    • PURPOSE: A heat pump is provided to operate a heat pump by selectively interlocking with a boiler according to an electricity charge by quantity of heat or indoor temperature. CONSTITUTION: A heat pump comprises an outdoor unit(O), a hydro unit(H), a boiler(700), a water-heating tank(800), and a control unit. The outdoor unit comprises a compressor. The hydro unit heat exchanges refrigerants supplied from the outdoor unit with water. The boiler selectively heats water circulating in the hydro unit. The water heating tank heats or stores water supplied from a waterworks by heat exchanged water with the refrigerants in the hydro unit, or stores the water supplied from a waterworks by the boiler after heating. The control unit controls the outdoor unit, the hydro unit, and the boiler.

    • The present invention relates to a motor control device comprising; a power supply unit which supplies power to a motor; a power device which is located between a motor and the power supply unit, and blocks a current when a current more than a current maximum value is flowed; a control unit which controls the size of the current supplied to the motor by the power supply unit; and a load torque sensing unit which senses load torque generated in the motor when the motor is rotated. The control unit controls the the maximum value of the current supplied to the motor to be lower than the maximum value of the current and controls the an acceleration amount of a motor rotating speed generated during the first round of the motor to be equalized to a deceleration amount of the motor rotating speed if the maximum value of the load torque sensed by the load torque sensing unit is the current maximum value or greater. The excitation generated in the motor is minimized through the present invention even if the motor is in a saturation state.

    • PURPOSE: A heat pump having a boiler and a control method thereof are provided to offer a efficient heating or water-heating function to users by using a boiler when indoor temperature is lower than a pre-set temperature. CONSTITUTION: A heat pump(1000) comprises an outdoor unit, a hydro unit(H), a boiler(700), a heat-radiating heating unit(600), and a control unit. The outdoor unit compresses refrigerants. The hydro unit heat exchanges the compressed refrigerants and water. The boiler heats water circulating the hydro unit or supplied from a waterworks. The heat-radiating heating unit proceeds heating by heated water in the hydro unit or boiler. The control unit controls the outdoor unit, the hydro unit, and the boiler according to an electricity charge by quantity of heat or indoor temperature.
