Course Description

Welcome to "Refrigeration and Air Conditioning," a comprehensive professional course designed to equip you with essential knowledge and practical skills in the field of refrigeration and air conditioning. Spanning 9 hours and 11 minutes, this course delves into fundamental and advanced concepts that are pivotal for professionals and enthusiasts alike.

Begin your journey with the "Basic Concepts of Refrigeration," where you'll receive an introduction to the principles underlying refrigeration and air conditioning. You'll explore the key components, including the refrigerator and heat pump, along with understanding the significance and calculation of the Coefficient of Performance (COP).

The course further elaborates on the concept of "Tonne of Refrigeration (TR)," refrigeration capacity, and power input. You'll gain insights into the energy efficiency ratio (EER) and the BEE star rating, crucial elements in evaluating the efficiency of refrigeration systems.

Dive deeper into theoretical frameworks with the "Concept of Reversed Carnot Cycle," a foundational model in refrigeration studies. This is followed by an introduction to air refrigeration systems, including a detailed analysis of the Reversed Brayton or Bell Coleman Cycle.

Moving forward, the course examines the "Isentropic Efficiency of Turbine and Compressor" and introduces you to aircraft air refrigeration systems. Here, you'll study the "Simple Aircraft Refrigeration System" and its related processes, including the ramming process and the DART and rating comparison.

The module on vapor compression refrigeration systems offers an in-depth look at the analysis of simple and actual VCR cycles, complete with TS and p-h diagrams. Practical numericals will solidify your understanding of these complex systems.

The segment on "Refrigerants" covers the designation of refrigerants, desirable properties, and their environmental impact, including ODP and GWP. The concept of simple vapor absorption refrigeration systems is also introduced.

You'll explore the various components in a refrigeration system, focusing on condensers and their types. Additionally, the course covers non-conventional refrigeration systems such as thermo-electric, thermo-acoustic, and vortex tube refrigeration.

In the psychrometry section, you'll learn the basic concepts and properties, the development of psychrometric charts, and the functions of air washers. Key design parameters such as the sensible heat factor, bypass factor, and apparatus dew point are also discussed.

The course concludes with modules on the "Design of Air Conditioning Systems," where you'll study effective temperature, comfort charts, and comfort zones. You'll also learn about cooling load estimation and duct system design, complete with numerical examples to enhance your learning experience.

While there are no reviews yet, this course promises to provide a wealth of knowledge and practical insights, making it an invaluable resource for anyone looking to advance their understanding of refrigeration and air conditioning.
