Airconditioner control method

摘要

PURPOSE: A method for controlling operation of an air conditioner is provided to control stop operation when internal pressure of a cycle is at optimum condition. CONSTITUTION: A method includes the steps of: a step(320) dropping operating frequency of a compressor to fixed value stepwise for stopping operation of an air conditioner; a step(330) controlling opening angle of an electronic expansion valve to the maximum; a step(340) determining whether internal pressure of a cycle is controlled to be plain pressure; and a step(350) stopping the compressor after the internal pressure of the cycle is controlled to be the plain pressure.
