About this course

Temperature control is essential for modern comfort, food preservation, and industrial processes. This text-based course introduces you to the core science and practical engineering behind refrigeration and air conditioning systems. You will transition from understanding basic thermodynamic cycles to analyzing real-world cooling systems, preparing you to evaluate performance and understand modern, eco-friendly HVAC technologies. What you'll learn: - Understand the fundamental thermodynamic cycles, including vapor compression and vapor absorption. - Analyze the properties of modern, eco-friendly refrigerants and their environmental impacts. - Calculate system efficiency using Coefficient of Performance (COP) and energy-efficiency ratios. - Identify the key components of cooling systems, such as compressors, condensers, evaporators, and expansion devices. - Evaluate psychrometric charts to solve air conditioning and thermal comfort problems. - Explore modern heat pump applications and energy-saving climate control systems. The course begins with foundational definitions of heat transfer and thermodynamics before guiding you through system components, psychrometrics, and sustainable cooling practices. You will work through written explanations, practical formulas, and self-assessment exercises to solidify your knowledge. This course is designed for engineering students, aspiring HVAC technicians, and curious beginners. No prior background in thermodynamics is required.
