UNDERSTANDING PSYCHROMETRICS HANDBOOK
Understanding moist air is essential for anyone involved in HVAC design, ventilation, thermal comfort, humidity control, air-conditioning, and building performance. Yet psychrometrics can become difficult when equations, charts, properties, and processes are presented without a clear connection to real engineering decisions.

UNDERSTANDING PSYCHROMETRICS HANDBOOK provides a practical way to understand how temperature, moisture, pressure, enthalpy, humidity ratio, dew point, wet-bulb temperature, and airflow work together inside HVAC systems. The book explains not only how to calculate psychrometric properties, but also how to interpret what those values mean when designing, operating, or troubleshooting real systems.

The book begins with the properties of dry air, water vapour, and moist air before moving into saturation, relative humidity, dew point, wet-bulb temperature, and the psychrometric chart. Readers then learn how to analyse sensible heating and cooling, humidification, dehumidification, evaporative cooling, air-stream mixing, cooling coils, reheat, desiccants, ventilation, heat recovery, thermal comfort, condensation, climate effects, altitude, measurements, and complete HVAC processes.

What makes this handbook different is its strong connection between theory and application. Equations are developed carefully, variables and units are explained, and calculations are shown step by step. Psychrometric charts are treated as engineering tools rather than confusing diagrams. Complex processes are broken into understandable state points, balances, and system components so readers can see how each decision affects temperature, moisture, energy, and indoor conditions.

The handbook includes:

• Clear explanations of moist-air properties and psychrometric relationships
• Step-by-step worked calculations using SI units
• Practical psychrometric chart interpretation
• Sensible and latent load calculations
• Heating, cooling, humidification, and dehumidification processes
• Cooling-coil, bypass-factor, and apparatus-dew-point analysis
• Outdoor-air, ventilation, HRV, and ERV calculations
• Thermal comfort and condensation-control principles
• Canadian climate and altitude considerations
• Measurement, sensors, uncertainty, and calculation methods
• Integrated summer and winter HVAC design applications
• Practice problems for strengthening calculation and design skills

This book is written for engineering students, HVAC technicians, designers, mechanical engineers, commissioning professionals, facility personnel, and building professionals who need to turn psychrometric information into practical decisions.
Whether you are learning psychrometrics for the first time, improving your HVAC calculation skills, checking system performance, or strengthening your understanding of moisture and air-conditioning processes, this handbook provides a structured reference you can return to whenever a psychrometric problem arises.

Build a stronger understanding of moist air, improve your HVAC calculations, and make better-informed design decisions. Get your copy of UNDERSTANDING PSYCHROMETRICS HANDBOOK and put psychrometric principles into practical use.
