Claim:
1. An air-conditioning system comprising: a heat pump type air-conditioning device; a human detection sensor; an indoor temperature sensor; an outdoor temperature sensor; a ventilating device circulating air in a room and outdoor air; and a controller controlling the heat pump type air-conditioning device and the ventilating device on the basis of detection values of the human detection sensor, the indoor temperature sensor, and the outdoor temperature sensor, wherein the controller sets a target setting temperature for the room, the controller compares a value obtained by subtracting an outdoor temperature detected by the outdoor temperature sensor from the target setting temperature, with a first threshold related to the value, the controller compares a value obtained by subtracting the outdoor temperature from an indoor temperature detected by the indoor temperature sensor, with a second threshold related to the value, the controller compares a value obtained by subtracting an indoor heat load from a cooling capacity, with a third threshold related to the value, the controller controls operation of the heat pump type air-conditioning device and the ventilating device on the basis of these comparison results, and the first threshold, the second threshold, and the third threshold are set in accordance with a number of people detected by the human detection sensor.
