This book is meant for students as well as young engineers and serviceman in the field of Refrigeration and Air Conditioning. The text is presented in a simple language with the basic principles of Refrigeration and Air Condition and also how these principles can be intelligently applied in the working field.
It's a very readable book and very clear for someone who has some interest in the subject. Would have been perfect if there was some more focus on ammonia system (excusable since that's mostly for industrial), and also details on PLC based system, specifically the control systems.
