Reinforcement of the concepts seen previously (second step)

The second step of this course corresponds to the reinforcement of the concepts seen in the first step, with theoretical supplements on exergy and heat exchangers, the study of the variants of basic cycles, combined cycles and cogeneration (approximately 8 hours of work, excluding supplements).

At the end of this stage, learners should have understood:

• the typology and calculation principles of the core components of Thermoptim (including their technological characteristics)
• for each example, the origin of the irreversibilities and the axes of improvement
• the principles of calculation of the exchangers, in dimensioning and in off-design mode
• the form of the cycles of the examples in the diagrams (h, s), (xh, h) and (xh, s)
• the influence of the main constructive parameters on the performances of the main technologies of energy conversion (TEC)
• the influence of the main external demands on the performances of the main TCEs
• the environmental impact of the main TCEs
• the principles of establishing exergy balances

Basics of thermodynamics

• Exergy balances

  This session shows how to draw up exergy balances in an open system

Regeneration gas turbine, exercise on exergy balance

• Thermodynamics of heat exchangers

  This session discusses heat exchangers and shows how to build them in Thermoptim

• GT exercise with combustion

  This exercise extends the exercise on compression and expansion (Sessions S21_En and S22_En). First, the exergy balance of the gas turbine studied above is drawn up using the spreadsheet presented in S6_En, which we recommend you to refer to. Then, we insert a regenerator in the machine, which allows to increase the performances

extraction and reheat cycle, exercise on exergy balance

• Exercise extraction and reheat cycle steam cycle

  This exercise extends the exercise of the S26 session by adding a 15% extraction and a reheat at 540 ° C

• Exercise exergy balance of steam cycles

  This exercise extends the exercises on steam cycles (Sessions S26_En and S27_En) The exergy balances of the two cycles studied above are drawn up, using the spreadsheet presented in session S06_En, to which you should refer to

Compression refrigeration cycles, exercises, exergy balances

• Exercise exergy balance sheets refrigeration cycle

  This exercise extends the exercise of session S31_En by drawing up the exergy balances and by studying the influence of the external temperature on the performances of the machine

• Exercise on heat pump

  In this exercise, we start by modeling a ground-water heat pump, then we draw up an exergy balance, and we size its evaporator.
