A new vinyl greenhouse has been developed that maintains an indoor temperature 2 to 3 degrees Celsius cooler than the outdoor temperature during summer.
The Rural Development Administration (RDA) on Thursday unveiled a new greenhouse model, “High Temperature Enduring Innovative Smart Cooling House,” which could change the concept of existing greenhouses.
The newly developed facility is 4 to 9 meters taller than existing wide-type greenhouses, which are typically 7 meters in height, in order to endure climate change such as heat, drought, and torrential rain.
Inside the greenhouse, a device was installed to provide oxygen and cold water on a cycle, and a large ventilation window was installed in the ceiling.
The new greenhouse also has fog spray, a shade curtain and air-conditioning facilities, which help to lower the maximum temperature in summer by 12 to 13 degrees compared to ordinary greenhouses that rely solely on ventilation.
The RDA planted 10,000 berries and 20,000 roses at the facility from the end of July until October, confirming that both crops have improved in growth and development compared to those grown in regular greenhouses.
