Natural ventilation
Roof and side ventilation can remove heat when external conditions and greenhouse geometry allow. Vent opening area, wind and insect-net resistance should be reviewed.
Integrated greenhouse system
Cooling and Ventilation for Hot-Climate Greenhouses
In hot climates, greenhouse cooling must be designed as a system. Greenhouse volume, ventilation path, temperature, humidity, solar radiation, shading and crop tolerance affect performance.
B2B projects only · climate, crop and project area first
Fan and pad cooling
Exhaust fans and evaporative cooling pads can lower incoming-air temperature when humidity conditions are suitable. Performance is evaluated against local wet-bulb conditions and crop targets.
Shading and heat load
External or internal shading can reduce solar heat gain. The strategy should balance cooling benefit with the crop’s light requirement.
