Control method and device of air conditioner and air conditioner

Abstract

The invention provides a control method and device of an air conditioner and the air conditioner and relates to the technical field of air conditioners. The control device of the air conditioner comprises an indoor heat exchanger, and further comprises a control module; the control module is in communication connection with the indoor heat exchanger; the indoor heat exchanger comprises a first heat exchanging unit, a second heat exchanging unit and a communicating unit; the two ends of the communicating unit are connected with the first heat exchanging unit and the second heat exchanging unitcorrespondingly; and the control module controls running of the first heat exchanging unit, the second heat exchanging unit and the communicating unit according to a running mode of the air conditioner. According to the control device of the air conditioner, due to the fact that the indoor heat exchanger is arranged into the two heat exchanging units, when the air conditioner runs in a dehumidifying mode, it is achieved that dehumidifying is performed under the situation that a compressor is not shutdown, the service life of the compressor is prolonged, and the energy consumption is lowered; and meanwhile, the dehumidifying capacity of the air conditioner is enhanced, and the dehumidifying speed is increased.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular, to an air conditioner control method and device, and the air conditioner. Background technique [0002] The air conditioner has three functions of cooling, heating, and dehumidification; the flow direction of the refrigerant in the dehumidification mode of the existing air conditioner is the same as that in the cooling mode, so there is no essential difference between the dehumidification mode and the cooling mode of the existing air conditioner. By controlling the intermittent operation of the compressor in the dehumidification mode and reducing the wind speed of the indoor fan to avoid low-temperature air supply; however, this control method requires frequent start and stop of the compressor, which affects the service life of the compressor. Contents of the invention [0003] The problem solved by the invention is that the air conditioner in the prior art needs...
