6. Increasing the value of household appliances by adding a heat pump system
Sammanfattning : Historically, domestic tasks such as preparing food and washing and drying clothes and dishes were done by hand. In a modern home many of these chores are taken care of by machines such as washing machines, dishwashers and tumble dryers. LÄS MER
7. The Compression/Absorption Heat Pump Cycle - System Simulations
Sammanfattning : From the results presented in this thesis it is clear that the compression/absorption heat pump cycle offers several advantages over other types of heat pumps. In many cases it gives a higher or equally high COP compared with the single-fluid compression heat pump but also the smaller SCD (i.e. LÄS MER
8. Improving the performance of combined heat and power plants through integration with cellulosic ethanol production
Sammanfattning : Today’s biomass-fired combined heat and power (CHP) plants have surplus heat production capacity during warmer times of the year. In order to allow them to increase their electricity production, it is essential to find a use for the surplus heat. LÄS MER
9. Compression/Absorption cycles for large heat pumps - Systems simulations
Sammanfattning : The compression/absorption cycle can, in many situations,give an improved performance compared to the single-fluidcompression heat pump. Also other advantages can beachieved such as the possibility to use an already knownrefrigerant within a new temperature range. LÄS MER
10. Novel cycles using carbon dioxide as working fluid : new ways to utilize energy from low-grade heat sources
Sammanfattning : This licentiate thesis proposes and analyzes three carbon dioxide novel cycles, namely: the carbon dioxide transcritical power cycle, the carbon dioxide Brayton cycle and the carbon dioxide cooling and power combined cycle. Due to the different characteristics of each cycle, the three cycles are suitable for different applications. LÄS MER
