Troubleshooting and Servicing Modern Air Conditioning & Refrigeration Systems

John Tomczyk

In today's ever changing technical world, service technicians must be highly skilled and have a solid understanding of refrigeration and air conditioning concepts. In addition, technicians must stay abreast of current industry development and improved techniques.

Troubleshooting and Servicing Modern Air Conditioning and Refrigeration Systems gives service technicians all the information needed to accurately diagnose and solve various systems problems.

The book details a variety of topics and troubleshooting procedures, including the following: Refrigerant pressures, states, and conditions, Subcooling and superheat, Compression systems, Metering devices, System charge, Diagnosing air conditioning systems, Systematic troubleshooting, Alternative refrigerants, Refrigerant blends an oils, Leak detection - evacuation and clean up procedures, Ozone depletion and global warming.

Troubleshooting and Servicing Modern Air Conditioning and Refrigeration Systems discusses the changes affecting the refrigeration and air conditioning industries with an emphasis on the phaseout of CFC and HCFC refrigerants.

Detailed sections on the most current leak detection and evacuation methods are included, as well as a section on alternative refrigerants and retrofit guidelines. The book also includes refrigerant changeover guidelines for the following conversions: R-12 to R-134a; R-12 to R-401A; R-12 to R-401B; R-502 to R-402A/R-408A; and R-502 to R-404A/R-507.

It is written in easy to understand language and utilizes a large number of illustrations, tables, and photos. This book will provide service technicians with the practical, hands on information needed to successfully troubleshoot and service today's increasingly complex air conditioning and refrigeration systems.

Troubleshooting and Servicing Modern Air Conditioning and Refrigeration Systems helps students develop an ability to troubleshoot systems and solve problems in an efficient and timely manner. Although some textbooks address the subject, the coverage is more often cursory than detailed. Troubleshooting and Servicing Modern Air Conditioning and Refrigeration Systems is a textbook that thoroughly covers the subject in an easy to understand format and is an excellent addition to any curriculum

John Tomczyk the author of Troubleshooting and Servicing Modern Air Conditioning and Refrigeration Systems is a professor of refrigeration, heating and air conditioning at Ferris State University.

Professor Tomczyk has written many technical articles and is the co-author of Refrigeration & Air Conditioning Technology, now in its' Sixth Edition by, Whitman, Johnson and Tomczyk, a Delmar publication.
