Basic Refrigeration & Air Conditioning

Basic Refrigeration & Air Conditioning provides a strong foundation in the principles, components, operation, and maintenance of refrigeration and air-conditioning systems. The course introduces participants to refrigeration cycles, heat transfer, pressure-temperature relationships, and basic thermodynamic concepts. It covers the working principles and functions of compressors, condensers, expansion devices, evaporators, and refrigerants. Participants learn about different types of refrigeration and air-conditioning systems used in residential, commercial, and industrial applications. The course explains refrigerant charging, recovery, evacuation, and basic system servicing practices. It also introduces electrical and control components commonly used in RAC systems. Practical approaches to system inspection, performance monitoring, and basic troubleshooting are emphasized. Safety practices, refrigerant handling, and environmental considerations are also covered. By the end of the course, participants will have the knowledge required to understand, operate, maintain, and troubleshoot basic refrigeration and air-conditioning systems.
