Abstract
Description
technical field
[0001] In particular, the present invention relates to the improvement of environmentally controlled greenhouses using compressors, which are generally mass-applicable and require construction and installation. Background technique
[0002] Greenhouses with even the latest technology available face a major problem of lack of cost-effective solutions, making it impossible to achieve cost-effective food production in greenhouses with this technology.
[0003] Enumerate some basic problems existing in the prior art below:
[0004] It is almost impossible to maintain the relative humidity of the air in the greenhouse precisely at the set value. Water molecules evaporate into the air until equilibrium is reached, and if the temperature rises to a certain air relative humidity value, the air expands and can hold more water, which is a drop in relative humidity. Also, at a certain relative humidity level, if the temperature drops, the air inside the greenhouse wil...

Embodiment Construction
[0108] According to a first embodiment of the invention, a plurality of sensors are installed in the greenhouse, namely a solar radiation sensor, a temperature sensor, a relative humidity sensor and a carbon dioxide sensor.
[0109] The atmospheric weather station is equipped with an atmospheric solar radiation sensor, an atmospheric air relative humidity sensor, an atmospheric air temperature sensor, a wind speed sensor and a rain detector.
[0110] When the wind speed exceeds the normal weather station wind speed, the speed sensor triggers the automatic roller of the roof to open / close the insulation board and the blackout material external screen. When the high wind speed cannot be detected or disappears, the roof automatic roller will open / close the insulation board and the external curtain of the shading material to return to the original position (indoor).
[0111] When the weather station rain detector detects rain, the atmospheric rain detector will trigger the roof auto...
