空气处理机组的冷却盘管特性研究
Cooling coil characteristics of air handling units
摘要：
空气处理机组实际运行过程中的参数变化对换热特性有较大影响。通过模拟计算得出了各种工况条件下的一次回风定风量空气处理机组的换热特性变化规律和变风量空气处理机组的换热特性。结果表明，冷却盘管入口空气参数和入口水温的变化对定风量空气处理机组的换热特性影响显著，而冷却盘管入口空气参数对变风量空气处理机组几乎没有影响。

Abstract：
Dynamic changes of running parameters have a great impact on the heat transfer characteristics. Simulates and analyses the dynamic heat transfer characteristics of cooling coils of air handling units used in the constant air volume (CAV) system with primary air and the variable air volume (VAV) air conditioning system. The results show that the heat transfer characteristics in the CAV system are noticeably influenced by inlet air parameters and inlet chilled water temperature，and the characteristics in the VAV system are almost irrelevant with inlet air parameters.
