1. An air conditioning system for controlling air conditioning in a room in accordance with an air conditioning operation instruction received from a user, the air conditioning system comprising:
a ventilation device having a ventilation fan configured to ventilate an entirety of the room; a suspension period timer to measure a suspension period from a time that the ventilation fan stops ventilation operation; and an operation duration timer to measure a duration from a time that the ventilation fan starts ventilation operation;
an air agitation device having an indoor installation circulator fan configured to agitate air in the room;
an air conditioner to control the air conditioning of the room and control operations of the ventilation device and the air agitation device; and
a detection device including a detection sensor configured to detect presence of the user in the room, wherein
the air conditioner includes a control unit having at least one of processing circuit and/or a processor and memory configured to
control operations of the ventilation device and the air agitation device before the user enters the room on the basis of an indoor temperature that is a temperature inside the room, an outdoor temperature that is a temperature outside the room, an operation mode of air conditioning control performed by the air conditioner included in the air conditioning operation instruction, an operating status of the ventilation device, and a detection result provided by the detection device, and
calculate an average value of an indoor ceiling temperature and a floor surface temperature to be set as the indoor temperature, acquire the suspension period and the duration as an operating status of the ventilation device, and control operations of the air conditioner, the ventilation fan, and the indoor installation circulator fan based on the indoor temperature, the outdoor temperature, the air conditioning operation instruction, the operating status of the ventilation device, and the detection result.
