从换热器的位置与数目、体现能量的梯级利用原则、减小传热温差、避免带有显著温差的传热过程及充分利用每一个温度等级的能量等方面，分析了循环冷却水非等温混合流程的不足，提出了湿空气透平（ＨＡＴ）循环冷却水等温混合流程，并对该流程的参数进行了优化选择，得出了ＨＡＴ最高热效率循环流程．还分析计算了该循环的热力学性能
From the heat exchanger position and the number of steps to reflect the use of energy principles, reduce heat transfer temperature, to avoid heat transfer process with significant temperature difference and make full use of each temperature level of energy, etc., analysis of the circulating cooling water isothermal In this paper, the isothermal mixing process of HAT circulating cooling water is proposed, and the parameters of the process are optimized and selected. The maximum thermal efficiency cycle of HAT is obtained. The thermodynamic properties of the cycle were also analyzed and calculated
