Over the years, much has been written on the subject of psychrometrics, or the study of air. Although much of this material has been geared toward engineering and system design, this book presents the important concepts of air in a manner that will appeal to the service technician. Knowing all there is to know about an air sample is pretty empowering, so this book starts by discussing the basic properties of air and how these properties relate to each other. The psychrometric chart is introduced to provide a visual representation of how air behaves when exposed to different conditions. Once the basics of the chart are covered, we then move into some more interesting topics such as sensible heat ratio, bypass factor and apparatus dew point temperatures. These properties help determine system performance and are very important concepts to learn in order to fully understand air. The plotting of actual systems follows next. This involves plotting out air distribution systems that are operating correctly so that we can see what properly operating systems look like on the chart. This book covers a wide range of systems that includes residential heating and cooling systems, as well as commercial systems that provide ventilation air to the occupied space to meet building code requirements. We will discuss mixed air systems and learn to calculate the mixed air conditions provided we know what the outside air and return air conditions are. In addition to everything mentioned already, we will discuss the concepts of ventilation, economizing and air balancing.

'Psychrometrics Without Tears' was a great find for me. The language is straightforward, and it really helps with understanding how to use psychrometric charts. Perfect for my job in climate control applications.

Packaging Issues but Good Content
The book arrived with a bit of damage to the cover, which was disappointing. However, the content is solid and informative. I’ve found it useful, but I wish the shipping had been better.

A Great Introduction to Psychrometrics
I really enjoyed 'Psychrometrics Without Tears'. It's well-written and breaks down complex concepts into digestible parts. The examples are practical and really helped me understand how to apply psychrometric principles in my work.

Helpful, but a Bit Basic
This book is a decent starting point for psychrometrics. It covers the main topics, but I was hoping for a deeper dive into some advanced applications. Still, it’s a solid read if you're new to the field.

Not What I Expected
I had high hopes for 'Psychrometrics Without Tears', but it didn’t really meet my expectations. Some parts felt too simplified, and I was looking for more technical depth. It might be good for beginners, though.
