The invention relates to a condensation
prevention control method of an air conditioner, which comprises the following steps: 1, judging the following conditions after starting up: a, whether the set air speed is at a top grade or not; b, whether a compressor is started for the set time T1 or not; c, whether the indoor temperature is more than or equal to the set temperature Ts1 and is less than or equal to the set temperature Ts2 or not; d, whether the temperature of an indoor
machine evaporator is more than or equal to the set temperature Ts3 and is less than or equal to the set temperatureTs4 or not; if one or more conditions are met, executing the step 4, otherwise, executing the step 2; 2, judging whether the actual operational mode is a
refrigeration or dehumidification mode, if not, executing the step 4, if yes, continuously judging whether the compressor is started or not, if yes, executing the step 3, otherwise, executing the step 4; or firstly judging whether the compressor is started or not, if not, executing the step 4, if yes, continuously judging whether the actual operational mode is a
refrigeration or dehumidification mode, if yes, executing the step 3, otherwise, executing the step 4; 3, opening an
electric heating tape by the air conditioner, and executing the step 1; and 4, closing the
electric heating tape by the air conditioner, and executing the step1.
