This course is the second in a 4-course series.
- Part 1 is based on understanding thermodynamic concepts and using pressure enthalpy charts.
- Part 2 builds onto part 1 but uses thermodynamic software instead of pressure enthalpy charts for analysis and goes into additional depth.
- Part 3 (consisting of Parts 3A and 3B) builds on parts 1 and 2 to apply thermodynamics to understand air conditioning and refrigeration systems from ¼ hp size units to 300,000 hp size units. Part 3A focuses on pure substances and mixed refrigerant liquefaction systems. Part 3B focuses on nitrogen expansion liquefaction systems.
Note that each course in the series is a “stand alone” course. It is not necessary to first complete Parts 1 and 2 in order to study Parts 3A & 3B, provided the learner already possesses the prerequisite knowledge needed.
This course (Part 2) introduces the learner to using thermodynamic software instead of charts for performing thermodynamic analyses. Such software is much more time efficient, accurate and flexible. Thermodynamic software allows the learner to dive deeper into their understanding of the field of thermodynamics. In this part, we will build on the learning of Part 1 and expand our ability to deal with mixtures rather than solely the pure fluid of methane.
In Part 2, a major focus is made on broadening the scope of understanding thermodynamics. Pump and compressor efficiencies and understanding many facets of thermodynamics that would not be adequately explained without using thermodynamic software are explained.
