Aiming at enhancing the fossil energy utilization efficiency,a combined cooling and power (CCP) system for high efficient utilization of waste heat was proposed,combing with Rankine cycle and absorption chiller.This system does work to generate power through Rankine cycle,and recover condensate heat from the Rankine cycle and low pressure steam heat from a heat recovery steam generator (HRSG)by the ab-sorption chiller,thus to supply the cooling load and realize deep cascade utilization of the system waste heat.The thermodynamic performance of the CCP system was investigated.The results show that,with im-provement in waste heat cascade utilization degree of the system,the total energy utilization ratio increased from 52.4% to 91.0%,and the primary energy saving ratio (PESR)was increased from 33.2% to 39.0%.
