PURPOSE: A heat pump, a device for preventing an implantation of the heat pump, and a controlling method thereof are provided to minimize the heat of an auxiliary heat exchanger required for heating air, thereby perfectly preventing the implantation without the degradation of a heating capacity. CONSTITUTION: A heat pump comprises a compressor, an auxiliary heat exchanger(210), an indoor unit coil, an outdoor unit coil(500), an air distribution duct(730), an air distribution tube, an air sparing slot, an electronic valve, a suction pipe(700), an auxiliary blower(710), a temperature sensor, a controller(910), an accumulator. The auxiliary heat exchanger circulates refrigerant compressed by the compressor at high pressures if a condition is not for implantation and performs a heat exchange between the refrigerant and air if the condition is for the implantation. The indoor unit coil is arranged in the rear part of the auxiliary heat exchanger, thereby taking a role of an evaporator in the cooling operation of the heat pump and a condenser in the heating operation of the heat pump.
