Refrigeration & AC

This course provides a comprehensive understanding of refrigeration and air-conditioning systems, covering fundamental principles, components, design concepts, and practical applications. Participants learn the basics of thermodynamics, heat transfer, refrigeration cycles, and psychrometrics relevant to HVAC&R systems. The course explains the working principles of vapor-compression and other commonly used refrigeration systems. It covers major components such as compressors, condensers, evaporators, expansion devices, and refrigerant circuits. Participants gain knowledge of different types of air-conditioning systems and their applications in residential, commercial, and industrial environments. The course introduces refrigerants, their properties, selection criteria, environmental considerations, and safe handling practices. It also covers cooling load estimation, system sizing, and basic equipment selection. Participants learn about ventilation, humidity control, air distribution, and indoor environmental conditions. Practical aspects of system operation, maintenance, troubleshooting, and energy efficiency are also addressed. The course helps participants develop the technical knowledge required to understand, operate, maintain, and improve modern refrigeration and air-conditioning systems.
