About this episode
In this episode, Tony Mormino discusses the history and science behind the psychrometric chart, beginning with its invention by Willis Carrier in 1911. Joined by Kevin Quillinan, the two explore how the chart helps HVAC professionals understand critical air properties, such as heating, cooling, dehumidification, and humidification. Kevin shares how psychrometrics extends beyond HVAC, with applications in agriculture, food processing, and even meteorology. This clip was taken from the main live event on Demystifying Psychrometrics: Understanding the Psychrometric Chart, and the full episode can be seen on our YouTube Channel HVAC TV.
