  In most cases, the temperature at 20-25 degrees, humidity in 50-75% is that we want to maintain the plant growth environment in greenhouse. Greenhouse temperature is too high, will cause poor plant growth, quality decline, and even death.In hot weather, because of heat conduction, heat radiation, the temperature in the greenhouse without cooling measures taken to higher than the outside temperature 10-20, the production activities can not be normal. So take effective measures for cooling is achieved in greenhouse production only way of high yield, high efficiency and stable.The vertical ventilation wet curtain fan "cooling combination is the most economical and effective cooling measures for greenhouse in summer.For many years away from the application display, even in the hottest day newspaper, rational design of the installation of wet curtain a fan cooling system still can control the temperature in the greenhouse at about 30 DEG C, which will minimise the adverse effects of high temperature on greenhouse.  



The principle of wet curtain cooling of the Dragon

  Jinlong wet curtain cooling process is performed in the base core in Jinlong paper pad. In the corrugated fiber paper surface with a thin layer of water film, when the outdoor hot air is wind suction machine through the pad of paper, water film on the water will air in the heat absorption and evaporation in the water vapor, so after the cool, moist air into indoor the. The natural process is the wind blowing through the water.The external environment in the air dry bulb temperature and wet bulb temperature are different in each moment. Dry bulb temperature high wet bulb temperature is low, the weather is hot and wet bulb temperature difference is large, as shown in figure.

  The temperature depends on the wet curtain can reduce the air to listen to the wet and dry bulb temperature difference and the efficiency of the wet curtain, product cooling value is the cooling effect, stable operation of the wet curtain is usually constant. It can be seen that in the hot weather, the better effect of the wet curtain cooling, as shown below.


湿帘温室降温设计

  温室的热源来自:热传导、热辐射。热传导和热辐射产生的热负荷取决于天气情况,温室结构和温室的遮荫处理等。所有这些导致温室湿度上升的热量都要通过风来排除,因此适宜的室内通风量是一个良好湿帘-风机降温系统的基础。
以下是计算温室通风量时经常采用的额定通风量经验值:
计算出需要的通风量后,在确定湿帘面积时要考虑在湿帘的面积时要考虑在湿帘的效率、阻力和经济性之间取得适当的平衡。湿帘安装得越多,降温效果固然越好,通风的阻力也越小,但是投资越高;反之亦然。因此根据经验我们建议选取如下的过帘风速:100毫米厚湿帘:1.2-1.5米/秒
