ABOUT THE COURSE

This course caters, mainly, to Engineers, Technicians and Facilities Managers who are not intimately familiar with thermodynamics principles and practices. Through this workshop, attendees are expected to learn or refresh fundamental principles and concepts of thermodynamics in a simple, easy to understand, format; catalyzed by live discussion on the topic in class. This workshop/course illustrates application of thermodynamic principles in practical industrial, commercial and residential applications. This course demonstrates how to analyze and solve various types of practical thermodynamic problems through multiple case studies. In this program, laws, equations, graphs, charts, tables and diagrams, pertaining to various thermodynamics concepts, are covered and utilized in the analysis and solution of the case study problems. A detailed study for psychrometry, psychrometric chart and their role in HVAC analyses is undertaken. This seminar is themed after Prof. Rauf’s book titled “Thermodynamics Made Simple.”

Learning Objectives

1. Understand the concept of heat energy and its correspondence with work and other forms of energy in the thermodynamics realm.

2. Understand the concept of specific heat and its role in calculation of heat associated with change of temperature in thermodynamic systems.

3. Understand conversion of energy from fuel form to heat, from heat to steam, from steam to work, and work to electricity – illustrated through a comprehensive, multistage, case study.

4. Learn about the concepts of enthalpy, entropy, internal energy, work, and power.

5. Understand the difference between sensible and latent heats, and their role in the change of phases of substances.

6. Gain understanding about the role of saturated and superheated steam tables in thermodynamics system analysis and determination of the phase of water.

7. Understand the practical significance and the difference between various thermodynamic processes, i.e. isobaric, isenthalpic, isentropic, adiabatic, isochoric, isometric, isothermal, etc.

8. Learn about Mollier’s diagram, the psychrometric chart and their applications in design and optimal operation of HVAC Systems.

9. Understand the refrigeration cycle and get insight into refrigeration process through review of pressure-enthalpy performance of DuPont® 134a refrigerant.

10. Get an appreciation of energy conservation and process optimization value offered by direct digital, or automated, control of HVAC Systems. Learn about the typical architecture of automated HVAC systems.

Why you shouldn’t miss this course – How this course can benefit your organizations, what is unique about this course:

1. Does the term thermodynamics sound intimidating to you? After this workshop, it shouldn’t. Your instructor, Professor Rauf will explain those elusive, abstract, and hard to understand thermodynamics concepts, principles and analytical techniques in an easy to understand fashion.

2. How often do you get an opportunity to attend a workshop or seminar conducted by the author of a text book on the subject matter? In this workshop, you will have the opportunity to learn from and interact, live, in person, with Bobby Rauf, author of Thermodynamics Made Simple for Energy Engineers. (A copy of the book available at additional cost)

3. Do you manage mechanical engineers, thermodynamics experts, or HVAC engineers, but you are rusty in thermodynamics concepts, analytical techniques and design considerations? This workshop provides you the opportunity to brush up on that knowledge and those skills, so that you can understand the challenges confronted by your subordinates and colleagues more clearly, and can make informed objective decisions.

4. Have you ever wondered how those power generating plants can take water and produce electricity out of it? Through an illustrative case study, your instructor will show you how to harness electrical power starting with sub-zero ice.

5. If you are unfamiliar with, or are rusty on the use of psychrometric charts, and would like to refresh yourself or learn how psychrometric charts are used to analyse HVAC performance and design, then this workshop is a must for you.

6. If you are an engineer who has little or no thermodynamics background, then, this workshop will serve as an excellent opportunity to cross train and enhance your knowledge about a subject that your colleagues, around you, might be more familiar with.

7. Are you in a facilities management or maintenance management role? Do you wince every time you confront the high energy bills associated with the operation of those large chillers and refrigeration machines? Do you feel perplexed and feel as if you lack sufficient knowledge to understand the root cause behind expensive repairs associated with those large chillers and refrigeration machines? Then, this workshop will help you lift the veil of complexity associated with refrigeration cycle and you will get an opportunity to see through the intricacies of refrigeration cycle through a review of DuPont ® 134a pressure-enthalpy graph.

8. Remember those saturated and superheated steam tables? Perhaps you were never introduced to them? Not to worry. By the end of this workshop, you will gain appreciation for the role of steam tables in assessing the transformation of phases and the conversion of heat energy into work and power.

9. Last, but not least – If you are not a licensed Professional Engineer, but aspire to be one, and if you are rusty in the fundamentals of thermodynamics concepts and principles, then this two (2) day course could serve as a “warm-up” on some of the thermodynamics mechanical engineering principles, concepts and problem analyses techniques.
