Apparatus and method for controlling air-conditioner

摘要

An apparatus for controlling an air-conditioner for generating a first control signal for controlling an air-conditioner in a minimum operation mode or a second control signal for controlling the air-conditioner for controlling the air-conditioner in a maximum operation mode based on a room temperature and a desired temperature previously set by a user, and controlling an indoor fan and an outdoor fan and compressing capacity of compressors of the air-conditioner in multistage based on the first or second control signal and the outdoor temperature. By controlling compressing capacity of the air-conditioner, a rotation speed of an outdoor fan and an indoor fan in multistage based on an outdoor temperature and control signals for controlling a room temperature, a load coping capability can be enhanced.
