Technology Overview
1. Product Overview:
Non-Powered Greenhouse Ventilator (NPGV) is an effective and energy-efficient cooling solution for greenhouses. This system utilizes natural principles like convection and wind to remove hot air and circulate cool air within the greenhouse, maintaining suitable temperature and humidity for plant growth.
NPGV Advantages:
- Effectiveness: NPGV can significantly reduce greenhouse temperatures, especially during hot sunny days.
- Energy Efficiency: This system does not consume electricity, saving operational costs.
- Easy Installation and Maintenance: NPGV is relatively simple to install and maintain.
2. Product Features:
- Reduce heating costs in winter: In general, temperature in a greenhouse is kept at 13~20°C depending on the crops but after installing the fan, bacterial diseases are prevented even if the temperature is lowered by 2~5°C. If the non-powered fan is set to 20~22°C, you can maintain the temperature in a greenhouse at 25~29°C without opening the ventilation window until 12:00 a.m.
- Prevention of plastic damage during a typhoon: During a typhoon, the rotation speed of the upper fan of the system is increased to 300-800 rotations per minute, and the strong wind increases resistance to prevent damage to the plastic.
- Promotion of crop growth: Control of high temperature and sufficient ventilation during daytime prevent high humidity, and the sufficient wind flow prevents unproductive overgrowth of crops.
- Prevention of bacterial diseases: Effective ventilation in a greenhouse prevents bacterial diseases caused by poor ventilation and temperature control.
- Prevention of high temperature: The hot air in a greenhouse is continuously discharged to prevent damage from high temperatures.
- Windowless automation system: Unmanned farming is possible by using a non-powered ventilation fan and non-powered automatic ventilation windows instead of the ceiling ventilation window which needs to be opened/closed manually.
2.1 Reducing heating/cooling costs and extending harvest time
- Heating of a greenhouse in winter: With the non-powered fan installed in a greenhouse, even if the temperature of the greenhouse is lowered by 4-5°C, bacterial diseases that spread at low temperature and high humidity do not occur easily, which can save heating costs by 30-50% in winter.
- Maintaining temperature of a greenhouse in summer: In summer it is very hard to maintain ideal temperatures in a greenhouse, so various cooling devices are used, which may cause an increased economic burden. If the non-powered fan is installed, however, the temperature felt by crops decreases by 6-7℃, so the harvest period is extended by 10-30 days.
2.2 Expected results of introducing the fan
- Unique benefits of introducing the fan
- In winter, no frost falls in a greenhouse with a fan installed due to the airflow at appropriate temperatures.
- There is no sudden temperature change caused by automatic opening/closing, so ventilation can be performed without affecting the crops.
- Unique benefits of introducing the fan
