Objectives
The general aim of the course is that the student acquires knowledge within the field of district heating technology with respect to technical, systemic, economic, environmental as well as research related aspects.
Following successful completion of the course the student should:
Knowledge and understanding
- account for the function of district heating systems with respect to technical, economical, and environmental aspects
- sescribe the fundamental idea of district heating systems with respect to resource efficient management
Skills and ability
- apply a variety of energy technology methods in problems relating to district heating systems
- analyze the different interacting parts of the district heating system in terms of technology, function, and economy
Judgement and approach
- assess technical, economical, and environmental conditions for district heating systems
- assess district heating systems efficiency in relation to other parts of the energy system
Content
- The role of district heating within the energy system and its benefits
- Building heat demands (space heating and domestic hot water)
- Distribution losses in district heating networks
- Heat load in heat supply units
- Heat generation and heat recovery from combined heat and power (CHP) plants, waste incineration, industrial excess heat, geothermal, heat from difficult fuels, and heat storages
- The environmental impact from energy conversion in district heating systems
- Heat distribution with different piping technologies
- Substations with connection principles, heat exchangers, and heat metering
- System functioning with respect to pressure loss, pressurization, combined temperature and flow control including the overall control system with four independent control loops
- Economy with distribution cost, heat supply optimization, cost allocation of joint production and the pricing methodologies
