ABSTRACT:
The air-conditioning apparatus automatically selects one of three operational modes and operates at one of three operational zones defined by a combination of the temperature and the humidity to establish thermally comfortable conditions. In the cooling zone, the air conditioning apparatus operates to control the temperature to lower the temperature; in a dehumidifying zone it operates to control the humidity to lower the humidity; in a fan zone it operates to stir the air to maintain thermally comfortable conditions. The air conditioning apparatus includes an operational mode controller which senses the temperature and humidity and changes the operational mode based upon the sensed temperature and the sensed humidity.
