摘要： A heat pump air conditioner includes an outdoor unit (70) for heating use only for supplementing heating capacity when additional heating capacity must be provided to the heating capacity of an outdoor unit (50) for heating and cooling in a heating mode. Since the outdoor unit (70) for heating use only is installed independent from the outdoor units (50) for heating and cooling use, such that the outdoor unit (70) for heating use only can supplement the heating capacity only when the additional heating capacity is required in addition to the heating capacity of the outdoor units (50) for heating and cooling use in the heating mode, in order to correspond to the heating load in cold climes, there is no need to install an outdoor unit having larger heating capacity than the required heating capacity. Thus, costs for installation and management are reduced.
