Abstract
The aim of the paper is to study the thermodynamic behavior of a non-conventional power cycle, named Carbon Carrier Cycle (CCC), which is expected to obtain interesting performance with low temperature heat source. The CCC may be regarded as derived from an absorption machine, where an expander replaces the condenser, the throttling valve and the evaporator. The working fluid is a mixture of CO2 and a proper absorber. In the paper, the thermodynamic model of this kind of cycles is described, and the results obtained considering Acetone as the absorber are discussed. A first performance comparison is then conducted with a more conventional Organic Rankine Cycle (ORC).
Highlights
In recent years, interest for the total efficiency of complex energy systems has grown considerably
The total efficiency of the system may be improved by adopting a bottom power cycle, which uses the low temperature heat as the input for producing some additional power
The aim of the paper is to evaluate the behavior and the performance expected for a non-conventional kind of cycle, named Carbon Carrier Cycle (CCC) [1]
Summary
Interest for the total efficiency of complex energy systems has grown considerably. In this perspective, the recovery of waste heat output flows may be quantitatively important and CHP is a wellknown and widely used approach. There are a lot of situations where the low temperature heat cannot be usefully consumed. In these cases, the total efficiency of the system may be improved by adopting a bottom power cycle, which uses the low temperature heat as the input for producing some additional power. The working fluid in the expander is pure CO2, or a mixture rich of CO2
