PURPOSE: A heat pump is provided to improve condensation performance by applying the whole heat of an outdoor unit coil to a condenser. CONSTITUTION: A heat pump comprises an accumulator, all directional valve, an indoor unit coil, an outdoor unit coil, expansion valves(230-1,230-2), and check valves(240-1,240-2). The accumulator separates liquid coolant flowing in a compressor. In the front and rear of the outdoor unit coil, a three way valve is installed. The three way valve converts coolant flowing direction and makes the three way valve selectively function as a condenser or an evaporator.
