1. District Heating Substations. Performance, Operation and Design
Sammanfattning : This thesis work is concerned with the efficient layout and operation of substations, i.e. those district heating (DH) system units which connect the network and internal building heating systems, such as radiator heating systems and domestic hot water distribution networks. LÄS MER
2. District Cooling – Towards Improved Substation Performance
Sammanfattning : The global cooling demand in buildings is rapidly increasing and to supply this demand, district cooling is one solution. However, many district cooling systems suffer from low delta-Ts (receiving low return temperatures from the buildings connected to the system). LÄS MER

Sammanfattning : .... LÄS MER
4. Low-temperature based thermal micro-grids: operation and performance assessments
Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER
5. Spot the difference! : On the way towards automated fault handling in district heating buildings
Sammanfattning : This thesis focuses on how district heating utilities may work with fault handling in customer installations as a tool to reduce their return temperature levels. Reduced return temperatures would make it possible to improve the efficiency of the district heating systems and decrease their environmental impact. LÄS MER
