Module Description:This module aims to equip the student with the knowledge and skills to reduce thermal energy demand of the major energy usage systems such as HVAC, steam and compressed air plant, recover energy from thermal systems and evaluate thermal energy demand reduction proposals from thermodynamic and financial perspectives.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Describe how to undertake performance optimization of ventilation, hot water, heating, process steam, refrigeration, compressed air and air conditioning systems.
LO2 Carry out basic calculations in the sizing and performance evaluation of aspects of modern HVAC systems
LO3 Describe the layout and the functioning of each of the elements of waste heat recovery systems.
LO4 Calculate heat transfer coefficients, heat exchanger effectiveness, heat transfer rates and sizes for commonly used industrial heat exchangers.
LO5 Carry out a thermal and financial analysis of proposed retrofitting and replacement schemes.
LO6 Describe of some thermal energy storage technologies used in HVAC systems and analyze the sizing of a typical ice-storage application
