低温余热驱动的热电复合系统优化设计
Optimization Design of a Combined Organic Rankine Cycle-Heat Pump System Driven by Low-Grade Waste Heat
摘要
Abstract
ABSTRACT:The system combined organic Rankine cycle (ORC) with heat pump cycle (HPC) was analyzed based on the 1st law of classical thermodynamics. Meanwhile the parametric trade-off was discussed to predict the performance for the combined system. It is found that under the typical waste heat conditions of the inlet temperature is 368.15K and mass flow rate is 1kg/s, the heat capacity of 27.56kW for the combined system will be obtained. And there is an optimal ORC-evaporation temperature for the maximum heating output, and the decrease of ORC-condensation temperature contribute to a reduction of heating output. In addition, the results show that the isentropic efficiency of turbine has a great impact on the heat capacity of the combined system.关键词
