ABSTRACT:
A temperature control method and apparatus therefor controls an air temperature in a room by determining an error temperature between a set temperature and an actual room temperature. An auxiliary reference calorie is initially set as a previous state calorie value, an error calorie associated with the detected error temperature is determined by PID operation and a current calorie value in determined by adding or subtracting the previous state calorie value to/from error calorie, and the room temperature is brought to the set temperature using the current calorie value.
