GLASS GREENHOUSE & PLASTIC SHED COST OF SIX COOLING MEASURES 丨AIXIANG GREENHOUSE

 

With the rise of summer temperature, how to properly cool the greenhouse , become an important work of daily management. Here we will introduce the following six measures.
(A) External shading system
It is to block the excess sunlight outside the greenhouse, forming shade to protect the crops inside the greenhouse, is to maintain the temperature inside the greenhouse at a suitable temperature. This can effectively block the direct sunlight on the crops, while not affecting the natural ventilation in the greenhouse, the cooling effect is better than the internal shading, but the external shading material is required to be sturdy, durable, small stretch, anti-aging.
(B) Micro-fog system
Mainly water is sprayed into the shed in the form of fog particles, so that the fog particles evaporate quickly and can quickly take away the heat in the air, and then the humid air is discharged to the outside of the greenhouse to achieve the purpose of rapid cooling. At the same time in the greenhouse side of the installation of induced draft fan forced ventilation cooling, it can achieve the cooling effect of the temperature curtain, the temperature is also more uniform, longer service life than the temperature curtain.
(C) The roof spraying white
White reflective effect is the best. A white coating is formed on the surface of greenhouse shed, which can reflect the sunlight well to stop a lot of heat from entering the shed, and it can also convert the sunlight entering the shed into scattered light which is beneficial to crops, which is extremely beneficial to crop growth.
(D) Underground water circulation
The use of underground cool water circulation flow through the table cooler, plus the induced fan, can achieve the cooling effect at night, while not increasing the humidity of the air in the greenhouse shed. Can also use underground water resources, plus rising cooling unit, both cooling, heating, and environmental protection and energy saving, but the current cost is too high.
(E) Wet curtain cooling pad

Wet curtain cooling pad is the external high-temperature air through the water-soaked wet curtain, humidification and cooling, and the formation of cold wind, cold wind through the controlled room to absorb waste heat, and then discharged outside the process. It mainly uses the evaporation of water to cool down, because the evaporation of water needs to absorb heat, so that it can take away part of the heat in the shed, and at the same time start the fan, the hot airflow in the greenhouse shed will be pumped out so as to cool down.
(F) Natural ventilation
The method of natural ventilation has three main benefits: firstly, it can eliminate the residual heat in the greenhouse and reduce the temperature; secondly, it can eliminate the excess water in the greenhouse and reduce the humidity; thirdly, it can adjust the content of indoor air components and increase the content of carbon dioxide in the air to increase photosynthesis. At the same time we should pay attention to increase the ventilation area, can be used in the greenhouse greenhouse top of the continuous butterfly open window, while increasing the ventilation area of the side windows around. So that in the spring and autumn not too hot season, through the side window and the top window of the air natural convection ventilation to achieve the role of cooling.
