Psychrometric Chart and RAC Fundamentals for Engineering Exams

Understanding the properties of moist air is fundamental to mastering thermal engineering and passing competitive exams. This text-based course breaks down the complexities of the psychrometric chart into clear, digestible written explanations and step-by-step calculations. You will transition from guessing chart values to confidently analyzing air conditioning processes. By studying foundational thermodynamic definitions and practicing with structured written exercises, you will develop the analytical skills required to solve challenging exam problems with precision. What you'll learn: Understand key air properties including dry bulb, wet bulb, and dew point temperatures; Read and interpret psychrometric charts accurately using step-by-step written guides; Calculate specific humidity, relative humidity, and the degree of saturation; Analyze thermal processes using sensible heat factors and bypass factors; Solve practical refrigeration and air conditioning problems step-by-step; Learn how modern digital software tools complement manual chart calculations. The course starts with fundamental definitions of moist air properties before guiding you through chart navigation, process lines, and practical engineering calculations. You will reinforce your learning through written exercises designed to mirror exam-style questions. This course is designed for engineering students, HVAC beginners, and candidates preparing for competitive exams like GATE. No prior experience with psychrometrics is required, though a basic understanding of engineering thermodynamics is helpful.
