Background

In recent years, facility agriculture (greenhouses, protected field cultivation and the like) has a great proportion in agricultural production, and has positive significance for improving the living standard of people in China. Many problems have arisen at the same time as the large-scale development of the facility industry. By utilizing the warming effect of the facility covering, the cultivation time of facility crops is prolonged, the yield of the crops is improved, and the economic benefit is greatly improved. However, in facility cultivation in late spring and early autumn in many areas of our country, the temperature in the facility is greatly increased due to the influence of high temperature and strong light, and the temperature often exceeds the optimum temperature for crop growth. Thereby affecting the growth and development of crops and even causing the yield reduction of crops. Therefore, the method effectively regulates and controls the overhigh temperature in the facility, prolongs the growth time of the crops in the high-temperature season, and has important significance for the current facility production.

Due to the actual production needs, the cooling measures commonly used in the current facility production mainly include three types: 1. ventilating; 2. shading light; 3. and (5) evaporating, cooling and reducing the temperature. The natural ventilation method is a common cooling mode in facility production, although the natural ventilation method is economical and convenient, the cooling effect is limited, and the cooling requirement in high-temperature seasons cannot be met; the forced ventilation method has more obvious cooling effect than the natural ventilation method, but has higher equipment investment and maintenance cost. The shading method is similar to the natural ventilation method. The evaporative cooling method comprises a spraying system, a wet curtain fan cooling system and the like. The heat absorption is mainly utilized in the water evaporation process, so that the heat in the facility environment is reduced, and the cooling effect is obvious. However, the wet curtain fan system used in the current production needs higher cost and is not movable, only suitable for large-scale multi-span greenhouses, and has more limitation conditions.
