Assessing sustainable operational conditions of a bottoming organic Rankine cycle using zeotropic mixtures: An energy-emergy approach [PDF]

open access: yesHeliyon, 2023
In this work, an Organic Rankine Cycle system is used to produce electricity from the waste heat of an internal combustion engine (ICE). The toluene, and cyclohexane, are the selected pure fluids to be compared with the zeotropic mixtures.

Continuous tuning of ejector parameters via zeotropic component migration for optimising high-temperature heat pump [PDF]

open access: yesCommunications Engineering
As the temperature lift increases, heat pump performance declines due to rising throttling losses in expansion valves. Ejectors present a promising alternative, enabling power recovery from the throttling process.

Experiment and Criterion of Incomplete Condensation of Zeotropic Mixtures

open access: yesZhileng xuebao, 2007
Incomplete condensation may occur for zeotropicmixtures used. Experiments for two zeotropic mixtures were conducted and the variation of heating capacity and COP with the increase of water flow rate in a condenser was obtained to confirm the possibility ...
