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.
