摘要：
In this paper, a combined heat and power system which is composed of flat plate solar collector, organic Rankine cycle (ORC) and heat pump is proposed, organic fluid R245fa and refrigerant R22 are used respectively as the working fluid of ORC and heat pump cycle.The combined system is simulated by process simulation software gPROMS, the effect of six key parameters on the system performance are analyzed based on net power output, power generation efficiency and CHP efficiency of the system.Results show that there is an optimal flow rate of heat transfer oil and the condensation temperature of refrigerant which let CHP efficiency get maximum value.The combined system is compared with the traditional solar organic Rankine cycle, the results show that CHP efficiency of the combined system is 3.7% higher than that of the ordinary solar ORC when the solar radiation is 1000 W/m2. © 2017, Chemical Industry Press Co., Ltd..
