CO2 Fans
1) Homogeneous CO2 Distribution: CO2from injection points or boiler flue gas can be buoyant or dense. The fans actively CO2 the greenhouse air, preventing CO2 stratification (pockets of high/low concentration) and ensuring the gas is evenly delivered to the entire crop canopy.
2) Optimized Photosynthesis: By creating gentle air movement across the leaves, the fans break the "boundary layer" of still air around the plant stomata. This allows the plant to efficiently absorb the supplemental CO2and transpire, directly boosting the rate of photosynthesis and yield.
3) Preventing Climate Variation: The circulation fans ensure the air temperature and humidity are uniform throughout the greenhouse volume.5This prevents cold spots (where condensation and disease thrive) and hot spots, leading to healthier, more predictable plant development.
4) Energy Efficiency: By mixing the air, the fans prevent heat from stratifying in the roof. This ensures the heating system's heat is utilized effectively lower down, reducing heating costs.
