Humidifying and cooling draught fan wet curtain device and control method

The invention discloses a humidifying and cooling draught fan wet curtain device and a control method. A wet curtain and draught fans are arranged on the same side of a greenhouse of the device, therefore, the layout of a traditional wet curtain draught fan is optimized, sun shading of the draught fans on the interior of the greenhouse is reduced, and the daylighting property and the space utilization rate of the greenhouse are improved. The volume of fresh air entering the greenhouse and the circulating air volume in the greenhouse are adjusted through angle change of an air inlet side windowbaffle, therefore, the purpose of precisely regulating and controlling the temperature in the greenhouse is achieved, and the defect that the temperature in the greenhouse dramatically changes when the traditional wet curtain draught fan is started and stopped is avoided. Through positive pressure type cooling design, entrance of pathogeny and insect sources of greenhouse crops are reduced. Air is supplied through ventilation pipelines, and therefore the temperature and the humidity in the greenhouse are evenly distributed. The greenhouse humidifying purpose is achieved through inner circulation of air in the greenhouse and the wet curtain. Feedforward type control is adopted in the control method, and therefore the precision of temperature and humidity control is improved.
