Talking about the cooling method of the greenhouse —— 【Xinxin Wulian】

The temperature directly affects the growth of the four seasons of the crop. In the hot summer, at noon, direct sunlight, the outdoor temperature will generally reach more than 30 degrees. If the crop is in this high temperature environment for a long time, it will cause cell damage, affect its growth, or directly cause crop death. Therefore, when the weather is hot, we need to cool down the greenhouse so that the temperature in the greenhouse can reach a crop growth environment. Common cooling methods are as follows.

温室降温

1. Greenhouse periphery shading and cooling method

The external shading method is a method of covering the outside of the greenhouse with opaque or semi-transparent objects in the hot and sunny summer. It can reduce the exposure of sunlight to the greenhouse. Large-scale shading can effectively reduce the inside of the greenhouse. Temperature, and different shade materials can meet different shade effects. The external shading means is simple and easy to operate and is cool in summer. However, when using the external shading method, it should be noted that the place where the shading material and the film are in contact with each other due to the high temperature will cause the film to age faster.

2. Wet curtain cooling method

Wet curtain cooling is a very effective means of cooling. It sends water to various wet curtains in the greenhouse through a conveying system, and then blows water mist into the air through a blower, and uses the principle of moisture evaporation to absorb heat to reduce the temperature of the air environment. Wet curtain cooling can not only have a good cooling effect, and can effectively clean the air in the greenhouse, but also spray some water droplets on the surface of the leaves, so wet curtain cooling is also a good summer cooling method.

3. Cooling method of intelligent air conditioner (fan)

The cost of the smart fan and air-conditioning cooling method is higher than the other two methods. In the Xinxin IOT temperature and humidity monitoring system , the user can set the upper and lower limits of the system's temperature based on the historical data of the system. When the sensor detects that the temperature is higher than the upper limit, the system automatically controls the air conditioner (fan) to turn on for the greenhouse When the sensor detects that the indoor temperature is lower than the lower limit, the system controls the air conditioner (fan) to turn off. In short, it will always keep the temperature in the greenhouse within this range. This method is increasingly used in modern intelligent temperature and humidity monitoring systems .
