The pressure reducing valve is connected to a plastic pipe with holes to distribute the carbon dioxide gas in the greenhouse. However, the cost of this system for replenishing carbon dioxide in the greenhouse is relatively high. Utility Model Content

[0014] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, an automatic climate control system for a greenhouse includes a controller 1. The controller 1 adopts an industrial controller. The input end of the controller 1 is connected to an air temperature and humidity sensor group 11, a soil temperature and humidity sensor group 12, a carbon dioxide concentration sensor group 13 and a light intensity sensor group 14. The output end of the controller 1 is connected to a ventilation fan 21, a sunshade drive assembly 22, a humidifier group 23, a light lamp group 24 and an irrigation control valve group 25. The output end of the controller 1 is connected to a carbon dioxide release pipe network assembly 26.

[0015] In this embodiment, combined with the Figure 2As shown, the carbon dioxide release pipe network assembly 26 includes a carbon dioxide storage tank 261 and a three-way pipe 264. The detection port flange of the carbon dioxide storage tank 261 is connected to a pressure gauge 263. The gas outlet of the carbon dioxide storage tank 261 is threadedly connected to a tank valve 262. Both ends of the three-way pipe 264 are installed with a one-way valve 265. The tank valve 262 and the one-way valve 265 are electromagnetic valves. The tank valve 262 is connected to one of the one-way valves 265 through a pipeline. The third end of the three-way pipe 264 is threadedly connected to a discharge pipe 266. The lower part of the discharge pipe 266 is equidistantly opened with through holes. The aperture of the through holes decreases from the end away from the three-way pipe 264 to the end close to the three-way pipe 264. When When the carbon dioxide concentration needs to be increased, the tank valve 262 and the one-way valve 265 connected to the tank valve 262 are opened, and the other one-way valve 265 is closed. The carbon dioxide in the carbon dioxide storage tank 261 is discharged into the greenhouse through the three-way pipe 264 and the discharge pipe 266, thereby realizing the function of increasing the carbon dioxide concentration. When the carbon dioxide concentration does not need to be increased, the one-way valve 265 not connected to the tank valve 262 is connected to the water source pipeline in the greenhouse and opened, and the one-way valve 265 connected to the tank valve 262 is closed. The water source is discharged through the three-way pipe 264 and the discharge pipe 266 for irrigation. A discharge pipe 266 is used to realize the functions of exhaust and drainage, thereby saving the cost of the greenhouse.

[0016] In the present embodiment, specifically, the communication direction of the one-way valve 265 connected to the tank valve 262 is from the tank valve 262 to the three-way pipe 264 , and the communication direction of the other one-way valve 265 points to the three-way pipe 264 .

[0018] In the utility model, the air temperature and humidity sensor group 11 transmits air temperature and humidity data to the controller 1, the soil temperature and humidity sensor group 12 transmits soil temperature and humidity data to the controller 1, the carbon dioxide concentration sensor group 13 transmits carbon dioxide concentration data to the controller 1, and the light intensity sensor group 14 transmits light intensity data to the controller 1. The controller 1 controls the ventilation fan 21, the sunshade drive assembly 22, the humidifier group 23, the lighting lamp group 24 and the irrigation control valve group 25 according to the data transmitted by the above sensor groups, thereby realizing the function of automatic climate regulation in terms of temperature and humidity, carbon dioxide concentration and light intensity.
