In Part 1: Why, How and What, of this series, I discussed why more ventilation is needed, how much is required and what type of filtration should be used. In Part 2, I’ll discuss what needs to be considered to redesign an existing ventilation system to add more air flow and HEPA filtration. Adding HEPA Filtration …

As the United States begins to open up, one of the biggest concerns is how do we keep people safe in places like schools and offices. Social distancing and wearing protective gear is obviously part of the solution to minimize the potential for transmission. But preliminary studies out of Asia found that the COVID-19 …

The COVID-19 pandemic will have a long-term impact on how we interact with people in many ways. One of those impacts will be on how we circulate and filter the air in common spaces such as offices and retail outlets. Until now, indoor air standards have been based primarily on thermal comfort with some attention …

The COVID‐19 pandemic has been exceptionally hard on the world‐wide cruise line industry. This highly contagious air borne pathogen has pointed out the design weaknesses of recirculating ventilation systems on ships. To better protect the safety and health of their crew and guests in the future, cruise lines will need to convert their ships with …

In terms of general ventilation for a manufacturing facility, successful work environments are ones one where employees are not feeling thermal discomfort and can be 100% productive throughout their shift. This type of environment is sometimes difficult to imagine in the summertime when the outside temperature is in the 90’s. However, a well designed ventilation …

In Part 2: How It Works of this series, we learned that the silica gel rotor was the key development which allowed for one continuous process with two separate air flows for moisture adsorption and silica gel regeneration. In Part 3, I’ll explain how we customize a desiccant dehumidifier for some common applications. Cold Storage/Freezer …
