PROBLEM TO BE SOLVED: To make all ventilation/external air treatment, cooling and heating able to be carried out with a heat pump and to make no auxiliary facility such as a heat source machine separately required. SOLUTION: The heat pump air conditioning system is provided with a heat pump type external adjuster B for feeding external air to an indoor air conditioning zone E; and a heat pump type heat recovery circulation air conditioner A for circulating and feeding air in the air conditioning zone E and discharging a part of air in the air conditioning zone E to the outdoor. And, an evaporator 5, a condenser 6 and a compressor constituting a coolant circulation circuit D; an evaporation blast passage 16 in which the evaporator 5 passed through with external air for feeding air to the air conditioning zone is provided; and a condensation blast passage 17 in which the condenser 6 passed through with external air for condensing is provided are provided in a casing of the external adjuster B. And also, an evaporator 2, a condenser 3 and a compressor constituting a coolant circulation circuit C; an air feeding blast passage 14 in which the evaporator 2 passed through with the circulation air in the air conditioning zone E is provided; and an air discharge blast passage 15 in which the condenser 3 passed through with the air for discharge and heat recovery in the air conditioning zone E is provided are provided in a casing of the air conditioner A.
