车间湿帘降温系统热湿交换的研究

Study on Heat and Moisture Exchanges in Wet-curtain Cooling System

根据空气降温增湿后对人体舒适性影响很小的特点,在某生产车间设计和安装了湿帘降温系统,通过空气和水在湿帘纸表面的传热传质特征,建立湿帘降温系统的降温增湿模型,系统测试表明,降温增湿模型能准确地反映空气通过湿帘后温度和湿度的变化,为湿帘系统设计提供了理论依据。

According to the little influence of air cooling and humidity increasing on the comfort of human body, a wet-curtain cooling system was designed and installed in a costume production workshop. Cooling and humidity increasing model of the system was built based on the heat and mass transferring characteristics between air and water on the surface of wet-curtain. Systematic measurement proved that the developed model could accurately predict the temperature and humidity variations after air passing through the wet curtain, it provided a theoretical reference for designing wet-curtain system.
