Claim 8:
9. An air conditioning system comprising:
a sensor that measures air quality in an indoor space;
an activity amount measurer that measures an activity amount of a person staying in the indoor space;
an obtainer that obtains information indicating the air quality in the indoor space, and activity amount information indicating the activity amount of the person, the information being output by the sensor, the activity amount information being output by the activity amount measurer; and
a controller that calculates an air quality index based on the information obtained and the activity amount information obtained, and controls a ventilator that ventilates the indoor space, based on the air quality index calculated,
wherein the air quality index is expressed by f(Xn)×g(T, H)×h(A), where f(Xn) denotes a function with respect to Xn that indicates at least one of a carbon dioxide (CO2) concentration, a concentration of total volatile organic compounds (TVOC), a concentration of particulate matter (PM), a nitric oxide (NOX) concentration, a sulfur oxide (SOX) concentration, a trioxygen (O3) concentration, a mold count, or a dust count, g(T, H) denotes a function with respect to T denoting temperature and H denoting humidity in the indoor space, and h(A) denotes a function with respect to A denoting an activity amount, and
when the activity amount indicated by the activity amount information is greater than or equal to a reference amount, the controller decreases a temporal change rate of the air quality index to a predetermined value or less by causing an air conditioner disposed in the indoor space to operate, and thereafter brings the air quality index close to a target range by causing the ventilator to operate.
