This invention provides a method and device for preventing condensation in a wall-mounted inverter air conditioner. The control method includes the following steps: when the air conditioner enters the cooling anti-direct-blow mode, time-sharing frequency limiting control and airflow compensation control are executed simultaneously. The time-sharing frequency limiting control, within the time window before condensation forms, controls the compressor to operate at the highest frequency limit corresponding to the currently set fan speed of the indoor fan to cool and dehumidify; then, frequency reduction is used to further reduce condensation formation.
