湿帘系统循环运行降温初探

Research the Cycle Running of the Wet Curtain Cooling System

为了有效减小夏季玻璃温室的降温成本，针对减小湿帘风机循环运行降温的成本进行了探索性研究试验。试验结果表明：在夏季高温上午时段，利用Eldar控制系统控制湿帘风机的运行时间，当把温室内的温度设定在32～35℃时，在153min的时间段内，湿帘系统中水泵运行了43min，风机运行了68min；温室内温度与湿度成反比关系，温度越低，湿度越高；Eldar控制系统设定的温度差越大，湿帘风机开启的次数越少，运行的时间也越短。

In this paper, it has the experiment of the cycle running of the wet curtain cooling system that reduces a higher-cost in summer. The results show that in the morning in summer, the Eldar pilot control system is used to set the temperature in 32 - 35℃, pumps of the wet curtain system runs 43 min, fan runs 68min at the 153min time period; the relationship of temperature and humidity in the greenhouse is inversely proportional, the lower the temperature, the higher the humidity; the pan-and-fan opens less time and runs more short when the Eldar control system is used to set the greater difference of the temperature.
