| Description: | This module aims to present a more comprehensive and rigorous treatment of
engineering thermodynamics and to prepare students to use and apply fundamental
thermodynamic principles in professional practice. The second law of
thermodynamics is examined and developed more fully and important concepts like
entropy generation and energy degradation principles are developed and applied to
more complex and detailed engineering systems. In light of the deregulation of the
energy sector, renewable energy technologies and local power generation
technologies are also examined. |

| Learning Outcomes: |
|---|
| On successful completion of this module the learner will be able to | - State the KelvinPlanck
and Clausius Statements of
the 2 nd Law and define a reversible and irreversible
process.
- Explain the physical significance of entropy,
entropy generation and exergy destruction
- Analyse vapour and gas power cycles from a 1 st
and 2 nd law perspective
- Describe and analyse vapour compression
and gas
refrigeration and heat pump cycles from a 1 st and
2 nd law perspective
- Analyse airconditioning
processes and apply the
theory to internal environmental control
- Apply energy management, provision auditing,
monitoring and energy recovery techniques to
typical industrial and commercial cases.
