Thermodynamics Basics: Gas Dynamics, Psychrometric Analysis, Refrigeration Cycle and HVAC Systems

COURSE NO: M08-006
Thermodynamics Basics: Gas Dynamics, Psychrometric Analysis, Refrigeration Cycle and HVAC Systems
Course Highlights

In this online engineering PDH course, you will be introduced to thermodynamic and physical performance of gases flowing at high speed, application of SFEE, Steady Flow Energy Equation, to high speed gas flow scenarios, and determination of exit speed of superheated gas in high speed flow nozzle scenario.


You will also be introduced to psychrometric analysis of HVAC system performance. You will be familiarized with fundamental psychrometrics terminology, concepts, analytical techniques, methodology and strategies. All discussion is supported and illustrated by numerical examples and a comprehensive case study.


Fundamentals of refrigeration cycle are explained. Concepts, terminology and thermodynamic principles associated with refrigeration cycle are discussed and illustrated through pressure-enthalpy and temperature-entropy diagrams. A capstone case study, involving a DuPont ® HFC-134a based refrigeration cycle, serves as an illustration of a practical refrigerant cycle, such as those employed in chillers and HVAC evaporator/heat exchangers.


This 8 PDH online course is applicable to engineers of all disciplines, as well as technicians, facilities managers and executives who are not intimately familiar with thermodynamics principles and practices.
