The greenhouse ventilation system is a vital part of the greenhouse design. Its main purpose is to regulate the air temperature, humidity, and carbon dioxide concentration inside the greenhouse, and to eliminate harmful gases, thereby meeting the needs of normal growth of indoor plants. The ventilation system is one of the measures that must be taken to control the greenhouse production environment.
Greenhouse ventilation systems can be mainly divided into two methods: natural ventilation and forced ventilation. Natural ventilation is achieved by opening the side windows or top skylights of a multi-span greenhouse and utilizing the temperature difference or wind pressure between the inside and outside of the greenhouse to achieve air convection inside and outside the greenhouse, thereby reducing the indoor temperature and humidity. Both the side windows and sunroof can be opened and closed according to needs, and the operation mode is mostly rack and pinion transmission. The side windows are usually made of single-sided or double-sided aluminum alloy sliding windows, and the top skylights are usually set along the roof ridge, and have a variety of opening methods, such as single-sided windows, staggered windows, butterfly windows, etc.
Forced ventilation is a ventilation method that uses ventilation machinery to achieve ventilation when natural ventilation cannot meet the ventilation needs. It is also called fan ventilation. Fan ventilation is usually used to meet the cooling needs of greenhouses, using an exhaust method, that is, negative pressure ventilation, and is often combined with wet curtain cooling. This ventilation method can adopt a longitudinal layout or a horizontal layout ventilation system when the greenhouse roof ridge is longitudinal. In order to prevent outdoor cold air from directly entering the greenhouse and directly hitting the crops, inlet ventilation is generally used for winter ventilation, also known as positive pressure ventilation.
The greenhouse ventilation system is not just a simple window opening or fan opening. It requires scientific and reasonable design and configuration based on the specific structure of the greenhouse, crop growth needs, local climate conditions and other factors. Through a reasonable ventilation system, a suitable crop growth environment can be created, the yield and quality of crops can be improved, and it can also help save energy and protect the environment.
If you need more professional advice on the design of a greenhouse ventilation system, it is recommended to consult the agricultural technology expert Doran Greenhouse to obtain a solution that is more suitable for the actual situation.
