  1. 1. Performance comparison between reciprocating and scroll compressor heat pumps with R600a refrigerant

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

    Author : CHRISTOFER KRONSTRÖM; [2021]
    Keywords : Heat pump; R600a; isobutane; scroll compressor; reciprocating compressor; piston compressor; Värmepump; R600a; isobutan; scrollkompressor; kolvkompressor;

    Abstract : A performance comparison of heat pumps using a scroll (Sanden) and a reciprocating (Bitzer) compressor was conducted experimentally. The refrigerant used was R600a (isobutane). READ MORE

  2. 2. Temperature effect on insert tool life in dry machining

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : William Hagberg; [2021]
    Keywords : Milling tool; Temperature; Wear; Simulation; Cooling; Heat sink; Insert;

    Abstract : This thesis work researched the temperature effects the insert tool life. This was examined through physical laboratory testing with designed milling tools and temperature simulations in ANSYS. The designed milling tools altered the temperature in the insert through external parameters like design and material. READ MORE

  3. 3. Master Thesis - Towards a Virtual Climate Chamber : A numerical study using CFD software

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Yuvarajendra Anjaneya Reddy; [2020]
    Keywords : CFD; Ansys FLUENT; Power Spectral Density; Turbulence quanitification; Digital Twin;

    Abstract : For each generation of electronic equipment there is a trend towards higher power den-sities. Increased heat generation is an undesired consequence that the thermal design unit in a company must handle. The goal of thermal design engineer/unit is to utilizethe same volume to more efficiently transfer more heat from the equipment. READ MORE

  4. 4. Field Measurements and Modelling Analysis of Integrated Ice Rink Energy Systems

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