摘　　要：为了建立评价冷水机组和水源热泵的EER或COP等能效指标的公共平台,提出了热力学完善度的分析方法,并计算了我国的房间空调器、冷水机组和水源热泵等制冷装置的热力学完善度的数据范围。大多水冷产品的热力学完善度在0.3至0.5之间,高效产品可以达到0.6,但风冷产品热力学完善度在0.2左右,空气源热泵热水机等介于两者之间。热力学完善度可用于同类产品或相似产品在不同工况下的性能比较。分析可见热力学完善度表征着当前产品设计制造的综合水平,是制定相关产品能效标准的限定值、节能值及能效等级的依据。To set up a platform for evaluating energy efficiency of water chiller and water source heat pump systems with EER or COP, the method of the second thermodynamic perfectibility was introduced. The range of thermodynamic perfectibility of room conditioners, water chillers and water-source heat pumps were calculated. The results show that the thermodynamic perfectibility of most water chillers is in the range of 0.3 to 0.5, the efficient products can reach 0.6, but the thermodynamic perfectibility of air to air products is about 0.2, and the thermodynamic perfectibility of air source heat pump water heaters is between water chillers and air to air products. The thermodynamic perfectibility is a useful index for the performance comparison of same or similar production in difference working conditions. The thermodynamic perfectibility analysis indicated that it characterizes the design and manufacturing level of products at present, and can be important foundation for the decision of minimum allowable performance, energy conservation performance and energy efficiency grade of energy efficiency standards for related products.
