| Module Description: |
This module examines the integration of industrial-scale thermal systems on a site or in a district, with a view to achieving the optimum energy consumption. |
| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| LO1 |
Conduct energy balances on single process units, without reaction, or with combustion. |
| LO2 |
Conduct energy balances on systems of thermal units |
| LO3 |
Devise appropriate control strategies to thermal energy generators and consumers |
| LO4 |
Apply the concept of Pinch Technology to heat and power networks to identify the major factors that affect the overall performance of these networks. |
