Enthalpy? A Fancy Word for Heat!
This program presents the important concepts of pressure enthalpy in a manner that will appeal to students, service technicians, and educators. Each refrigerant has its own set of unique properties, and these properties are compiled on the pressure- enthalpy chart for that particular refrigerant. The pressure- enthalpy chart facilitates the creation of a picture, or "snapshot" of the entire system's operation. Once the concepts of pressure enthalpy have been mastered, a field service technician should be able to effectively and accurately start up, troubleshoot and evaluate air conditioning and refrigeration systems using a properly completed pressure-enthalpy chart.
Training Manual © 2027 ESCO - 225 Pages
The book starts by reviewing the basic vapor-compression refrigeration cycle, as well as the concepts of superheat, subcooling and temperature/pressure relationships. The book then turns to the pressure-enthalpy chart, where simplified diagrams are used to provide a comprehensive overview of the meaning and purpose for every line on the chart. After combining the basic refrigeration cycle's concepts and the pressure-enthalpy chart to create an in-depth system illustration, the plotting of actual systems follows next. The completed plots allow for the evaluation of various system parameters and the calculation of many system characteristics, including system capacity and efficiency. It is during this evaluation process that system problems can be easily identified.
The book has a section that is devoted to system troubleshooting, identifying visual clues on the completed chart to lead service personnel to the underlying cause for system failure. To aid the reader in fully understanding the true power of pressure-enthalpy, detailed system comparisons are provided to highlight the differences between properly operating systems and those that are malfunctioning. Once the concepts of pressure enthalpy have been mastered, the reader can truly appreciate this tool and its usefulness to effectively and accurately start up, troubleshoot and evaluate air conditioning and refrigeration systems.

About the Author
Over the past forty-five years, Eugene has been involved in all aspects of the HVACR industry from field technician and system designer to company owner, teacher, administrator, consultant, college professor, and author. Eugene is presently serving as the National Programs Director at HVAC Excellence, a division of the ESCO Group, based in Mount Prospect, IL. Eugene has over thirty years of teaching experience and has taught at several private, secondary and postsecondary institutions. He can be seen at many national HVACR events, where he, as a popular guest presenter, speaks on many different topics important to our industry.
Eugene earned his dual bachelor's degree from The City College of New York, where he studied electrical engineering, economics, operations management, marketing, and finance. He earned his Master of Science degree from Stony Brook University, where he specialized in Energy and Environmental Systems, studying renewable and sustainable energy sources including wind, solar, geothermal, biomass and hydropower. He earned his Certified Master HVACR Educator (CMHE) credential in 2010 from HVAC Excellence. Eugene also carries the BEAP credential issued by ASHRAE, which classifies him as a Building Energy Assessment Professional.
As an active member of various industry organizations, including ASHRAE and IEEE, Eugene served as the subject matter expert and wrote the production scripts for dozens of educational videos directly relating to our industry in addition to co-authoring the number one HVACR textbook in the industry, "Refrigeration and Air Conditioning Technology", presently in its 10th Edition, published by Cengage Learning. This book is used in over 1,200 schools both in this country and abroad to help individuals learn, and master, the skills required to service, install, design, service and troubleshoot HVACR equipment.
Other book credits include Refrigeration and Air Conditioning Technology, 6th, 7th, 8th, and 9th Edition, Residential Construction Academy: HVAC, 1st and 2nd Edition, (Cengage, 2005, 2012), The Complete HVACR Lab Manual, 1st and 2nd Editions (Cengage, 2019, 2023), Heat Pumps, 1st and 2nd Editions (Cengage, 203,2016), Print Reading for HVAC 1st and 2nd Editions, (Goodheart-Willcox, 2021, 2026), Psychrometrics Without Tears (2014), and the newly released Electricity Theory and Applications (Goodheart-Willcox, 2027). Eugene has also written numerous articles for industry newspapers and magazines.
Eugene was selected as one of the top three HVACR instructors in the country for the 2005/2006, 2006/2007 and 2007/2008 academic school years by the Air Conditioning and Refrigeration Institute (ARI), now AHRI, and the Air Conditioning, Heating and Refrigeration (ACHR) News. In January 2024, Eugene received HVAC Tactical's lifetime achievement award, which was presented at their 2024 awards ceremony in Chicago, IL.
