Refrigeration and Air Conditioning: Core Concepts and Exam Prep

Preparing for competitive engineering exams or entering the HVAC industry requires a rock-solid grasp of thermal dynamics and system cycles. This text-based guide breaks down complex thermodynamic equations and system designs into clear, readable explanations. By studying these structured modules, you will transition from basic thermal definitions to confidently analyzing cooling cycles and solving technical problems. What you'll learn: Understand the fundamental thermodynamic principles of vapour compression and vapour absorption systems; Analyze gas refrigeration cycles and their primary industrial applications; Evaluate different types of refrigerants, focusing on modern eco-friendly, low-GWP alternatives; Identify and explain the functions of core components, including compressors, condensers, and expansion devices; Solve classic engineering problems and exam-style questions using step-by-step written derivations; Apply energy efficiency metrics like COP and modern performance standards to system evaluations. The course begins with foundational definitions of heat transfer before moving systematically through cycle analysis, component mechanics, and environmental standards. You will solidify your knowledge through detailed written walkthroughs of classic exam problems. This course is designed for engineering students, exam candidates, and beginners looking for a structured, text-based introduction to thermal systems with no prior advanced HVAC experience required.
