Synopsis

Extensively illustrated, clearly written, and state-of-the-art in focus, this comprehensive MHVAC manual is ideal for both novice and advanced technicians. ASE-based in coverage, it focuses on the generic theory that underlies the operation, diagnosis, and repair of the MHVAC units and subassemblies found in the many makes and types of vehicles students will likely encounter on the job. Features 52 Real-World Fixes (case studies) showing how technicians have solved and repaired difficult problems, and 85 Service Tips (procedures that can bring a job to completion faster or ensure a more thorough repair). The volume has the support of much of the RVAC and Santech Industries cooling system repair industry. Basics of Heating and Air Conditioning. Heat Movement Theory. Refrigerants and the Environment. Moving Heat: Heating and Air Conditioning Principles. Air Conditioning Systems. Air Conditioning System Components. Heating Systems. Air Management Systems. HVAC System Inspection and Trouble Diagnosis Procedures. A/C System Inspection and Diagnosis. Heating and Air Management Systems Inspection and Diagnosis. HVAC System Electrical or Electronic Controls, Theory, Inspection, and Diagnosis. Refrigerant Service Operations. A/C System Repair. Cooling System Theory. Cooling System Inspection, Trouble Diagnosis, and Service. A reference for working automotive MVAC technicians.

About this title

From the Publisher

This text helps students learn the basics of automotive heating and air conditioning systems. The book covers both Theory and Service and Repair. The Theory chapters provide the student with an understanding of how these systems work, terminology, and the variety of systems that can be found. The Service and Repair chapters complete the coverage of each area by describing how to maintain , diagnose, repair, and adjust the unit. These service procedures follow guidelines recommended by SAE, MACS, IMACA and most vehicle manufacturers.

The automobile has undergone a continuous evolution since its introduction in the late 1800s. Today's vehicles still incorporate most of the major features of the very early vehicles, yet are vastly different in many aspects. Numerous comfort features, such as heating, air conditioning, and ventilation (HVAC) systems, have- been added to make driving safer and more enjoyable. Durability and longevity have increased continuously, although vehicles still break and wear out. Drivability and fuel mileage are slowly but steadily improving, while exhaust emissions are steadily decreasing.

The HVAC system is becoming one of the more durable areas of a vehicle while also becoming very complex with electronic controls, such as dual- and three-zone temperature controls. Also, the lingering effects of environmental regulations for chlorofluorocaxbon (CFC) and in the near future hydrochlorofluorocarbon (HCFC) reduction are causing refinements in HVAC system service procedures. These changes are affecting millions of older vehicles that are still on the road. As the automobile becomes more sophisticated and complex, more sophisticated technicians with better training are required to keep up with the changes in regulations, to determine the causes of any malfunction, and to repair problems.

Automotive Heating and Air Conditioning, Third Edition, was written to help the student understand the HVAC system used in cars, sport utility vehicles, pickups, light trucks, and vans. It describes the theory of operation for the major power transfer and control systems, as well as the methods to diagnose and repair common problems. The text covers traditional and modern HVAC systems and engine cooling systems. This edition has been expanded to include new regulations and service methods. It is arranged so that the major components of these systems are described completely with regard to theory of basic operation and methods used to diagnose, adjust, and repair problems.

The theory chapters (1 through 8 and 15) provide the student technician with an understanding of how the various systems work, the terminology used, and the variety of systems that can be encountered. For example, there are three major ways of transmitting motion and force from the HVAC control head to the airflow control doors. Modern HVAC systems use electronics for the same purpose that earlier systems used mechanical cables. Even though these newer systems are based on principles of the past, the modern technician needs to keep abreast of the technical advancements as vehicles evolve. If he or she understands how the systems operate, successful problem diagnosis and repair become much easier.

The service and repair chapters (Chapters 9 through 14 and 16) complete the coverage of each system by describing the procedure used to maintain a system for proper operation; diagnosing the cause of a problem if it does occur; and then repairing or adjusting the unit to correct the root cause of the problem. These topics are covered in a very generic fashion, to apply to as many makes and types of vehicles as possible. Service information in a printed or electronic form is commonly used in automotive repair industry. It takes more than just the ability to read for the student-technician to understand and use this information effectively. This author intends not to replace these manuals, but rather to supplement them so the student-technician can gain full benefit from these valuable sources of information. This book describes how to perform service operations, and the service information tells what operations are necessary for a particular service operation.

The service chapters have been made more realistic by the addition of Service Tips, which describe procedures that can bring a job to completion faster or ensure a more thorough repair. Real World Fixes have also been added; these are case studies of how technicians have solved and repaired problems.

This book covers all the areas contained in the Automotive Service Excellence (ASE) test for Automotive Heating and Air Conditioning, and the ASE Task List for this area is included as Appendix A. With class instruction and shop experience, the student-technician should have no trouble passing this test.
