Heat generator driven by a wind turbine on the principle of Joule machines
Wind turbines are frequently used to generate electrical energy. The following thermal-wind generator changes the energy of the wind to heat energy and heats up the heating water.
This uses the principle of the so-called Joule apparatus originally of the demonstration of the mutual relation between the work performed and the thermal energy.
James Prescott Joule, English physicist living in the 19. century and the author of the following apparatus, left to rotate the impeller in a container with water that the friction forces gradually getting hotter and hotter. This device has demonstrated a direct relationship between the work performed and the thermal energy.
The principle of Joule apparatus
The retracting handle is shifted to the weights to the top of the scale of a meter. Subsequently, the weights due to gravity spin the impeller, which by the friction in the water caused an increase in water temperature measured with a thermometer. Practical demonstration device, showing the conversion of mechanical energy into thermal energy.
Description of the device
Heat generator driven by a wind turbine combines vertical wind turbine with a revised Jouleovým machine. In the thermally insulated closed tank is located to the impeller axis connected to the wind turbine. The rotation of the pinwheel spins the impeller submerged in the water in the tank. The movement of the blades of the friction force heats the water.
The tank is connected to the heating system of the building, or the circle of hot water.
As the drive offers Savonius wind turbine, the combination of Savonius-Darrieus turbine, or any other Vertical omnidirectional turbine with sufficient action area, the power for overcoming the resistance of the fluid, and the useful work.
Technology is an alternative to the far běžnějšímu the involvement of a wind turbine with an electric generator, when the building seduces electrical wiring and heating stencil subsequently heats the water in the reservoir.
It is understood that the electrical solution will have the energy losses at the generator, the electrical wiring and the transfer of heat to the heating cartridge. While for the heat generator will be the loss of incurring the loss of heat through the shell of the tank and the hot water line to building.
For the circulation of the heating water is offering the use of samotížného system. However, if local conditions do not permit the use of samotíže, it is necessary to the heating circuit to include the circulation pump.
Pros
Direct conversion of rotary motion of the wind turbine on the warmth compared to the indirect conversion with notnými losses in the case of heating of the electrical energy produced by an electric generator driven by a wind turbine.
The lower the resistance of a liquid compared to "developed resistance" under the electric generator and the associated lighter start, and the better the dynamics of the heat generator.
Risks
Corrosion of mechanical parts placed in the tank with water
Imperfection insulation water tank and insulation of water pipes to the house will bring the heat loss. The long lead pipes and poor insulation can offset the losses of electrical energy in the electric generator and the lead from the moose to the building.
The impossibility of lossless storage of thermal energy in the water at a time when there is no wind.
Greater structural performance of hot-water management compared to cable routing of electrical energy.
Conclusion
The authors of the idea are considering deploying in the winter months in countries where it is necessary to heat the living spaces and are secured by favorable wind conditions. It is important that the systems dependent on solar energy in winter are not able to deliver enough heat – solar panels, or photovoltaic together with the heating cartridge. While the wind in some areas just in the winter intensifies. At the same time put the emphasis on the direct conversion of wind energy into heat compared to generating electricity and the subsequent conversion into heat.
