1. An air conditioning controller using thermal sensation of a human as a thermal comfort index, the air conditioning controller comprising:

  • a room temperature-humidity combination calculation unit configured to calculate combinations of room temperature and room humidity corresponding to a target value of the thermal comfort index;

    a temperature-humidity setting value determination unit configured to;

    select a combination of the room temperature and the room humidity that achieves energy saving, in every fixed cycle, from among the calculated combinations, the selected combination minimizing a difference between a room air enthalpy calculated from the room temperature and the room humidity, and an outdoor air enthalpy calculated from an outdoor temperature and an outdoor humidity; and

    determine a temperature setting value and a humidity setting value; and

    a temperature-humidity control unit configured to separately control the room temperature and the room humidity so that the room temperature and the room humidity correspond respectively to the determined temperature setting value and the determined humidity setting value.
