Improving air quality in commercial and public buildings
Honeywell has expanded its Healthy Buildings Air Quality offering to help improve and measure indoor air quality with the new Honeywell Electronic Air Cleaners (EACs) with UV Systems (pictured), and a new range of indoor air quality (IAQ) sensors.
The company explained: “Honeywell EACs with UV help remove impurities from the air, and provide filtration and disinfection, without significantly impeding air flow.” The new IAQ sensors include Honeywell’s Particulate Matter Sensor PM2.5, Total Volatile Organic Compound (TVOC) Sensor and All-in-One IAQ Sensor.
Manish Sharma, Vice-President and chief technology officer, Honeywell Building Technologies, said: “We’re talking to hundreds of customers right now and working with them to update their building systems to better protect occupants. It doesn’t always have to mean ripping out old equipment and starting from scratch. It can be a straightforward HVAC upgrade with modifications that address specific concerns and minimise potential side-effects. Sensing technology is an important tool to identify opportunities for adjustments.”
Honeywell EACs use an electric charge to help remove solid and liquid impurities from the air without impeding air flow. The UV System emits ultraviolet light to damage the DNA structure of certain microbes at the cellular level and inactivate various viral, bacterial, and fungal organisms, ‘providing filtration and disinfection in one’. Honeywell EACs with UV Systems can be installed inside a commercial HVAC system, without having to remove old equipment and install a new system entirely. They can also be retrofitted, since only a minimal pressure drop occurs, and – Honeywell claims – can help save energy while providing a better heat exchange, and can pay for themselves with the savings.
The new Honeywell IAQ sensors are designed ‘to help building owners better determine a building’s environmental state and air quality status, and allow them to take corrective actions through the building management system. New sensors can be added to existing temperature, humidity, and CO2 sensors, or users can deploy new All-in-one IAQ sensors to cover multiple sensing requirements in one device.
Using an optical sensor based on laser scattering principles, and featuring ‘innovative contamination resistance technology’ to perform ‘highly accurate and reliable’ PM measurements, the new Honeywell PM2.5 particulate matter sensor detects particles with a diameter of 2.5 micrometres and under.
The Honeywell All-in-One IAQ sensor is a single unit comprising a ‘multi’sensor’ suite including temperature, relative humidity, CO2, PM2.5, and TVOC, focusing on overall thermal comfort and air quality. It can be used to cover multiple air quality factors to communicate healthy building status and enable the appropriate actions with the BMS.
