No. 1627790, 1991, the USSR). In a known heater limited amount of rubbing each other technical elements in its design there is no heat storage device with a phase transition.

Known thermoelectric air conditioning, including shrouded elements, water and air heat pipes and fan motor housing in the form of a hollow section, made up of a set of thermoelectric packages cylinder. (A.S. No. 269459, 1970, USSR). Known thermoelectric air conditioning outside consumes electrical energy and its design is not designed to heat water using wind energy.

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, and washupito shaft through the cover and the clutch connected to the shaft of a wind turbine, and at the bottom with the pins connected to the movable eccentric drive motor. (RF patent 2380625, 2010). Known heat friction complicated construction and has a significant number of moving pistons in the cylinders, which leads to premature wear.

The task of the present technical solution consists in increasing the number of rubbing each other technical elements of simple design, and thus in the increase of the coefficient of conversion of one form of energy into another.

The task is achieved by the fact that the proposed friction heat generator comprising a vertical cylindrical housing with cap and plate, drive shaft, pipes entrance of cold and hot water outlet, a moveable disk with blades and a stationary disk. According to the invention the pipe is rigidly attached to the shaft, has a top attached to it on both sides of the beam, and the bottom of the cantilever beam, simply supported on the disk, attached at the bottom of the shaft. The disks on both sides at the bottom of the cantilever beams attached to them, and of which overlook attached vertical rods with line attached disks with blades and disks with hollow rings around them, and the rods at the top is fixed in the sleeve attached to the rocker arm. Hollow ring disk and the container in the form of a truncated cone filled with the warmth of cumwithuscom matter phase transition.

The friction heat generator includes a vertical cylindrical housing 1 with a cover 2 and a bottom 3, the drive shaft 4 whose top has a flange 5 PTO and passes through the bearing 6. At the bottom of the shaft 4 has a supporting disk 7, is rigidly attached, and the movable disk 8 in contact with the stationary disk 9 attached to the bottom 3. The blades 10 attached to the side of the disk 8, made in the form of a propeller and press it to the disk 9. The pipe 11 is rigidly attached to the shaft 4 has a top attached to it on both sides of the beam 12 and the lower cantilever beams 13, supported on the disk 7. The lower disk 14 attached to beams 13, and of which come attached to the vertical rods 15, fixed in the sleeve 16, is attached to the rocker arm 12. The disks 17 with blades 18 and the disk 19 with hollow rings 20 rows in sequence freely mounted on the rod 15 (see figure 1), on their holes 21.

The housing 1 has a left at the bottom of the outlet 22 of the inlet of cold water, for example, from a municipal water supply, and top right is a pipe 23 provided with a system of hot water supply (not shown). All of the disks 8, 9, 14, 17 and 19 are made of solid slowly is washable material, and the blades 18 of the disks 17 are square, gradually increasing down from the rocker 12 and disk 14 mounted on the beams 13. In the lower part of the tube 11, supported on beams 13, installed in the form of a truncated cone tank 24 filled with the heat storage substance phase transition, and the hollow ring 20 disks 19 is also filled with the heat storage substance phase transition.

To the pipe 11 can be attached to 2, 4 or more rocker with 12 beams 13, between which the vertical are 4, 8 or more packages with the disks 17 and 19. These activities contribute to the increase of the conversion of mechanical energy into thermal energy and more rapid heating through heat cold water.

The friction heat generator works in the following way:

In the assembled condition of the heat generator is connected by pipes 22 and 23 to the cold and hot water, and with the flange 5 to the drive motor, such as a wind turbine.

When the wind of sufficient force rotates the shaft 4, the pipe 11, the rocker arm 12 with the beams 13 and packages of disks located between them. At the bottom of the shaft 4 also rotates the disc 8 with the blade 10, in contact with the stationary disk 9, converting mechanical energy into heat due to friction disks together. The heat from all sources is used for heating the liquid, which is looking is moved upward of the housing 1 and heated through pipe 23 is spent on customer needs. Hollow ring 20 discs 19 and the tank 24 with a accumulating substance phase transition continuous operation of the heat generator store heat from passing these fluids. In the temporary absence of the wind they give up their heat to the liquid and thereby maintain its temperature within acceptable limits for the consumer.

The proposed friction heat generator is compact, simple in design and operation, and therefore, in combination with a drive from a wind turbine is known constructions can be widely used in areas with sufficient wind load for heating and hot water supply to various destination object.
