Overview

Now in its Fourth Edition, the ever-popular COMMERCIAL REFRIGERATION FOR AIR CONDITIONING TECHNICIANS helps readers apply existing HVACR skills to new concepts in order to service medium- and low-temperature refrigeration equipment such as walk-ins, reach-ins, refrigerated cases and ice machines. Chapters emphasize refrigeration in the food service industry, offering practical tips from the author and other experienced professionals on installing, servicing and troubleshooting commercial equipment. Extensively updated throughout the text, the Fourth Edition includes a simplified, step-by-step flowchart for quickly diagnosing and addressing the nine most common refrigeration problems on the job--as well as new information on the latest advances in commercial refrigeration. Ideal for advanced refrigeration courses, the text features new key terms and updated review questions to conclude each chapter, and online instructor resources include quiz and exam test banks and animated PowerPoint® slides for classroom presentations. Equally valuable as a real-world resource to keep on hand in the truck or shop, COMMERCIAL REFRIGERATION FOR AIR CONDITIONING TECHNICIANS, Fourth Edition, is an indispensable tool for any technician working with commercial refrigeration today.

What's New

{{collapseContainerClosed['whats-new'] ? 'Show More' : 'Show Less'}}
  • A list of Key Terms has been added to the end of each chapter to help with student review and assessment, and most essay-style review questions have been changed to multiple-choice for easier integration into the MindTap testing database.
  • Chapter 7 (Refrigeration System Troubleshooting) has been completely revised and simplified to better facilitate teaching and learning, making it easier for readers to master a comprehensive, step-by-step approach to identifying common refrigeration issues. In addition, the diagnostic flowchart now combines similar problems to allow for three new additions among the nine problems areas covered.
  • Chapter 9 (Retrofitting, Recovery, Evacuation, and Charging) includes numerous updates and additions to keep pace with evolving industry standards. For example, retrofitting of R12 and R502 is no longer covered, and R22 examples of commercial refrigeration have been replaced with R404A where possible. The chapter also covers high-glide refrigerants such as R448A extensively, especially as they relate to determining superheat, sub-cooling, evaporator and condensing temperature and control set points. An overview of highly flammable refrigerants such as propane (R290) is also included.
  • The author has updated chapter material throughout the Fourth Edition to reflect current industry trends, technology and best practices, bringing information up to date and making the new edition especially useful for today's technicians.
