Core Principles of Refrigeration and Air Conditioning (RAC)

Engineers and technicians need a solid grasp of how cooling and heating systems operate to ensure efficiency, reliability, and regulatory compliance. This course provides a rigorous, text-based foundation in RAC principles, enabling you to confidently analyze vapor compression cycles, assess equipment performance, and handle critical calculations used in the industry today. What you'll learn: * Understand the laws of thermodynamics applied to cooling systems and the concept of the ton of refrigeration. * Analyze the Vapor Compression Refrigeration (VCR) cycle using P-H and T-S diagrams and calculate the Coefficient of Performance (COP). * Master the function and selection criteria for key components like compressors, condensers, evaporators, and expansion devices. * Examine psychrometric processes and apply psychrometric charts for air conditioning load calculation and system design. * Evaluate modern performance metrics (EER, SEER) and the environmental impact of current refrigerant types and regulatory trends. The course begins with foundational concepts and definitions, progresses through detailed analysis of major refrigeration cycles, and concludes with practical applications in air conditioning and modern efficiency standards. This course is designed for absolute beginners, including students and aspiring mechanical engineers, with no prior knowledge of refrigeration or thermodynamics required.
