利用有限时间热力学逆循环的热力学完善度计算方法计算分体式空调器的有限时间热力学完善度,并与实测数据进行比较。结果表明,当室外温度在30～38℃范围内时,分体式空调器的计算EERm与实测EERt的相对误差在25%以内。指出有限时间热力学理论可为合理评价分体式空调器的能效提供参考。
Finite time thermodynamic improvement of split air conditioners was calculated by thermodynamic improvement method of finite-time thermodynamic inverse cycle, and compared with the measured data. The results show that when the outdoor temperature is in the range of 30 ~ 38 ℃, the relative error between the calculated EERm and the measured EERt of the split type air conditioner is within 25%. It is pointed out that the theory of finite-time thermodynamics can provide a reasonable reference for evaluating the energy efficiency of split-type air conditioners.
