Basic Refrigeration & Charging Procedures [Paperback]

John Tomczyk (Author)

Book Description

Publication Date: January 6, 2003

Refrigerant pressures, states and conditions are covered, as well as how they apply to the refrigeration system. Vapor pressures, subcooling, superheat, saturation, latent heat, and sensible heat are explained and applied to the refrigeration cycle. Basic system components, their functions and applications are included. Detailed explanations of each point in the refrigeration cycle will clarify questions the reader may have.

Definitions and system applications of subcooling and superheat are also included in this module. Condenser subcooling, total subcooling, evaporator superheat and total superheat are explained with examples as they apply to the basic refrigeration cycle. Friction and static pressure losses, with examples and applications, gives the reader a thorough understanding of how much subcooling is needed in any system.

Advanced topics such as; liquid pressure amplification, superheat suppression, floating head pressure, and refrigerant control systems are included.

This module includes a detailed explanation of refrigerant metering devices which include; thermostatic expansion valves, automatic expansion valves, and capillary tubes. Application, sizing, and troubleshooting under varying system operating conditions are explained.

System charging procedures as they apply to these various types of air conditioning and/or refrigeration systems are included. Charging charts and charging curves with examples of system applications give the reader a thorough understanding of system charging when reading this module.

If you want to read this book or any other from this author just buy Troubleshooting and Servicing Modern AC and Refrigeration systems all ESCO press did was reprint the same info word for word from the above mentioned book and put into three other books by the same author. I bought three other books by this suthor and its the same book.

This review is from: Basic Refrigeration & Charging Procedures (Paperback)

the worst thing about this book is it went into detail on the wrong things.. i.e. liquid amplification, etc.

for 20 bucks it's okay.. but the author is supposed to be well known in the refrigeration field and the title of the book was on refrigeration and charging and should have stuck to a solid foundation on how refrigeration works and how to charge.. in depth that would have given valuable information.. subjects that should have been covered in depth are airflow, humidity, heat load, etc.. how pressures and temperatures move heat and how to accurately measure when a unit is properly charged and what affects making that determination, i.e. heat load etc.. all in all like i said 20 bucks is not much to spend and it mostly gives you that in value.. so it wasn't money wasted.. it just could have been a better book..

If you know basic's but don't know how to charge a walk-in freezer, then this is the book to have. Also, refrigerators, small residential, etc. Althought the superheat and subcool chapter is superb, I already knew most, (not all) of that. But now I know how to charge a walk-in freezer by the sightglass, etc. That is exactly why I bought this book. It also includes the hard to find generic superheat charts.
