Thermodynamic analysis and comparison study of two novel combined cooling and power systems with separators using CO2-based mixture for low grade heat source recovery

Transcritical CO2 power cycle is an available technology for low grade heat source recovery, but the low critical temperature (about 31℃) of CO2 working fluid restricts its practical application because it is hard to ensure the condensation for CO2 working fluid under the environmental temperature. In this paper, two novel combined cooling and power (CCP) systems with separators are proposed, namely the HCO2R (High concentration CO2 mixture...
