相对节能率从33.2%提高到39.0%。

Abstract

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 absorption 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 improvement 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%.
