The aim of the course is to give a good overview of the topic district heating and district cooling and to convey knowledge about the district heating and district cooling technology and its role in the energy market and in the energy system. Main subjects discussed in the course are: Introduction - History, Concepts, Heat and Cooling Markets. Heat and cooling needs. Production of heat and cold. Environmental impact and benefits. Distribution Technology. Customer installations. Economy and future challenges.

The course includes lectures, written tests, seminars, group exercises, and an optional exam for upper grades of 4 and 5.
The course includes technical history from a district heating perspective, an overview of heating and cooling markets, the appearance of heat and cooling needs in different sectors and activities and parameters that affect the load profile for heat and cooling (season, weather, occupation, insulation rate and thermal losses). Furthermore, it is discussed how the heat and cold are produced; environmental effects of district heating and district cooling at local, regional and global level are treated with regard to the fuels and energy sources used in production. Various piping techniques and components in the networks and installation techniques for different types of pipes are reviewed. Technology for district heating and district cooling plants is treated in the course as well as metering and billing of heat and cold. The district heating network's system function is discussed, as is the development of network structures. The course also explains how the operation of district heating is controlled by pressure, temperature and energy demand, as well as the different conditions that affect operating conditions. It also gives insight into important conditions for pipe diameter design and flow rate selection. District heating business concepts, financial conditions and basis for pricing are handled in the course. Furthermore, organization, ownership and legislation is included and discussed, as well as the role of district heating in a future energy system.
The theoretical concepts and basis of the course is deepened in three group assignments and three seminars with laboratory and interactive elements.
Assignments
The first assignment aims at giving students greater understanding of heat and cooling loads and load profiles. The second exercise aims at giving students skills in network dimensioning and understanding of thermodynamic conditions. The third assignment, which is a poster exercise, allows students to engage in reading and evaluating different research reports and to produce their own scientific poster and present it at a poster session. The exercise is aimed at broadening the contents of the course book, giving students insight into current research on district heating and district cooling, and to practice the students' oral and written ability to explain relevant concepts and theories. To the posters session, representatives from district heating companies are invited to attend. This gives the students a connection to future potential employers and an anchoring in the practice of district heating and cooling. One guest lecture is given by a representative from a local district heating company which also gives students a connection to practice.
Two consultations are included for supervision of exercises.
Seminars
The three seminars aim to give a deeper knowledge about market conditions, production conditions and regulation of heat and hot water at the customers. The first seminar about the district heating market deepens the understanding of district heating business and theories behind pricing. In the second seminar, the understanding of heat production conditions is deepened by simulation of load conditions. The third seminar will deepen understanding of how regulation of customers' district heating substations is done through simulation. The seminars are conducted in the form of ‘flipped classroom’ where the student is expected to prepare by reading the prescribed literature (partly in the course book and partly in supplementary literature available on the course platform).
Written tests
The student's understanding of the course content is examined by three multiple choice questions test (as well as in the optional written exam for upper grade).
Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: The examination is based on individual as well as on group work. For the grade 3, all obligatory assignments (individual or in group) have to be satisfactorily fulfilled. For higher grade, a written exam is required.
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
The number of participants is limited to: No
