Heating: Foundation of Year-Round Production

Modern greenhouse heating combines multiple technologies to balance efficiency, reliability, and cost-effectiveness. Central heating systems using hot water distribution through rail pipes or overhead pipes provide uniform temperature distribution with excellent control precision. We typically design dual-zone heating systems, allowing different temperature management for various crop areas or growth stages.

Heat source selection depends on local energy availability and costs. Natural gas boilers remain common, but we increasingly integrate renewable energy systems including biomass boilers, geothermal heat pumps, and combined heat and power (CHP) units. These sustainable options reduce operational costs while enhancing environmental credentials.

Our heating designs consider the thermal properties of your chosen covering materials and the overall greenhouse dimensions to minimize heat loss and ensure rapid temperature response when conditions change. Proper integration with energy screens and ventilation systems maximizes efficiency.

Cooling & Ventilation: Managing Heat Stress

Cooling requirements vary dramatically by location and season, but all greenhouses need effective heat removal systems. Natural ventilation through roof and sidewall vents provides energy-free cooling when outdoor conditions permit. We size ventilation openings to achieve 25-30% of total covering area, ensuring adequate air exchange even during peak heat periods.

Mechanical ventilation fans supplement natural ventilation, particularly in locations with limited wind or during extreme heat events. Pad-and-fan evaporative cooling systems can reduce greenhouse temperatures 5-10°C below ambient, crucial for maintaining crop quality in hot climates. These systems integrate with humidity control to prevent excessive dryness that could stress plants.

High-pressure fogging systems provide rapid, uniform cooling while simultaneously managing humidity. When controlled by sensors monitoring plant transpiration rates and atmospheric conditions, fogging optimizes both climate and plant health. Our designs often incorporate multiple cooling strategies, allowing automated selection of the most efficient method for current conditions.

Humidity & CO2 Management

Humidity control prevents disease while supporting optimal plant transpiration. Excessive humidity promotes fungal diseases and reduces crop quality, while insufficient humidity causes plant stress and reduced growth rates. Our integrated approach combines dehumidification equipment, strategic ventilation, and heating system operation to maintain ideal humidity ranges for your specific crops.

CO2 enrichment significantly increases photosynthesis rates and crop yields, particularly during periods when ventilation is limited. We design CO2 distribution systems using pure liquid CO2 or by-products from heating systems (when using CHP units). Concentration monitoring and control ensure optimal levels throughout the growing area, typically targeting 800-1200 ppm during daylight hours when vents are closed.

Air Circulation: Uniformity is Key

Even with sophisticated heating and cooling systems, proper air circulation ensures uniform conditions throughout the growing space. Horizontal airflow (HAF) fans create gentle air movement that eliminates microclimates, reduces disease pressure, and strengthens plant stems. Our circulation system designs account for crop height, row spacing, and structural elements to optimize air movement patterns.

Proper air circulation becomes particularly crucial in large-scale facilities. Working with findings from site analysis and project scoping, we position circulation fans to complement natural convection patterns while avoiding areas where equipment or plants might obstruct airflow. Integration with climate sensors allows automated adjustment of circulation intensity based on current conditions.
