  1. 1. Data-driven modelsfor estimating heatpump powerconsumption

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

    Author : Monika Peskova; [2023]
    Keywords : heat pump; data-driven model; modelling; regression model; värmepump; data modell; modellering; regressionsmodell;

    Abstract : The number of installed heat pumps has been rapidly increasing in recent years, acceleratingthe decarbonisation of the heating sector. The impact of the increasing deployment of heatpumps on the grid can be evaluated with the help of models estimating the heat pumppower consumption. READ MORE

  3. 2. Electrically Assisted Turbocharger: Modelling And Control Strategy

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Vandor; Gabriel Ehlin; [2022]
    Keywords : EAT; VGT; VNT; Hybrid powertrain; electric turbocharger;

    Abstract : A major cause of CO2 emissions today is fossil fuel vehicles, and lowering these emissions is of key importance, resulting in increasing electrification and hybridisation nowadays. Turbochargers have been used for a long time to recycle exhaust gas heat losses to improve engine performance by compressing the intake air. READ MORE

  4. 3. 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

  5. 4. CO2 Refrigeration withIntegrated Ejectors : Modelling and Field Data Analysis ofTwo Ice Rinks and Two Supermarket Systems

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

    Author : SIMON FEHLING; [2021]
    Keywords : Vapor Ejector; Liquid Ejector; Field Data Evaluation; Modelling; Refrigeration; CO2; Ice Rink; Supermarket; Heat Recovery; Ångejektor; Vätskeejektor; Fältmätdata; Modellering; Kylteknik; CO2; Isbana; Livsmedelsbutik; Värmeåtervinning;

    Abstract : With the increasing importance of CO2 as natural refrigerant with low Global Warming Potential(GWP) ejectors have been used in a number of recent installations to recover expansion work atthe high operating pressures of these systems. In colder climates, this is particularly seen in combinationwith heat recovery due to the high compressor discharge pressures. READ MORE

  6. 5. Design and Optimisation of Internal Components for a Reciprocating Compressor Powering a Camless Valvetrain

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Filip Schander; Viktor Pott; [2021]
    Keywords : Topology; FEA; DMLS; Piston; Connecting Rod; Crank Mechanism; Crank Balancing; Technology and Engineering;

    Abstract : Freevalve AB develops camless valvetrains for internal combustion engines using pneumatic and hydraulic systems. An air compressor is used to generate pressure in the pneumatic system. To further increase efficiency of the Freevalve system, a new compressor tailored to its purpose, is being developed in house. READ MORE
