项目摘要

The effective use of a fogging system for the cooling and the spraying of agricultural chemical were investigated, and the following results were obtained.1)Tmperature and humidity environments in a cooling greenhouseCharacteristic of temperature and humidity environments inside the evaporative fog air cooling greenhouse, when fog was sprayed intermittently by a fogging system, were investigated.2)Analysis of ventilation rateVentilation rate, which affect the temperature and humidity inside the evaporative fog air cooling greenhouse, was measured with the traditional greenhouse and the large scale Venro-type greenhouse. The values of ventilation rate for several commercial greenhouses were obtained from the measurement.3) Method of controlling an evaporative cooling systemThe fog is sprayed intermittently from the nozzles in general operating method. The effect of the fogging time and interval time on environments inside the greenhouse was investigated. Changes in temperature and humid … More ity, and an amount of un-evaporated fog decreased with decreasing the fogging and interval time under the condition of same amount of spraying water per hour.4)Development of an evaporative cooling support softwareThe Ventilation-Evaporation-Temperature-Humidity (VETH) chart is useful in the design of evaporative cooling operations, because the relationship between. the four factors (ventilation, evaporation, temperature, and humidity) is easily determined from the chart. The software for the personal computer that can draw a VETH chart, as well as software that can calculate the necessary water spraying rate, were developed. Such software packages are useful as tools in the design and operation of evaporative cooling systems.5)Characteristic of agricultural chemicals adhesion on a leaf surfaceCharacteristic of the agricultural chemicals adhesion on the upper and lower surface of a leaf was tested by using a water sensitive paper. The degree of adhesion on the lower surface of a leaf was very few comparing with that on the upper surface of a leaf. The degree of adhesion on the lower surface of a leaf increased slightly by air circulation with the fan operation. Less

本文研究了喷雾系统在降温和农药喷洒中的有效应用，得到了以下结果：1）降温温室内的温湿度环境研究了喷雾系统间歇喷雾时蒸发式雾空气降温温室内的温湿度环境特征; 2）通风量分析影响蒸发雾风冷温室内温度和湿度的主要因素进行了对比试验。通过对几个商业温室的通风量的测量，得到了通风量的值。3）蒸发冷却系统的控制方法在一般的操作方法中，雾是从喷嘴间歇地喷射的。研究了起雾时间和间隔时间对温室内环境的影响。温度和湿度的变化 ...更多信息蒸发冷却辅助设计软件的开发通风-蒸发-温度-湿度（VETH）图在蒸发冷却设计中是很有用的，因为VETH图中的通风-蒸发-温度-湿度（VETH）与蒸发-温度-湿度（VETH）之间的关系可以很好地描述。这四个因素（通风、蒸发、温度和湿度）很容易从图表中确定。开发了可绘制VETH图的个人计算机软件，以及可计算所需喷水量的软件。这些软件包可作为蒸发冷却系统设计和操作的工具。5）农药在叶片表面上的粘附特性通过使用水敏纸测试农药在叶片的上表面和下表面上的粘附特性。与叶片上表面相比，叶片下表面的粘附程度很小。叶片下表面上的粘附程度随着风扇操作的空气循环而略微增加。少
