1. An automatic humidity control method for an air conditioner depending upon a weather determination, comprising the steps of:
- storing reference data according to weather characteristics for the weather determination in memory;
detecting an outdoor temperature over a certain first time period and storing it in memory for comparing with said reference data;
determining an outdoor temperature variation, an outdoor temperature range, and a temperature preservation time based upon the outdoor temperature detected over a certain first time period for comparing with said reference data for the weather determination and performing the weather determination which determines a plurality of recognizable weather conditions including showery conditions, overcast conditions, and rainy spell or foggy conditions based on a comparison with the reference data according to weather characteristics in response to the step of detecting;
recognizing an indoor humidity setting in accordance with using a shower discrimination routine for discriminating showery conditions, an overcast discrimination routine for discriminating overcast conditions, and a rainy spell or foggy conditions discrimination routine for discriminating a rainy spell or foggy conditions;
performing a dehumidifying operation responsive to the recognized indoor humidity; and
subsequently performing a freeze prevention routine of an indoor thermal exchanger responsive to the indoor humidity setting to prevent freezing of the indoor thermal exchanger during the dehumidifying operation.

Abstract
An automatic control method for an air conditioner which can optimize the indoor temperature and humidity, wherein an adequate dehumidifying operation is performed by recognizing the humidity according to the weather based on the outdoor temperature changes preceived by the outdoor temperature sensor for a certain time period, which provides comfortable surroundings and increases the efficiency of the air conditioner as well by preventing apparatus freeze resulting from a prolonged dehumidifying operation under low temperatures.
