Summary

In recent decades we witness a surge in electricity consumption rates, which escalates carbon dioxide emissions and increases global warming and other deleterious environmental impacts. Heat powered cycles are of great interest as they enable reduced electric power consumption. Ongoing research on thermally driven sorption compressors is being conducted in our research laboratory. In this research phase, a multi-stage sorption compressor for carbon dioxide is numerically investigated using a previously developed model. The model is dynamic and fully parametric, allowing for the analysis of nearly any cylindrical sorption cell with any heating and cooling method under various operating conditions. Multiple designs of adsorption cells and different heating and cooling methods have been evaluated to investigate sorption compressors. This paper presents four designs of sorption cells which we consider, a validation of the numerical model with carbon-dioxide, and numerical results a three-stage sorption compressor, which aims to compress carbon-dioxide from 5 MPa to 20 MPa.
