Air conditioning apparatus
First Claim
1. An operational mode controller for an air-conditioning apparatus for controlling the temperature and the humidity comprising:
- a temperature sensor for sensing temperature to produce a first signal substantially corresponding to said temperature;
a humidity sensor for sensing humidity to produce a second signal substantially corresponding to said humidity;
means for combining said first signal and said second signal to produce a third signal substantially corresponding to a sum of said temperature and said humidity;
means for comparing said first signal, said second signal and said third signal respectively with a given first signal substantially corresponding to a given temperature, a given second signal substantially corresponding to a given humidity and a given third signal substantially corresponding to a given sum of said given temperature and said given humidity; and
an actuating means responsive to said comparing means for actuating said air conditioning apparatus for controlling the temperature when said temperature and said humidity exceed said given temperature and said given humidity while said sum exceeds said given sum, for controlling the humidity when said humidity exceeds said given humidity while said temperature is below said given temperature and for stopping control of both the temperature and the humidity when both said temperature and said humidity are below said given temperature and said given humidity while said sum is below given sum.

Abstract
An 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.
