6. An on-engine twin-scroll turbine performance estimation
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : In this study the main objective was to estimate the instantaneous turbine shaft power and turbine efficiency of a turbocharger mounted on a 6-cylinder 13 literheavy-duty diesel engine. The work was carried out at Scania CV AB in Södertälje, Sweden from January to June 2015 as master thesis under the division of Internal Combustion Engines at the Royal Institute of Technology KTH, Stockholm, Sweden.

7. Experimental evaluation of air-to-water propane heat pumps with 40kW heating capacity
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : This thesis presents the experimental work on testing the seasonal performance of a 40 kW air-to-water propane heat pump, as a part of the research project Next Heat Pump Generation working with Natural fluids (NxtHPG) that has been carried out in ‘Applied thermodynamics and refrigeration Division’ in the department of Energy Technology, KTH. The thesis work involves three parts: preparation of the HP unit test rigs, experimental campaign and the evaluation of test results. LÄS MER
8. Experimental analysis of variable capacity heat pump system equipped with vapour injection and permanent magnet motor
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : This study analyzes the performance of variable capacity heat pump scroll compressor which is equipped with vapour injection and permanent magnet motor. Refrigerant used in the system is R410A. The study is divided in two phases. In first phase, tests are carried out for heat pump without vapour injection. LÄS MER
9. Dynamisk Analys av scrollkompressorn
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Det svenska företaget Thermia använder scrollkompressorer från det amerikanska bolaget Copeland i sina värmepumpsystem. Trots den betydande ljudminskning som scrollkompressorer ger jämfört med andra kompressorer är ljudtrycksnivån fortfarande 56 dBA. LÄS MER
10. Vibrationsdämpning av värmepump
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Thermia Värme AB is one of the market leading manufactures of heat pumps. In order to maintain this position, the company wants to improve the vibration characteristics of their products. The aim of this thesis is to develop product design changes that lead to a reduction of vibrations in the heat pump Thermia Diplomat 8. LÄS MER
