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. Realise the Potential! : Cost Effective and Energy Efficient District Heating in European Urban Areas
