Methods of Freeze Protection for Fruit Trees by Means of Renewable Energy Sources

As the Earth climate changes, current horticulture gives rise to an acute issue - protecting fruit trees from spring frosts and their root system freezing in severe winters with little snow. The authors substantiated methods of how protect frost freezing, as well a method control phenological phases based on study heatmass- exchange intensification certain soil area occupied by tree various engineering aids be designed. aforesaid is operation heat cold separator, which makes it possible intensify transfer expand specific loads removed using coolant potassium salt brine (aqueous 30% KCL solution). test results have shown that heated temperature 12°С, gradually moving up at depth 0.9 m, heats 7°С 0.5 m 1°С surface earth ambient 10°С. lower layers comes surface; system, redistributed, stabilized state excludes tree. A rational value effective head has been determined equal 2200 Н/m2 1 flow about 4•105 W/m2. In addition, rate set (1.5 ... 2.5) Gmin produce more optimal additional body force separator. controlling heating or cooling installation generates power renewable resources (solar energy, wind biogas plant), depending climatic conditions terrain.
