In the case of rising temperatures in summer, how to properly cool the Venlo glass greenhouse is an important task of daily management.

Next, we will introduce to you the six common measures for cooling the common Venlo glass greenhouses:

(1) External shading system

It is to block the excessive sunlight outside the Venlo-type glass greenhouse to form shade, protect the crops in the Venlo-type glass greenhouse, and maintain the proper temperature in the shed. This can effectively block the growth of crops from direct sunlight without affecting the natural ventilation of the Venlo glass greenhouse. The cooling effect is better than the internal shading, but the external shading materials are required to be strong, durable, small in scalability, and anti-aging.

(2) Micro mist system

The main purpose is to spray water into the shed in the form of mist particles. The mist particles evaporate quickly and can quickly take away the heat in the air, and then discharge the moist air outside the shed to achieve the purpose of rapid cooling. At the same time, an induced draft fan is installed on one side of the Venlo glass greenhouse to perform forced ventilation and cooling to achieve the cooling effect of the temperature curtain, the temperature is more uniform, and the service life is longer than that of the temperature curtain.

(3) Roof whitening

The white reflection effect is the best. A white coating is formed on the surface of the Venlo glass greenhouse, which can reflect the sun well and prevent a large amount of heat from entering the Venlo glass greenhouse. It can also convert the sun entering the greenhouse into astigmatism that is beneficial to the growth of crops. Growth is very favorable.

(4) Groundwater circulation

At night, the underground cold water can be circulated through the ground cooler, and the induced draft fan can be added to achieve the cooling effect at night, and the air humidity in the Venlo glass greenhouse cannot be increased at the same time. Groundwater resources can also be used. Coupled with a cooling unit, it can not only cool down and heat, but also protect the environment and save energy, but the current cost is too high.

(5) Wet curtain cooling

Curtain cooling refers to the process in which the external high-temperature air passes through the wet curtain, humidified and cooled to form cold air, absorbs the residual heat through the control room, and then discharges it outside the door. 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, it starts the fan and draws out the hot air in the Venlo glass greenhouse to cool down.

(6) Natural ventilation

Naturally adopted methods have three main advantages: one is to remove residual heat in the shed and lower the temperature; the other is to remove excess water and reduce the humidity in the shed; the third is to adjust the content of indoor air components and increase the carbon dioxide content in the air to improve photosynthesis . At the same time, attention should be paid to increasing the ventilation area, which can be used to open the continuous butterfly windows on the top of the Venlo glass greenhouse and increase the ventilation area of the surrounding side windows. In this way, in the less hot spring and autumn seasons, the natural ventilation of the side windows and top windows can be used to cool down the temperature.
