Energy-Saving Insulated PC Sheet Venlo-Type Greenhouse Including Roof Window Opening Systems and Constant-Temperature Heating Equipment
Introdution
The Venlo-type PC board greenhouse is a modular, gable-roofed structure characterized by its use of polycarbonate (PC) panels as the primary covering material. Its key features and advantages include:
- Light Performance: PC boards offer excellent light transmittance (80–90%) while diffusing sunlight evenly. This diffused light reduces the risk of leaf scorching, ensuring uniform growth across all crops, which is particularly beneficial for seedlings and leafy greens.
- Insulation & Energy Efficiency: Multi-layer PC panels provide superior thermal insulation compared to glass, minimizing heat loss in cold weather and reducing the need for excessive heating. This lowers energy consumption and operational costs.
- Durability & Safety: PC boards are shatter-resistant, lightweight, and highly resistant to impacts (e.g., hail, wind) and UV radiation, extending the greenhouse’s lifespan. Their lightweight nature also reduces structural stress, making the design easier to expand or modify.
- Cost-Effectiveness: Generally more affordable than glass in both material and installation costs, making it a practical choice for small to medium-scale operations or regions with harsh weather conditions.
Support systems
Roof Window Opening Systems
Roof window opening systems are automated mechanisms for greenhouse ventilation. These systems control the opening and closing of roof-mounted windows via motors or pneumatic devices, triggered by sensors monitoring temperature, humidity, or CO₂ levels.
They facilitate air circulation, expel excess heat or moisture, and draw in fresh air—critical for regulating the greenhouse microclimate and supporting plant respiration.
Constant-Temperature Heating Equipment
Constant-temperature heating equipment maintains stable, optimal temperatures in greenhouses, especially in cold conditions. It includes boilers, radiant heaters, or heat pumps, paired with thermostats to adjust output.
By keeping temperatures within a target range (e.g., 18–25°C for tomatoes), it prevents frost damage, ensures consistent growth rates, and supports year-round cultivation regardless of external weather.
