温室湿帘降温系统原理与应用

湿帘降温系统通过空气与水的直接接触,达到室内空气降温增湿的目的.系统具有降温效果明显、设备简单、安装方便、成本低和性价比高等优点,可广泛应用于温室、畜舍等和纺织车间等需要降温增湿的场所中.为此,根据湿帘表面水膜的传热传质特点建立了湿帘降温的理论模型,讨论了湿帘结构和运行参数对降温效果的影响,为温室湿帘降温系统的设计和运行提供了理论依据.

Application and Principle of Wet-curtain Cooling System in Greenhouse

Through direct contact of air and water, wet-curtain cooling system realize air-cooling and humidity increasing indoor. It has some obvious advantage such as remarkable cooling effects, simple structure, convenient installation and cheaper cost. Extensive application of wet-curtain is in greenhouse, livestock and the textile workshop where need lowering the temperature and dehumidification. This paper develops theoretical models by analyzing the process of heat and mass transfer in the water film, and accordingly discusses the effects of structure and operating parameters on temperature. This paper provides the theory basis for design and application of wet-curtain.
