针对空气冷却除湿过程中室内湿度控制不足的问题，分析了影响空气热湿处理设备显热比的主要因素，对余热排除的有效性进行了计算分析，提出有效控制温湿度的途径。结果表明：采取降低机器露点温度和增加冷却盘管排数的方法降低显热比不可取，实际制冷系统的有效度为69．4％，接近卡诺循环的效率，但是整个系统的排除余热的效率却很低，仅为15．1％；采用分级主动除湿的方法，对提高制冷系统的除热有效度、提高能量利用效率具有实际意义。

For the under control problem of humidity in the air cooling and dehumidifying process, the paper analyzes the principal elements impact on the Sensible Cooling Ratio （SCR） for air handling process equipment, gives some analysis and calculation on excess heat removal efficiency, proposes an effective solution for heat-moisture control. It turned out that, the method to lower SCR by decreasing Apparatus Dew Point （ADP） temperature and adding cold coils to be not desirable. The system dehumidification efficiency is only 15.1%, even though it seems that the actual efficiency is 69.4%, closed to Carnot cycle. It is practical significant to improve system heat eliminating efficiency and energy utilizing efficiency by Sub-level and Active dehumidifying method.
