2. 1. Thermodynamic Cycles using Carbon Dioxide as Working Fluid : CO2 transcritical power cycle study

   Author : Chen Yang; Lundqvist Per; Carlos Infante Ferreria; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. READ MORE

4. 2. Novel cycles using carbon dioxide as working fluid : new ways to utilize energy from low-grade heat sources

   Author : Yang Chen; Per Gunnar Lundqvist; Mats Westermark; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal energy engineering; Termisk energiteknik;

   Abstract : 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. READ MORE
