METHOD FOR CONTROLLING INDOOR TEMPERATURE OF HEATING/COOLING AIR CONDITIONER

摘要

PURPOSE: A method for controlling indoor temperature of heating/cooling air conditioner is provided to precisely control temperature on every five minutes. CONSTITUTION: A method includes the steps of: a setting step(S200) for a user to set desired temperature; a step(S210) executing heating operation according to set temperature; a step(S220) measuring indoor temperature by a sensor installed in an indoor unit; a first determination step(S230) comparing the measured indoor temperature with the set temperature with allowance(Delta T:2 deg.C); a step continuing heating operation according to the set temperature when the measured indoor temperature is lower than the set temperature with the allowance; a step(S140) stopping a compressor and a fan when the measured indoor temperature is higher than the set temperature with the allowance; a second determination step(S250) determining whether five minutes have passed after stopping the compressor and the fan; a step continuing to stop the compressor and the fan when five minutes have not passed in the second determination step; and a step(S260) operating the fan at minimum rotating frequency for five seconds and returning to the step measuring the indoor temperature when five minutes have passed in the second determination step.
