When an operation is switched from a separate heat source air-warming operation for performing indoor air-warming by using a separate heat source section (70) to a heat pump air-warming operation for performing indoor air-warming by using a heat pump section (60), a control unit (8) of an air conditioning system (1) starts the heat pump air-warming operation while the separate heat source air-warming operation is continued, and after an overlapping air-warming ending condition is met, the control unit ends the separate heat source air-warming operation. |
