Claim 0:
1. An air conditioning system comprising:
a sensor that measures air quality in an indoor space;
an obtainer that obtains information indicating the air quality in the indoor space, the information being output by the sensor; and
a controller that calculates an air quality index based on the 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), 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, and g(T, H) denotes a function with respect to T denoting temperature and H denoting humidity in the indoor space, and
when at least one gas concentration denoted by Xn is higher than or equal to a reference concentration, the controller decreases the at least one gas concentration to a gas concentration below the reference concentration by causing the ventilator to operate, and thereafter causes an air conditioner disposed in the indoor space to operate to bring the air quality index close to a target range.
