An alternating type heat pump has first to third rows of outdoor unit coils adapted to selectively perform the functions of an evaporator and a condenser in accordance with the outdoor conditions and the load variations, thereby improving the performance of the heat pump, and is capable of allowing the first to third rows of outdoor unit coils to be operated as a condenser in an alternating manner under the conditions where frost on the outdoor unit coils may be formed especially in winter seasons, thereby basically preventing the conditions on which the frost is formed.
