Room air conditioner

A room air conditioner is equipped with an input switch mechanism having a first switch (15a) which the user presses when he feels hot and a second switch (15b) which the user presses when he feels cold. A microcomputer (10) controls the operation of the air conditioner in response to input signals from the input switch mechanism. When the user presses the first (15a) or second switch (15b), the microcomputer (10) automatically changes the set temperature (Ts) in the direction tending to relieve the user's sense of discomfort. The microcomputer (10) also controls the air conditioner operation so as to temporarily change the temperature of air which is discharged into the room being air conditioned in the direction tending to relieve the user's sense of discomfort. The discharge air temperature can be changed by changing the rotational speed of indoor blowers which discharge air into the room, by changing the rotational speed of the compressor (6), by changing the degree of opening of an electronic expansion valve in a refrigerant loop, or by changing the direction of louvers for discharge air so that the discharge air enters directly into the intake port of the air conditioner.
