Problems solved by technology
However, this equipment has high requirements on the sealing of the greenhouse, high equipment development costs and high energy consumption
[0005] The commonality of the above equipment and methods is that the control function is relatively single, and the problem of dehumidification in winter cannot be well solved. The contradiction between ventilation and heat loss and the problem of poor air circulation

Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the patent of the present invention is further described. The present invention is based on the distributed active circulation greenhouse air quality control system, such as figure 1As shown, the gas circulation device includes a main ventilation pipe (2), a distributed telescopic ventilation pipe (1), an air delivery pipe (9) and a fixed rope (10). The main ventilation pipe (2) is located on one side of the planting area on the ground, and transports gas to the gas improvement device; one end of the distributed telescopic ventilation pipe (1) is connected to the main ventilation pipe (2), and the other end can be freely retracted to enter the planting area. The space between the rows absorbs gas; the air duct (9) conveys the improved gas to the top of the planting area for active circulation; the two ends of the fixed rope (10) are fixed on the walls on both sides of the greenhouse to support Suspension ventilation pipe....

The invention provides a greenhouse air quality regulation and control system and method based on distributed active circulation. The system comprises a gas circulation device, a gas improvement device and a control system, wherein the gas circulation device is used for sucking gas at the bottom of a greenhouse and delivering the gas to be above crops to realize active circulation of the gas fromtop to bottom; the gas improvement device is used for sucking the gas, dehumidifying and warming the gas and increasing the concentrations of CO2 and ozone; and the control system is used for controlling precise operation of the devices. According to an operation method provided by the invention, the control system comprehensively regulates and controls gas circulation in the greenhouse, and the gas circulation device sucks the gas in the greenhouse and releases the improved gas so as to continuously improve the quality of air in the greenhouse, so that production of crops in the greenhouse isguaranteed.
Description
technical field [0001] The invention belongs to the technical field of facility agriculture, and relates to a greenhouse air quality control system and method based on distributed active circulation, which is used for CO2 in solar greenhouses. 2 Concentration and air temperature, humidity adjustment and sterilization and disinfection operations. Background technique [0002] In recent years, my country's facility agriculture industry has developed rapidly, and it has become the world's largest country in terms of vegetable planting area and output in solar greenhouses. Vegetables in facilities are mostly out-of-season vegetables. As a highly intensive production method, solar greenhouses have extremely high economic benefits. However, in production, the solar greenhouse has been in a sealed state for a long time, and the air quality control inside the greenhouse has always been an important issue, which mainly includes: high humidity, especially at night in winter, when the...
