Indoor air quality (IAQ) and its effect on occupant well-being and comfort are essential. Many issues such as sick building syndrome, indoor air quality thermal comfort, visual comfort, and acoustic comfort are a part of the indoor environment. Good indoor air quality requires attention to the building's HVAC system, measure and monitoring, healthy indoor air, air filtration, and pollutant source management. Some good practices in these areas have also been highlighted.
On average, we spend approximately 90% of our lives indoors and take about 20,000 breaths a day. We assume the air is "clean" in the buildings and will not affect our health. It is surprising how little we know about the importance of indoor air quality.
The new 22ADP-584A and the 22ADP-584B duct differential pressure sensors with true auto-zero functionality provide precise pressure measurement. The automatic calibration electronically adjusts the transmitter’s zero reference value every ten minutes. During the adjustment, the output and display values will freeze to the last measured value, eliminating output signal drift due to thermal, electronic, or mechanical effects. The device returns to its normal measuring mode after the one-second calibration process.
Belimo is excited to announce the release of new Room Sensors, which complement the existing sensor product range. The Belimo Room Sensors measure temperature, humidity, and CO₂ in a wall-mounted design offering high accuracy and fast response. The sensors are maintenance-free and provide long-term reliability for a comfortable room environment. Integrated with Near Field Communication (NFC) allows for fast programming, commissioning, and troubleshooting with the Belimo Assistant App and a smartphone. The product series consists of Temperature, Temperature with Setpoint, Temperature and Humidity, and Temperature, Humidity, and CO2. Key features include
People spend approximately 90 percent of their time indoors and breathe 3170 gallons (12,000 liters) of air per day. Therefore, it is essential to understand the powerful influence that indoor air quality has on our well-being, especially during this extraordinary COVID-19 pandemic. While the impact of volatile organic compounds (VOCs) on humans has been widely discussed within the context of the 'sick building syndrome,' the role dry air plays in spreading of microbes, including viruses, is often neglected. High performing HVAC systems and proper humidification strategies are required to maintain a stable and healthy indoor air quality in buildings.
