Psychrometric Analysis Course
Learn practical psychrometric analysis for AHU cooling coil sizing, air conditioning process analysis, AHU selection review, and troubleshooting.
Also included in Basic Membership from $20/month or $220/year.
Psychrometrics Is Difficult When You Only Learn the Chart
You know how a psychrometric chart looks, but still struggle to connect the chart with cooling coil sizing, mixed air, fan heat gain, duct heat gain, AHU selection, and real air conditioning problems.
You Can Read Points, But Not the Full Process
You know dry bulb, wet bulb, humidity ratio, and enthalpy, but still feel unsure how to connect them into a complete air conditioning process.
Cooling Coil Sizing Feels Unclear
You know the cooling load, but still struggle to determine off-coil temperature, on-coil temperature, coil capacity, sensible heat ratio, and mixed air condition.
AHU Selection Reports Are Hard to Interpret
You receive an AHU selection report, but still feel unsure how to compare the selected coil, fan, airflow, static pressure, and actual performance against your design.
Troubleshooting Without Psychrometrics Becomes Guesswork
When a system has cooling, humidity, or airflow issues, you know something is wrong but not know how to use air properties to identify the likely cause.

How Psychrometric Analysis Fits Into HVAC Design
Psychrometrics connects air temperature, humidity, cooling load, coil capacity, outdoor air, fan heat, duct heat gain, and AHU selection.
Without psychrometric analysis, it is difficult to properly understand:
- Why a cooling coil is sized a certain way?
- How supply air condition is determined?
- How outdoor air affects coil load?
- How fan heat affects supply air?
- Why AHU selection differs from design calculation?
- Why some rooms feel cold but humid?
- Why an air conditioning system may struggle under certain conditions?
This course helps you understand the air-side behavior behind HVAC design and troubleshooting.
