Air conditioner

Abstract

The application discloses an air conditioner, which comprises a controller, wherein when a dehumidification instruction is received, the controller is configured to determine a preset time for continuous operation of an indoor fan based on a current operation mode of the air conditioner, and after the indoor fan is controlled to continuously operate for the preset time, determine a target indoor set temperature according to an initial indoor environment temperature and an indoor set temperature; after the air conditioner enters a dehumidification mode from the current operation mode, determine a target set dew point temperature according to the target indoor set temperature and a target indoor set humidity; determine a current dew point temperature according to a current indoor environment temperature and a current indoor environment relative humidity; adjust a rotating speed gear of the indoor fan according to the target set dew point temperature and the current dew point temperature; and control an operating frequency of a compressor according to a current outdoor environment temperature, the current indoor set temperature, the current indoor environment relative humidity and the target indoor set humidity, so as to improve the use comfort of a user and the energy-saving effect of the system.
