power heater heats a heat medium by means of the rotation of the rotor. The heat medium heated by the wind
power heater is collected in the heat collection tank. The apparatus for converting building wind
power to a heat source according to the present invention uses the wind
guide and allows the wind
to flow at a high speed into the rotor of the apparatus for converting building wind
power to a heat source so that heating efficiency of the apparatus for converting wind
power to a heat source is increased. Also, the shape of the wind
guide is optimized according to the environment in which the wind
guide is installed so that more heat can be produced using the same amount of wind
. Also, an eddy current is produced following the rotation of a permanent magnet so that the permanent magnet arranged in the rotor in a heat medium heating structure is optimized and energy conversion efficiency is increased.
