How to effectively cool down the vegetable greenhouse

One: How to cool down the vegetable greenhouse

When the vegetable greenhouse needs to be cooled, it can be cooled by natural ventilation, shading the sun, and forced cooling.

(1) Natural ventilation cooling is to cool down by opening the greenhouse skylight and side windows through natural ventilation.

(2) Shading the sun to cool down means that in summer, open the inner sunshade net and outer sunshade of the greenhouse to block and reflect the light, so that the shed is not directly irradiated by the sun, so as to achieve the cooling effect.

(3) Forced cooling. In summer, due to the greenhouse effect, the temperature inside the shed can reach more than 50 degrees Celsius when the temperature is high. The environment in the vegetable shed is not suitable for the growth of vegetables at all, and when the above-mentioned shading and ventilation cannot reach the temperature we need, the fan wet curtain is needed for forced cooling, and the effect is still very obvious.
