TMES12, Energy Systems, 6 ECTS
For: ENV
Prel. scheduled hours:38 Rec. Self-study hours:122
Area of Education: Technology
Subject: Mechanical Engineering
Advancement level: D
Aim:
The aim of this course is to present an international system perspective on combined energy
systems of energy suppliers and energy users. The course describes sustainable energy
systems, the energy systems effects on the environment and climate changes.
The most important intellectual development a student will undertake is:
• Present energy systems interrelations and system theory
• Describe energy resources, sustainability and climate changes
• Describe the design of a heat and power generation plant and distribution of district
heating
• Describe the development and design of national and regional as well as municipal
energy systems
• Demonstrate the energy balance of energy use and energy supply
Prerequisites:
Basic courses in thermodynamics.
Supplementary courses:
Building energy systems, Energy systems analysis, Industrial ecology, Industrial energy
systems, Integrated management systems, Impact assessment and project appraisal,
International energy markets, Resource efficient products.
Organisation:
The course is given in the form of lectures and seminars. The course also contains two project
works and a visit at a combined heat and power plant.
Course contents:
The course consists of an opening section, three subject fields, and a closing section. The
three subject fields are Energy Supply (I), Sustainability (II), and Energy Use (III).

The course starts by an opening section where the aim, contents, literature and project work of
the course are presented. In the opening section an introduction to energy system is presented
and a demonstration of system theory by explaining system definition, system boundaries,
case study research and energy systems and the environment
Subject field I present production and distribution of steam, hot water, chilled water, and
power. The system of combined heat and power plants, steam power plants, gas turbine plant,
and vapor compression/absorption cycles are described. The design criteria for district heating
and district cooling are illustrated.
Subject field II demonstrates the world’s potential, and techniques, of supplying sufficient
amounts of renewable energy for sustainable energy systems. Renewable energy sources,
climate changes and resource and sustainability are illustrated.
Subject field III represents energy use. Sweden’s energy balance and the energy balance of
the worlds, industrial energy use, and energy use in building are demonstrated.
The combined sustainable energy systems of energy supply and energy use are demonstrated
in subject field IV. The totality of the different subject fields is presented in municipal,
regional and national energy systems.
On basis of all course items the course ends by explaining the future energy system by
demonstrating how to design sustainable energy systems of energy suppliers and energy
users.
The figure below illustrates the main contents in the course and how the different subject
fields are connected.
