Principles of Refrigeration and Air Conditioning Systems

Cooling systems are essential to modern life, from preserving food to maintaining comfortable indoor environments. Understanding how these systems operate is the key to designing energy-efficient and sustainable thermal solutions. In this text-based course, you will build a solid foundation in the thermodynamic cycles, components, and load calculations that power refrigeration and air conditioning systems. What you will learn: Understand the fundamental principles of thermodynamics, heat transfer, and psychrometrics; Analyze vapor compression and vapor absorption refrigeration cycles; Identify key components including compressors, condensers, evaporators, and expansion devices; Calculate heating and cooling loads for residential and commercial spaces; Explore eco-friendly refrigerants and modern energy-efficiency standards. You will begin with foundational terminology and thermodynamic laws before moving step-by-step through cycle analysis, system components, and real-world psychrometric applications. This course is designed for engineering students, technicians, and beginners with no prior HVAC experience who want to understand thermal systems.
