【摘要】 在热泵系统仿真模型的基础上,结合典型建筑物的全年负荷预测,提出了热泵系统全年季节性能优化的理念,定义了热泵全年性能系数APF,并以此为优化目标函数,换热器面积比为优化变量,研究在压缩机开停控制方式下系统的优化匹配,并与以HSPF、SEER和EER为优化目标的优化计算进行对比,结果表明,采用APF作为优化目标具有更加真实客观的节能效果。更多还原

【Abstract】 The annual performance factor(APF) optimization of water-water heat pump was presented.Based on the building load in a whole year,the APF of a heat pump was defined and used as the optimization function,with the area ratio of heat exchanger as the optimization variable.The optimization mathematical models for the on-off control scheme were set up to calculate the APF to study the optimal design and matching between different components.Comparison with different optimization designs with HSPF,SEER,and EER,the APF optimization is nearer to the reality.更多还原
