作を繰り返すものである。 The operation of the above configuration will be explained with reference to FIG. 3. First, the temperature setting mechanism 1 sets the set value T s
is determined, and when the air conditioner starts operating by an operation switch (not shown), the computer 11 compares the room temperature T R input from the temperature sensing mechanism 2 with the set value T s , and if T R > T s, the terminal Q is 1 and Q2 output continuously to operate the compressor 12 and indoor fan 13 for cooling operation. When T R ≦T s , the output from the terminal Q 1 is stopped and the compressor 12 is stopped. Thereafter, the timer mechanism 5 operates and the room temperature TR is input multiple times during a predetermined period of time until the timer expires, and the arithmetic mechanism 6 calculates the average of multiple temperature increase rates. After time-up, the second determination mechanism 7 compares this temperature increase rate with a predetermined value that has already been set, and determines the temperature increase rate>
In the case of a predetermined value, the timer mechanism 5 is reset and the same cooling operation as described above is performed again. If the temperature rise rate ≦ a predetermined value, a continuous output is output from the terminal Q 1 of the computer 11 to operate the compressor 12, and an intermittent output is output from the terminal Q 2 to operate the indoor fan 13 intermittently to perform dehumidification operation. . Thereafter, the dehumidifying operation is terminated when the humidity becomes below a predetermined value or after a predetermined time by a humidity sensing mechanism (not shown), and the above operation is repeated again.
