Abstract
Disclosed are a heat pump air conditioning system comprising an additional heater and a method for operating the same, in which the additional heater is driven during a full activation standby time taken to simultaneously operate all of a plurality of compressors so as to rapidly satisfy an increased heating load. When the increased heating load exceeding a total capacity of some compressors selected from the plural compressors is sensed, since the additional heater is driven during the full activation standby time so as to rapidly satisfy the increased heating load, the air conditioning system improves heating effectiveness and uniformly maintains room temperature, thereby improving users' comfort.
