This study was conducted in order to develop wind-water heating system where frictional heat is created between the rotor and working fluid when they are rotating in the cylindrical heat generator. The wind-heating system is composed of rotor, stator, working fluid, motor, inverter and heat generation tank. Instead of wind turbine, we have used an electrical motor of 30㎾ to rotate the rotor in this system. Two working fluids and six level of rpm were tested to quantify heat amounts generated by the system. Generally, as motor rpm goes up heat amount increases that we have expected. At the same rpm, viscous fluid showed up better performance than the water generating more heat by 10℃ djfference. The greatest heat amount as of 31,500kJ/hr was obtained when the system constantly drained out the hot water of 500 ℓ/hr after heat exchange accomplished. Power consumption rate of the motor was measured by three phase electric power meter where the largest power consumption rate was 14㎾ when motor rpm was 600 and gained heat was 31,500kJ/hr, that indicated total thermal efficiency of the wind power water heating system was 62%. Further study will be carried on after we install a wind turbine that can collect about 15㎾ of wind energy on the system.
