|Abstract:||While organic Rankine cycles have been widely used for power generation using low grade thermal energy, Brayton cycles have not been considered feasible because the work required to compress the gas nearly compensates the turbine work output. However, if the low grade energy can be used for thermal compression of the working fluid, it may be possible to gainfully operate the Brayton cycle. With this in mind, a solid sorption based Brayton cycle is proposed in this paper. R134a, CO2, R507a, propane, R32 and R410a with activated carbon as sorbent, were considered in this proof-of-concept study due to the ready availability of adsorption data. Even though the thermal efficiency is low (|
