In Part 2: Reading a Psychrometric Chart, I demonstrated how to read a psychrometric chart by using any two air conditions to find other parameters. In the third and final part of this Pschryo Series, we will be applying psychrometrics to solve a common problem with cold storage facilities. Humidity and Cold Storage Don’t Mix A …

In Part 1: Demistifying Psychrometrics, I provided the scientific definition and a little explanation for the terms used in psychrometrics. In the second part of this series, we will use these terms and learn how to read a psychrometric chart. Psychrometric Chart A psychrometric chart packs a tremendous amount of information in an odd looking …

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 …
