1. Design and evaluation of stationary polymer electrolyte fuel cell systems
Sammanfattning : The objectives of this doctoral thesis are to give a basisincluding methods for the development of stationary polymerelectrolyte fuel cell (PEFC) systems for combined heat andpower production. Moreover, the objectives include identifyingprerequisites, requirements and possibilities for PEFC systemsproducing heat and power for buildings in Sweden. LÄS MER
2. Approaches to energy efficient building development : studying under Chinese contexts
Sammanfattning : This thesis presents a general description of approaches to energy efficient building development under Chinese contexts. The purpose of the work is to discuss how Chinese building development can be approved from an energy saving perspective. Building development is a complicated process that relates to many stakeholders’ interests. LÄS MER
3. Exergy Analysis in Buildings : A complementary approach to energy analysis
Sammanfattning : Though mandatory to be pursued, improved energy efficiency is not the only target to reach. The quality of energy has to be assessed as well. Most of the overall energy use in residential building is for low temperature heat, i.e. LÄS MER
4. Efficiency and Mixing Analysis of EGR-Systems for Diesel Engines
Sammanfattning : The reduction of fuel consumption and the reduction of toxic emissions are the main goals of research and development in the area of internal combustion engines. The use of exhaust gas recirculation (EGR) to come further in that direction is today an established method for diesel engines. LÄS MER
5. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation
Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER
