Frost is a major abiotic stress and one of the principals limiting factors for agricultural production worldwide. Wind machines work in harmony with nature to absorb hot air into the garden or to increase the temperature and protect crops in the agricultural field.
There are two types of frost that can affect crops, advection and radiant. Advection frosts occur when cold air blows into an area to replace warmer air that was present before the weather change. It is associated with cloudy conditions, moderate to strong winds, no temperature inversion and low humidity.
Zirai Don Nedir?
Radiant frost events occur when plants and soil absorb the sunlight during the daytime then radiate and rise the heat during the night when cooler air moves in. Dense chilled air settles into the lowest areas of the canopy, where the most serious frost damage happens. The warmer air that rose above during the night is often trapped in a layer above the crops which is known as an inversion layer.
Radyant Don Olayları
GENER wind machines perform heat transfer with forced convection as they pull the warmer air trapped down into the orchard and mix it with the cooler air down on the surface to raise temperatures and save crops.
Thus, transmission of air mass to a specific distance. Due to being able to rotate also in vertical axis, GENER wind machines circulate the air as to scan an area of 360 degrees and enable the wind movement. Gener Frost Guards consist of a tower, and engine placed in a sealed enclosure, a fuel tank, a control panel and a propeller on the tower. Wind machines have proven to be the most effective solution against frost damages. Contact an expert at GENER to learn more about wind machines.
