Greenhouse roller shutter machine adjusts the temperature in the shed

Our greenhouse roller shutter machine can adjust the temperature in the greenhouse. What is the principle of this situation?

1. The sun is very good during the day, the sun is full, and the temperature outside is minus 5 degrees. If the film of the greenhouse is not broken, the temperature inside will still be above 25 degrees, so the ground temperature can also be raised to about 15 degrees;

2. In the dark and windy night, the temperature in the shed will be greatly reduced, and it can be reduced to below minus 5 degrees. When the wind is stopped, it can be restored to a lower point than the ground temperature;

3. If a straw curtain is covered at night, the temperature in the shed will basically be equal to or slightly lower than the ground temperature.

Because the vegetable greenhouse is covered with film, the climate is basically self-contained. The temperature of the ground in the greenhouse directly affects the ambient temperature in the greenhouse. If the temperature is high, the soil absorbs the light energy of the sun to increase the ground temperature. At night, it can release energy to increase the temperature inside the greenhouse.
