PERFORMANCE ANALYSES OF WIND MACHINES OF DIFFERENT POWER CAPACITIES USED FOR FROST PROTECTION IN AN ORCHARD
In this research, the efficiencies of two different wind machines which were set up for the frost protection in orchard have been investigated. Wind machines are located in 150 da lemon orchard in the south of Turkey. The land is belong to Yuregir district of Adana province. Citrus production is one of the widely-held agricultural activities, and it has economic importance for this region. Frost damages occur from time to time on fruit trees due to the climatic conditions. It is a serious problem for fruit growers, and causes economic losses.
Wind machines are used in the region for reducing this risk. Power capacities of the wind machines used in the lemon orchard were 130 and 172 hp. Temperature and wind speed were measured at the different distances and heights in orchard for the determination of wind machine efficiency. As a result, it was determined that the moving air layer had prevented the trees from frost, and air temperature of the orchard increased between 0.83oC – 2.11oC.
