Pressure Enthalpy Without Tears Manual
Enthalpy? A Fancy Word for Heat!
Training Manual © 2014 ESCO -150 Pages
The book starts by reviewing the basic vapor-compression refrigeration cycle, as well as the concepts of superheat, sub-cooling and the pressure/ temperature relationship. The book then turns to the pressure enthalpy chart, giving an overview of the meaning and purpose for every line on the chart. Simplified charts are used to clarify the explanations. The plotting of actual systems follows next. The completed plot allows for the evaluation of various system parameters and the calculation of many system characteristics, including system capacity and system efficiency. It is during this evaluation process that system problems can be easily identified.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.

Eugene has twenty years of teaching experience and has taught at Apex Technical School and Nassau BOCES. Eugene is particularly excited about his present position as an Assistant Professor at Suffolk County Community College, as this is the only institution on Long Island to offer, not only a one-year certificate in HVAC/R, but also a two-year Associates of Applied Science degree, A.A.S., in HVAC/R.Eugene earned his dual Bachelors Degree from The City College of New York and his Masters of Science degree from Stony Brook University, where he specialized in Energy and Environmental Systems, studying renewable and sustainable energy sources such as wind, solar, geothermal, biomass and hydropower. He earned his Certified Master HVAC/R Educator credential from HVAC Excellence and the ESCO Group after completing a battery of 7 educator-level examinations in a variety of content areas including Air Conditioning, Refrigeration, Heating, Heat Pumps and Electricity. Eugene also carries the BEAP credential issued by ASHRAE. This credential classifies Eugene as a Building Energy Assessment Professional.As an active member of both ASHRAE and RSES, Eugene served as the subject matter expert and wrote the production scripts for over thirty education videos directly relating to our industry in addition to authoring the number one HVAC/R textbook in the industry, "Refrigeration and Air Conditioning Technology, 7th Edition" published by Cengage Learning. This book is used in over 1,000 schools both in this country and abroad to help individuals learn, and master, the skills required to service, install, design, service and troubleshoot HVAC/R equipment.Other book credits include Refrigeration and Air Conditioning Technology, 6th Edition, Residential Construction Academy: HVAC, 1st and 2nd Edition, Pressure Enthalpy Without Tears (2006), Heat Pumps (2002) and, of course, Psychrometrics Without Tears (2013). Eugene has also written a number of articles for industry newspapers and magazines.Eugene was selected as one of the top three HVAC/R 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.
