Air conditioning system

Provided is an air conditioning system that achieves energy conservation and comfortableness. In the air conditioning system (100), an outdoor-air conditioner (10) sucks outdoor-air (OA) and supplies the outdoor-air as supply air (SA) from an air handling unit (30). An indoor-air conditioner (50) cools or heats indoor-air (IA) that is an air inside a target space (SP) by using an indoor unit (70) and supplies the air to the target space (SP). A general control unit (90) controls performs cooperative load control in which an operating capacity of the outdoor-air conditioner (10) and an operating capacity of the indoor-air conditioner (50) are controlled in cooperation in accordance with a status of the outdoor-air (OA), a status of the indoor-air (IA), an operation status of the outdoor-air conditioner (10), and/or an operation status of the indoor-air conditioner (50). The general control unit (90) controls, in the cooperative load control, at least one of a parameter of the outdoor-air conditioner (10) and a parameter of the indoor-air conditioner (50) such that a temperature or humidity of the indoor-air (IA) approaches a set value and also a total amount of power consumption of the outdoor-air conditioner (10) and power consumption of the indoor-air conditioner (50) is reduced.
