Automotive Air Conditioning Training Manual
Comprehensive automotive air conditioning training manual covering refrigeration theory, system architecture, and hands-on service procedures. Explores heat transfer principles, pressure-temperature relationships, and R134a refrigerant properties essential to understanding modern climate control systems. Details all major components—compressors, condensers, evaporators, expansion valves, and orifice tubes—along with electrical control circuits and their operation. Includes practical guidance on retrofit procedures, use of recovery and recycling equipment, and systematic troubleshooting of common A/C faults. Equips technicians with the knowledge needed to diagnose electrical and refrigerant-side problems, evaluate system performance, and execute proper service workflows.
