摘要(Abstract):

为分析动态变化过程中空气处理设备参数变化对其换热特性的影响,通过建立表冷器的湿工况数学模型,进行了不同进风参数、送风参数下的空气处理设备换热动特性仿真分析,得出了不同的进风干球温度、进风相对湿度、送风干球温度、送风相对湿度和送风量下空气处理设备的动态换热特性曲线,为制定设备节能运行的控制策略提供参考。
To analyze the influence of dynamic heat exchange characteristics of air handling units in different parameters during their variation,a wet condition model of cooling coil was established.By simulating the dynamic heat exchange characteristics of air handling in different air inlet parameters and air out parameter and obtain the dynamic heat exchange characteristic curve of air handling units under variable air inlet dry-bulb temperature,variable air inlet relative humidity,variable air outlet dry-bulb temperature,variable air outlet relative humidity and air output volume.The paper presents reference to design equipment's control strategy for its energy saving operation.
