Ultraviolet C (UV-C) technology has been used since the 1990s to eliminate microbial buildup on cooling coils, air filters, duct surfaces, and drain pans. But despite the technology’s history and track record, some facility engineers remain uncertain. On the other hand, some come around quickly.
Good IAQ management has become paramount in the construction industry, as study after study shows that employee productivity and health are directly related to the quality of air being delivered inside the workplace environment.
Budgets, codes, and technologies are constantly shifting and evolving. These days, even the classrooms are often portable. Staying one step ahead will depend on your knowledge of current design options and how to integrate them into the space.
Whether kids like school or not, attendance is mandatory for many years. Academic performance during this time often influences eventual jobs, income, and life satisfaction. During the formative years, parents mandate adequate sleep and good eating habits to improve their children’s concentration.
When I got started in the HVAC business half a century ago, I was very fortunate to work for a small firm where I learned a lot about design engineering from some really knowledgeable and practical HVAC engineers. The business we were in was designing HVAC for hospitals, colleges, universities, research facilities, and museums. All of these facilities required very sophisticated central air systems, heating systems, and chilled water systems.
These sensitive applications call for looking at several established humidification techniques through a particular lens. The authors not only review the processes involved in various technologies but also some relevant secondary effects, such as a change (or no change) in the air temperature, that could be especially meaningful in a data center.
