摘　　要：介绍制冷与热泵产品的热力学完善度的原理和计算方法,比起常规应用的EER或COP性能参数,热力学完善度具有稳定性、可比性、相对性、统计性和合理性等特点,可用于同类产品或相似产品在不同工况下的性能比较。文中给出了热力学完善度的应用实例。The principle and calculation of thermodynamic perfectibility of refrigeration and heat pump production is introduced.Comparing with the traditional performances such as EER and COP,thermodynamic perfectibility has five features:stability,comparability,relativity,statistics and rationality,and it is useful for performance comparison of same or similar production in difference working conditions.Several typical examples are stated too.
