Fundamentals of Refrigeration and Air Conditioning System Design

Cooling technologies are essential to modern infrastructure, from residential comfort to industrial food preservation. Understanding how these systems operate, cycle, and perform is crucial for any aspiring mechanical or building services engineer. This course guides you through the core scientific principles and practical design equations of refrigeration and air conditioning. You will transition from basic thermodynamic concepts to analyzing complex cooling cycles and performing precise load calculations. What you'll learn: 1. Understand the foundational laws of thermodynamics as they apply to vapor compression and absorption cycles. 2. Analyze the properties of moist air using psychrometric charts and calculations. 3. Calculate cooling and heating loads for residential and commercial spaces using standard design criteria. 4. Evaluate different types of refrigerants, focusing on modern, eco-friendly alternatives and global warming potential standards. 5. Design basic duct systems and select appropriate air distribution components. 6. Solve practical engineering numerical problems related to coefficient of performance and system efficiency. The course starts with essential terminology and thermodynamic definitions before moving into cycle analysis, psychrometrics, and load estimations. You will work through clear, step-by-step written derivations and solved engineering problems to build your practical analytical skills. This text-based guide is designed for engineering students, HVAC technicians, and beginners looking for a structured, formula-focused introduction to cooling systems with no prior advanced thermodynamics required.
