Ventilation System

Greenhouse ventilation systems are a vital part of a greenhouse, helping to maintain appropriate temperature, humidity and air quality, providing an ideal environment for plant growth. Greenhouse ventilation systems generally include two main methods: side wall ventilation and ceiling ventilation. Side wall ventilation is achieved by setting openable windows or doors on the side walls of the greenhouse. When temperatures rise inside the greenhouse, these windows or doors can be opened to promote air circulation, thereby lowering the temperature and removing excess moisture and carbon dioxide. Proper side wall ventilation can prevent greenhouse overheating, reduce plant transpiration pressure, and facilitate plant growth and development. Another type of ventilation is ceiling ventilation, which is achieved by providing an openable skylight or ceiling at the top of the greenhouse. When the temperature inside the greenhouse rises, the skylight or ceiling can be opened to promote the rise of hot air, thereby achieving air convection and exhausting hot air. This helps maintain the temperature and humidity inside the greenhouse within a suitable range. Modern greenhouse ventilation systems are often equipped with automatic controls that can automatically adjust the opening and closing of ventilation equipment according to changes in temperature and humidity inside and outside the greenhouse. Some systems can also be combined with equipment such as wind speed sensors and humidity sensors to achieve more precise control and ensure that the environment in the greenhouse is always in optimal condition. Overall, a good greenhouse ventilation system is essential for plant growth and control of the environment inside the greenhouse. Through reasonable layout and automated control, the greenhouse ventilation system can provide stable climate conditions, help improve crop yield and quality, and meet the needs of different plant growth stages.
