Psychometrics and the Properties
of Air

What You Will Learn

Understanding psychrometrics and air properties is crucial for managing and maintaining space conditions. While designers often rely on software to calculate important values for cooling, heating, humidifying, and dehumidifying, it's essential to comprehend how these measurements are determined. Psychrometric charts may seem complex, but our webinar will simplify the information they provide. By the end of the session, you'll gain a clear understanding of psychrometric charts, air properties, and the essential processes involved in regulating climate control in modern buildings.

Key topics include:

Properties Of Air
Building The Psychometric Chart
Moving Around The Chart
Determine Air Properties
RH Vs Dew Point

Key questions answered during the webinar:

What does the dot represent at 75 degrees Fahrenheit & relative humidity is 50%?
Are there psychrometric charts that are extended to very warm temperatures? How do we find the air properties?
Can you provide the Psychometric Chart in SI units?
Explain why relative humidity can never reach 100% when conducting sensible cooling?
At what elevation do we need to consider using a high-altitude psychrometric chart?
Is there a calculation to size a dehumidifier (pints/day) to maintain a relative humidity of 60% based on design day information?
Why are all psychrometric charts not the same? What chart is considered the most accurate in the industry?
Why is the line for dry bulb not perfectly straight up?
Where does the vapor barrier need to be: Warm side or cold side?
Is Wet Bulb a useful property in itself or is it just a means to find the other properties?
Does humidity equalize based on relative humidity (RH), humidity ratio (W), or something else?
Which is higher: dew point or wet bulb, and why is there a difference?
