Abstract

A controller for controlling an air conditioner comprises a room temperature sensor for measuring a room temperature, a room temperature change computation circuit for computing a difference between the room temperature and a set temperature, an outdoor temperature sensor for measuring an outdoor temperature, a neural network for computing load on the air conditioner according to the temperature change, outdoor temperature, and room temperature, and a controller for controlling, according to the computed load, the operation frequency of a coolant compressor by controlling a compressor motor through a variable frequency circuit, thereby speedily bringing the room temperature to the set temperature and stably maintaining the room temperature at the set temperature. The neural network learns various operation characteristics of a refrigerating cycle of the air conditioner, and according to a result of the learning, controls the air conditioner.
