Optimizing greenhouse production in a continental (desert) climate
In a semi-closed greenhouse, air is introduced from a climate chamber into the greenhouse using fans and air hoses. This climate chamber, located along the external wall of the greenhouse, facilitates the circulation of air. During cooling, outside air is drawn into the chamber through a wall of cooling pads. This process allows for the blending of dry, cool air from the outside with the warm, moist air from within the greenhouse before being distributed through the air hoses. The carefully designed hole pattern in the hoses ensures an even distribution of air throughout the greenhouse. This innovative system makes the semi-closed greenhouse particularly well-suited for cultivating crops in continental climates, such as deserts.
Optimizing greenhouse production in a (sub)tropical climate
Mechanical cooling provides a solution for regions worldwide experiencing high temperatures and humidity. This process involves installing warm/cold exchangers in front of fans to gradually cool the greenhouse by recirculating dry, cold air until the desired temperature is reached. This method of lowering the temperature and dehumidification enables the cultivation of high-quality produce in challenging conditions.
Sustainable cultivation in a semi-closed greenhouse
There are two methods of managing ventilation in a semi-closed greenhouse. Air can either be expelled through the greenhouse roof or recirculated from the greenhouse into the climate room before being returned. This enhanced airflow not only improves the microclimate around the leaves but also increases CO2 availability for the plants. The result is an environmentally friendly process that promotes sustainable cultivation.
Food safety
The technical aspects of a semi-closed greenhouse ensure the production of safe, high-quality food. With advanced airflow systems and installations, optimal dehumidification is maintained, preventing mold growth. The greenhouse operates under slight overpressure, which, combined with insect netting, effectively keeps unwanted pests out. This significantly reduces the risks of infestations and diseases, resulting in healthier crops and safer food production.
Optimal results
A semi-closed greenhouse delivers superior crop security through its ideal microclimate, increased sunlight exposure, reduced need for pesticides and fungicides, lower CO₂ emissions, decreased water consumption, efficient heat retention, and minimal dependence on fossil fuels. These advantages translate into lower costs and higher revenues for growers.
