Overview

About the Product

Technicians trained on air conditioning systems are often required to apply their skills to the servicing of commercial refrigeration equipment. This book provides a solid foundation in comfort cooling that can be readily transferred to a broad understanding of medium and low temperature refrigeration equipment such as walk-ins, reach-ins, refrigerated cases, and ice machines. Coverage specific to refrigeration in the food service industry is emphasized, with scores of practical tips that technicians can use right away in the installation and service of commercial equipment. Helpful tips and sound advice from the experienced author and his employees add a personal touch to the comprehensive coverage, increasing interest in, and retention of, key concepts. This book will improve technicians' knowledge, efficiency, and effectiveness in commercial refrigeration and can serve as a permanent addition to the reference library in any truck or shop.

Features

  • Coverage is delivered in a fun, conversational, and easy-to-understand tone, with immediate and practical application to situations likely to be encountered on the job.

  • "Rules of Thumb" for diagnosing service problems help prepare technicians for troubleshooting in those situations where factory recommendations and specifications are not readily available.

  • Abundant diagrams and pictures illustrate key concepts, aiding visual learners in grasping the information presented.

  • The back-of-book CD features animated versions of important concepts.

Instructor Resources  (ISBN-10: 1428335277 | ISBN-13: 9781428335271)
Electricity for Refrigeration, Heating, and Air Conditioning  (ISBN-10: 1418042870 | ISBN-13: 9781418042875)

Ideal for students and beginning technicians, Electricity for Refrigeration, Heating and Air Conditioning, 7E zeroes in on the basic electrical principles necessary to understand today's modern control systems. This extraordinarily practical approach allows readers to focus exclusively on the electronics information they will use in the field, without bogging them down in unnecessary theory. Chapter 9 includes new information on motor frames and electronically commutated motors, ECM. Such as the circuits being discussed in schematic diagrams, as well as the direction of the current flow within circuits. As in past editions, emphasis is on developing systematic diagnosis and troubleshooting methods and procedures in order to enable readers to become highly-skilled, professional HVAC-R service technicians. A comprehensive glossary is also included to assist those who are new to the field in understanding and using industry terms.

Practical Problems in Mathematics for Heating and Cooling Technicians  (ISBN-10: 1428324283 | ISBN-13: 9781428324282)

Develop solid practical math skills needed to succeed in the heating and cooling technology field with this updated resource that presents critical information in a way that is straightforward, easy-to-understand, and most importantly, meaningful to the reader. From basic arithmetic to using formulas, Practical Problems in Mathematics for Heating and Cooling Technicians, 5th Edition covers all of the mathematical concepts that technicians are likely to encounter in their everyday, on-the-job tasks. Packed with hands-on exercises and the HVAC-R-specific terminology that previous editions are known for, this updated edition includes references to the latest technology, geothermal systems, as well as zone heating and cooling. Readers will walk away with a thorough understanding of need-to-know math concepts, as well as confidence that they can apply what they have learned immediately and effectively.

Refrigeration and Air Conditioning Technology  (ISBN-10: 1428319360 | ISBN-13: 9781428319363)

Refrigeration and Air Conditioning Technology, 6th Edition, a time-honored best seller, has been updated and revised to provide superior hands-on information needed to successfully maintain and troubleshoot today's complex heating, air conditioning, and refrigeration systems. The new sixth edition contains units updated to include advances or changes in technology, procedures, and or equipment. Over 250 new images have been added to emphasize the practical application approach to the book. It fosters a solid foundation and understanding of environmental problems and their solutions, and displays a depth and detail of theory, diagnostics, and repair procedures that make this a fitting book for basic HVAC-R education as well as upgrading and certification training for technicians in the field.

Refrigeration: A Residential and Light Commercial Text & Lab Book  (ISBN-10: 1418005606 | ISBN-13: 9781418005603)

This "how-to" lab book creatively combines both theory and practical application into an organized system for learning about domestic and commercial refrigeration equipment. Ideal for use as a stand-alone manual or alongside any HVAC publication, this versatile guide offers brief theory lessons of what is to be learned followed by practical competencies that take readers step-by-step through specific procedures. These opportunities for "hands-on" application of key concepts help readers better understand common service, repair, and maintenance procedures. The flexible format affords users the unique opportunity to learn domestic and commercial refrigeration fundamentals and applications either on an individual basis or in an instructional setting.
