A Study of Wind Heating System

Abstract:

At present, the world is facing energy shortage, while the CO₂ emitted from the combustion of traditional energy causes greenhouse effect. As a result, the green concept of energy saving has emerged. Among the current green energies, solar power is not cost effective, and wind energy has great potential in terms of cost and efficiency. Most of wind energy is used for wind power generation, however, the wind energy is also applicable to heating, and the generated heat energy can be used for hot water supply and temperature regulation. The wind heating modes include fluid mixing and solid friction modes. This study used natural wind to design a machine producing heat energy by solid friction. The energy transfer mode of the wind heating system was to convert the blade extracted wind energy into mechanical energy, and use friction to generate mechanical energy generates. The heat energy was transferred to the water through heat exchange to increase the water temperature. The friction mode was to rub the brake pad against the disc to produce heat, and using the compression spring to adjust the magnitude of the friction. The pump circulated water to implement forced convection, and the heat exchange was designed as flowing water channel increasing the heat transfer time. The experimental results showed that the water storage temperature can be increased.
