The invention relates to wind energy and can be used in heating systems and hot water supply of residential and industrial buildings.

Known friction heater containing a tank with the heated environment at the bottom of which has a fixed disk in contact with a movable disk drive via the turbine shaft (A.S. No. 1627790, 1991, the USSR). In a known heater has a limited amount of frictional elements in its design there are no device convergence washable eventually drives and the heat storage device with a phase transition.

Known auger screw feeder comprising a shaft and a helical blade. All screw surface screw is assembled from individual blades (A.S. 395317, 1973, USSR). Known auger consumes electrical energy and is not intended to heat water. The blade's surface and auger have a smooth surface that does not hinder the movement of the environment.

The closest to the technical nature of the claimed solution is the friction heat generator comprising a vertical cylindrical housing with cap and plate, drive shaft, pipes entrance of cold and hot water outlet and hydro (RF Patent No. 2380625). Known heat of complicated design and has a significant number of moving pistons in the cylinders, that is riodic to their rapid deterioration, with problematic replacement.

The task of the present technical solution is to increase the friction between the surfaces and their gradual convergence and increased roughness of the rest of the surfaces involved in the technical transformation of energy into heat.

The task is achieved by the proposed wind friction heat generator, comprising a cylindrical housing with a lid and a bottom, the drive shaft of which the top has a flange is mechanically coupled to the shaft flange of a wind turbine. At the bottom of the lid on the case on the right has the outlet nozzle of hot water to the consumer and to the left at the bottom of the inlet nozzle of the cold water from the municipal water supply system. According to the invention the drive shaft under the cover has a flange rigidly connected to the bottom flange of the screw, and on the sides with a plate having holes for accession to this peripheral screws. The Central screw at the bottom has a hole in which a sliding key installed axis, rigidly connected with a movable disk mounted on the base plate, and having a hole in which the axle rotates freely. Peripheral screws at the top freely placed with a gap of 1.5-2.0 mm in the holes of the plate, and at the bottom are attached disks in contact with the circular disk attached to the bottom. All screws firmly down against the modern hollow ring, filled heat storage substance phase transition. The surface of all augers have an increased roughness.

The drawing shows schematically the proposed wind friction heat generator, in which figure 1 is a General view in section; figure 2 is a bottom heater, top view; and figure 3 is a plate with holes, bottom view.

Wind friction heat generator includes a cylindrical housing 1 with a cover 2 and a bottom 3, the drive shaft 4 whose top has a flange 5 which is mechanically coupled to the flange 6 of the shaft 7 of the turbine (not shown). Beneath the cover 2 on the housing 1 on the right has a nozzle 8 of the hot water outlet to the consumer and to the left at the bottom of the socket 9 of the inlet cold water from a cold water supply. The shaft 4 with the lid 2 has a flange 10, is rigidly connected at the bottom with a flange 11 of the screw 12, and laterally with the plate 13 having apertures 14 for accession to this peripheral screws 15. The Central screw 12 at the bottom has a hole 16, in which the sliding key (not shown) installed axis 17, is rigidly connected with the movable plate 18 is in contact with a fixed disk 19 mounted on the bottom 3, and having an aperture 20, which rotates freely axis 17. Screws 15 top freely placed with a gap of 1.5-2.0 mm in the holes 14 of the plate 13, and at the bottom are attached disks 21 in contact with the annular disk 22, recipiendum to the bottom 3, all screws 15 (4, 6, 8) is fixed at the bottom of the joint hollow ring 23 is filled with the heat storage substance phase transition 24. The disks 18 and 21 as erasing fall under their own weight on the stationary disks 19 and 22. The process of converting mechanical energy into thermal energy will not be interrupted when there's wind. The surface of the screw 12 and 15 have an increased roughness.

Wind friction generator works as follows.

When there is a wind of sufficient strength and powerful wind turbine (rotary, rotary or other) will begin to rotate together with the plate 13 screws 12 and screws 15, will begin the conversion process due to friction of mechanical energy into heat. Valve after the pipe 8 (not shown) remains closed until the temperature of the water in the body 1 of the heat to 60-70C. Then the valve open and with the wind the consumer will get hot water from the said temperature. At the termination of the wind heat storage substance with the phase transition in the ring 23 will send the heat moving in the housing 1 water and some time to maintain its temperature in the interval sufficient for the consumer. Upon resumption of the wind process hot water supply is resumed.

In operation, the heat source disks 18, 21 and 22 will be used up, and the disk 18 by moving the key under his weight will go down and the conversion process will not be interrupted. The number of rings 23 and their volume can be increased up to the optimal value, and thus the user will be able to get hot water to an acceptable temperature.

The proposed wind friction heat generator is compact, simple in design and operation. Drive for him it is desirable to use a wind turbine with a vertical shaft and a reliable performance and capacity. It can find application in areas with enough constant wind load for hot water supply and heating of residential and industrial objects.
