and Modbus communication protocols provide superior application data access and enable easy commissioning and configuration. HVAC building automation is key to maintaining indoor air quality.
