MJ112V Energy Efficient Components, systems and methods 3.0 credits

The course addresses engineers and others who work with technical infrastructure in industry, municipalities, the real estate sector etc., who need arguments to choose energy-efficient devices, equipment and control methods that ensure high energy efficiency for a long time, even if that may require a larger initial investment.

The course covers the following:

• An overview of the importance of choosing highly efficient equipment, particularly in installations that should handle energy flux during a long period of operation.
• Examples of highly efficient products (e.g. electric motors, pumps, fans, heat pumps, etc.
• Examples on automation and control methods and efficient operating strategies.
• Combination of equipment for systems delivering multiple energy and energy related services (polygeneration).
• LCA comparison of investment cost and operating cost.
• Case studies including a study visit to an industry or an infrastructure facility.
• A lab that visualises energy savings with highly efficient equipment.

After passing the course, the student should be able to

1. Explain the importance of choosing energy-efficient components and merging them into energy-efficient systems by means of methods for achieving high energy efficiency.
2. Analyse the economy over a life cycle for different systems that have comparable technical performance.
3. Evaluate and compare the cost for investment and the operation/maintenance cost for different systems with comparable technical performance.
4. Dimension and evaluate an energy-efficient system for energy supply and operation in a case study.

Technical knowledge at upper-secondary level.

Basic knowledge about Sweden's energy supply.

Basic knowledge in electrical engineering (Voltage, current, power, Ohm's law etc.)

Basic knowledge in thermodynamics (temperatures and flows, principles of thermal exchange etc.)

If the course is discontinued, students may request to be examined during the following two academic years.

• LAB1 - Laboratory work, 1.0 credits, grading scale: P, F
• QUI1 - Quiz 2, 0.5 credits, grading scale: P, F
• QUI2 - Quiz 2, 1.0 credits, grading scale: P, F
• STU1 - Study visit 1, 0.5 credits, grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Passing the course requires, in addition to the above, that the student participates at least 80% of the teaching components.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
