1. 1. Potential benefits of implementing demand response into Vattenfall’s district cooling grid in Uppsala, Sweden

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Magdalena Guerrero Wretljung; [2023]
   Keywords : ;

   Abstract : Lately, there has been an increased cooling demand in Vattenfall’s district cooling (DC) network in Uppsala, Sweden. This especially occurs on warmer summer days, during so-called peak demand periods, where there is limited cooling capacity combined with limited distribution capacity in the network. READ MORE

3. 2. Normalization of Cooling Demand in Buildings, development, and evaluation of methods

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Xingtong Wu; [2022]
   Keywords : ;

   Abstract : Because of the increasing demand for indoor thermal comfort and the better insulation performance of building envelopes, cooling demand is an increasingly important part of building energy consumption despite the cold climate in Stockholm. Finding a way to normalize cooling demand to climatic conditions will help better energy audits to improve the building performance to achieve energy-saving. READ MORE

4. 3. Optimization of district coolingsystems : A case study in a Swedish industrial setting

   University essay from KTH/Energiteknik

   Author : Siri Sinimaa; [2022]
   Keywords : ;

   Abstract : Energy utilization as well as heating and cooling specifically constitutes a large share of the energy consumption in the EU. Reducing greenhouse gas emissions in this sector is thereby of importance to mitigate climate change and fulfill the criteria stated by the Paris Agreement of limiting the increasing global mean temperature to 1.5 °C.

5. 4. Data center cooling solutions : A techno-economical case study of a data center in Sweden

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Joel Sjökvist; Fredrik Magnusson; [2022]
   Keywords : Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

   Abstract : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. READ MORE

6. 5. ManagementPractical Aspects of Aqua Ammonia as Secondary Refrigerant in Ice Rinks

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jacqueline Pierri; [2021]
   Keywords : Ice rink; secondary refrigerant; refrigeration; refrigerant management; secondary fluid; natural refrigerant; aqua ammonia;

   Abstract : The transition from fluorinated gases to natural refrigerants could be key to reducing the impacts of climate change. Ice rinks are energy-intensive buildings, with large heating and cooling demands. The pumping power required to move the secondary refrigerant typically accounts for a sizable amount of the energy use of the refrigeration system. READ MORE
