ABSTRACT:
An air conditioning system can automatically increase or decrease a desired temperature of an indoor unit at a variable gradient smaller than the variable gradient per predetermined time of an outdoor temperature. Hence, the user does not have to directly change the desired temperature, thus increasing user's convenience. Also, in the event of a significant diurnal range in temperature, air conditioning sickness can be prevented since an optimum indoor temperature can be maintained. Moreover, the variable gradient of the desired temperature of a room is smaller than the variable gradient of an outdoor temperature, thus keeping the room pleasant.
